System Management Features

Multiple Management Options You can use any of the following methods to manage the switch: • Use a web browser to access the Dell OpenManage Switch Administrator interface. The switch contains an embedded Web server that serves HTML pages. • Use a telnet client, SSH client, or a direct console connection to access the CLI. The CLI syntax and semantics conform as much as possible to common industry practice. • Use a network management system (NMS) to manage and monitor the system through SNMP. The switch supports SNMP v1/v2c/v3 over the UDP/IP transport protocol. Nearly all switch features support a preconfiguration capability, even when the feature is not enabled or the required hardware is not present. Preconfigured capabilities become active only when enabled (typically via an admin mode control) or when the required hardware is present (or both). For example, a port can be preconfigured with both trunk and access mode information. The trunk mode information is applied only when the port is placed into trunk mode and the access mode information is only applied when the port is placed into access mode. Likewise, OSPF routing can be configured in the switch without being enabled on any port. This capability is present in all of the management options. System Time Management You can configure the switch to obtain the system time and date through a remote Simple Network Time Protocol (SNTP) server, or you can set the time and date locally on the switch. You can also configure the time zone and information about time shifts that might occur during summer months. If you use SNTP to obtain the time, you can require communications between the switch and the SNTP server to be encrypted. For information about configuring system time settings, see "Managing General System Settings" on page 239.

The switch maintains in-memory log messages as well as persistent logs. You

can also configure remote logging so that the switch sends log messages to a remote log server. You can also configure the switch to send log messages to a configured SMTP server. This allows you to receive the log message in an e- mail account of your choice. Switch auditing messages, CLI command logging, Web logging, and SNMP logging can be enabled or disabled. For information about configuring system logging, see "Monitoring and Logging System Information" on page 205.

Integrated DHCP Server

PowerConnect 8000/8100-series switches include an integrated DHCP server that can deliver host-specific configuration information to hosts on the network. The switch DHCP server allows you to configure IP address pools (scopes), and when a host’s DHCP client requests an address, the switch DHCP server automatically assigns the host an address from the pool. For information about configuring the DHCP server settings, see "Configuring DHCP Server Settings" on page 871. Management of Basic Network Information The DHCP client on the switch allows the switch to acquire information such as the IP address and default gateway from a network DHCP server. You can also disable the DHCP client and configure static network information. Other configurable network information includes a Domain Name Server (DNS), hostname to IP address mapping, and a default domain name. If the switch detects an IP address conflict on the management interface, it generates a trap and sends a log message. For information about configuring basic network information, see "Setting the IP Address and Other Basic Network Information" on page 121. IPv6 Management Features PowerConnect 8000/8100-series switches provide IPv6 support for many standard management features including HTTP, HTTPS/SSL, Telnet, SSH, SNMP, SNTP, TFTP, and traceroute. Dual Software Images PowerConnect 8000/8100-series switches can store up to two software images. The dual image feature allows you to upgrade the switch without deleting the older software image. You designate one image as the active image and the other image as the backup image. For information about managing the switch image, see "Managing Images and Files" on page 309. all-guides com

You can upload and download files such as configuration files and system

images by using HTTP (web only), TFTP, Secure FTP (SFTP), or Secure Copy (SCP). Configuration file uploads from the switch to a server are a good way to back up the switch configuration. You can also download a configuration file from a server to the switch to restore the switch to the configuration in the downloaded file. For information about uploading, downloading, and copying files, see "Managing Images and Files" on page 309. Switch Database Management Templates Switch Database Management (SDM) templates enable you to reallocate system resources to support a different mix of features based on your network requirements. PowerConnect 8000/8100-series switches support the following three templates: • Dual IPv4 and IPv6 (default) • IPv4 Routing • IPv4 Data Center For information about setting the SDM template, see "Managing General System Settings" on page 239. Automatic Installation of Firmware and Configuration The Auto Install feature allows the switch to upgrade or downgrade to a newer software image and update the configuration file automatically during device initialization with limited administrative configuration on the device. The switch can obtain the necessary information from a DHCP server on the network. For information about Auto Install, see "Automatically Updating the Image and Configuration" on page 337.

sFlow is the standard for monitoring high-speed switched and routed

networks. sFlow technology is built into network equipment and gives complete visibility into network activity, enabling effective management and control of network resources. The PowerConnect 8000/8100-series switches support sFlow version 5. For information about configuring managing sFlow settings, see "Monitoring Switch Traffic" on page 355. SNMP Alarms and Trap Logs The system logs events with severity codes and timestamps. The events are sent as SNMP traps to a trap recipient list. For information about configuring SNMP traps and alarms, see "Configuring SNMP" on page 273. CDP Interoperability through ISDP Industry Standard Discovery Protocol (ISDP) allows the PowerConnect switch to interoperate with Cisco devices running the Cisco Discovery Protocol (CDP). ISDP is a proprietary Layer 2 network protocol which inter- operates with Cisco network equipment and is used to share information between neighboring devices (routers, bridges, access servers, and switches). For information about configuring ISDP settings, see "Discovering Network Devices" on page 651. Remote Monitoring (RMON) RMON is a standard Management Information Base (MIB) that defines current and historical MAC-layer statistics and control objects, allowing real- time information to be captured across the entire network. For information about configuring managing RMON settings, see "Monitoring Switch Traffic" on page 355.

