The aggregate interface where LACP MAD is enabled. display switchover state display switchover state [ slot member-id ] [ { begin exclude include } regular-expression ] Any view 1: Monitor level slot member-id: Specifies the ID of an IRF member switch. With this argument, the command displays the master/slave switchover state of the specified member. Without this argument, the command displays the master/slave switchover state of the master. : Filters command output by specifying a regular expression. For more information about regular expressions, see the Fundamentals Configuration Guide. begin: Displays the first line that matches the specified regular expression and all lines that follow. exclude: Displays all lines that do not match the specified regular expression. include: Displays all lines that match the specified regular expression. regular-expression: Specifies a regular expression, case-sensitive string of 1 to 256 characters. Use the display switchover state command to display the master/slave switchover states of members of an IRF fabric. 8

12 # Display the master/slave switchover states of the master. <Sysname> display switchover state Master HA State to slot 2: Realtime backup to slave. Master HA State to slot 3: Slave is absent. Master HA State to slot 4: Waiting batch backup request from slave. The output shows that the slave switches 3 is absent, or not in use, the master is waiting for the batch backup request from slave 4, and the slave switches 2 is performing real-time backup. The output shows the following conditions: Slaves 3 is absent, which means that the switch is not in use. The master is waiting for the batch backup request from slave 4. Slaves 2 is performing real time backup. Table 6 Output description for the master Field Master HA State to slot slot-number Data smooth Indicates that this output information is generated by the master. Describes the master/slave switchover state between the master and the slave whose slot-number represents its member ID. The slave switch is transitioning to the master role. # Display the master/slave switchover state of slave 3. <Sysname> display switchover state slot 3 Slave HA State: Receiving realtime data. The output shows that slave 3 is receiving real time backup data. Table 7 Output description for a slave Field Slave HA State Waiting Indicates that this output information is generated by a slave. Describes the master/slave switchover state of the slave. The slave is ready, and is waiting to enter the batch backup state. irf auto-update enable irf auto-update enable undo irf auto-update enable System view 3: Manage level 9

13 None Use the irf auto-update enable command to automatically synchronize the system software image of the master switch to the switch you are adding to the IRF fabric. Use the undo irf auto-update enable command to disable this function. By default, this function is enabled. IMPORTANT: irf domain After loading the master s system software, a slave automatically configures the file as the system software to be used at the next boot and reboots. Check that the switch has efficient space for the new system software image. If the downloaded system software image and the local system software image have duplicate file names, the local file will be overwritten. Verify that there is not any local file having the same name with the system software image to be downloaded. # Enable the automatic system software updating function on the IRF fabric. [Sysname] irf auto-update enable irf domain domain-id undo irf domain System view 3: Manage level domain-id: Assigns a domain ID to the IRF fabric, ranging from 0 to Use the irf domain command to assign a domain ID for an IRF fabric. Use the irf domain command to restore the default. By default, the domain ID of an IRF fabric is 0. NOTE: You may deploy multiple IRF fabrics in one network for various networking applications. You can use domain IDs to differentiate these IRF fabrics. # Set the domain ID of the IRF fabric to

14 [Sysname] irf domain 30 irf link-delay irf link-delay interval undo irf link-delay System view 3: Manage level interval: Delay time for the link layer to report a link-down event of an IRF fabric, ranging from 200 to 2000 milliseconds. Use the irf link-delay command to set the delay time for the link layer to report a link-down event of an IRF fabric. Use the undo irf link-delay command to restore the default. You can avoid link flapping causing frequent IRF splits and merges during switch reconfiguration by configuring the IRF ports to delay reporting link down events. The default delay for reporting an IRF link down event is 250 milliseconds. # Set the delay time for the link layer to report a link-down event of the current IRF fabric to 300 milliseconds. [Sysname] irf link-delay 300 irf mac-address persistent irf mac-address persistent { always timer } undo irf mac-address persistent System view 3: Manage level always: Enables the IRF fabric to preserve its bridge MAC address permanently even after the master leaves. timer: Enables the IRF fabric to preserve its bridge MAC address for six minutes after the master leaves. 11

