OL-21522-02 Preface Audience This guide is for the networking professional using the Cisco IOS command-line interface (CLI) to manage the Catalyst 3750-X and 3560-X switch, or the Catalyst 3750-X switch stack, referred to as the switch. Before using this guide, you should have experience working with the Cisco IOS commands and the switch software features. Before using this guide, you should have experience working with the concepts and terminology of Ethernet and local area networking. Purpose This guide provides the information that you need about the Layer 2 and Layer 3 commands that have been created or changed for use with the Catalyst 3750-X and 3560-X switches. For information about the standard Cisco IOS Release 12.2 commands, see the Cisco IOS documentation set available from the Cisco.com home page by selecting Technical Support & Documentation > Documentation > Cisco IOS Software. Note Switches running the LAN base feature set do not support Layer 3 features. This guide does not provide procedures for configuring your switch. For detailed configuration procedures, see the software configuration guide for this release. This guide does not describe system messages you might encounter. For more information, see the system message guide for this release. For documentation updates, see the release notes for this release.

1-1 Catalyst 3750-X and 3560-X Switch Command Reference OL-21522-02 1 Using the Command-Line Interface The Catalyst 3750-X and 3560-X switches are supported by Cisco IOS software. This chapter describes how to use the switch command-line interface (CLI) to configure software features. For a complete description of the commands that support these features, see Chapter 2, “Catalyst 3750-X and 3560-X Switch Cisco IOS Commands.” For information on the boot loader commands, see Appendix A “Catalyst 3750-X and 3560-X Switch Boot Loader Commands.” For information on the debug commands, see Appendix B “Catalyst 3750-X and 3560-X Switch Debug Commands.” For information on the show platform commands, see Appendix C “Catalyst 3750-X and 3560-X Show Platform Commands.” For more information on Cisco IOS Release 12.2, see the Cisco IOS Release 12.2 Command Summary. For task-oriented configuration steps, see the software configuration guide for this release. In this document, IP refers to IP version 4 (IPv4) unless there is a specific reference to IP version 6 (IPv6). Accessing the Switch You manage the switch stack and the stack member interfaces through the stack master (such as a Catalyst 3750-X switch). You cannot manage stack members on an individual switch basis. You can connect to the stack master through the console port or Ethernet management port of one or more stack members. You can connect to the stack master through the console port or Ethernet management port of one or more stack members. Be careful with using multiple CLI sessions to the stack master. Commands you enter in one session are not displayed in the other sessions. Therefore, it is possible to lose track of the session from which you entered commands. Note We recommend using one CLI session when managing the switch stack. If you want to configure a specific stack member port, you must include the stack member number in the CLI command interface notation. For more information about interface notations, see the “Configuring Interfaces” chapter in the software configuration guide for this release. To debug a specific stack member, you can access it from the stack master by using the session stack-member-number privileged EXEC command. The stack member number is appended to the system prompt. For example, Switch-2# is the prompt in privileged EXEC mode for stack member 2, and the system prompt for the stack master is Switch. Only the show and debug commands are available in a CLI session to a specific stack member. Downloaded from www.Manualslib.com manuals search engine

OL-21522-02 Chapter 1 Using the Command-Line Interface CLI Command Modes CLI Command Modes This section describes the CLI command mode structure. Command modes support specific Cisco IOS commands. For example, the interface interface-id command only works when entered in global configuration mode. These are the main command modes for the switch: • User EXEC • Privileged EXEC • Global configuration • Interface configuration • VLAN configuration • Line configuration Table 1-1 lists the main command modes, how to access each mode, the prompt you see in that mode, and how to exit that mode. The prompts listed use the default name Switch. Table 1-1 Command Modes Summary Command Mode Access Method Prompt Exit or Access Next Mode User EXEC This is the first level of access. (For the switch) Change terminal settings, perform basic tasks, and list system information. Switch> Enter the logout command. To enter privileged EXEC mode, enter the enable command. Privileged EXEC From user EXEC mode, enter the enable command. Switch# To exit to user EXEC mode, enter the disable command. To enter global configuration mode, enter the configure command. Global configuration From privileged EXEC mode, enter the configure command. Switch(config)# To exit to privileged EXEC mode, enter the exit or end command, or press Ctrl-Z. To enter interface configuration mode, enter the interface configuration command. Interface configuration From global configuration mode, specify an interface by entering the interface command followed by an interface identification. Switch(config-if)# To exit to privileged EXEC mode, enter the end command, or press Ctrl-Z. To exit to global configuration mode, enter the exit command. Downloaded from www.Manualslib.com manuals search engine