For information about creating and maintaining a stack of switches, see

"Managing a Switch Stack" on page 143. High Port Count You can stack PowerConnect 8000-series and 8100-series switches up to six switches high, supporting up to 132 front-panel ports on the PC8024 series and up to 336 front panel ports on a stack of six PC8164 series, when two ports on each unit are configured as stacking ports. The stack can contain any combination of Power Connect 8024 and PowerConnect 8024F switches as long as all switches are running the same firmware version. Single IP Management When multiple switches are connected together through the stack ports, they operate as a single unit with a larger port count. The stack operates and is managed as a single entity. One switch acts as the master, and the entire stack is managed through the management interface (Web, CLI, or SNMP) of the stack master. Automatic Firmware Update for New Stack Members By default, if a switch is added to a stack and the switch is running a different backup version of firmware than the active version on the stack master, the backup firmware on the new member is automatically updated to match the stack master, the backup version of firmware on the new member is activated, and the new member is rebooted.

Master Failover with Transparent Transition

The stacking feature supports a standby or backup unit that assumes the stack master role if the stack master fails. As soon as a stack master failure is detected, the standby unit initializes the control plane and enables all other stack units with the current configuration. The standby unit maintains a synchronized copy of the running configuration for the stack. Nonstop Forwarding on the Stack The Nonstop Forwarding (NSF) feature allows the forwarding plane of stack units to continue to forward packets while the control and management planes restart as a result of a power failure, hardware failure, or software fault on the stack master and allows the standby switch to quickly takeover as the master. Hot Add/Delete and Firmware Synchronization You can add and remove units to and from the stack without cycling the power. When you add a unit, the Stack Firmware Synchronization feature automatically synchronizes the firmware version with the version running on the stack master. The synchronization operation may result in either an upgrade or a downgrade of firmware on the mismatched stack member. In addition, the running-config on the member is updated to match the master switch. The startup-config on the standby and member switches is not updated to match the master switch due to configuration changes on the master switch. Saving the startup config on the master switch also saves it to the startup config on all the other stack members.The hardware configuration of every switch is updated to match the master switch (unit number, slot configuration, stack member number, etc.). Security Features Configurable Access and Authentication Profiles You can configure rules to limit access to the switch management interface based on criteria such as access type and source IP address of the management host. You can also require the user to be authenticated locally or by an external server, such as a RADIUS server.

For information about configuring access and authentication profiles, see

"Configuring Authentication, Authorization, and Accounting" on page 179. Password-Protected Management Access Access to the Web, CLI, and SNMP management interfaces is password protected, and there are no default users on the system. For information about configuring local user accounts, see "Configuring Authentication, Authorization, and Accounting" on page 179. Strong Password Enforcement The Strong Password feature enforces a baseline password strength for all locally administered users. Password strength is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. The strength of a password is a function of length, complexity and randomness. Using strong passwords lowers overall risk of a security breach. For information about configuring password settings, see "Configuring Authentication, Authorization, and Accounting" on page 179. TACACS+ Client The switch has a TACACS+ client. TACACS+ provides centralized security for validation of users accessing the switch. TACACS+ provides a centralized user management system while still retaining consistency with RADIUS and other authentication processes. For information about configuring TACACS+ client settings, see "Configuring Authentication, Authorization, and Accounting" on page 179. RADIUS Support The switch has a Remote Authentication Dial In User Service (RADIUS) client and can support up to 32 named authentication and accounting RADIUS servers. The switch also supports RADIUS Attribute 4, which is the configuration of a NAS-IP address. You can also configure the switch to accept RADIUS-assigned VLANs. For information about configuring RADIUS client settings, see "Configuring Authentication, Authorization, and Accounting" on page 179. all-guides com

The switch supports Secure Shell (SSH) for secure, remote connections to

the CLI and Secure Sockets Layer (SSL) to increase security when accessing the web-based management interface. For information about configuring SSH and SSL settings, see "Configuring Authentication, Authorization, and Accounting" on page 179. Inbound Telnet Control You can configure the switch to prevent new Telnet sessions from being established with the switch. Additionally, the Telnet port number is configurable. For information about configuring inbound Telnet settings, see "Configuring Authentication, Authorization, and Accounting" on page 179. Denial of Service The switch supports configurable Denial of Service (DoS) attack protection for eight different types of attacks. For information about configuring DoS settings, see "Configuring Port and System Security" on page 469. Port Protection A port may be put into the disabled state for any of the following reasons: • BPDU Storm Protection: By default, if Spanning Tree Protocol (STP) bridge protocol data units (BPDUs) are received at a rate of 15pps or greater for three consecutive seconds on a port, the port will be diagnostically disabled. The threshold is not configurable. • DHCP Snooping: If DHCP packets are received on a port at a rate that exceeds 15 pps, the port will be diagnostically disabled. The threshold is configurable up to 300 pps for up to 15s long using the ip dhcp snooping limit command. DHCP snooping is disabled by default. The default protection limit is 15 pps.

