The Avocent® Universal Management Gateway appliance serves as a single point for secure local and remote access and administration of target devices. The Avocent® Universal Management Gateway appliance supports secure remote data center management and out-of-band management of IT assets from any location worldwide. It provides keyboard, video and mouse (KVM) capabilities and can also remotely perform server management tasks, including power control and console access, on managed target devices. Multiple administrators can be logged into the appliance at the same time and can use the web user interface (UI), the command line interface (CLI) or DSView™4 management software to access and configure the appliance. NOTE: All instances of DSView™software in this document refer to DSView™software version 4.5 or higher. The Avocent® Universal Management Gateway appliance combines KVM over IP, Service Processor Management (SPM) and access and serial console management access. It gives you flexible target device management control and secure remote access from anywhere at anytime. 1.1 Features and Benefits 1.1.1 Secure access You can securely access the appliance through the following local (analog console port) and remote (digital IP) options: • LAN/WAN IP network connection. • Serial target device connection. An authorized user can make a Telnet, SSH v1, SSH v2 or raw connection to a target device. For Telnet or SSH to be used for serial target device connections, the Telnet or SSH service must be configured in the Security Profile that is in effect. • Console connection. An administrator can log in either from a local terminal or from a computer with a terminal emulation program that is connected to the console port and can use the CLI. 1.1.2 Autosense The Avocent® Universal Management Gateway 2000 appliance has eight autosensing ports that can be used for either service processor (SP) or serial connectivity and management. It has an additional 32 RJ45 ports which are intended solely for SP connectivity and management. The Avocent® Universal Management Gateway 4000 and 6000 appliances have 40 autosensing ports that can be used for service processor (SP) or serial connectivity and management. Ports that support autosensing are designated on the back of the appliance with a small turquoise line next to the port number. Ports indicate which mode of operation is currently active with a green or amber connection LED. By default, all ports capable of autosensing are in automode. It is recommended to leave the port set to autosense. This is indicated by having both the green and amber LEDs illuminated. If a port is statically set to one of the two modes, the corresponding LED will be the only one illuminated. Figure 1.1 Autosensing Port Network and serial mode The autosensing ports can operate in network or serial mode. Each major mode has sub modes called port classes. The network port class is for network or SP connections. The port will autosense network targets but will need to be manually configured for SP connected targets. The serial port class is for console connections or PDU connections. By default, the serial port class will autosense to a console connection and will need to be manually configured for a Power Distribution Unit (PDU) connection. The ports will autosense and switch to the appropriate mode depending on the target attached to the appliance. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 1

device attached to it. It is only intended to be connected to the device to be managed or accessed. The appliance will not function as a traditional network switch or common network access firewall. It is a special purpose appliance intended for target device access and management. CAUTION: Since the appliance issues IP addresses using DHCP, they could conflict with a production DHCP infrastructure. Proper VLAN segmentation must be assigned on the network to avoid this conflict. IP addresses can also be assigned statically to SPs, and the appliance can scan IP ranges to discover them. When a port is in serial mode, the amber LED will be illuminated. The appliance will assign the console port class by default and auto-detect whether to apply the Avocent® or Cisco® soft pinout. The speed, flow control, parity and data-size are all predefined for connectivity to standard RS232 server consoles but can be modified on a per-port basis. In addition to console mode, a supported Avocent® PDU can be connected to and managed from the appliance. 1.1.3 Web user interface (UI) Users and administrators can perform most tasks through the web UI (accessed with HTTPS). The web UI runs in Microsoft Internet Explorer® and Mozilla Firefox® browsers on any supported computer that has network access to the appliance. An administrator can use the web UI to create user accounts, authorize groups and configure security and ports. Authorized users can access connected devices through the web UI to troubleshoot, maintain, cycle power, or to reboot connected devices and change their password. For more information on the web UI, see Web User Interface on page 19. 1.1.4 VGA and USB connections Standard VGA and USB connections can be used to attach an LCD tray. These ports are located on the front of the appliance. The VGA console port can be used for launching sessions to targets or for performing NetBoot firmware recoveries.

manage the appliance and its associated targets. NOTE: The actions in this section can be performed by first clicking the Administration tab. Figure 5.1 Administration Tab Overview 5.1 Appliance Settings From the sidebar, click Appliance Settings to view the appliance model, serial number, firmware version and power supply status. You can enter or edit contact, location and help file settings as well as configure email settings. You can use the buttons at the top of the screen to reboot, shut down or launch an SSH session to the appliance. WARNING! Always execute the shutdown command through the web UI, CLI or DSView™software under the Overview/Tools node before turning the appliance off, then on again. This will ensure the reset doesn't occur while the file system in Flash is being accessed, and it helps to avoid Flash memory corruptions. 5.1.1 SSH Click SSH to launch an SSH-based CLI console session from your PC to the appliance. From here you can access the Administration CLI, target sessions and power actions, as well as access the appliance Linux Shell. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 23

You can access the online help for the appliance by clicking the Help button in the top right of the screen. If your client PCs do not have internet access, you may download a PDF of the appliance user guide and host it on an internal web server. To download the user guide, go to www.VertivCo.com. Once you've downloaded the user guide and hosted it on a server, enter its path in the Help File URL field. 5.1.3 Email Settings The appliance can generate email alerts for events that occur on the appliance or its associated target devices. Once an SMTP/email server is configured, alerts can be sent to as many as four email addresses. See Monitoring on page 67 to configure alerts and their email recipients. 5.2 Defaults From the Defaults tab, you can restore the appliance to its factory default settings. You can also configure the date and time, NTP server settings as well as setting the time zone and daylight savings. If you do not have access to an NTP server, you can manually set the date and time. NOTE: You have to set the time on the appliance before enrolling it in the Trellis™Real-Time Infrastructure Optimization platform. 5.3 Network Settings Click Network Settings to configure the hostname, DNS, domain name, IPv4 default gateway and IPv6 default gateway. 5.3.1 Network modes The appliance provides agentless remote access and control. No special software or drivers are required on the attached servers or client. The appliance has three physical network interfaces (eth0, eth1, priv0). Each interface has an individual MAC address and can be configured for normal or failover modes. Only the public GB1 (eth0) and GB2 (eth1) are visible to the user interface. The 40 private target ports are virtually configured to connect through the internal priv0 interface. To configure individual ports, see Port configuration on page 36. NOTE: Changes to the appliance network mode will invalidate default firewall rules and can interrupt communication with the appliance. See the following for more information. Placing the appliance into Failover mode or adding eth0 or eth1 to a Bridge group will disable the IP addresses currently assigned to some/all appliance interfaces. New interfaces will be activated (Failover = bond0, Bridge group = ). By default, the new interface will not inherit any former IPs assigned to either eth0 or eth1. For best results when placing an appliance in Failover mode or creating a Bridge group, the operator should perform the configuration changes via the VGA  console or the serial Setup port to avoid losing communication access to the appliance. All firewall rules that reference interfaces replaced during the network configuration change should be edited to ensure proper network communication when operating the appliance in the new mode. This means eth0/eth1 must be replaced with bond0 where applicable. NOTE: The default IP addresses for the appliance are: GB1 (eth0) = DHCP, GB2 (eth1) = 192.168.1.10. Normal In Normal mode, the public interfaces and the public target ports are separated by a firewall. GB1 and GB2 function independent of each other and can assume individual IP addresses. Only a single gateway can be defined for the appliance, but static routes are helpful for enabling the appliance to communicate with various subnets from either interface. For example: An appliance with GB1 connected to a 192.168.200.x/24 network with a gateway of 192.168.200.1. GB2 is connected to a 10.1.0.x/24 network with a gateway of 10.1.0.1. If the default gateway for the appliance is set to GB1 (eth0), then the appliance will not be able to communicate with other 10.x.x.x networks via the gateway assigned to GB2. A static route can be added to the appliance indicating that 10.1.0.1 should be used to communicate with all 10.x.x.x subnets. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 24

