The list of interfaces where BFD MAD is enabled and their MAD IP addresses configured for MAD detection. display switchover state Any view Use the display switchover state command to display the master/slave switchover states of members of an IRF virtual device. display switchover state [ slot member-id ] [ { begin exclude include } regular-expression ] 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 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, which is a case-sensitive string of 1 to 256 characters. Display the master/slave switchover states of the master. <Sysname> display switchover state Master HA State to slot 2: Slave is absent. Master HA State to slot 3: Slave is absent. Master HA State to slot 4: Waiting batch backup request from slave. Master HA State to slot 5: Slave is absent. Master HA State to slot 6: Realtime backup to slave. Master HA State to slot 7: Realtime backup to slave. Master HA State to slot 8: Slave is absent. 8

12 Master HA State to slot 9: Slave is absent. Master HA State to slot 10: Slave is absent. The output shows that the following conditions are true in this example: The slave switches 2, 3, 5, 8, 9, and 10 are absent, which means that these switches are not in use. The master is waiting for the batch backup request from slave 4. Slaves 6 and 7 are performing real time backup. Table 6 Command output 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 (subordinate) whose slotnumber represents its member ID. The slave (subordinate) switch is transitioning to the master role. Display the master/slave switchover state of slave 6. <Sysname> display switchover state slot 6 Slave HA State: Receiving realtime data. The output shows that slave 6 is receiving real-time backup data. Table 7 Command output for a slave (subordinate) Field Slave HA State Waiting Indicates that this output information is generated by a slave (subordinate). Describes the master/slave switchover state of the slave (subordinate). The slave (subordinate) is ready, and is waiting to enter the batch backup state. irf auto-update enable Use the irf auto-update enable command to enable the automatic update of boot files for an IRF virtual device. Use the undo irf auto-update enable command to disable this function. By default, this function is enabled. After loading the master s boot file, a slave (subordinate) automatically configures the file as the boot file to be used at the next boot and reboots. The system boot file occupies a large memory space. Make sure that there is enough space on the storage device of the slave (subordinate). If the downloaded boot file and the local boot file have duplicate file names, the local file is overwritten. Make sure that no local file has the same name as the boot file to be downloaded. 9

13 irf auto-update enable undo irf auto-update enable System view None irf domain Enable the automatic upgrade of boot files for an IRF virtual device. [Sysname] irf auto-update enable Use the irf domain command to assign a domain ID for an IRF virtual device. Use the irf domain command to restore the default. By default, the domain ID of an IRF virtual device is 0. You may deploy multiple IRF virtual devices in one network for various networking applications. You can use domain IDs to differentiate these IRF virtual devices. irf domain domain-id undo irf domain System view domain-id: Domain ID assigned to an IRF virtual device, ranging from 0 to 4,294,967,295. Set the domain ID of the IRF virtual device to 30. [Sysname] irf domain 30 10

14 irf link-delay Use the irf link-delay command to set the delay time for the link layer to report a link-down event of an IRF virtual device. Use the undo irf link-delay command to restore the default. By default, the link layer is not enabled to report a link-down event of an IRF virtual device. irf link-delay interval undo irf link-delay System view interval: Delay time for the link layer to report a link-down event of an IRF virtual device, ranging from 200 to 2000 milliseconds. Set the delay time for the link layer to report a link-down event of the current IRF virtual device to 300 milliseconds. [Sysname] irf link-delay 300 irf mac-address persistent Use the irf mac-address persistent command to enable the IRF virtual device 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 virtual device to change its bridge MAC address as soon as the master leaves. By default, the IRF virtual device preserves its bridge MAC address for six minutes after the master leaves. 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 virtual device uses the bridge MAC address of the newly elected master as its bridge MAC address. Preserve permanently: Whether or not the master leaves the IRF virtual device, the bridge MAC address of the IRF virtual device remains unchanged. Not preserved: As soon as the master leaves, the IRF virtual device 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 virtual device to change as soon as the master leaves. 11