OL-21522-02 Chapter 1 Using the Command-Line Interface CLI Command Modes User EXEC Mode After you access the device, you are automatically in user EXEC command mode. The EXEC commands available at the user level are a subset of those available at the privileged level. In general, use the user EXEC commands to temporarily change terminal settings, perform basic tests, and list system information. The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch> ? Privileged EXEC Mode Because many of the privileged commands configure operating parameters, privileged access should be password-protected to prevent unauthorized use. The privileged command set includes those commands contained in user EXEC mode, as well as the configure privileged EXEC command through which you access the remaining command modes. If your system administrator has set a password, you are prompted to enter it before being granted access to privileged EXEC mode. The password does not appear on the screen and is case sensitive. The privileged EXEC mode prompt is the device name followed by the pound sign (#). Switch# Enter the enable command to access privileged EXEC mode: Switch> enable Switch# The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch# ? To return to user EXEC mode, enter the disable privileged EXEC command. VLAN configuration In global configuration mode, enter the vlan vlan-id command. Switch(config-vlan)# To exit to global configuration mode, enter the exit command. To return to privileged EXEC mode, enter the end command, or press Ctrl-Z. Line configuration From global configuration mode, specify a line by entering the line command. Switch(config-line)# To exit to global configuration mode, enter the exit command. To return to privileged EXEC mode, enter the end command, or press Ctrl-Z.

OL-21522-02 Chapter 1 Using the Command-Line Interface CLI Command Modes Global Configuration Mode Global configuration commands apply to features that affect the device as a whole. Use the configure privileged EXEC command to enter global configuration mode. The default is to enter commands from the management console. When you enter the configure command, a message prompts you for the source of the configuration commands: Switch# configure Configuring from terminal, memory, or network [terminal]? You can specify either the terminal or NVRAM as the source of configuration commands. This example shows you how to access global configuration mode: Switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch(config)# ? To exit global configuration command mode and to return to privileged EXEC mode, enter the end or exit command, or press Ctrl-Z. Interface Configuration Mode Interface configuration commands modify the operation of the interface. Interface configuration commands always follow a global configuration command, which defines the interface type. Use the interface interface-id command to access interface configuration mode. The new prompt means interface configuration mode. Switch(config-if)# The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch(config-if)# ? To exit interface configuration mode and to return to global configuration mode, enter the exit command. To exit interface configuration mode and to return to privileged EXEC mode, enter the end command, or press Ctrl-Z. VLAN Configuration Mode Use this mode to configure normal-range VLANs (VLAN IDs 1 to 1005) or, when VTP mode is transparent, to configure extended-range VLANs (VLAN IDs 1006 to 4094). When VTP mode is transparent, the VLAN and VTP configuration is saved in the running configuration file, and you can save it to the switch startup configuration file by using the copy running-config startup-config privileged EXEC command. The configurations of VLAN IDs 1 to 1005 are saved in the VLAN database if VTP is in transparent or server mode. The extended-range VLAN configurations are not saved in the VLAN database.

OL-21522-02 Chapter 1 Using the Command-Line Interface CLI Command Modes Enter the vlan vlan-id global configuration command to access VLAN configuration mode: Switch(config)# vlan 2000 Switch(config-vlan)# The supported keywords can vary but are similar to the commands available in VLAN configuration mode. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch(config-vlan)# ? For extended-range VLANs, all characteristics except the MTU size must remain at the default setting. To return to global configuration mode, enter exit; to return to privileged EXEC mode, enter end. All the commands except shutdown take effect when you exit config-vlan mode. Line Configuration Mode Line configuration commands modify the operation of a terminal line. Line configuration commands always follow a line command, which defines a line number. Use these commands to change terminal parameter settings line-by-line or for a range of lines. Use the line vty line_number [ending_line_number] command to enter line configuration mode. The new prompt means line configuration mode. The following example shows how to enter line configuration mode for virtual terminal line 7: Switch(config)# line vty 0 7 The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch(config-line)# ? To exit line configuration mode and to return to global configuration mode, use the exit command. To exit line configuration mode and to return to privileged EXEC mode, enter the end command, or press Ctrl-Z. Downloaded from www.Manualslib.com manuals search engine