Dynamic ARP Inspection: By default, if Dynamic ARP Inspection packets

are received on a port at a rate that exceeds 15 pps for 1 second, the port will be diagnostically disabled. The threshold is configurable up to 300 pps and the burst is configurable up to 15s long using the ip arp inspection limit command. A port that is diagnostically disabled due to exceeding one of the above limits may be returned to service using the no shut command. Captive Portal The Captive Portal feature blocks clients from accessing the network until user verification has been established. When a user attempts to connect to the network through the switch, the user is presented with a customized Web page that might contain username and password fields or the acceptable use policy. You can require users to be authenticated by a local or remote RADIUS database before access is granted. For information about configuring the Captive Portal features, see "Configuring Captive Portal" on page 413. Dot1x Authentication (IEEE 802.1X) Dot1x authentication enables the authentication of system users through a local internal server or an external server. Only authenticated and approved system users can transmit and receive data. Supplicants are authenticated using the Extensible Authentication Protocol (EAP). PEAP, EAP-TTL, EAP- TTLS, and EAP-TLS are supported for remote authentication servers. Local (IAS) authentication supports EAP-MD5 only. For information about configuring IEEE 802.1X settings, see "Configuring Port and System Security" on page 469. MAC-Based 802.1X Authentication MAC-based authentication allows multiple supplicants connected to the same port to each authenticate individually. For example, a system attached to the port might be required to authenticate in order to gain access to the network, while a VoIP phone might not need to authenticate in order to send voice traffic through the port. For information about configuring MAC-based 802.1X authentication, see "Configuring Port and System Security" on page 469.

Dot1x Monitor Mode

Monitor mode can be enabled in conjunction with Dot1x authentication to allow network access even when the user fails to authenticate. The switch logs the results of the authentication process for diagnostic purposes. The main purpose of this mode is to help troubleshoot the configuration of a Dot1x authentication on the switch without affecting the network access to the users of the switch. For information about enabling the Dot1X Monitor mode, see "Configuring Port and System Security" on page 469. MAC-Based Port Security The port security feature limits access on a port to users with specific MAC addresses. These addresses are manually defined or learned on that port. When a frame is seen on a locked port, and the frame source MAC address is not tied to that port, the protection mechanism is invoked. For information about configuring MAC-based port security, see "Configuring Port and System Security" on page 469. Access Control Lists (ACL) Access Control Lists (ACLs) ensure that only authorized users have access to specific resources while blocking off any unwarranted attempts to reach network resources. ACLs are used to provide traffic flow control, restrict contents of routing updates, decide which types of traffic are forwarded or blocked, and above all provide security for the network. The switch supports the following ACL types: • IPv4 ACLs • IPv6 ACLs • MAC ACLs For all ACL types, you can apply the ACL rule when the packet enters or exits the physical port, LAG, or VLAN interface. For information about configuring ACLs, see "Configuring Access Control Lists" on page 513.

With the Time-based ACL feature, you can define when an ACL is in effect

and the amount of time it is in effect. For information about configuring time-based ACLs, see "Configuring Access Control Lists" on page 513. IP Source Guard (IPSG) IP source guard (IPSG) is a security feature that filters IP packets based on the source ID. The source ID may either be source IP address or a source IP address source MAC address pair. For information about configuring IPSG, see "Snooping and Inspecting Traffic" on page 753. DHCP Snooping DHCP Snooping is a security feature that monitors DHCP messages between a DHCP client and DHCP server. It filters harmful DHCP messages and builds a bindings database of (MAC address, IP address, VLAN ID, port) tuples that are specified as authorized. DHCP snooping can be enabled globally and on specific VLANs. Ports within the VLAN can be configured to be trusted or untrusted. DHCP servers must be reached through trusted ports. For information about configuring DHCP Snooping, see "Snooping and Inspecting Traffic" on page 753. Dynamic ARP Inspection Dynamic ARP Inspection (DAI) is a security feature that rejects invalid and malicious ARP packets. The feature prevents a class of man-in-the-middle attacks, where an unfriendly station intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting neighbors. The malicious station sends ARP requests or responses mapping another station's IP address to its own MAC address. Dynamic ARP Inspection relies on DHCP Snooping. For information about configuring DAI, see "Snooping and Inspecting Traffic" on page 753.

Protected Ports (Private VLAN Edge)

Private VLAN Edge (PVE) ports are a Layer 2 security feature that provides port-based security between ports that are members of the same VLAN. It is an extension of the common VLAN. Traffic from protected ports is sent only to the uplink ports and cannot be sent to other ports within the VLAN. For information about configuring IPSG, see "Configuring Port-Based Traffic Control" on page 679. Switching Features Flow Control Support (IEEE 802.3x) Flow control enables lower speed switches to communicate with higher speed switches by requesting that the higher speed switch refrains from sending packets. Transmissions are temporarily halted to prevent buffer overflows. For information about configuring flow control, see "Configuring Port-Based Traffic Control" on page 679. Head of Line Blocking Prevention Head of Line (HOL) blocking prevention prevents traffic delays and frame loss caused by traffic competing for the same egress port resources. HOL blocking queues packets, and the packets at the head of the queue are forwarded before packets at the end of the queue. Alternate Store and Forward (ASF) The Alternate Store and Forward (ASF) feature reduces latency for large packets. When ASF is enabled, the memory management unit (MMU) can forward a packet to the egress port before it has been entirely received on the Cell Buffer Pool (CBP) memory. AFS, which is also known as cut-through mode, is configurable through the command-line interface. For information about how to configure the AFS feature, see the CLI Reference Guide available at support.dell.com/manuals. all-guides com