common bond0 virtual interface. Only a single MAC exists for the shared bond0 interface and only a single IP can be assigned to bond0. When data needs to be sent from the appliance, only GB1 will send it using the bond0 MAC/IP. When traffic is sent to the bond0 MAC/IP, only GB1 will receive it, since only GB1 is responding to ARP requests using the bond0 MAC. If GB1 is disconnected, then GB2 assumes control of the bond0 MAC/IP for all data exchange. Failover-Routed In Failover-Routed mode, the appliance automatically switches to a secondary network interface in the event of a failure on the primary interface. When enabled, this feature allows the appliance to route network traffic to a secondary interface when a selected condition is met. After the administrator designates either the eth0 or eth1 network interface as the primary interface, one of the following conditions must be selected as the trigger that initiates the failover-routed feature: • Primary Interface Down • Unreachable Primary Default Gateway • Unreachable DSView • Unreachable IP Address To configure a network device: 1. From the sidebar, click Network Settings. 2. Enter the hostname (the hostname will be used for e-mail notifications as the sender address). 3. Use the drop-down list to select Normal, Failover or Failover-Routed for the mode. 4. Enter the primary and secondary DNS addresses in the appropriate fields. 5. Enter the domain name. 6. Use the drop-down lists to select the IPv4 and IPv6 default gateways, if Normal or Failover is the selected mode. -or- If Failover-Routed is the selected mode: a. Click the drop-down list to select the IPV4 Primary Interface. b. Select the appropriate radio button option from the Failover-Routed IPv4 Trigger Mode list. 7. Click Apply. 5.3.2 Bridge Group Configuration An administrator can choose network interfaces to bridge together into a logical bridge group. This feature simplifies the creation, deletion and maintenance of bridged interfaces. You can bridge both physical and virtual interfaces, and bridging supports user-created interfaces as well as the pre-defined ones. A bridge group can be created for each virtual and physical interface defined on the appliance. When a bridge group is created, it will be assigned a Layer 3 IPv4/IPv6 address. When interfaces are added to a bridge group, a prompt will be displayed, indicating that all IP addresses assigned to the interfaces will be lost and communication with devices accessible through the ports within the bridge group will occur via the bridge group's IP address. Appliance interfaces placed into a bridge group will not support DHCP services to prevent conflict with other DHCP services on the network. The appliance will also not support UMIQ modules connected to bridged interfaces. The appliance is not intended to be a general purpose ethernet bridge. The port bridging feature is intended to make devices, which are physically connected to private interface ports, accessible via the public network infrastructure. In order to prevent a switching loop when multiple bridged interfaces are accidentally connected to the same network switch, the Spanning Tree Protocol (STP) feature is enabled by default for all bridge groups. If the appliance is connected to a network switch with an active Bridge Protocol Data Unit (BPDU) Guard, the STP feature must be disabled for the bridge group. NOTE: Disabling STP will cause the appliance to store and forward ethernet frames between the ports of the bridge group without any switching loop prevention. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 25

1. From the sidebar, click Network Settings. 2. Under the Bridge Group Configuration heading, click Add. -or- Click on an existing bridge group to edit it. 3. Enter a name for the bridge group. 4. Ensure STP is enabled. 5. Use the drop-down menu to enable the Bridge State. 6. From the list of available bridge interfaces, select the interfaces you want to add to the group and click the right arrow. 7. Under the IPv4 heading, enter the Maximum Transmission Unit (MTU) and use the drop-down menu to select either DHCP or Static routing. If using Static, enter the Address, Broadcast and Gateway. -or- Under the IPv6 heading, enter either DHCP or Static routing. If using Static, enter the Address and Gateway. Click Apply. 8. Back on the main Network Settings page, change the IPv4/IPv6 default gateway to the name you assigned to the bridge group. Click Apply. To delete a bridge group configuration: 1. From the sidebar, click Network Settings. 2. Under the Bridge Group Configuration heading, check the box next to the name of the bridge group you want to delete, then click Delete. 5.3.3 Hosts An administrator can configure a table of host names, IP addresses and host aliases for the local network. To add a host: 1. From the sidebar, select Network - Hosts. 2. Click Add to add a new host. 3. Enter the IP address, hostname and alias of the host you want to add, then click Apply. To delete a host: 1. From the sidebar, select Network - Hosts. 2. Click on the name of the hostname you want to delete, then click Delete. 5.3.4 Routes Proper routing will ensure that traffic flows from clients to the appliance and back. The routing table in the appliance shows the networks that are connected as well as networks the appliance has been told about or have been learned dynamically. If traffic is destined for a remote network but the appliance cannot find a specific route matching the destination network, it will revert to sending the traffic to its default gateway. This is why some traffic does not get sent or received as expected. NOTE: The appliance is specially designed for managing and providing access to device management consoles. It is not supported as a general purpose router, switch or packet filter. Static routes to specific network destinations can improve the accuracy of the decisions made by the appliance about which interface to use when sending traffic. NOTE: It is important to ensure there is never a duplicated network address assigned to more than one interface within the appliance. It is also important to change the default private network addresses within the appliance if they conflict with networks already present within your infrastructure. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 26

1. From the sidebar, select Network Settings - Routes. Any existing static routes are listed with their Destination IP/Mask, Gateway, Interface and Metric values shown. 2. Enter the destination IP, gateway and netmask values in the appropriate fields, then use the drop-down menu to select the device interface. 3. Click Add. To delete a static route: 1. From the sidebar, select Network Settings- Routes. 2. Click on the name of the static route you want to delete, then click Delete. 5.3.5 OSPF and BGP The appliance supports Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) routing standards and their associated configurations. An administrator can add, edit and delete OSPF and BGP networks. OSPF In order to use OSPF, an administrator must first configure the appliance ID, interfaces and networks settings. By default, OSPF speaks to all interfaces on the appliance. An administrator cannot add an interface but may change the status of an existing interface. An administrator is able to add a network for the appliance to give and receive information from other OSPF nodes within the network. When adding a network, it must be unique to the appliance. The network value is in CIDR format of an IP address/netmask, for example: 10.12.1.0/24. To configure OSPF: 1. From the sidebar, click Network Settings - OSPF. 2. Check the box to enable OSPF. NOTE: When OSPF is enabled or disabled, an alert will be sent to the alert manager. 3. Enter the appliance ID, then click Apply. The appliance ID should be an IP address, but it can be any arbitrary 32-bit number. The appliance ID must be unique within the entire OSPF domain. 4. Use the drop-down menus to set the Interfaces to either Active or Passive. OSPF will not speak to any interface set to Passive. 5. To add a network, enter the address for the network and its area, then click Add. 6. To edit an existing network, check the box next to the network under the Modify an OSPF Network heading. When finished, click Apply. 7. To delete a network, check the box next to the network, then click Delete. BGP BGP is one of the key protocols used to achieve internet connection redundancy. BGP appliances use TCP protocol on port 179 to communicate with each other. BGP sends only incremental updates containing the routing entries that have changed since the last update. BGP peers are established by manual configuration between appliances to create a TCP session on port 179. Every 30 seconds, a BGP speaker will send keep-alive messages to maintain the connection. Each BGP appliance maintains a separate TCP session with other BGP appliances to which it is connected. An Autonomous System (AS) is a group of IT networks run by one or more network operators with a single, clearly defined routing policy. When exchanging routing information, each AS is identified by a unique number. The 16-bit number range is from 0 to 65535. From 64512 to 65535 is reserved for private use. Exterior routing protocols such as BGP are used to exchange routing information between Autonomous Systems. An AS will normally use some interior gateway protocol to exchange routing information on its internal networks. The network value is in CIDR format of an IP address/netmask, for example: 10.12.1.0/24. The configured network will be announced to all its neighbors. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 27