15 irf mac-address persistent { always timer } undo irf mac-address persistent System view always: Enables the IRF virtual device to preserve its bridge MAC address permanently, even after the master leaves. timer: Enables the IRF virtual device to preserve its bridge MAC address for six minutes after the master leaves. Configure the bridge MAC address of the IRF virtual device to be preserved permanently. [Sysname] irf mac-address persistent always irf member description Use the irf member description command to configure the description of a specified member switch. Use the undo irf member description command to restore the default. By default, no description is configured for a member switch. irf member member-id description text undo irf member member-id description System view member-id: ID of an IRF member switch. text: of the member switch, which is a string of 1 to 127 characters. Configure the description of the IRF member switch 1. [Sysname] irf member 1 description F1Num001 12

16 irf member priority Use the irf member priority command to specify a priority for a 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 is more likely to preserve its ID in a member ID collision. irf member member-id priority priority undo irf member member-id priority System view member-id: ID of an IRF member switch. priority: Priority value, ranging from 1 to 32. Specify a priority for the local switch. <Sysname> display irf Switch Role Priority CPU-Mac +1 Slave f-e Slave 1 000f-e *3 Master f-e Slave f-e * indicates the device is the master. + indicates the device through which the user logs in. The Bridge MAC of the IRF is: 000f-e Auto upgrade : yes Mac persistent : always Domain ID : 0 The output shows that the member ID of the local switch is 3. 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 Use the irf member renumber command to change the member ID of a switch in the IRF virtual device. Use the undo irf member renumber command to remove the configuration. By default, the IRF member ID of a switch is 1. After you change the IRF member ID of a switch, you must reboot the switch to have the setting take effect. For an IRF virtual device, member IDs are not only used to identify devices but also 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 virtual device. 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 to the IRF virtual device 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 virtual device automatically assigns the smallest unused member ID to the new member. irf member member-id renumber new-member-id undo irf member member-id renumber System view member-id: Specifies the ID of an IRF member switch, ranging from 1 to 10. new-member-id: Assigns a new ID for the IRF member switch, ranging from 1 to 10. Set the member ID of the local switch to 3 (currently, the member ID is 1). <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 14

18 Warning: Renumbering the switch number may result in configuration change or loss. Continue?[Y/N]y 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 Use the irf switch-to command to redirect to the specified slave (subordinate) so that you can directly access the slave (subordinate). When you access an IRF virtual device, you actually log into 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 (subordinate), which is the same as directly logging into the slave (subordinate). The operation interface of the access terminal switches from the console of the master to that of the slave (subordinate), and the system displays the user view of the slave (subordinate). 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 enter at the terminal are forwarded to the specified slave (subordinate) without being processed by the local switch. You can execute the following commands on a slave (subordinate): display quit return system-view debugging terminal debugging terminal trapping terminal logging To return to the console of the master, execute the quit command. The master is reactivated and ready for outputting information. You cannot redirect to the master of the IRF virtual device by using the irf switch-to command. irf switch-to member-id System view 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 virtual device. Redirect to member 2. 15

19 irf-port [Sysname] irf switch-to 2 <Sysname-Slave#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 displays the 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. Before establishing an IRF, you must enter IRF port view and bind physical IRF ports to this IRF port. The IRF port is then available for the IRF virtual device. Related commands: port group interface. irf-port member-id/port-number undo irf-port member-id/port-number System view 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. 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 3/0/25. [Sysname] interface ten-gigabitethernet 3/0/25 [Sysname-Ten-GigabitEthernet3/0/25] shutdown [Sysname-Ten-GigabitEthernet3/0/25] quit [Sysname] irf-port 3/1 [Sysname-irf-port3/1] port group interface ten-gigabitethernet 3/0/25 [Sysname-irf-port3/1] quit [Sysname] interface ten-gigabitethernet 3/0/25 [Sysname-Ten-GigabitEthernet3/0/25] undo shutdown irf-port load-sharing mode (system view) 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: 16

20 The G Switch with 1 Interface Slot (JC105A), G TAA Switch with 1 Interface Slot (JG258A), G-PoE+ Switch with 1 Interface Slot (JC104A), and G-PoE+ TAA Switch with 1 Interface Slot (JG257A) use the inbound port number as the hash key. Other models of the HP 5800 and 5820X switches use the combination of the source and destination MAC addresses as the hash key when processing Layer 2 packets. Other models of the HP 5800 and 5820X switches 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 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 new configuration overwrites the former one 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 a combination of source and destination MAC addresses, you must execute the irf-port loadsharing mode source-mac command, and then reconfigure 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 one of the following three choices as the hash key: Any one of the following, by itself: the source IP address, the destination IP address, the source MAC address, or the destination MAC address. The combination of the source and the destination IP addresses. The combination of the source and the destination MAC addresses. irf-port load-sharing mode { destination-ip destination-mac source-ip source-mac } * undo irf-port load-sharing mode System view 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. 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 17