Jumbo Frames Support

Jumbo frames enable transporting data in fewer frames to ensure less overhead, lower processing time, and fewer interrupts. For information about configuring the port MTU, see "Configuring Port Characteristics" on page 451. Auto-MDI/MDIX Support Your switch supports auto-detection between crossed and straight-through cables. Media-Dependent Interface (MDI) is the standard wiring for end stations, and the standard wiring for hubs and switches is known as Media- Dependent Interface with Crossover (MDIX). VLAN-Aware MAC-based Switching Packets arriving from an unknown source address are sent to the CPU and added to the Hardware Table. Future packets addressed to or from this address are more efficiently forwarded. Back Pressure Support On half-duplex links, a receiver may prevent buffer overflows by jamming the link so that it is unavailable for additional traffic. On full-duplex links, a receiver may send a PAUSE frame indicating that the transmitter should cease transmission of frames for a specified period. When flow control is enabled, the PowerConnect 8000/8100-series switches will observe received PAUSE frames or jamming signals, but will not issue them when congested.

Auto negotiation allows the switch to advertise modes of operation. The auto

negotiation function provides the means to exchange information between two switches that share a point-to-point link segment, and to automatically configure both switches to take maximum advantage of their transmission capabilities. PowerConnect 8000/8100-series switches enhance auto negotiation by providing configuration of port advertisement. Port advertisement allows the system administrator to configure the port speeds that are advertised. For information about configuring auto negotiation, see "Configuring Port Characteristics" on page 451. Broadcast Storm Control When Layer 2 frames are forwarded, broadcast, unknown unicast, and multicast frames are flooded to all ports on the relevant virtual local area network (VLAN). The flooding occupies bandwidth, and loads all nodes connected on all ports. Storm control limits the amount of broadcast, unknown unicast, and multicast frames accepted and forwarded by the switch. For information about configuring Broadcast Storm Control settings, see "Configuring Port-Based Traffic Control" on page 679. Port Mirroring Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from up to four source ports to a monitoring port. The switch also supports flow-based mirroring, which allows you to copy certain types of traffic to a single destination port. This provides flexibility— instead of mirroring all ingress or egress traffic on a port the switch can mirror a subset of that traffic. You can configure the switch to mirror flows based on certain kinds of Layer 2, Layer 3, and Layer 4 information. For information about configuring port mirroring, see "Monitoring Switch Traffic" on page 355.

Static and Dynamic MAC Address Tables

You can add static entries to the switch’s MAC address table and configure the aging time for entries in the dynamic MAC address table. You can also search for entries in the dynamic table based on several different criteria. For information about viewing and managing the MAC address table, see "Managing the MAC Address Table" on page 849. Link Layer Discovery Protocol (LLDP) The IEEE 802.1AB defined standard, Link Layer Discovery Protocol (LLDP), allows the switch to advertise major capabilities and physical descriptions. This information can help you identify system topology and detect bad configurations on the LAN. For information about configuring LLDP, settings see "Discovering Network Devices" on page 651. Link Layer Discovery Protocol (LLDP) for Media Endpoint Devices The Link Layer Discovery Protocol for Media Endpoint Devices (LLDP- MED) provides an extension to the LLDP standard for network configuration and policy, device location, Power over Ethernet management, and inventory management. For information about configuring LLDP-MED, settings see "Discovering Network Devices" on page 651. Priority-based Flow Control (PFC) The Priority-based Flow Control feature allows the switch to pause or inhibit transmission of individual priorities within a single physical link. By configuring PFC to pause a congested priority (priorities) independently, protocols that are highly loss sensitive can share the same link with traffic that has different loss tolerances. Priorities are differentiated by the priority field of the 802.1Q VLAN header. The PowerConnect 8000-series and 8100-series switches support lossless transport of frames on up to two priority classes. NOTE: An interface that is configured for PFC is automatically disabled for 802.3x flow control.

For information about configuring the PFC feature, see "Configuring Data

Center Bridging Features" on page 809. Data Center Bridging Exchange (DBCx) Protocol The Data Center Bridging Exchange Protocol (DCBx) is used by DCB devices to exchange configuration information with directly connected peers. The protocol is also used to detect misconfiguration of the peer DCB devices and, optionally, for configuration of peer DCB devices. For information about configuring DCBx settings, see "Configuring Data Center Bridging Features" on page 809. DCBx is a link-local protocol and operates only on individual links. When configuring FIP snooping on a port channel, ensure that all of the physical links in the port channel utilize the same auto configuration setting. Enhanced Transmission Selection Enhanced Transmission Selection (ETS) allows the switch to allocate bandwidth to traffic classes and share unused bandwidth with lower-priority traffic classes while coexisting with strict-priority traffic classes. ETS is supported on the PowerConnect 8100-series switches and can be configured manually or automatically using the auto configuration feature. For more information about ETS, see "Enhanced Transmission Selection" on page 831. Fibre Channel over Ethernet (FCoE) Initialization Protocol Snooping The FCoE Initialization Protocol (FIP) is used to perform the functions of FC_BB_E device discovery, initialization, and maintenance as defined in the ANSI T11 FC-BB-5 specification. The PC8024/PC8024F switch supports FIP snooping, which is a frame inspection method used by FIP Snooping Bridges to monitor FIP frames and apply policies based upon the L2 header information in those frames. For information about configuring the FIP Snooping feature, see "Configuring Data Center Bridging Features" on page 809.