1. From the sidebar, click Network Settings - BGP. 2. Check the box to enable BGP. NOTE: When BGP is enabled or disabled, an alert will be sent to the alert manager. 3. Enter the AS number and appliance ID, then click Apply. The appliance ID should be an IP address, but it can be any arbitrary 32-bit number. 4. To add a network, enter the address for the network then click Add. 5. To edit an existing network, check the box next to the network under the Modify a BGP network heading. When finished, click Apply. 6. To delete a network, check the box next to the network, then click Delete. 7. To add a neighbor (peer), enter its IP address and remote-AS number then click Add. NOTE: The default AS number is 64512, which is a private AS number. You will need to modify it when using BGP to make sure it's unique in the network. 8. To edit an existing neighbor, check the box next to the neighbor under the Modify a BGP neighbor heading. When finished, click Apply. 9. To delete a neighbor, check the box next to the neighbor, then click Delete. 5.3.6 Network Share The appliance supports the ability to upgrade multiple SPs through network share. An administrator can configure the network share by clicking Network Settings - Network Share from the Administration sidebar. To configure a Samba client for network share: 1. From the sidebar of the Administration tab, click Network Settings - Network Share. 2. Under the Settings tab, in the External Samba Server field, enter the IP address or hostname of the Samba server. 3. In the Share Path field, enter the subdirectory that represents the network share. NOTE: The field may be left empty to represent the root directory. 4. In the Domain Name field, enter the name of the Windows domain name of the server. 5. Enter the username and password for the network share in the appropriate fields. To view the contents of the root directory of the network share, click the Contents tab. 5.4 Users Access to ports can be optionally restricted, based on authorizations that an administrator can assign to custom user groups. Groups can also be authorized to manage power while connected to devices. The appliance has three default users (admin, operator and user) and three pre-defined user roles (appliance administrator, power-user and user). 5.4.1 User role group A user role defines the view and what the user can do within the web UI and CLI, regarding appliance settings and administration. USER ROLE DESCRIPTION User Target access only. Power- User View appliance information, reboot appliance, disconnect user sessions, target access, target power operations and view data logs. Appliance- All user and administrator functions including upgrading the Table 5.1 User Roles Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 28

The Appliance-Admin role is the only one with shell access. 5.4.2 Users group A user account must be defined for each user on the appliance or on an authentication server. Only an admin can add and configure other user accounts. Each local user account is assigned to one or more of the user groups. CAUTION: Change the default passwords before you put the appliance into operation. 5.5 Password Policy The default username and password for the appliance is admin and admin. An administrator may configure global password rules to all user accounts. The maximum length of a password is 64 characters. When the password policy is increased from a lower level to a higher one, all local user accounts will be flagged to change the password at next login. In all cases, passwords will be checked to ensure they are not comprised of palindromes or repeated strings. SETTING DESCRIPTION None Passwords can be as short as one character and may contain any character. Passwords can be immediately re-used. Password expiration is set to never by default. Weak Passwords must contain at least four characters, at least one of which must be a number. When a user changes a password, it must be different from the old password. Passwords are set to expire after one year, by default. Medium Passwords must contain at least eight characters, including one number and one capital letter. When a user changes a password, it must be different from the old password. Passwords are set to expire after 90 days, by default. Strong Passwords must contain at least 16 characters, including one special character, one number and one capital letter. When a user changes a password, it must be different from the old password. Passwords are set to expire after 30 days, by default. Table 5.2 Password Policy Settings 5.6 Preemption Levels The preemption level of users determines whether they may interrupt or disconnect another user’s KVM session with a target device. Administrators and user administrators may specify the preemption level for user accounts or user-defined user groups. By default, the preemption level active for the user is the highest assigned value of all of the user groups to which the user belongs. Preemption levels range from 1-6, with 6 being the highest level. For example, a user or a user group with a preemption level of 6 may preempt other level 6 users or user groups, as well as those with a level 1, 2, 3, 4 or 5 setting. PREEMPTION LEVEL DESCRIPTION 6 The default level for the admin account. Only available to admins. 5 The default level for the factory operator account. Only available to operators and administrators. Table 5.4 User and User Group Preemption Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 29

serial console appliance. 3 The default level for the Avocent® Universal Management Gateway Appliance . 2 The default level for the user administrator user group. 1 Default for new users. The default for the Factory user account. The preemption levels may be used in the following ways: • User preemption level - This is the preemption level assigned to a user by an administrator. If this value is larger than the highest preemption level of the user group to which the user belongs, the value will be used as the effective user preemption level. • Group preemption level - This is the preemption level assigned to user groups to which the user belongs. If the user is assigned to multiple user groups with different preemption levels, this will be the preemption level of the user group with the highest level. For example, if a user belongs to the appliance administrators (level 6) and users (level 1) user groups, this value will be defined as 6. If this value is larger than the highest preemption level of the user, the value will be used as the effective user preemption level. An appliance administrator or power user may also specify a local user interface preemption level that is applied to users accessing target devices through the local interface. 5.6.1 Adding a user To add or modify a user: 1.

Click Apply. 5.6.5 Groups User groups are given access and authorizations either by default or as assigned by an administrator. Administrators can alter the permissions and access rights of users belonging to the Power User or User groups or create additional groups with custom permissions and access rights. Administrators can add, delete or modify permissions and access rights for users from any group at any time. For example, if an administrator configures the appliance to restrict user access to a target, the administrator can assign users to groups that are authorized for specific target access. The administrator can also authorize groups for power management and data buffer management. This document and the software refer to users whose accounts are configured on remote authentication servers as remote users. Remote users do not need local accounts. LDAP authentication services allow group configuration. If a remote user is configured as a member of a remote group, the authentication server provides the group name to the appliance when it authenticates the user. A local group by the same name must also be configured on the appliance. If an authentication server authenticates a remote user but does not return a group, then the remote user is, by default, assigned to the user group. Managing user groups Administrators can create custom user groups that contain any users. Permissions and access for custom user groups will be determined by the top-level user group permissions. To add or modify a user group: 1. From the sidebar, click Users - Groups. 2. Click Add to create a new user group. The Create User Group screen appears. Enter the new user group name and use the drop-down menu to define the user group role (User, Power-User or Admin). Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 32

From this screen you can rename or delete a target, or view a target's status. To rename a target: 1. Click and highlight the target name you wish to change. 2. Overwrite the existing name with the desired name. 3. Check the box next to the new target name and click the Rename button at the top of the table. To delete a target: 1. Check the box next to the target you wish to delete. 2. Click the Delete button at the top of the table. 5.7.1 Licenses Under the licenses heading is a summary of the total SP licenses and the number of remaining licenses. The number of license available vary by model. If there are insufficient licenses to discover or add targets, you will receive a low-license warning. Targets in excess of the available licenses will be ignored. 5.7.2 Port configuration An autosense port can operate in either serial or network mode. Ports configured for network mode will be assigned to a virtual interface that provides the IP communication with connected devices. The appliance contains three preconfigured virtual interfaces named priv, kvm and spm. They have unique names and IP addresses but all share a common MAC address. By default, only the priv virtual interface is enabled and all ports in network mode are assigned to it. There is a single active DHCP range associated with the IP assigned to priv. An administrator can create additional virtual interfaces to further separate or group IP devices by various types. For example, Dell® SPs could be grouped within a single subnet behind a virtual interface named Dell® and IBM® SPs could be grouped within a different subnet behind a virtual interface named IBM®. Devices that are physically connected to the appliance are secured and prevented from intercommunication with other devices regardless of their virtual interface assignment. This prevents an operator who is authorized to access one device from gaining unauthorized access to the other connected devices. The appliance can support up to 64 SP/PDU targets per each of its 40 ports. Multiple SP/PDU targets per port can be achieved by connecting to a blade chassis or by connecting to an unmanaged layer 2 switch which has targets connected. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 36

Putting a layer 2 switch in between a UMIQ module and the appliance can damage or destroy the switch.