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands action action Use the action access-map configuration command on the switch stack or on a standalone switch to set the action for the VLAN access map entry. Use the no form of this command to return to the default setting. action {drop | forward} no action Note This command is not supported on switches running the LAN base feature set. Syntax Description Defaults The default action is to forward packets. Command Modes Access-map configuration Command History Usage Guidelines You enter access-map configuration mode by using the vlan access-map global configuration command. If the action is drop, you should define the access map, including configuring any access control list (ACL) names in match clauses, before applying the map to a VLAN, or all packets could be dropped. In access-map configuration mode, use the match access-map configuration command to define the match conditions for a VLAN map. Use the action command to set the action that occurs when a packet matches the conditions. The drop and forward parameters are not used in the no form of the command. Examples This example shows how to identify and apply a VLAN access map vmap4 to VLANs 5 and 6 that causes the VLAN to forward an IP packet if the packet matches the conditions defined in access list al2: Switch(config)# vlan access-map vmap4 Switch(config-access-map)# match ip address al2 Switch(config-access-map)# action forward Switch(config-access-map)# exit Switch(config)# vlan filter vmap4 vlan-list 5-6 You can verify your settings by entering the show vlan access-map privileged EXEC command. drop Drop the packet when the specified conditions are matched. forward Forward the packet when the specified conditions are matched.

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands archive copy-sw Note To successfully use the archive copy-sw privileged EXEC command, you must have downloaded from a TFTP server the images for both the stack member switch being added and the stack master. You use the archive download-sw privileged EXEC command to perform the download. At least one stack member must be running the image that is to be copied to the switch that has incompatible software. You can copy the image to more than one specific stack member by repeating the /destination-system destination-stack-member-number option in the command for each stack member to be upgraded. If you do not specify the destination-stack-member-number, the default is to copy the running image file to all stack members. Using the /safe or /leave-old-sw option can cause the new copied image to fail if there is insufficient flash memory. If leaving the software in place would prevent the new image from fitting in flash memory due to space constraints, an error results. If you used the /leave-old-sw option and did not overwrite the old image when you copied the new one, you can remove the old image by using the delete privileged EXEC command. For more information, see the “delete” section on page 135. Use the /overwrite option to overwrite the image on the flash device with the copied one. If you specify the command without the /overwrite option, the algorithm verifies that the new image is not the same as the one on the switch flash device or is not running on any stack members. If the images are the same, the copy does not occur. If the images are different, the old image is deleted, and the new one is copied. After copying a new image, enter the reload privileged EXEC command to begin using the new image, or specify the /reload or /force-reload option in the archive copy-sw command. You can enter one or more of these options with the source-stack-member-number option: • /destination-system destination-stack-member-number • /force-reload • /leave-old-sw • /no-set-boot • /overwrite • /reload • /safe If you enter the source-stack-member-number option before one of the previous options, you can enter only the archive copy-sw source-stack-member-number command. These are examples of how you can enter the archive copy-sw command: • To copy the running image from a stack member to another stack member and to overwrite the software image in the second stack member’s flash memory (if it already exists) with the copied one, enter the archive copy-sw /destination destination-stack-member-number /overwrite source-stack-member-number command. • To copy the running image from a stack member to another stack member, keep the current software image, and reload the system after the image copies, enter the archive copy-sw /destination destination-stack-member-number /safe /reload source-stack-member-number command.

These options are supported: • Local flash file system syntax on the standalone switch or the stack master: flash: Local flash file system syntax on a stack member: flash member number: The member number can be from 1 to 9. • FTP syntax: ftp:[[//username[:password]@location]/directory]/image-name.tar • HTTP server syntax: http://[[username:password]@]{hostname | host-ip}[/directory]/image-name.tar • Secure HTTP server syntax: https://[[username:password]@]{hostname | host-ip}[/directory]/image-name.tar • Remote Copy Protocol (RCP) syntax: rcp:[[//username@location]/directory]/image-name.tar • Secure Copy Protocol (SCP) syntax for the: scp:[[//username@location]/directory]/image-name.tar • The syntax for the TFTP: tftp:[[//location]/directory]/image-name.tar Downloaded from www.Manualslib.com manuals search engine