Cisco Protocol Filtering

The Cisco Protocol Filtering feature (also known as Link Local Protocol Filtering) filters Cisco protocols that should not normally be relayed by a bridge. The group addresses of these Cisco protocols do not fall within the IEEE defined range of the 802.1D MAC Bridge Filtered MAC Group Addresses (01-80-C2-00-00-00 to 01-80-C2-00-00-0F). For information about configuring LLPF, settings see "Configuring Port- Based Traffic Control" on page 679. DHCP Layer 2 Relay This feature permits Layer 3 Relay agent functionality in Layer 2 switched networks. The switch supports L2 DHCP relay configuration on individual ports, link aggregation groups (LAGs) and VLANs. For information about configuring L2 DHCP Relay settings see "Configuring L2 and L3 Relay Features" on page 919. Virtual Local Area Network Supported Features For information about configuring VLAN features see "Configuring VLANs" on page 551. VLAN Support VLANs are collections of switching ports that comprise a single broadcast domain. Packets are classified as belonging to a VLAN based on either the VLAN tag or a combination of the ingress port and packet contents. Packets sharing common attributes can be groups in the same VLAN. The PowerConnect 8000/8100-series switches are in full compliance with IEEE 802.1Q VLAN tagging. Port-Based VLANs Port-based VLANs classify incoming packets to VLANs based on their ingress port. When a port uses 802.1X port authentication, packets can be assigned to a VLAN based on the result of the 802.1X authentication a client uses when it accesses the switch. This feature is useful for assigning traffic to Guest VLANs or Voice VLANs. all-guides com

IP Subnet-based VLAN

This feature allows incoming untagged packets to be assigned to a VLAN and traffic class based on the source IP address of the packet. MAC-based VLAN This feature allows incoming untagged packets to be assigned to a VLAN and traffic class based on the source MAC address of the packet. IEEE 802.1v Protocol-Based VLANs VLAN classification rules are defined on data-link layer (Layer 2) protocol identification. Protocol-based VLANs are used for isolating Layer 2 traffic for differing Layer 3 protocols. GARP and GVRP Support The switch supports the configuration of Generic Attribute Registration Protocol (GARP) timers GARP VLAN Registration Protocol (GVRP) relies on the services provided by GARP to provide IEEE 802.1Q-compliant VLAN pruning and dynamic VLAN creation on 802.1Q trunk ports. When GVRP is enabled, the switch registers and propagates VLAN membership on all ports that are part of the active spanning tree protocol topology. For information about configuring GARP timers see "Configuring L2 Multicast Features" on page 695. Voice VLAN The Voice VLAN feature enables switch ports to carry voice traffic with defined priority. The priority level enables the separation of voice and data traffic coming onto the port. Voice VLAN is the preferred solution for enterprises wishing to deploy voice services in their network.

The Guest VLAN feature allows a switch to provide a distinguished service to

unauthenticated users. This feature provides a mechanism to allow visitors and contractors to have network access to reach external network with no ability to browse information on the internal LAN. For information about configuring the Guest VLAN see "Configuring Port and System Security" on page 469. Double VLANs The Double VLAN feature (IEEE 802.1QinQ) allows the use of a second tag on network traffic. The additional tag helps differentiate between customers in the Metropolitan Area Networks (MAN) while preserving individual customer’s VLAN identification when they enter their own 802.1Q domain.

Spanning Tree Protocol Features

For information about configuring Spanning Tree Protocol features, see "Configuring the Spanning Tree Protocol" on page 619. Spanning Tree Protocol (STP) Spanning Tree Protocol (IEEE 802.1D) is a standard requirement of Layer 2 switches that allows bridges to automatically prevent and resolve L2 forwarding loops. Spanning Tree Port Settings The STP feature supports a variety of per-port settings including path cost, priority settings, Port Fast mode, STP Root Guard, Loop Guard, TCN Guard, and Auto Edge. These settings are also configurable per-LAG. Rapid Spanning Tree Rapid Spanning Tree Protocol (RSTP) detects and uses network topologies to enable faster spanning tree convergence after a topology change, without creating forwarding loops. The port settings supported by STP are also supported by RSTP. Multiple Spanning Tree Multiple Spanning Tree (MSTP) operation maps VLANs to spanning tree instances. Packets assigned to various VLANs are transmitted along different paths within MSTP Regions (MST Regions). Regions are one or more interconnected MSTP bridges with identical MSTP settings. The MSTP standard lets administrators assign VLAN traffic to unique paths. The switch supports IEEE 802.1Q-2005, which is a version of corrects problems associated with the previous version, provides for faster transition- to-forwarding, and incorporates new features for a port (restricted role and restricted TCN).