15 Use the irf mac-address persistent command to enable the IRF fabric to preserve its bridge MAC address for a certain period after the master leaves. Use the undo irf mac-address persistent command to enable the IRF fabric to change its bridge MAC address as soon as the master leaves. By default, the IRF fabric preserves its bridge MAC address for six minutes after the master leaves. NOTE: Preserve for six minutes: When the master leaves, the bridge MAC address does not change within six minutes. If the master does not come back when the preservation time expires, the IRF fabric uses the bridge MAC address of the newly elected master as its bridge MAC address. Preserve permanently: Whether the master leaves the IRF fabric or not, the bridge MAC address of the IRF fabric remains unchanged. Not preserved: As soon as the master leaves, the IRF fabric uses the bridge MAC address of the newly elected master as its bridge MAC address. When you plan a network that uses ARP MAD and MSTP, use the undo irf mac-address persistent command to configure the bridge MAC address of the IRF fabric to change as soon as the master leaves. # Configure the bridge MAC address of the IRF fabric to be preserved permanently. [Sysname] irf mac-address persistent always irf member description irf member member-id description text undo irf member member-id description System view 3: Manage level member-id: ID of an IRF member switch. text: of the member switch, a string of 1 to 127 characters. Use the irf member description command to configure a description for an IRF member switch. Use the undo irf member description command to restore the default. By default, no description is configured for any IRF member switch. # Configure a description for IRF member switch 1. [Sysname] irf member 1 description F1Num001 12

16 irf member priority irf member member-id priority priority undo irf member member-id priority System view 3: Manage level member-id: ID of an IRF member switch. priority: Priority value, ranging from 1 to 32. Use the irf member priority command to specify a priority for an IRF member switch. Use the undo irf member priority command to restore the default. By default, the priority of a member switch is 1. The greater the priority value, the higher the priority. A member with a higher priority is more likely to be the master, and more likely to preserve its ID in a member ID collision. # Specify a priority for the local switch. <Sysname> display irf Switch Role Priority CPU-Mac *1 Slave 29 00e0-fc Slave 1 00e0-fc Master 32 00e0-fc Slave 30 00e0-fc * indicates the device is the master. + indicates the device through which the user logs in. The Bridge MAC of the IRF is: 00e0-fc Auto upgrade Mac persistent : yes : always Domain ID : 0 The output shows that the member ID of the local switch is 3, and you can specify a priority for the local switch by providing its member ID. [Sysname] irf member 3 priority 16 # Specify a priority for member 2 in the current IRF. [Sysname] irf member 2 priority 32 13

17 irf member renumber irf member member-id renumber new-member-id undo irf member member-id renumber System view 3: Manage level member-id: Specifies the ID of an IRF member switch, which ranges from 1 to 4. new-member-id: Assigns a new ID for the IRF member switch, which ranges from 1 to 4. Use the irf member renumber command to change the member ID of a switch in the IRF fabric. Use the undo irf member renumber command to remove the configuration. By default, the IRF member ID of a switch is 1. NOTE: This setting takes effect at the reboot of the switch. For an IRF fabric, member IDs are not only used to identify devices, but also used to configure IRF ports and member priorities. Therefore, modifying a member ID may cause switch configuration change or even loss. Modify member IDs with caution. For example, three members (of the same switch model) with the member IDs of 1, 2 and 3 belong to an IRF fabric. Assume that each member has several ports: change the member ID of switch 2 to 3, change that of switch 3 to 2, reboot both switches, and add them into the IRF fabric again. Then switch 2 uses the original port configurations of switch 3, and switch 3 uses those of switch 2. When the newly added switch and another member have duplicated member IDs, the existing member can preserve its ID, and the IRF fabric automatically assigns the smallest unused member ID to the new member. # Set the member ID of the local switch (the member ID is 1) to 3. <Sysname> display irf [Sysname] irf member 1 renumber 3 Warning: Renumbering the switch number may result in configuration change or loss. Continue?[Y/N]:Y # Change the IRF member ID of a switch from 2 to 4. [Sysname] irf member 2 renumber 4 Warning: Renumbering the switch number may result in configuration change or loss. Continue?[Y/N]y To cancel the above configuration and restore the original member ID of the switch, execute the following command: [Sysname] undo irf member 2 renumber Warning: Renumbering the switch number may result in configuration change or loss. Continue?[Y/N]y 14

18 To change the IRF member ID to 2 after you reboot the switch, you must use the irf member 4 renumber 2 command. irf switch-to irf switch-to member-id System view 3: Manage level member-id: ID of an IRF member switch. The member-id argument in this command cannot be the member ID of the master. The value range depends on the current number of members and their member IDs in the IRF fabric. Use the irf switch-to command to redirect to the specified slave so that you can directly access the slave. When you access an IRF fabric, you actually log in to the master. The console of the master is displayed as the operation interface of the access terminal. After you execute this command, you are redirected to the specified slave, which is equal to directly logging in to the slave. The operation interface of the access terminal switches from the console of the master to that of the slave, and the system enters the user view of the slave and the command prompt is changed to <Sysname-Slave#X>, where X is the member ID of the device, for example, <Sysname-Slave#2>. After this command is executed, the instructions that you input at the terminal will be forwarded to the specified slave, without being processed by the local switch. You can execute the following commands on a slave: display quit return system-view debugging terminal debugging terminal logging terminal trapping To return to the console of the master, execute the quit command. The master will be reactivated and ready for outputting information. You cannot redirect to the master of the IRF fabric with the irf switch-to command. # Redirect to member 2. [Sysname] irf switch-to 2 <Sysname-Slave#2> 15