NOTE: IP addresses in CIDR format will utilize a standard decimal notation address (192.168.0.1) with the subnet mask represented by the number of network bits in the mask. (255.0.0.0 = /8, 255.255.0.0 = /16, 255.255.255.0 = /24). Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 37

1. Click Targets - Port Configuration - Network Settings. 2. Under the Custom Interfaces heading, enter the name for the private interface. 3. Enter the broadcast address. 4. Click Add. NOTE: If DHCP is desired, the IP address of the virtual interface should correspond to a dynamic range on the DHCP settings page. Newly created interfaces will not issue DHCP addresses until the DHCP service is restarted. To edit or delete a virtual interface: 1. Click Targets - Port Configuration - Network Settings. 2. Under the Modify a Virtual Interface heading, check the box next to the private interface you want to edit. 3. Make your changes. -or- Click Delete to delete the interface. 4. Click Apply. NOTE: A user cannot enable an interface if an IP address is empty. DHCP Settings From the sidebar, click Targets - Port Configuration - DHCP Settings to view or change the default DHCP server settings. The appliance DHCP server is required to issue IP addresses to UMIQ adaptors and can be used to issue IP addresses to SPs. A dynamic range is required to issue DHCP addresses incrementally or based on MAC address reservations. The DHCP server can only operate on appliance private interface ports. To configure DHCP settings: 1. Click Targets - Port Configuration - DHCP Settings. 2. Check the box to enable or disable the DHCP server. NOTE: If using the DHCP relay option, new firewall rules will need to be created for the interface that will receive the DHCP request to permit FORWARD traffic to the external DHCP server host and back again. 3. DHCP leases are defined in days (default is 30). 4. Dynamic ranges can be added or deleted by clicking Add or Delete. Within each dynamic range, the gateway field defines the range association with a virtual interface. 5. DHCP reservations are created by clicking Add or Delete in the Assignment by MAC Address heading. The hostname is a name for the reservation. The MAC Address is the layer2 physical address of the target network card. The Fixed Address is the IP address to be issued. The lease bindings tell you which IP addresses have been dynamically assigned to targets. It displays the range, start and end times, MAC address, hostname, port number and target device type. The lease bindings can only be cleared by deleting the dynamic range they were issued from and restarting the DHCP server. Lease times are measured in days. NOTE: Only one range may operate on a private interface. Advanced settings Within the appliance shell, the /etc/dhcpd.conf file can be edited to add DHCP scope options, such as option 6 (DNS server) or option 15 (DOMAIN name). Discovery You can discover service processors, rack PDUs or terminal servers from a variety of IP ranges within routed access of the appliance. You can specify up to 20 IP address ranges either for automatic or manual discovery. Discovered devices are displayed in the SP Management list. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 38

pre-populated in the Default Users tab. The device must be a type supported by the appliance as listed in the firmware release notes. Whether performing a discovery, importing or manually adding a device, the appliance will always perform a capabilities discovery to determine the licensed feature set of each device in order to display session buttons or control capabilities appropriate for what the device will support. For example, an HP iLO without an advanced license does not support vKVM. When added to the appliance, the capability discovery will recognize the license in the iLO and will disable the vKVM session button. CAUTION: The appliance requires most SP types to have IPMI enabled in order to be discovered or managed. Some SPs will have IPMI disabled by default, for example, iDRAC7. If the SP is physically connected behind the appliance and cannot be discovered or added due to an IPMI problem, you may manually add the SP using the generic profile. Then launch an SP Access browser session to the SP and correct the IPMI problem. Then delete the generic SP and add it using the appropriate SP profile. Physical discovery The appliance has a DHCP service active by default running on the priv virtual interface. SPs physically connected to the appliance and configured as DHCP clients will be issued an IP and then queried for discovery. A DHCP scope is, by default, assigned only to the priv virtual interface and associated physical ports. The spm and kvm virtual interfaces do not have addresses assigned to them by default. To assign DHCP ranges to the spm and kvm virtual interfaces to discover and manage certain classes of devices independently, the virtual interface must first be assigned an IP. The priv virtual interface is by default: 192.168.10.1/24. To assign virtual interfaces IP addresses: 1. Browse to the Network Settings page located at Administration - Targets - Port Configuration - Network Settings. 2. Use the drop-down menu under state to enable the interface. 3. Enter the IP address/mask and broadcast address. 4. Click Apply. The IP address (CIDR format) is sometimes referred to as prefix notation for an IP/mask combo. The IP/mask information required is the number of bits occupying the network portion of a subnet mask when displayed in binary notation. The following table is an example. DECIMAL BINARY PREFIX/CIDR EXAMPLE 255.0.0.0 11111111.00000000.00000000.00000000 /8 10.1.2.3/8 255.255.0.0 11111111.11111111.00000000.00000000 /16 172.18.1.4/16 255.255.255.0 11111111.11111111.11111111.00000000 /24 192.168.1.10/24 255.255.255.252 11111111.11111111.11111111.11111100 /30 176.23.8.1/30 Table 5.8 CIDR Format Example After assigning the virtual interface IP addresses, new DHCP ranges can be created. It is important to ensure that the DHCP range is appropriate for the IP assigned to the virtual interface but that the range does not contain that IP (avoid potential for IP conflict). The virtual IP should be assigned as the gateway for the new range. To create dynamic DHCP ranges: 1. Browse to Targets - Port Configuration - DHCP Settings. 2. Under Dynamic Ranges, click Add. 3. Enter the Subnet address, the start and end range, the subnet mask and the gateway. 4. Click Apply. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 39

the appliance will be able to leverage the accounts list to find matching credentials. If the appliance is able to successfully log in, the SP will appear within the targets list. To add/edit credentials in the default users list: 1. Browse to Targets - SP Management - Default Users. 2. Click Add to add a new user. -or- Click the username to edit the user. 3. Add or edit the username and password. 4. Add or edit the description as desired. 5. Click Apply. Logical discovery The appliance supports creation of up to 20 discovery queues that can be leveraged to discover SPs on the network. The discovery ranges define a start-stop IPv4 address that the appliance will scan looking for SPs. The discovery can be run as Manual (run-once) or Automatic (runs according to defined minute interval). If the appliance can identify the SP type and log in using credentials from the default user list, the SPs will be added to the list of targets. If the appliance cannot identify or log in to the SP, nothing will be added and you will need to either manually add it or use the Import SP feature. To discover service processors: 1. In the navigation menu, click Targets - Discovery. 2. From the IP Ranges tab, click Add Range to open the Modify Search Range screen. 3. Enter the name for the search then enter the IP addresses for the range in the From and To fields. 4. Use the drop-down menu to either manually or automatically start the search. 5. If you want to automatically discover devices on a timed interval, you can enter an interval range from 10 minutes to 30 days. Enter the time interval in dd-hh-mm (days-hours-minutes) format. 6. Use the right and left arrows to select the discoverable targets classes to search. NOTE: Available target classes are Dell SPs, HP SPs, IBM SPs, other SPs, Rack PDUs and terminal servers. 7. Click Apply to begin the discovery process. NOTE: Rescanning the same IP range in an environment that is mostly static will consume appliance processing resources and increase network traffic unnecessarily. Automatic discovery is only recommended for dynamic environments that undergo frequent change. Default Users The appliance contains a list of default usernames and passwords that will be used when adding and discovering devices. You can add to or modify the credentials in this list. The description can be used to identify an account. You can also delete a default user by clicking the box next to it and clicking Delete. To add or modify a default user: 1. From the sidebar, click Targets - SP Management - Default Users. 2. Click Add to add a new user. -or- Click a hyperlinked username to modify that user. 3.