Bridge Protocol Data Unit (BPDU) Guard

Spanning Tree BPDU Guard is used to disable the port in case a new device tries to enter the already existing topology of STP. Thus devices, which were originally not a part of STP, are not allowed to influence the STP topology. BPDU Filtering When spanning tree is disabled on a port, the BPDU Filtering feature allows BPDU packets received on that port to be dropped. Additionally, the BPDU Filtering feature prevents a port in Port Fast mode from sending and receiving BPDUs. A port in Port Fast mode is automatically placed in the forwarding state when the link is up to increase convergence time. Link Aggregation Features For information about configuring link aggregation (port-channel) features, see "Configuring Link Aggregation" on page 791. Link Aggregation Up to eight ports can combine to form a single Link Aggregation Group (LAG). This enables fault tolerance protection from physical link disruption, higher bandwidth connections and improved bandwidth granularity. Per IEEE 802.1AX, only links with the same operational characteristics, such as speed and duplex setting, may be aggregated. PowerConnect switches aggregate links only if they have the same operational speed and duplex setting, as opposed to the configured speed and duplex setting. This allows operators to aggregate links that use auto negotiation to set values for speed and duplex. Dissimilar ports will not become active in the LAG if their operational settings do not match those of the first member of the LAG. PowerConnect switches also support setting the MTU on a LAG. When a link becomes active in a LAG, its MTU is dynamically changed to the LAG MTU. When the link leaves the LAG, its MTU reverts to the link setting. Link Aggregate Control Protocol (LACP) Link Aggregate Control Protocol (LACP) uses peer exchanges across links to determine, on an ongoing basis, the aggregation capability of various links, and continuously provides the maximum level of aggregation capability

achievable between a given pair of systems. LACP automatically determines,

configures, binds, and monitors the binding of ports to aggregators within the system. all-guides com

Address Resolution Protocol (ARP) Table Management

You can create static ARP entries and manage many settings for the dynamic ARP table, such as age time for entries, retries, and cache size. For information about managing the ARP table, see "Configuring IP Routing" on page 895. VLAN Routing PowerConnect 8000/8100-series switches support VLAN routing. You can also configure the software to allow traffic on a VLAN to be treated as if the VLAN were a router port. For information about configuring VLAN routing interfaces, see "Configuring Routing Interfaces" on page 855. IP Configuration The switch IP configuration settings to allow you to configure network information for VLAN routing interfaces such as IP address and subnet mask, MTU size, and ICMP redirects. Global IP configuration settings for the switch allow you to enable or disable the generation of several types of ICMP messages and enable or disable the routing mode. For information about managing global IP settings, see "Configuring IP Routing" on page 895. Open Shortest Path First (OSPF) Open Shortest Path First (OSPF) is a dynamic routing protocol commonly used within medium-to-large enterprise networks. OSPF is an interior gateway protocol (IGP) that operates within a single autonomous system. For information about configuring OSPF, see "Configuring OSPF and OSPFv3" on page 943.

BOOTP/DHCP Relay Agent

The switch BootP/DHCP Relay Agent feature relays BootP and DHCP messages between DHCP clients and DHCP servers that are located in different IP subnets. For information about configuring the BootP/DHCP Relay agent, see "Configuring L2 and L3 Relay Features" on page 919. IP Helper and UDP Relay The IP Helper and UDP Relay features provide the ability to relay various protocols to servers on a different subnet. For information about configuring the IP helper and UDP relay features, see "Configuring L2 and L3 Relay Features" on page 919. Routing Information Protocol Routing Information Protocol (RIP), like OSPF, is an IGP used within an autonomous Internet system. RIP is an IGP that is designed to work with moderate-size networks. For information about configuring RIP, see "Configuring RIP" on page 1031. Router Discovery For each interface, you can configure the Router Discovery Protocol (RDP) to transmit router advertisements. These advertisements inform hosts on the local network about the presence of the router. For information about configuring router discovery, see "Configuring IP Routing" on page 895. Routing Table The routing table displays information about the routes that have been dynamically learned. You can configure static and default routes and route preferences. A separate table shows the routes that have been manually configured. For information about viewing the routing table, see "Configuring IP Routing" on page 895.

Virtual Router Redundancy Protocol (VRRP)

VRRP provides hosts with redundant routers in the network topology without any need for the hosts to reconfigure or know that there are multiple routers. If the primary (master) router fails, a secondary router assumes control and continues to use the virtual router IP (VRIP) address. VRRP Route Interface Tracking extends the capability of VRRP to allow tracking of specific route/interface IP states within the router that can alter the priority level of a virtual router for a VRRP group. For information about configuring VRRP settings, see "Configuring VRRP" on page 1045. Tunnel and Loopback Interfaces PowerConnect 8000/8100-series switches support the creation, deletion, and management of tunnel and loopback interfaces. Tunnel interfaces facilitate the transition of IPv4 networks to IPv6 networks. A loopback interface is always expected to be up, so you can configure a stable IP address that other network devices use to contact or identify the switch. For information about configuring tunnel and loopback interfaces, see "Configuring Routing Interfaces" on page 855. IPv6 Routing Features IPv6 Configuration The switch supports IPv6, the next generation of the Internet Protocol. You can globally enable IPv6 on the switch and configure settings such as the IPv6 hop limit and ICMPv6 rate limit error interval. You can also control whether IPv6 is enabled on a specific interface. The switch supports the configuration of many per-interface IPv6 settings including the IPv6 prefix and prefix length. For information about configuring general IPv6 routing settings, see "Configuring IPv6 Routing" on page 1069.