21 irf-port load-sharing mode (IRF port view) 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 G Switch with 1 Interface Slot (JC105A), G TAA Switch with 1 Interface Slot (JG258A), G-PoE+ Switch with 1 Interface Slot (JC104A), and G-PoE+ TAA Switch with 1 Interface Slot (JG257A) use the inbound port number as the hash key. Other models of the HP 5800 and 5820X switches use the combination of the source and destination MAC addresses as the hash key when processing Layer 2 packets. Other models of the HP 5800 and 5820X switches 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 new configuration overwrites the former one 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 reconfigure 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 one of the following three choices as the hash key: Any one of the following, by itself: the source IP address, the destination IP address, the source MAC address, or the destination MAC address. The combination of the source and the destination IP addresses.

[Sysname] irf-port 1/1 [Sysname-irf-port 1/1] irf-port load-sharing mode destination-mac irf-port-configuration active 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 ports to an IRF port whose link state is DIS or DOWN, you must execute the irf-port-configuration active command to establish the IRF virtual device. You can use the display irf topology command to display this configuration. Activating IRF port configurations may cause IRF virtual device merge and device reboot. To avoid configuration loss, follow these steps to set the member ID for a device: 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 you execute 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. irf-port-configuration active System view None 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 must bind it to a physical IRF port. Shut down the physical IRF port before the binding, and activate it after the binding. [Sysname] interface ten-gigabitethernet 1/0/27 19

Activate configurations on the IRF port [Sysname] irf-port-configuration active mad arp enable Use the mad arp enable command to enable ARP MAD to detect the IRF virtual device for multi-active collisions. Use the undo mad arp enable command to disable ARP MAD. By default, ARP MAD is disabled. mad arp enable undo mad arp enable VLAN interface view None Enable ARP MAD on VLAN-interface 3.

24 mad bfd enable Use the mad bfd enable command to enable BFD MAD to detect multiple IRF virtual devices with the same IP address on the network. Use the undo mad bfd enable command to disable BFD MAD. By default, BFD MAD is disabled. Do not configure any services (such as ARP) on a BFD MAD-enabled Layer 3 interface. Doing so can cause both the configured services and BFD MAD to work incorrectly. Do not bind a BFD MAD-enabled Layer 3 interface to any VPN or enable the spanning tree feature on the ports in the VLAN that corresponds to this interface. Doing so can cause BFD MAD to work incorrectly. Do not enable BFD MAD detection on VLAN-interface 1. Related commands: mad ip address. mad bfd enable undo mad bfd enable VLAN interface view None Enable BFD MAD on VLAN-interface 3. [Sysname] interface vlan-interface 3 [Sysname-Vlan-interface3] mad bfd enable mad enable Use the mad enable command to enable LACP MAD to detect the IRF virtual device for multi-active collisions. Use the undo mad enable command to disable LACP MAD. By default, LACP MAD is disabled. This command takes effect only on dynamic aggregate interfaces. mad enable undo mad enable 21

25 Aggregate interface view None Enable LACP MAD on LACP-enabled dynamic Layer 2 aggregate interface 1. [Sysname] interface bridge-aggregation 1 [Sysname-Bridge-Aggregation1] mad enable mad exclude interface Use the mad exclude interface command to configure a service port to not shut down when the IRF virtual device transitions to 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 virtual device shut down when the IRF virtual device transitions to recovery state. When a MAD-enabled IRF virtual device is detected as partitioned into two or more identical active IRF virtual devices, all IRF virtual devices except 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 virtual devices. All of the service ports are shut down except the IRF ports and those manually configured not to shut down. When the member switches reboot to join the recovered IRF virtual device, the ports that were shut down come up. Use the mad restore command to manually recover the members and disabled ports. mad exclude interface interface-type interface-number undo mad exclude interface interface-type interface-number System view interface-type interface-number: Specifies a port by its type and number. Specify GigabitEthernet 2/0/1 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 22