IPMI and discovery settings An administrator can automatically enable the Intelligent Platform Management Interface (IPMI) on the appliance during discovery or when manually adding an SP. Use the following instructions to enable IPMI and set your preferences when discovering target devices. To automatically enable IPMI and set discovery preferences: 1. From the sidebar of the Administration tab, click Targets - Discovery and then click the Settings tab. 2. Check the box to automatically enable IPMI on SPs during discovery or manual add. 3. Check the box to always update the default alias whenever a target is re-discovered. 4. Select either IP address or hostname as the default alias name preference. If using hostname, you can check the box to ensure the DNS server is not queried for SPs. NOTE: Querying the hostname may increase the discovery time. 5. Check the appropriate box to automatically manage discovered PDUs, SPs and Terminal Servers. NOTE: If you do not configure the appliance to automatically discover PDUs, SPs and Terminal Servers, these devices will appear, along with unsupported devices, under the Targets tab in the sidebar under Accessible Targets. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 41

NOTE: If this checkbox is disabled, unsupported devices will not be discovered. 7. Click Apply. To reset unmanaged targets: 1. From the sidebar of the Administration tab, click Targets - Discovery and then click the Settings tab. 2. Click Reset Unmanaged Targets to delete the list of discovered accessible targets and return unmanaged devices back to an undiscovered state. NOTE: Devices listed under Accessible Targets must be deleted before the devices can be rediscovered as a managed target. Hostname discovery By default, the appliance assigns an alias using the appliance mac address and the SP IP address. For example, an SP with an IP address of 10.207.16.99 discovered on an appliance with a mac address 00:e0:86:0b:dd:38 would be assigned a name of 0b-dd-38_10.207.16.99. However, if you enable hostname discovery, the appliance will detect the SP hostname at time of discovery and assign the hostname as the alias. To update an alias name to the currently assigned hostname: 1. After discovering an SP, from the sidebar of the Administration tab, click Targets - SP Management. 2. From the Service Processors tab, check the box next to the SP or SPs you want to update and click Refresh Hostname to query the hostname. If a hostname cannot be determined, the alias will not be changed. Discovery log The discovery log displays the results of SP add and SP discovery processes on the appliance. The log chronologically displays the status of the add/discovery steps and will automatically update as status changes occur. To view the discovery log, from the Administration tab, click Targets - Discovery, then click the Log tab. TYPE DESCRIPTION Filter Options Method Defines whether the SP was discovered, manually added or imported. Credential Defines whether default credentials were used or manually supplied. Status Defines whether the SP is being discovered, was successfully discovered or an error occurred during the discovery process. Comment Definitions Target Added The SP was successfully added. No ping response No SP is found. Not communicating An SP has been found but the appliance is unable to communicate with it.This is likely due to IPMI being disabled on the SP. See Discovery on page 38. Type/credentials not found The SP is not supported or valid credentials were not found from the Default Users list. Table 5.9 Discovery Log Definitions For a single page of the discovery log, an administrator can filter the results using the Method, Credential and Status drop- down menus. The columns can be sorted in ascending/descending order by clicking on the column header. The refresh button will reset to default the filter and sort options. To filter the discovery log: 1. From the sidebar, click Targets - Discovery, then click the Log tab. 2. Use the drop-down menus to filter by Method, Credential and/or Status. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 42

The entire discovery log can be purged by clicking Clear All. Clicking Refresh resets all the filtering parameters. Selecting Download Advanced Logs generates a zip file of the discovery log information for all searched IP addresses. To download the discovery log: 1. From the sidebar, click Targets - Discovery, then click the Log tab. 2. Click Download Advanced Logs, then click OK. 3. Click the zip file and extract the file. 5.7.3 SP management A service processor (SP) can be connected to any numbered target port on the back of the appliance. Service Processors that lack a dedicated interface are shared with NIC1 in what is called Side-Band. Side-Band SPs can only be communicated with logically by the appliance via your network. The SP will need to be assigned an IP that the appliance can communicate with. Many SPs can be configured to either use the dedicated interface or share (Side-Band) with NIC1. The appliance can communicate with the SP in either implementation via IP. When SPs are physically connected to the appliance, the IP of the SP is not accessible to your network. OEM tools will not be able to communicate with the SP unless the appliance is placed in Bridge mode. The SP manager prevents communication between its numbered target ports, but the appliance does not. The SP Management screen displays all Service Processors (SPs) connected to the appliance. From this screen you can add, delete and manage SP settings. An SP can be manually added to the appliance if the appliance has IP access to the SP and has a corresponding profile to support the SP type. The username/password must be provided in the Add SP Wizard. Common credentials can be pre-populated in the Default Users tab. The profile you choose needs to match the SP as closely as possible. SPs that use IPMI will use the KG (Hex format) and Cipher settings to implement a symmetric IPMI 2.0 encryption key to encrypt the UDP-based IPMI traffic. To ensure all of the SPs' capabilities are available to the appliance, make sure the SPs enable IPMI-over-LAN in their configuration. Because IPMI is sometimes customized, support for non-standard implementations will vary. NOTE: Appliance support for each SP is dependent upon SP firmware capabilities. See the appliance firmware release notes for a complete list of SP types and supported SP firmware versions. SPs and SP versions that are not listed as supported may have some level of support if manually added to the appliance using the IPMI_2.0 or generic SP profiles. The appliance firmware and release notes can be found at http://www.VertivCo.com. You can also add multiple SPs at once by creating a custom file containing the IP address, port, username, password and SP type of the SPs you want to add. Once SPs are added, their information will be displayed within the table on the SP Management page. NOTE: Users that do not have Administrator access will only see devices to which they have access. Generic service processors The appliance can provide access to a generic IP based management console on any device or to an unsupported SP. The device is manually added as an SP using the generic profile. NOTE: Credentials are not required to add a generic SP. The appliance will perform a capability discovery to find a management console listening on TCP port 22 (SSH), 23 (telnet), 80 (HTTP), 443 (HTTPS). After the generic SP has been added it will appear on the main Targets tab and the available session buttons will be activated to the appropriate capabilities discovered on the device.

For example, Filter 1, Filter 2, Filter 3. 4. Click Apply. User Info The appliance supports target interdiction for all recognized Service Processors (SP). This feature allows you to store and manage passwords for each SP target. Enable this security feature by manually or automatically creating a password that is stored within the appliance. The target interdiction feature operates in either User mode or Host mode. The User mode allows you to manually change the password for the Service Processor. In this mode, the user creates and confirms the password manually. For even more security, enable the Host mode, which allows the appliance to control the SP by creating and securely storing the password. When the SP is in Host mode, the password is shielded from all users and users can only access the SP via the appliance. As a fail safe, a rescue account can regain control of the SP if the appliance looses communication with the SP or generates an error while SP is in Host mode. An administrator must create a rescue account before using the target interdiction feature. The following processes help you set up a rescue account, enable the Host mode and regain control of the SP via the User mode. Figure 5.4 User Info tab To create a rescue account: 1.

The Avocent® Universal Management Gateway Appliance combines analog and digital technology to provide flexible, centralized control of data center servers and virtual media, and to facilitate the OA&M (operations, activation and maintenance) of remote branch offices where trained operators may be unavailable. KVM over IP gives you flexible target device management control and secure remote access from anywhere at anytime. The KVM over IP functionality of the appliance provides enterprise customers with the following features and options: • Keyboard, video and mouse (KVM) capabilites, configurable for analog (local) or digital (remote) connectivity • Enhanced video resolution support, up to 1600 x 1200 or 1680 x 1050 (wide-screen) native from target to remote NOTE: For a full list of supported resolutions, see Video Resolution on page 108. • Virtual media capability accessed through USB ports • Smart card capability UMIQ module An Avocent® UMIQ module is an adaptor that provides traditional VGA/USB based KVM over IP support to the appliance. The module digitizes an analog VGA signal and USB signals (keyboard, mouse, mass storage, CD/DVD, smartcard-CAC) and delivers them over IP. This enables an at the rack experience for remote users no matter where they choose to be.