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands archive download-sw Command History Usage Guidelines Use the /allow-feature-upgrade option to allow installation of an image with a different feature set, for example, upgrading from the IP base feature set to the IP services feature. You can use the archive download-sw /directory command to specify a directory only once, followed by a tar file or list of tar files to be downloaded, instead of specifying complete paths with each tar file. For example, in a mixed hardware stack, you can enter archive download-sw /directory tftp://10.1.1.10/ c3750-ipservices-tar.122-35.SE.tar c3750e-universal-tar.122-35.SE2.tar The /imageonly option removes the HTML files for the existing image if the existing image is being removed or replaced. Only the Cisco IOS image (without the HTML files) is downloaded. Using the /safe or /leave-old-sw option can cause the new image download to fail if there is insufficient flash memory. If leaving the software in place prevents the new image from fitting in flash memory due to space constraints, an error results. If you used the /leave-old-sw option and did not overwrite the old image when you downloaded the new one, you can remove the old image by using the delete privileged EXEC command. For more information, see the “delete” section on page 135. Use the /no-version-check option if you want to download an image that has a different stack protocol version than the one existing on the switch stack. You must use this option with the /destination-system option to specify the specific stack member to be upgraded with the image. Note Use the /no-version-check option with care. All stack members, including the stack master, must have the same stack protocol version to be in the same switch stack. This option allows an image to be downloaded without first confirming the compatibility of its stack protocol version with the version of the switch stack. You can upgrade more than one specific stack member by repeating the /destination-system option in the command for each stack member to be upgraded. Use the /overwrite option to overwrite the image on the flash device with the downloaded one. If you specify the command without the /overwrite option, the download algorithm verifies that the new image is not the same as the one on the switch flash device or is not running on any stack members. If the images are the same, the download does not occur. If the images are different, the old image is deleted, and the new one is downloaded. After downloading a new image, enter the reload privileged EXEC command to begin using the new image, or specify the /reload or /force-reload option in the archive download-sw command. Use the /directory option to specify a directory for the images. Release Modification 12.2(53)SE2 This command was introduced. Downloaded from www.Manualslib.com manuals search engine

Use the no form of this command to delete the specified ARP access list. arp access-list acl-name no arp access-list acl-name Syntax Description Defaults No ARP access lists are defined. Command Modes Global configuration Command History Usage Guidelines After entering the arp access-list command, you enter ARP access-list configuration mode, and these configuration commands are available: • default: returns a command to its default setting. • deny: specifies packets to reject. For more information, see the “deny (ARP access-list configuration)” section on page 136. • exit: exits ARP access-list configuration mode. • no: negates a command or returns to default settings. • permit: specifies packets to forward. For more information, see the “permit (ARP access-list configuration)” section on page 429. Use the permit and deny access-list configuration commands to forward and to drop ARP packets based on the specified matching criteria. When the ARP ACL is defined, you can apply it to a VLAN by using the ip arp inspection filter vlan global configuration command. ARP packets containing only IP-to-MAC address bindings are compared to the ACL. All other types of packets are bridged in the ingress VLAN without validation. If the ACL permits a packet, the switch forwards it. If the ACL denies a packet because of an explicit deny statement, the switch drops the packet. If the ACL denies a packet because of an implicit deny statement, the switch compares the packet to the list of DHCP bindings (unless the ACL is static, which means that packets are not compared to the bindings). acl-name Name of the ACL.