19 irf-port irf-port member-id/port-number undo irf-port member-id/port-number System view 3: Manage level member-id/port-number: IRF port number, where member-id represents the ID of the IRF member switch. The port-number argument specifies the port number, and the value can be either 1 or 2. Use the irf-port command to create an IRF port and enter IRF port view. If the IRF port is already created, this command enters IRF port view. Use the undo irf-port command to delete the specified IRF port. By default, no IRF port is created on the switch. NOTE: Before establishing an IRF, you must enter IRF port view, and bind physical IRF port(s) to this IRF port, and then the IRF port will be available for the IRF fabric. Related commands: port group interface. # Create IRF port IRF-port 1 for the device with the member ID of 3, and bind this port to physical IRF port Ten-GigabitEthernet 3/1/1.

20 2: System level destination-ip: Uses the destination IP address of packets as the hash key. destination-mac: Uses the destination MAC address of packets as the hash key. source-ip: Uses the source IP address of packets as the hash key. source-mac: Uses the source MAC address of packets as the hash key. Use the irf-port load-sharing mode command to configure global IRF port load sharing mode. Use the undo irf-port load-sharing mode command to restore the default. By default, the A5120 EI switches use the combination of source and destination MAC addresses as the hash key when processing Layer 2 packets, and use the combination of source and destination IP addresses when processing Layer 3 packets. After you specify a load sharing mode, the switch extracts the corresponding field (IP address or MAC address) in a packet or the inbound port number based on the selected mode. The switch performs the hash function on the address or port number and on the number of physical IRF ports in an aggregate IRF port. Then, the switch determines which physical IRF port sends out the packet. For this command, the latter configuration will overwrite the former instead of as a supplement. For example, the current load sharing mode uses the destination MAC address as the hash key. If you want to change it as the combination of source and destination MAC addresses, you must execute the irf-port load-sharing mode source-mac command, and re-configure the load sharing mode by executing the irfport load-sharing mode destination-mac source-mac command. When you configure IRF port load sharing mode in system view, you can specify the following combinations as the hash key: Any of the source IP address, destination IP address, source MAC address, or destination MAC address separately. The combination of the source and the destination IP addresses. The combination of the source and the destination MAC addresses. # Configure the global IRF port load sharing mode, using the destination MAC address of packets as the hash key. [Sysname] irf-port load-sharing mode destination-mac irf-port load-sharing mode (IRF port view) irf-port load-sharing mode { destination-ip destination-mac source-ip source-mac } * undo irf-port load-sharing mode IRF port view 17

21 2: System level destination-ip: Uses the destination IP address of packets as the hash key. destination-mac: Uses the destination MAC address of packets as the hash key. source-ip: Uses the source IP address of packets as the hash key. source-mac: Uses the source MAC address of packets as the hash key. Use the irf-port load-sharing mode command to configure the load sharing mode for an IRF port. Use the undo irf-port load-sharing mode command to restore the default. By default, the A5120 EI switches use the combination of the source and destination MAC addresses as the hash key when processing Layer 2 packets, and use the combination of the source and destination IP addresses when processing Layer 3 packets. After you specify a load sharing mode, the switch extracts the corresponding field (IP address or MAC address) in a packet or the inbound port number based on the selected mode. The switch performs the hash function on the address or port number and the number of physical IRF ports in an aggregate IRF port. Then, the switch determines which physical IRF port sends out the packet. For this command, the latter configuration will overwrite the former instead of creating a supplement. For example, the current load sharing mode uses the destination MAC address as the hash key. If you want to change it to the combination of source and destination MAC addresses, you must execute the irf-port load-sharing mode source-mac command, and re-configure the load sharing mode by executing the irfport load-sharing mode destination-mac source-mac command. When configuring IRF port load sharing mode in system view, you can specify the following combinations as the hash key: Any of the source IP address, destination IP address, source MAC address or destination MAC address separately. The combination of the source and the destination IP addresses. The combination of the source and the destination MAC addresses as the hash key. # Configure the load sharing mode for IRF port 1/1, using the destination MAC address of packets as the hash key. [Sysname] irf-port 1/1 [Sysname-irf-port 1/1] irf-port load-sharing mode destination-mac irf-port-configuration active irf-port-configuration active System view 18