to connect to the appliance via a CAT 5 cable. The v2 module has a second port which can be connected to a dedicated SP. 2 DC power plug. 3 VGA connector for video. 4 USB connector for keyboard and mouse. Table 5.12 UMIQ Module Descriptions The UMIQ module has an embedded Linux OS that boots when the UMIQ module has power. The UMIQ module requires full USB bus power in order to properly operate. The DC power plug is useful for servers that do not provide sufficient power, for devices that lack USB interfaces, or for provisioning stations where the IQ module would be moved quite regularly from one server to another. As long as the UMIQ module has power from USB or DC it is considered to be at full power and it can maintain the secure IP connection with the appliance and KVM sessions with users. If the UMIQ module loses power but is still connected to the appliance, the UMIQ module will request the appliance send standby power via the UTP cable to prevent the UMIQ module from going offline. The UMIQ module running on standby power cannot support KVM sessions, but it can maintain its connection to the appliance. The UMIQ-v2 module can maintain the bridge between its two ports ensuring that the SP is always accessible. The appliance will use the DC connector for all of its power needs and the USB plug will just be used for data exchange. The appliance draws 5v at 0.5a from either DC or USB. When connecting an autosense port to a UMIQ module a straight UTP cable should be used. The UMIQ-v1 module has a single RJ45 port intended to be connected to the appliance. The UMIQ-v2 module has two RJ45 ports, either one can be connected to the appliance and the other can be connected to a dedicated service processor port on the server. The cable length can be up to 100 meters long. WARNING! Never connect a network (switch/hub/firewall/router) between the appliance and a UMIQ module. The appliance sends electricity that will damage anything that is not a UMIQ module. LED PATTERN DESCRIPTION Power LED Constant ON Power LED is on when the UMIQ module is operating with USB power, in a normal operating state. Continuous single blinks During the upgrade, the UMIQ module will blink an LED at a rate of 2 Hz with a 50% duty cycle. Groups of two blinks The UMIQ module is using standby power provided via ethernet cable from the appliance. Groups of three blinks Insufficient power is provided. This may happen before the UMIQ module is enumerated by the USB host on the target server. Active LED Constant On Active LED illuminated when there is an active KVM session. Continuous single blinks (rapid) Used for identifying a UMIQ module, Enabled/Disabled within the appliance web UI. Continuous single blinks (slow) The Active LED periodically blinks to indicate that the UMIQ module has been associated with the appliance (i.e., it has been discovered by the appliance). Both LEDs Continuous single blinks (rapid and alternating with the Power LED) Alternating LED blinks at a fast rate indicate when a firmware upgrade has failed.

Normal is an interactive session that may be shared with other users. Exclusive is a private session that does not allow sharing by other users. • Type - Session type, which may be KVM, virtual media or serial. • Name - The name of the target. • User - User who initiated the session, which may be a user, a local port user or a user with a local user account. • Duration - Current length of the console session. • Client - IP address of the client computer connected to the session. • EID - Displays the unique electronic ID embedded in the module. To view or terminate active sessions: 1. Click Active Sessions. 2. Select the box(es) next to the session(s) you wish to terminate. Click Terminate. Default settings KVM default settings are global settings that will apply to new UMIQ modules. These settings have no effect on existing UMIQ modules. However, you can apply the default settings to existing UMIQ modules by performing a factory reset. General Under the General heading, you have the option to delete offline modules or automatically upgrade modules. By default, both settings are disabled. For more information see Upgrading UMIQ modules on page 55. You can also set the Session Connection Timeout from this heading. The appliance can actively establish one KVM session for a given client IP address. The appliance must wait for that session to be established or time out before it can try to establish another session. The Session Connection Timeout sets the maximum amount of time allowed to try to establish a KVM session before timing out, when another session is waiting to be connected. Under most circumstances, the default Normal is the preferred setting. Using Normal will ensure the system is responsive and will avoid Path Blocked warnings. The longer time-out settings can be used for special circumstances, such as in a system where the Network Address Translation (NAT) is used and multiple clients appear as a single IP address to the appliance. Sharing Under the Sharing heading, you can enable and select the level of sharing. Options include: Automatic, Exclusive and Stealth. • Automatic is a sharing option that will automatically allow another user to share a target session. The user establishing the new session is prompted to share while the existing user is not. • Exclusive is a private sharing option that does not allow sharing by other users. • Stealth is a sharing option that starts a Video Viewer window session, but you will only be able to view what occurs on the target without controlling the keyboard or mouse. The user who is currently active will not be notified that access is being shared and no request to authorize sharing will be made. If the user's preemption level is higher than or equal to yours, the stealth connection may not be permitted. When you attempt to connect to a session already in use by another user, a dialog box states the target is not available for viewing along with the name of the current user(s). At this point, you may request to share access to the target, preempt the user or use stealth mode, if it has been enabled. • Share a connection - When you are prompted to share a connection and you click Share with the other user. When sharing a target, all users may monitor and take control it if no other user is active. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 56

been enabled. If the user confirms, you will be given target access. • Preempt a user’s connection - When you are prompted to preempt the user’s session and you click Preempt the other user, the user requesting access to the target will be connected and existing user(s) will lose their connection to the target. The existing user(s) will be notified that their sessions have been preempted. To display a list of users sharing their port or channel, select View - Connected Users in the Video Viewer window. Users in stealth mode are excluded from this display. Encryption level In the Encryption Level area, specify an encryption level for the keyboard/mouse, video and virtual media: • 3DES - SSL Triple DES encryption • 128-Bit SSL - 128-bit encryption which used an ARCFOUR (RC4®) SSL cipher • AES - AES encryption At least one encryption level must be specified for the keyboard and mouse. When you specify more than one SSL encryption type, the appliance negotiates the strongest algorithm that is supported by both sides. The strongest algorithm is AES, followed by 128 bit, 3DES and DES. Session settings Under the Session Settings heading you can configure the Input Control Timeout, enable and configure the session timeout, set the keyboard language, set the EDID (video) resolution and enable video noise control. NOTE: If a user connects to a target with a higher screen resolution than the local computer, the Video Viewer window will display a portion of the target screen, with scroll bars for viewing the remainder of the screen. The user may view the entire screen by adjusting the resolution on the target, the local computer or both. Session preemption Under the Session Preemption heading, you can enable preemption and set the time-out. Session Preemption Control specifies whether the user will be notified before the KVM session is preempted. If Session Preemption Control is enabled, the Session Preemption Timeout specifies the number of seconds to wait, after notifying a user the KVM, to preempt the session. For more information on preemption, see Preemption Levels on page 29. Virtual media Under the Virtual Media heading you can enable virtual media, lock to KVM session, allow reserved sessions and select the virtual media access mode. • The locking option specifies whether a virtual media session is locked to the KVM session on the target. When locking is enabled (default) and the KVM session is closed, the virtual media session will also be closed. When locking is disabled and the KVM session is closed, the virtual media session will remain active. • Allow reserved sessions ensures that a virtual media connection can only be accessed with your username and that no other user can create a KVM connection to that target. When the associated KVM session is disconnected, the virtual media session may be disconnected according to the Locked setting in the Virtual Media dialog box. • The virtual media access mode allows you to set the access mode for mapped drives to read-only or read- write. When the access mode is read-only, the user will not be able to write data to the mapped drive on the client server. When the access mode is read-write, the user will be able to read and write data from/to the mapped drive. If the mapped drive is read-only by design (for example, a CD-ROM drive, DVD-ROM drive or ISO images), the configured read-write access mode will be ignored. Setting the read-only mode can be helpful when a read-write drive such as a mass storage device or a USB removable media is mapped, and you wish to prevent the user from writing data to it. You can have one DVD drive and one mass storage device mapped concurrently. A CD drive, DVD drive, or ISO disk image file is mapped as a virtual CD/DVD drive.