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands authentication event Usage Guidelines Use this command with the fail, no-response, or event keywords to configure the switch response for a specific action. For server-dead events: • When the switch moves to the critical-authentication state, new hosts trying to authenticate are moved to the critical-authentication VLAN (or critical VLAN). This applies whether the port is in single-host, multiple-host, multiauth, or MDA mode. Authenticated hosts remain in the authenticated VLAN, and the reauthentication timers are disabled. • If a client is running Windows XP and the critical port to which the client is connected is in the critical-authentication state, Windows XP might report that the interface is not authenticated. If the Windows XP client is configured for DHCP and has an IP address from the DHCP server and a critical port receives an EAP-Success message, the DHCP configuration process might not re-initiate. For no-response events: • If you enable a guest VLAN on an IEEE 802.1x port, the switch assigns clients to a guest VLAN when it does not receive a response to its Extensible Authentication Protocol over LAN (EAPOL) request/identity frame or when EAPOL packets are not sent by the client. • The switch maintains the EAPOL packet history. If another EAPOL packet is detected on the port during the lifetime of the link, the guest VLAN feature is disabled. If the port is already in the guest VLAN state, the port returns to the unauthorized state, and authentication restarts. The EAPOL history is cleared. • If the switch port is moved to the guest VLAN (multi-host mode), multiple non-IEEE 802.1x-capable clients are allowed access . If an IEEE 802.1x-capable client joins the same port on which the guest VLAN is configured, the port is put in the unauthorized state in the RADIUS-configured or user-configured access VLAN, and authentication restarts. You can configure any active VLAN except a Remote Switched Port Analyzer (RSPAN) VLAN, a primary private VLAN, or a voice VLAN as an IEEE 802.1x guest VLAN. The guest VLAN feature is supported only on access ports. It is not supported on internal VLANs (routed ports) or trunk ports. • When MAC authentication bypass is enabled on an IEEE 802.1x port, the switch can authorize clients based on the client MAC address if IEEE 802.1x authentication times out while waiting for an EAPOL message exchange. After detecting a client on an IEEE 802.1x port, the switch waits for an Ethernet packet from the client. The switch sends the authentication server a RADIUS-access/request frame with a username and password based on the MAC address. – If authorization succeeds, the switch grants the client access to the network. – If authorization fails, the switch assigns the port to the guest VLAN if one is specified. For more information, see the "Using IEEE 802.1x Authentication with MAC Authentication Bypass" section in the "Configuring IEEE 802.1x Port-Based Authentication" chapter of the software configuration guide. Downloaded from www.Manualslib.com manuals search engine

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands authentication event For authentication-fail events: • If the supplicant fails authentication, the port is moved to a restricted VLAN, and an EAP success message is sent to the supplicant because it i s not notified of the actual authentication failure. – If the EAP success message is not sent, the supplicant tries to authenticate every 60 seconds (the default) by sending an EAP-start message. – Some hosts (for example, devices running Windows XP) cannot implement DHCP until they receive an EAP success message. The restricted VLAN is supported only in single host mode (the default port mode). When a port is placed in a restricted VLAN, the supplicant's MAC address is added to the MAC address table. Any other MAC address on the port is treated as a security violation. • You cannot configure an internal VLANs for Layer 3 ports as a restricted VLAN. You cannot specify the same VLAN as a restricted VLAN and as a voice VLAN. Enable re-authentication with restricted VLANs. If re-authentication is disabled, the ports in the restricted VLANs do not receive re-authentication requests if it is disabled. To start the re-authentication process, the restricted VLAN must receive a link-down event or an Extensible Authentication Protocol (EAP) logoff event from the port. If a host is connected through a hub: – The port might not receive a link-down event when the host is disconnected. – The port might not detect new hosts until the next re-authentication attempt occurs. When you reconfigure a restricted VLAN as a different type of VLAN, ports in the restricted VLAN are also moved and stay in their currently authorized state. Examples This example shows how to configure the authentication event fail command: Switch(config-if)# authentication event fail action authorize vlan 20 This example shows how to configure a no-response action: Switch(config-if)# authentication event no-response action authorize vlan 10 This example shows how to configure a server-response action: Switch(config-if)# authentication event server alive action reinitialize This example shows how to configure a port to send both new and existing hosts to the critical VLAN when the RADIUS server is unavailable.

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands authentication host-mode authentication host-mode Use the authentication host-mode interface configuration command to set the authorization manager mode on a port. authentication host-mode [multi-auth | multi-domain | multi-host | single-host] no authentication host-mode [multi-auth | multi-domain | multi-host | single-host]] Syntax Description Defaults Single host mode is enabled. Command Modes Interface configuration Command History Usage Guidelines Single-host mode should be configured if only one data host is connected. Do not connect a voice device to authenticate on a single-host port. Voice device authorization fails if no voice VLAN is configured on the port. Multi-domain mode should be configured if data host is connected through an IP Phone to the port. Multi-domain mode should be configured if the voice device needs to be authenticated. Multi-auth mode should be configured to allow up to eight devices behind a hub to obtain secured port access through individual authentication. Only one voice device can be authenticated in this mode if a voice VLAN is configured. Multi-host mode also offers port access for multiple hosts behind a hub, but multi-host mode gives unrestricted port access to the devices after the first user gets authenticated. Examples This example shows how to enable multiauth mode on a port: Switch(config-if)# authentication host-mode multi-auth This example shows how to enable multi-domain mode on a port: Switch(config-if)# authentication host-mode multi-domain This example shows how to enable multi-host mode on a port: Switch(config-if)# authentication host-mode multi-host multi-auth Enable multiple-authorization mode (multiauth mode) on the port. multi-domain Enable multiple-domain mode on the port. multi-host Enable multiple-host mode on the port. single-host Enable single-host mode on the port.