22 3: Manage level None Use the irf-port-configuration active command to activate configurations on all IRF ports on the switch. If you connect the IRF links and bind physical IRF port(s) to an IRF port whose link state is DIS or DOWN, you must execute the irf-port-configuration active command to establish the IRF fabric. You can use the display irf topology command to display this configuration. Activating IRF port configurations may cause IRF fabric merge and device reboot. To avoid configuration loss, set the member ID for a device in the following way: 1. Plan the network and member IDs in advance. Determine the number of IRF ports to be created, and which physical IRF ports will be used for IRF establishment. 2. Modify member IDs for switches. (The modifications of member IDs become effective after switch reboot, so modify member IDs before executing the irf-port-configuration active command.) 3. Connect SFP+ cables or fibers and make sure that the physical IRF ports are well connected. 4. Create IRF ports. 5. Bind physical IRF ports to IRF ports. 6. Save the current configurations to the configuration file for the next startup. 7. Activate configurations on all IRF ports. After the system starts up, when you bind a physical IRF port to an IRF port through the configuration file, or add a new physical port, the configurations on IRF ports are activated automatically, so you do not need to execute this command again. # Activate configurations on an IRF port with the DIS link. The link state of the IRF port indicates that the port has not been bound with any physical IRF port. Therefore, you need to bind it to a physical IRF port. Shut down the physical IRF port before the binding and activate it after the binding.

Use the mad exclude interface command to configure a service port not to shut down when the IRF fabric transitions to the recovery state on detection of a multi-active collision. Use the undo mad exclude interface command to restore the default. By default, all service ports of an IRF fabric shut down when the IRF fabric transitions to the recovery state. NOTE: When a MAD-enabled IRF fabric is detected as partitioned into two or more identical active IRF fabrics, all IRF fabrics but the one with the lowest master ID are placed in the recovery state to stop forwarding traffic and to ensure the uniqueness of the IRF fabrics. All of the service ports are shut down but the IRF ports and the ports that are manually configured not to shut down. When the member switches reboot to join the recovered IRF fabric, the ports that were shut down come up. Use the mad restore command to manually recover the members and disabled ports. # Specify GigabitEthernet2/0/1 as the reserved port, which will not be disabled when the switch is in the recovery state. [Sysname] mad exclude interface gigabitethernet 2/0/1 21

25 mad restore mad restore System view 3: Manage level None Use the mad restore command to recover the member switches of the IRF fabric in recovery state to the normal state. NOTE: An IRF link failure triggers IRF fabric partition and causes a multi-active collision. In this case, one IRF fabric can keep the active state and other IRF fabrics change into recovery state. In this state, the IRF fabric cannot forward packets. If the IRF fabric in the recovery state fails before the failure is recovered, repair both the failed IRF fabric and the failed IRF link. The collided IRF fabrics will merge into one and the failure will be recovered. If the IRF fabric in the active state fails before the failure is recovered, enable the IRF fabric in the recovery state at the CLI to make it take over the active IRF fabric and protect the services from being affected. # Restore IRF fabrics in recovery state to the normal state. [Sysname] mad restore This command will restore the device from multi-active conflict state. Continue?

26 interface-name: Interface name, in the format of interface-typeinterface-number. No space is allowed between the interface-type and interface-number arguments. mode: Sets the operating mode of the physical IRF port when the physical IRF port is bound to an IRF port. enhanced: Sets the physical IRF port to work in the enhanced mode. This keyword is not available now. normal: Sets the physical IRF port to work in the normal mode. Use the port group interface command to bind a physical port to an IRF port. The IRF port is activated when you bind the first physical port to it. Use the undo port group interface command to remove an IRF port binding. By default, no physical port is bound to any IRF port. NOTE: You can bind up to two physical ports to an IRF port, and these two physical ports must be located on the same expansion interface module. Before binding a physical port to an IRF port, shut down the physical port with the shutdown command, and then execute the port group interface command. Then, bring up the physical port with the undo shutdown command, and the physical port can establish an IRF connection as a physical IRF port. Before canceling the binding between a physical port and an IRF port, you must first shut down the physical port with the shutdown command, and then execute the undo port group interface command. After that, bring up the physical port with the undo shutdown command, and then the physical port can forward packets. When you configure this command, if the physical IRF port that is already bound to the IRF port does not exist because the interface card has been removed, the binding between the two ports still exists. To remove the binding between the two ports, use the undo port group interface command. # Bind physical IRF port Ten-GigabitEthernet 3/1/1 on member 3 to IRF port 1.