The firewall and NAT feature enables an administrator to configure the rules governing traffic filtering, IP forwarding and address translation within the appliance. NOTE: The appliance is specially designed for managing and providing access to device management consoles. It is not supported as a general purpose router, switch or packet filter. The firewall and NAT features are built from a series of named definitions for networks, hosts, interfaces and services. Before you can configure the firewall and NAT policies, you must define the objects that will be used within the policy rules. It is best to start by defining the interfaces, then defining the networks that will be referenced by your policy rules before finally defining the hosts and services. Each of these are described in the next sections. The appliance will already have knowledge of various hosts, networks and interfaces; these objects will be created at the time they are defined or discovered by the appliance. For example, upon connecting a UMIQ module to the appliance, a host definition will be created matching the name assigned to the UMIQ module target. 6.5.1 Interfaces By default, all physical and virtual interfaces defined within the appliance will be listed on the Interfaces tab. You can access the Interfaces tab by clicking Firewall and NAT from the sidebar. New virtual interfaces can be made for use with private ports by clicking Administration - Targets - Port Configuration - Network Settings. For more information on creating an interface, see Port configuration on page 36. Figure 6.3 Interfaces Tab Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 73

NAT and firewall rules. Interfaces designated as Inside are private and interfaces designated as Outside are public. Be sure to designate at least one interface as Outside and one interface as Inside before trying to reference those interfaces within a NAT or firewall rule. When network mode changes or interface name changes occur, this table must be updated to ensure the proper interface is designated as Inside or Outside. Also ensure that IP addresses are correctly resolved in the tables at the bottom of the screen. If IP addresses are not correct, move them from the included list to the available list and back again to refresh the data within the table. To move an interface: 1. From the sidebar, click Firewall and NAT, then click the Interfaces tab. 2. Under the Outside i/f (Public) or the Inside i/f (Private) heading, click an interface you want to move from the Available field, then click the Right Arrow to move it to the Include field. 3. Click the Left Arrow to move the interface back to the Available field, if desired. 4. Repeat as desired for each interface under either the Outside or Inside headings. 5. Click Apply. To create IP aliases for 1-to-1 NAT: 1. From the appliance's Linux shell, type cd, then type /usr/bin/fwnatdirectory. 2. The fwnat-alias.sh script can be used to create IP aliases on the eth0/eth1/bond0/ interfaces. NOTE: Created IP aliases will appear on the Interfaces tab within the firewall. Syntax for the script is: ./fwnat-alias [-h] -c -i -n -a [-b ] [-m [*]] For example: ./fwnat-alias.sh -c add -i eth0 -n drac7 -a 192.168.200.195/24 -b 192.168.200.255 COMMAND DESCRIPTION -h Displays the command syntax -c Command to add, delete or modify an IP alias interface -i Alias for eth0 | eth1 | bond0 | bridge group -n Name of the alias up to 8 characters -a IP address in CIDR format -b Broadcast address -m Modified IP address in CIDR format with an '*' preceding the modified broadcast address Table 6.3 Script Syntax Commands Descriptions 6.5.2 Defined networks A network definition denotes a range of IPs through the CIDR formatted IP address. The subnet address/ID is the appropriate value for the IP address field combined with the subnet mask in prefix notation. Defining a network and associating it with an interface is an efficient way of using a single NAT or firewall rule to apply to any and all host IPs residing within an IP range. NOTE: Creation of network definitions is useful for grouping hosts within a range of IPs but is not required for all types of NAT and firewall rules. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 74

192.168.0.0 network. Representing a subnet mask in prefix notation is an efficient way of designating which part of the network address is the subnet ID and which part represents all possible hosts within the subnet. The best way to designate an IP range of 192.168.0.1-254 within a network definition on the appliance would be using the CIDR formatted address of 192.168.0.0/24. This process effectively assigns a name to a range of IPs or an entire network. The NAT and firewall rules rely on definition names exclusively. Figure 6.4 Networks Tab To add a network definition: 1. From the sidebar, click Firewall and NAT, then click the Networks tab. 2. In the Name field, enter a name for the network definition. 3. In the Interface Name field, enter the name of the interface with an IP from, or that has access to, the network being defined. The name must match one of the virtual or physical interfaces listed on the Interfaces tab. NOTE: The network and interface names each must be unique names between 3 and 40 alphanumeric characters. 4. In the IP Address field, enter a valid subnet ID for the network in CIDR format. 5. Click Apply. To modify or delete a defined network: 1. From the sidebar, click Firewall and NAT, then click the Networks tab. 2. Under the Defined Networks heading, check the box next to the network you wish to modify or delete. 3. Make your changes and click Apply. -or- Click Delete to delete the defined network. 6.5.3 Hosts Host definitions can be used in NAT and firewall rules for situations when an individual IP/host needs to be referenced separately than other hosts that would be affiliated with a network definition, or when multiple hosts need to be referenced uniquely with their own NAT or firewall rules. This process is effectively assigning a name to an IP address, and then using that name within the NAT and firewall rules. By default, the lists of hosts will be populated by SPs or UMIQ modules that have been connected to or discovered by the appliance. You can create new host entries to represent any IP regardless of the device. NOTE: Creation of hosts is useful for individual IP differentiation but not required for all types of NAT and firewall rules. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 75

To add a host: 1. From the sidebar, select Network - Hosts. 2. Click Add to add a new host. 3. Enter a name to represent the host, an IPv4 Address and the physical or virtual interface which can communicate with this host. Then click Apply. The new host definition will appear in the User Defined Hosts table. NOTE: The network interface must be one listed on the Interfaces tab. To delete a host: 1. From the sidebar, select Firewall and NAT - Hosts. 2. Click on the name of the host you want to delete, then click Delete. 6.5.4 Services Service definitions represent programs and network traffic by their TCP/UDP port number or port range. Service definitions are essential for network address translation of ports (PAT) where a single outside IP and unique ports are used to represent unique inside IP/ports. For example, if two unsupported rack PDUs were connected to private appliance ports, had private/inside IP addresses assigned to them and each had a web management console, then two NAT rules could allow outside administrators to access the rack PDU web management interfaces. Each NAT rule would use a unique service definition to represent the TCP port of the rack PDU web management interfaces on the public/outside IP of the appliance. For example, a service definition of 8080 would translate to 80 for the first rack PDU and 8081 would translate to 80 for the second rack PDU. The IP protocol supports 65,535 ports and the Internet Assigned Numbers Authority (IANA) has a registry of common/well- known TCP and UDP ports that represent various programs and services. This registry should be consulted to determine which ports are used by the applications or traffic for which you want to create NAT and firewall rules. Some applications do not register all of their ports with IANA and will typically include port usage lists with their product documentation. By default, the appliance has several well-known ports/port ranges defined as system services. Many of these services are included in the default appliance firewall policy in order to support the various features provided by the appliance.

rules. Figure 6.6 Services Tab To create a service definition: 1. From the sidebar, click Firewall and NAT, then click the Services tab. 2. In the Service Name field, enter a name to be used for the service. NOTE: A service name can be between 3-40 alphanumeric characters. 3. In the Service Address field, enter a valid subnet ID for the service in CIDR format. For example, 192.168.10.0/24. 4. Enter the starting and ending ports for the IP protocol. NOTE: Valid entries are from 0-65,535. 5. Click Apply. The new service definition will be displayed in the user-defined service definition table. To modify or delete a user-defined service definition: 1. From the sidebar, click Firewall - NAT, then click the Services tab. 2. In the User Defined Services table, check the box next to the service you want to modify or delete. 3. Make your changes and click Apply. -or- Click Delete to delete the service definition. 6.5.5 Policy An administrator can control the flow of IP traffic in, out and through the appliance with a NAT and/or firewall policy. An administrator can create policies that will allow an external host or server to communicate directly with IP devices (hosts) that are securely connected to the private ports of the appliance. A NAT or forward policy will allow traffic to bypass Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 77

only be implemented for select few situations. For example, an SP management tool (HP SIM) residing on the production network could be allowed to directly communicate with SPs (iLO) connected to the private ports of the appliance for the purpose of monitoring, configuration and firmware updates. But user sessions would not be permitted to bypass the appliance's securities and SP interaction would be governed by appliance-based permissions. This could be achieved through a simple NAT or IP forward policy rule allowing the management tool access to the SP. In addition, a firewall filter rule would prevent users from exploiting the NAT/forward rule used by the management tool. The following criteria should be used to make the determination between a NAT rule or an IP forward rule for providing bypass access to private hosts. An IP forward rule requires that the private IP network/subnet is unique with regard to other production networks and even other appliance private networks. If two appliances have the exact same IP network associated with their private ports/hosts, an external host would be unable to properly make a routing decision between the appliances when trying to send traffic to a private host behind one of them. The benefit of a NAT rule is that the same IP network/subnet can be repeated for private ports/hosts on multiple appliances without the same routing conflict. The appliance supports two forms of NAT: 1-to-1 NAT (IP masquerading) and port address translation (PAT/NAT overload). For successful end-to-end communication leveraging an IP forward policy rule, the private host must treat the nearest appliance IP as its gateway and all external hosts must have routes (static or dynamic) that reference the private network/subnet and nearest appliance IP. NOTE: In this context, the nearest IP is the one belonging to the same network or the closest routable IP on a different network. Network configuration changes made to eth0, eth1, bond0, br0, priv, kvm, spm, and any other bridge groups and virtual private interfaces could affect the applicability of NAT and firewall rules. All firewall rules that reference interface names or addresses that were replaced during the network configuration change should be edited within the NAT and/or firewall rules to ensure proper network communication. For example, eth0/eth1 must be replaced with br0 or bond0 where applicable. NAT flow Traffic entering an interface (incoming) is translated according to a NAT rule before any filtering rules and before any routing decisions. Traffic exiting an interface (outgoing) is translated according to a NAT rule after filter rules and routing decisions have been made. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 78