To return to the default state, use the no form of this command. authentication linksec policy {must-not-secure | must-secure | should-secure} no authentication linksec policy Syntax Description Defaults The default is to support a link security policy of should secure. Command Modes MKA policy configuration Command History Usage Guidelines The linksec policy might change after a successful reauthentication started by a local timer or a change of authorization (CoA) reauthenticate command. If the policy changes from must-not-secure to must-secure after a reauthentication, the system attempts to secure the session. If the MACsec key does not renegotiate a MACsec connection after a reauthentication, the session is terminated, and all local states are removed. A per-user policy received after authentication overrides the interface configuration policy. Examples This example configures the interface to always secure MACsec sessions: Switch(config)# interface gigabitethernet1/0/3 Switch(config-if)# authentication linksec policy must-secure Switch(config-if)# end You can verify your setting by entering the show authentication sessions privileged EXEC command.

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands auto qos classify Usage Guidelines Use this command to configure the QoS for trusted interfaces within the QoS domain. The QoS domain includes the switch, the network interior, and edge devices that can classify incoming traffic for QoS. Auto-QoS configures the switch for connectivity with a trusted interface. The QoS labels of incoming packets are trusted. For nonrouted ports, the CoS value of the incoming packets is trusted. For routed ports, the DSCP value of the incoming packet is trusted. To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS. This is the policy map when the auto qos classify command is configured: policy-map AUTOQOS-SRND4-CLASSIFY-POLICY class AUTOQOS_MULTIENHANCED_CONF_CLASS set dscp af41 class AUTOQOS_BULK_DATA_CLASS set dscp af11 class AUTOQOS_TRANSACTION_CLASS set dscp af21 class AUTOQOS_SCAVANGER_CLASS set dscp cs1 class AUTOQOS_SIGNALING_CLASS set dscp cs3 class AUTOQOS_DEFAULT_CLASS set dscp default This is the policy map when the auto qos classify police command is configured: policy-map AUTOQOS-SRND4-CLASSIFY-POLICE-POLICY class AUTOQOS_MULTIENHANCED_CONF_CLASS set dscp af41 police 5000000 8000 exceed-action drop class AUTOQOS_BULK_DATA_CLASS set dscp af11 police 10000000 8000 exceed-action policed-dscp-transmit class AUTOQOS_TRANSACTION_CLASS set dscp af21 police 10000000 8000 exceed-action policed-dscp-transmit class AUTOQOS_SCAVANGER_CLASS set dscp cs1 police 10000000 8000 exceed-action drop class AUTOQOS_SIGNALING_CLASS set dscp cs3 police 32000 8000 exceed-action drop class AUTOQOS_DEFAULT_CLASS set dscp default police 10000000 8000 exceed-action policed-dscp-transmit Downloaded from www.Manualslib.com manuals search engine

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands auto qos classify Note The switch applies the auto-QoS-generated commands as if the commands were entered from the command-line interface (CLI). An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands. These actions occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the switch without saving the current configuration to memory. If the generated commands fail to be applied, the previous running configuration is restored. After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map. To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. Use the debug auto qos privileged EXEC command to enable auto-QoS debugging. For more information, see the debug auto qos command. To disable auto-QoS on a port, use the no auto qos trust interface configuration command. Only the auto-QoS-generated interface configuration commands for this port are removed. If this is the last port on which auto-QoS is enabled and you enter the no auto qos trust command, auto-QoS is considered disabled even though the auto-QoS-generated global configuration commands remain (to avoid disrupting traffic on other ports affected by the global configuration). You can use the no mls qos global configuration command to disable the auto-QoS-generated global configuration commands. With QoS disabled, there is no concept of trusted or untrusted ports because the packets are not modified. The CoS, DSCP, and IP precedence values in the packet are not changed.