26 mad ip address Use the mad ip address command to configure the MAD IP address for the specified member switch. Use the undo mad ip address command to delete the configured MAD IP address. By default, no MAD IP address is configured for any interface. BFD MAD is implemented by using the BFD protocol. To configure BFD MAD detection, configure a MAD IP address on a BFD-enabled Layer 3 interface for each member switch. This MAD address identifies the member during BFD MAD detection. The MAD IP addresses assigned to the member switches must belong to the same network segment. When the IRF virtual device operates normally, only the MAD IP address of the master is effective, and the BFD session is down. When the IRF virtual device partitions, the MAD IP addresses of the masters in different IRF virtual devices become effective to activate the BFD sessions to detect multi-active IRF virtual device collision. An interface used for BFD MAD must be dedicated. Do not configure any other services on an interface that has BFD MAD enabled. Otherwise, both the configured services and the BFD MAD detection function may be affected. You can use the mad ip address command to assign a MAD IP address to an interface that is used exclusively for BFD MAD detection. You cannot configure other IP addresses for BFD MAD detection, including a common IP address or VRRP virtual IP address configured with the ip address command. Related commands: mad bfd enable. mad ip address ip-address { mask mask-length } member member-id undo mad ip address ip-address { mask mask-length } member member-id VLAN interface view ip-address: Specifies an IP address in dotted decimal notation for the Layer 3 interface. mask: Specifies a subnet mask in decimal dotted notation. mask-length: Specifies the subnet mask length, which is the number of successive 1s in the mask. The value ranges from 0 to 32. member member-id: Specifies the ID of an IRF member switch. Configure the MAD IP address for VLAN-interface 3 on member 1. [Sysname] interface vlan-interface 3 [Sysname-Vlan-interface3] mad ip address member 1 Configure the MAD IP address for VLAN-interface 3 on member 2. 23

27 [Sysname-Vlan-interface3] mad ip address member 2 mad restore Use the mad restore command to restore the member switches of the IRF virtual device in recovery state to normal state. An IRF link failure triggers IRF virtual device partition and causes a multi-active collision. In this case, one IRF virtual device can keep the active state, and other IRF virtual devices change into recovery state. In recovery state, the IRF virtual device cannot forward packets. If the IRF virtual device in the recovery state fails before the failure is recovered, repair both the failed IRF virtual device and the failed IRF link. The collided IRF virtual devices are merged into one, and the failure is recovered. If the IRF virtual device in the active state fails before the failure is recovered, enable the IRF virtual device in the recovery state at the CLI to make it take over the active IRF virtual device and protect the services from being affected. mad restore System view None Restore IRF virtual devices in recovery state to the normal state. [Sysname] mad restore This command will restore the device from multi-active conflict state. Continue? [Y/N]:Y Restoring from multi-active conflict state, please wait... port group interface 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 cancel an IRF port binding. By default, no physical port is bound to any IRF port. You can bind up to four physical ports to an IRF port. The operating mode configured is effective only for a physical IRF port. Two directly connected physical IRF ports, or the physical IRF ports bound to the same IRF port, must be configured to work in the same operating mode. For VPLS networking, the operating mode of the physical IRF ports should be set to enhanced. 24

28 In IRF mode: Before binding a physical port to an IRF port, shut down the physical port by using the shutdown command, and then execute the port group interface command. Then, bring up the physical port by using the undo shutdown command. The physical port can then establish an IRF connection as a physical IRF port. In standalone mode: You can execute the port group interface command directly and do not need to shut down the physical port. In IRF mode: Before canceling the binding between a physical port and an IRF port, you must first shut down the physical port by using the shutdown command, and then execute the undo port group interface command. Then, bring up the physical port by using the undo shutdown command. The physical port can then forward packets. In standalone mode: You can execute the undo port group interface command directly and do not need to shut down the physical port. 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 is not plugged in, the binding between the two ports still exists. To cancel the binding between the two ports, use the undo port group interface command. port group interface interface-type interface-number [ mode { enhanced normal } ] undo port group interface interface-name IRF port view interface-type interface-number: Specifies port type and port number. 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. If no operating mode is specified, an IRF physical port works in enhanced mode by default. enhanced: Sets the physical IRF port to work in enhanced mode. normal: Sets the physical IRF port to work in normal mode.