Because IPv4 and IPv6 can coexist on a network, the router on such a network

needs to forward both traffic types. Given this coexistence, each switch maintains a separate routing table for IPv6 routes. The switch can forward IPv4 and IPv6 traffic over the same set of interfaces. For information about configuring IPv6 routes, see "Configuring IPv6 Routing" on page 1069. OSPFv3 OSPFv3 provides a routing protocol for IPv6 networking. OSPFv3 is a new routing component based on the OSPF version 2 component. In dual stack IPv6, you can configure and use both OSPF and OSPFv3 components. For information about configuring OSPFv3, see "Configuring OSPF and OSPFv3" on page 943. DHCPv6 DHCPv6 incorporates the notion of the “stateless” server, where DHCPv6 is not used for IP address assignment to a client, rather it only provides other networking information such as DNS, Network Time Protocol (NTP), and/or Session Initiation Protocol (SIP) information. For information about configuring DHCPv6 settings, see "Configuring DHCPv6 Server and Relay Settings" on page 1093.

Quality of Service (QoS) Features

Differentiated Services (DiffServ) The QoS Differentiated Services (DiffServ) feature allows traffic to be classified into streams and given certain QoS treatment in accordance with defined per-hop behaviors. PowerConnect 8000/8100-series switches support both IPv4 and IPv6 packet classification. For information about configuring DiffServ, see "Configuring Differentiated Services" on page 1113. Class Of Service (CoS) The Class Of Service (CoS) queueing feature lets you directly configure certain aspects of switch queuing. This provides the desired QoS behavior for different types of network traffic when the complexities of DiffServ are not required. CoS queue characteristics, such as minimum guaranteed bandwidth and transmission rate shaping, are configurable at the queue (or port) level. For information about configuring CoS, see "Configuring Class-of-Service" on page 1143. Auto Voice over IP (VoIP) This feature provides ease of use for the user in setting up VoIP for IP phones on a switch. This is accomplished by enabling a VoIP profile that a user can select on a per port basis. For information about configuring Auto VoIP, see "Configuring Auto VoIP" on page 1161. NOTE: Some features that can affect QoS, such as ACLs and Voice VLAN, are described in other sections within this chapter. all-guides com

Internet Small Computer System Interface (iSCSI) Optimization

The iSCSI Optimization feature helps network administrators track iSCSI traffic between iSCSI initiator and target systems. This is accomplished by monitoring, or snooping traffic to detect packets used by iSCSI stations in establishing iSCSI sessions and connections. Data from these exchanges may optionally be used to create classification rules to assign the traffic between the stations to a configured traffic class. This affects how the packets in the flow are queued and scheduled for egress on the destination port. For information about configuring iSCSI settings, see "Configuring iSCSI Optimization" on page 395. Layer 2 Multicast Features For information about configuring L2 multicast features, see "Configuring L2 Multicast Features" on page 695. MAC Multicast Support Multicast service is a limited broadcast service that allows one-to-many and many-to-many connections. In Layer 2 multicast services, a single frame addressed to a specific multicast address is received, and copies of the frame to be transmitted on each relevant port are created. IGMP Snooping Internet Group Management Protocol (IGMP) Snooping is a feature that allows a switch to forward multicast traffic intelligently on the switch. Multicast traffic is traffic that is destined to a host group. Host groups are identified by the destination MAC address, i.e. the range 01:00:5e:00:00:00 to 01:00:5e:7f:ff:ff:ff for IPv4 multicast traffic or 33:33:xx:xx:xx:xx for IPv6 multicast traffic. Based on the IGMP query and report messages, the switch forwards traffic only to the ports that request the multicast traffic. This prevents the switch from broadcasting the traffic to all ports and possibly affecting network performance.

IGMP Snooping Querier

When Protocol Independent Multicast (PIM) and IGMP are enabled in a network with IP multicast routing, the IP multicast router acts as the IGMP querier. However, if it is desirable to keep the multicast network Layer 2 switched only, the IGMP Snooping Querier can perform the query functions of a Layer 3 multicast router. MLD Snooping In IPv4, Layer 2 switches can use IGMP Snooping to limit the flooding of multicast traffic by dynamically configuring Layer 2 interfaces so that multicast traffic is forwarded to only those interfaces associated with IP multicast address. In IPv6, MLD snooping performs a similar function. With MLD snooping, IPv6 multicast data is selectively forwarded to a list of ports intended to receive the data (instead of being flooded to all of the ports in a VLAN). This list is constructed by snooping IPv6 multicast control packets. Multicast VLAN Registration The Multicast VLAN Registration (MVR) protocol, like IGMP Snooping, allows a Layer 2 switch to listen to IGMP frames and forward the multicast traffic only to the receivers that request it. Unlike IGMP Snooping, MVR allows the switch to listen across different VLANs. MVR uses a dedicated VLAN, which is called the multicast VLAN, to forward multicast traffic over the Layer 2 network to the various VLANs that have multicast receivers as members.