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands auto qos trust Command Modes Interface configuration Command History Usage Guidelines Use this command to configure the QoS for trusted interfaces within the QoS domain. The QoS domain includes the switch, the network interior, and edge devices that can classify incoming traffic for QoS. Auto-QoS configures the switch for connectivity with a trusted interface. The QoS labels of incoming packets are trusted. For nonrouted ports, the CoS value of the incoming packets is trusted. For routed ports, the DSCP value of the incoming packet is trusted. To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS. If the port is configured with auto-QoS trust, it trusts all the packets on the port. If the packets are not marked with a DSCP or CoS value, default marking takes affect.

OL-21522-02 Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands auto qos trust Note The switch applies the auto-QoS-generated commands as if the commands were entered from the command-line interface (CLI). An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands. These actions occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the switch without saving the current configuration to memory. If the generated commands fail to be applied, the previous running configuration is restored. After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map. To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. Use the debug auto qos privileged EXEC command to enable auto-QoS debugging. For more information, see the debug auto qos command. To disable auto-QoS on a port, use the no auto qos trust interface configuration command. Only the auto-QoS-generated interface configuration commands for this port are removed. If this is the last port on which auto-QoS is enabled and you enter the no auto qos trust command, auto-QoS is considered disabled even though the auto-QoS-generated global configuration commands remain (to avoid disrupting traffic on other ports affected by the global configuration). You can use the no mls qos global configuration command to disable the auto-QoS-generated global configuration commands. With QoS disabled, there is no concept of trusted or untrusted ports because the packets are not modified (the CoS, DSCP, and IP precedence values in the packet are not changed).

An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands. These actions occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the switch without saving the current configuration to memory. If the generated commands fail to be applied, the previous running configuration is restored. If this is the first port on which you have enabled auto-QoS, the auto-QoS-generated global configuration commands are executed followed by the interface configuration commands. If you enable auto-QoS on another port, only the auto-QoS-generated interface configuration commands for that port are executed. When you enable the auto-QoS feature on the first port, these automatic actions occur: • QoS is globally enabled (mls qos global configuration command), and other global configuration commands are added. • When you enter the auto qos voip cisco-phone interface configuration command on a port at the edge of the network that is connected to a Cisco IP Phone, the switch enables the trusted boundary feature. The switch uses the Cisco Discovery Protocol (CDP) to detect the presence of a Cisco IP Phone. When a Cisco IP Phone is detected, the ingress classification on the port is set to trust the QoS label received in the packet. The switch also uses policing to determine whether a packet is in or out of profile and to specify the action on the packet. If the packet does not have a DSCP value of 24, 26, or 46 or is out of profile, the switch changes the DSCP value to 0. When a Cisco IP Phone is absent, the ingress classification is set to not trust the QoS label in the packet. The switch configures ingress and egress queues on the port according to the settings in Table 2-10 and Table 2-11. The policing is applied to those traffic matching the policy-map classification before the switch enables the trust boundary feature. • When you enter the auto qos voip cisco-softphone interface configuration command on a port at the edge of the network that is connected to a device running the Cisco SoftPhone, the switch uses policing to decide whether a packet is in or out of profile and to specify the action on the packet. If the packet does not have a DSCP value of 24, 26, or 46 or is out of profile, the switch changes the DSCP value to 0. The switch configures ingress and egress queues on the port according to the settings in Table 2-10 and Table 2-11. • When you enter the auto qos voip trust interface configuration command on a port connected to the network interior, the switch trusts the CoS value for nonrouted ports or the DSCP value for routed ports in ingress packets (the assumption is that traffic has already been classified by other edge devices). The switch configures the ingress and egress queues on the port according to the settings in Table 2-10 and Table 2-11. You can enable auto-QoS on static, dynamic-access, and voice VLAN access, and trunk ports. When enabling auto-QoS with a Cisco IP Phone on a routed port, you must assign a static IP address to the IP phone. Note When a device running Cisco SoftPhone is connected to a switch or routed port, the switch supports only one Cisco SoftPhone application per port. After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map. Downloaded from www.Manualslib.com manuals search engine

Syntax Description This command has no arguments or keywords. Defaults Enabled. Command Modes Global configuration Command History Usage Guidelines A switch in VM mode is a switch that has a different minor version number than the version on the switch stack. A switch in VM mode cannot join the switch stack as a fully functioning member. If the switch stack has an image that can be copied to a switch in VM mode, the auto-upgrade process automatically copies the image from a stack member to the switch in VM mode. The switch then exits VM mode, reboots, and joins the switch stack as a fully functioning member. The auto-upgrade process affects only switches in VM mode. It does not affect existing stack members.