ITEM DESCRIPTION 1 Outside. 2 Inside. 3 Incoming NAT on an inside interface. 4 Incoming NAT on an outside interface. 5 Outgoing NAT on an inside interface. 6 Outgoing NAT on an outside interface. Table 6.4 NAT Flow Table Descriptions Firewall flow Traffic entering the appliance (input) is subject to filter rules after it has passed through NAT rules and routing decisions. Traffic exiting the appliance (output) is subject to filter rules before routing decisions are made and NAT rules perform any translation.

ITEM DESCRIPTION 1 Outside. 2 Inside. 3 Input filter on an inside interface. 4 Input filter on an outside interface. 5 Output filter on an inside interface. 6 Output filter on an outside interface. Table 6.5 Firewall Flow Table Descriptions Firewall and NAT flow Traffic flowing through the appliance which is expected to be both translated and filtered will require both NAT and firewall rules designed to match the traffic patterns appropriately. Translation happens before filtering when traffic is entering the appliance and filtering happens before translation when traffic is exiting the appliance. For example, if input traffic passes through an incoming NAT rule, which has translated the destination address, then the only way for the filter rule to match a destination address is to have the filter rule match the pattern of the translated destination address and not the original destination address of the traffic. This is because the address was translated before it could be filtered. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 80

The wizard follows a simple step-by-step process that, at its completion, assigns both managed and currently unmanaged SPs a public external IP address in order to mask a private internal IP address. A time-saving component of this process incorporates the discovery of unmanaged SPs while also assigning the parameters of a NAT policy rule without leaving the wizard. After the unmanaged SP is added to the appliance, the wizard guides an administrator through configuring the target with an external IP address. Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 83

and adding it as a managed SP. For both SP types, the wizard then requests an SP alias, an external CIDR IP address (you can request this information from your network administrator), an external broadcast IP address and an external interface to be used for the selected SP. The final page of the wizard displays all the information as a final review before you create the NAT policy for the SP. NOTE: The 1-to1 NAT wizard is solely for targets physically connected to ports 1-40 on the back of the appliance.

Table 7.3 SP Access Session Types When a user initiates an SP Access session, the appliance will open a small TCP port range to facilitate communication between the client and the SP. The client PC will open a pop-up browser window and will connect to the IP of the appliance using one of the ports allocated for the session. If the session type being launched is a SP Access Browser session, the appliance will FWD the traffic from the client pop-up window to the Service Processor and the user will be presented with the login prompt for the SP browser UI. If the session being launched is an SP Access Browser (auto login) session, the appliance will utilize the stored service credentials and will log into the browser UI of the SP before forwarding the client browser to the signed-in UI session of the SP. If the session type being launched is an SP Access vKVM/vMedia session, the appliance will follow all of the same steps included with the SP Access Browser (auto login) session with the addition of launching the Java vKVM viewer of the SP and passing the session back to the client PC. To start a session, click a button for the session type you want. If a user doesn't have permission to launch a particular session type, or if the SP does not support the session type, then the corresponding button for that session type is grayed out. There are two ways to access the Sessions page. From the Targets tab, you can click Appliance, then click the SP Session link under Remote Access.

consumption information. NOTE: Check the appliance firmware release notes to determine if your SP type supports this feature. Power capping Power capping is a process of reducing or limiting the power consumption allotted to a server. Implementation of a power cap will vary from server to server and typically relies on assigning various processor "P" states or processor clocking limits. Under the Power Capping heading, you can view power information, including status, thresholds, correction time and sampling period. Fields that aren't supported by the SP/server will be grayed out. NOTE: The default values are dependent on the SP type. If supported by the SP/server, you can enable power capping and configure thresholds for the SP/server by clicking Configure. NOTE: Before enabling power capping, consider the possible effect a lower clock rate will have on the applications hosted by the server. Power capping can be enabled or disabled and assigned a power threshold watt value. The correction time is the number of milliseconds the SP/server will wait before applying a corrective "P" state or clock rate to reduce power consumption below the threshold. The sampling period is how often in seconds the SP/server will query for current power consumption. The exception action is the action the SP/server will take when a threshold is exceeded, and the options will vary from server to server. 7.1.6 Sensors Click on the Sensors tab to view the sensor information for the target device. Click Refresh to refresh the sensors information. 7.1.7 Logs Click the Logs tab to download the SOL data buffering log or to clear all data log history.

selected, present a pop-up window that must be refreshed in order to receive the most current information. The Alert Destination button also presents a pop-up window. This window allows you to assign the IP address, destination selector and channel for the Intel® Node Manager to send alerts. It also indicates if the receiver is registered. The Intel Node Manager is supported by the following Service Processors: • Dell® iDRAC8 • FSC iRMC S4 • Lenovo® IMM2 • Dell® iDRAC7 • Dell® DCS • Cisco® USC-C220 7.2 UMIQ Modules Available UMIQ modules can be viewed under the Targets tab. From the sidebar, click on a UMIQ module to view its settings. Click Connect to open a KVM session with the selected UMIQ module. To view available UMIQ modules: 1. From the sidebar, click UMIQ and then click on a target to view its status and the power status. 2. Click Connect to open a KVM session with the target. 7.3 KVM Session Optimization The UMIQ module performs analog-to-digital video conversion, and the session quality will be subject to cleanliness of the video signal coming from the server. A poor quality session will exhibit blocky video and extremely slow mouse response. To improve session performance: 1. In the KVM viewer, click Tools - Automatic Video Adjustment to calibrate the A/D converter to the video signal coming from the server video card. 2. To identify a KVM session that is slow due to unclean video signals, click Tools - Manual Video Adjustment. A clean video signal will create 0 Pkts/Sec. on the performance monitor when there is not any activity on the target server. NOTE: Adjusting the screen resolution and screen refresh rate can have a significant effect on the cleanliness of the video signal and the speed of the resulting KVM session. For best results, try different combinations of these two settings followed by an auto video adjustment to improve the session speed. The amount of video input plays a big role in the speed of KVM sessions. Lower screen resolutions will be faster than higher screen resolutions. Decreasing the color depth and the screen scaling will also decrease the amount of KVM session data being transported and will increase session speed. If the above optimization options are ineffective at improving session speeds the Video Noise Control setting can be enabled, which will increase session speed by ignoring small video changes. The only negative to this setting is that it can increase the appearance of video “blocks”. Also take note of the other settings that can be configured for KVM targets globally or individually. The following information is an example of what is possible but not guaranteed since every target and every network will be different. You will also note that some of the metrics are not entirely analogous (that is, FPS vs. Pkts/Sec.) Also, the bandwidth usage does not reflect the quality/fluidity of the session (the KVM session was much smoother and better than the vKVM). Appliance KVM session in a 100 Mbps LAN environment: • KVM window resolution 1280x1024 @70 Hz (Windows Server) • Zero screen movement = 0 pkts/sec (avg. 0.7 Kbps download | 0.5 Kbps upload) • Continuous mouse circles movement on screen = 35 pkts/sec (avg. 216 Kbps download | 247 Kbps upload) Vertiv | Avocent®Universal Management Gateway Appliance Installer/User Guide | 89