Layer 3 Multicast Features

For information about configuring L3 multicast features, see "Managing IPv4 and IPv6 Multicast" on page 1167. Distance Vector Multicast Routing Protocol Distance Vector Multicast Routing Protocol (DVMRP) exchanges probe packets with all DVMRP-enabled routers, establishing two way neighboring relationships and building a neighbor table. It exchanges report packets and creates a unicast topology table, which is used to build the multicast routing table. This multicast route table is then used to route the multicast packets. Internet Group Management Protocol The Internet Group Management Protocol (IGMP) is used by IPv4 systems (hosts and routers) to report their IP multicast group memberships to any neighboring multicast routers. PowerConnect 8000/8100-series switches perform the “multicast router part” of the IGMP protocol, which means it collects the membership information needed by the active multicast router. IGMP Proxy The IGMP Proxy feature allows the switch to act as a proxy for hosts by sending IGMP host messages on behalf of the hosts that the switch discovered through standard IGMP router interfaces. Protocol Independent Multicast—Dense Mode Protocol Independent Multicast (PIM) is a standard multicast routing protocol that provides scalable inter-domain multicast routing across the Internet, independent of the mechanisms provided by any particular unicast routing protocol. The Protocol Independent Multicast-Dense Mode (PIM- DM) protocol uses an existing Unicast routing table and a Join/Prune/Graft mechanism to build a tree. PIM-DM creates source-based shortest-path distribution trees, making use of reverse path forwarding (RPF).

Protocol Independent Multicast—Sparse Mode

Protocol Independent Multicast-Sparse Mode (PIM-SM) is used to efficiently route multicast traffic to multicast groups that may span wide area networks, and where bandwidth is a constraint. PIM-SM uses shared trees by default and implements source-based trees for efficiency. This data threshold rate is used to toggle between trees. Protocol Independent Multicast—Source Specific Multicast Protocol Independent Multicast—Source Specific Multicast (PIM-SSM) is a subset of PIM-SM and is used for one-to-many multicast routing applications, such as audio or video broadcasts. PIM-SSM does not use shared trees. Protocol Independent Multicast IPv6 Support PIM-DM and PIM-SM support IPv6 routes. MLD/MLDv2 (RFC2710/RFC3810) MLD is used by IPv6 systems (listeners and routers) to report their IP multicast addresses memberships to any neighboring multicast routers. The implementation of MLD v2 is backward compatible with MLD v1. MLD protocol enables the IPv6 router to discover the presence of multicast listeners, the nodes that want to receive the multicast data packets, on its directly attached interfaces. The protocol specifically discovers which multicast addresses are of interest to its neighboring nodes and provides this information to the multicast routing protocol that make the decision on the flow of the multicast data packets.

PowerConnect 8164F Front Panel

PowerConnect 8164F switches can be stacked with other PowerConnect 81xx switches using the 10G or 40G SFP+ or QSFP modules in the module bay or fixed QSFP ports. Hot-Pluggable Interface Modules The PowerConnect 8132, 8132F, 8164, and 8164F switches support the following hot-pluggable interface modules: • PC8100-QSFP - 2 x 40G QSFP port module - defaults to 2x40G • PC8100-SFP+ - 4 x SFP+ port module - defaults to 4x10G mode • PC8100-10GBT - 4 x 10GBase-T ports module - defaults to 4x10G mode • Blank module - defaults to 10G mode A reboot is necessary when a hot-pluggable module is replaced with a module of different type. Specifically, changing from a 40G module to a 10G module or from a 10G module to a 40G module requires a reboot. Plug-in modules with any port configured as a stacking port are not hot-swappable. Remove the stack-port configuration from a slot before plugging in a module. You must execute a no slot or clear config command prior to inserting the new module. Note that changing the role of a port from stacking to Ethernet or vice-versa also requires a switch reboot. NOTE: The PowerConnect 8024 and 8024F switches do not support hot-swappable plug-in modules. 10GbE Fiber Ports Fixed QSFP ports Module bay USB port

USB Port (Power Connect 8100-series switches only)

The Type-A, female USB port supports a USB 2.0-compliant flash memory drive. The PowerConnect switch can read or write to a flash drive formatted as FAT-32. You can use a USB flash drive to copy switch configuration files and images between the USB flash drive and the switch. You can also use the USB flash drive to move and copy configuration files and images from one switch to other switches in the network. The USB port does not support any other type of USB device. Port and System LEDs The front panel contains light emitting diodes (LEDs) to indicate port status. For information about the status that the LEDs indicate, see "LED Definitions" on page 97. PowerConnect 8000-series and 8100-series Back Panel • Console Port • Out-of-Band Management Port • Power Supplies • Ventilation System

The console port is for management through a serial interface. This port

provides a direct connection to the switch and allows you to access the CLI from a console terminal connected to the port through the provided serial cable (RJ-45 to female DB-9 connectors). The console port supports asynchronous data of eight data bits, one stop bit, no parity bit, and no flow control. The default baud rate is 9600 bps. Out-of-Band Management Port The Out-of-Band (OOB) management port is a 10/100/1000BASE-T Ethernet port dedicated to remote switch management. Traffic on this port is segregated from operational network traffic on the switch ports and cannot be switched or routed to the operational network. Power Supplies Each PowerConnect 8000-series and 8100-series switch has two power supplies for redundant or loadsharing operation. Each power supply can support 300W. Ventilation System The PC8000-series switches have three removable FANs and the 8100-series have two fans (see "PowerConnect PC8100-Series Back Panel" on page 95). Each switch also has four thermal sensors and a fan speed controller, which can be used to control FAN speeds. You can verify operation by observing the LEDs. CAUTION: Remove the power cable from the modules prior to removing the module itself. Power must not be connected prior to insertion in the chassis. all-guides com
