IRF configuration commands chassis convert mode irf Use chassis convert mode irf to enable IRF mode. Use undo chassis convert mode to restore standalone mode. Syntax chassis convert mode irf undo chassis convert mode Default The device operates in standalone mode. Views System view Predefined user roles network-admin mdc-admin Usage guidelines To set up an IRF fabric, place all its member devices in IRF mode after configuring their member IDs, priorities, and IRF port settings.
The device will switch to stand-alone mode and reboot. You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in stand-alone mode? [Y/N]:y Please wait... Saving the converted configuration file to the main board succeeded. Chassis 2 Slot 1: Saving the converted configuration file succeeded.
Field Description Role of the MPU in the IRF fabric: Role • Standby—Standby MPU for the global active MPU. • Master—Global active MPU. • Loading—Standby MPU for the global active MPU.

Syntax display mad [ verbose ] Views Any view Predefined user roles network-admin network-operator mdc-admin mdc-operator Parameters verbose: Displays detailed MAD information. If this keyword is not provided, the command only displays whether a MAD mechanism is enabled. Examples # Display brief MAD information. display mad MAD ARP disabled. MAD ND disabled. MAD LACP enabled. MAD BFD disabled. # Display detailed MAD information.
Table 6 Command output Field Description MAD ARP disabled. ARP MAD is not supported in this software version. It is reserved for future support. MAD ND disabled. ND MAD is not supported in this software version. It is reserved for future support. MAD status: • Detect—The IRF fabric is integrated. • Recovery—The IRF fabric is in Recovery state.
This command is available in IRF mode. When the operating mode is changed to standalone, the configuration of this command is lost, regardless of whether you have saved the configuration. The IRF auto merge function takes effect for an IRF merge that occurs when the IRF link recovers from a link failure, or when you connect the IRF physical ports of the member devices. It does not take effect for the IRF merge that occurs when you bind a physical port to an IRF port in IRF mode.
• The storage space of the device you are adding to the IRF fabric is sufficient for saving the new software images. • The information center outputs the software auto-update status to configuration terminals, which can prevent the action of rebooting or swapping MPUs during the software auto-update process in a multi-user environment. For more information about the information center, see Network Management and Monitoring Configuration Guide.
In an MDC environment, the irf domain command is available only on the default MDC, but the mad enable command is available on all MDCs. If you change the IRF domain ID in one MDC, the IRF domain IDs in all other MDCs change automatically. Examples # Set the IRF domain ID to 30. system-view [Sysname] irf domain 30 irf link-delay Use irf link-delay to set a delay for the IRF ports to report a link down event. Use undo irf link-delay to restore the default.
Examples # Set the IRF link down report delay to 300 milliseconds. system-view [Sysname] irf link-delay 300 irf mac-address persistent Use irf mac-address persistent to configure IRF bridge MAC persistence. Use undo irf mac-address persistent to enable the IRF fabric to change its bridge MAC address as soon as the master leaves.
• TRILL is configured. Retain the IRF bridge MAC address for TRILL to maintain a correct network topology. • VRRP load balancing is used. For more information about VRRP, see High Availability Configuration Guide. If two IRF fabrics have the same bridge MAC address, they cannot merge. Examples # Enable the IRF bridge MAC address to be permanent. system-view [Sysname] irf mac-address persistent always irf member Use irf member to assign a member ID to the device in standalone mode.
irf member description Use irf member description to configure a description for an IRF member. Use undo irf member description to restore the default. Syntax irf member member-id description text undo irf member member-id description Default No description is configured for any IRF member. Views System view Predefined user roles network-admin mdc-admin Parameters member-id: Specifies the ID of an IRF member, in the range of 1 to 4.
Predefined user roles network-admin mdc-admin Parameters member-id: Specifies an IRF member ID in the range of 1 to 4. priority: Sets priority in the range of 1 to 32. The greater the priority value, the higher the priority. A member with higher priority is more likely to be the master. Usage guidelines Change member priority assignment to affect the maser election result. This command is available in IRF mode.
Usage guidelines CAUTION: In IRF mode, an IRF member ID change can invalidate member ID-related settings, including interface and file path settings, and cause data loss. Be sure you fully understand its impact on your live network. The new IRF member ID, including the one set by using the undo irf member renumber command, takes effect after you reboot the member device. To cancel the change before you reboot the member device, use the undo irf member renumber command.
Usage guidelines Member priority is used for role election. The greater the priority value, the higher the priority. A member with higher priority is more likely to be the master. The member priority configured in standalone mode takes effect after you enable IRF mode. To change the member priority of a device in IRF mode, use the irf member member-id priority priority command. The new priority setting takes effect at the next master election, but it does not trigger master election.
Usage guidelines The global IRF link load sharing mode applies to all IRF ports in the IRF fabric. You can configure the global IRF link load sharing mode to include a combination of multiple criteria for making traffic distribution decisions. For example, criteria could include source MAC address and IP address. The device displays an error message if it does not support a criterion combination. If you configure the global load sharing mode multiple times, the most recent configuration takes effect.
You can configure an IRF port-specific load sharing mode to include a combination of multiple criteria for making traffic distribution decisions. For example, criteria could include source MAC address and IP address. The device displays an error message if it does not support a criterion combination. If you configure the port-specific load sharing mode multiple times on an IRF port, the most recent configuration takes effect. An IRF port preferentially uses the port-specific load sharing mode.
irf-port port-number Use irf-port port-number to enter IRF port view in standalone mode. Use undo irf-port port-number to remove all port bindings on an IRF port in standalone mode. Syntax irf-port port-number undo irf-port port-number Views System view Predefined user roles network-admin mdc-admin Parameters port-number: Specifies an IRF port number, which must be 1 or 2.
The system activates the IRF port settings automatically in the following situations: • The configuration file that the device starts with contains IRF port bindings. • You are binding physical ports to an IRF port in up state. Examples To configure and activate IRF port 1/2: # Bind Ten-GigabitEthernet 1/1/0/27 to it.
Predefined user roles network-admin mdc-admin Usage guidelines You cannot use BFD MAD with LACP MAD. BFD MAD uses the BFD protocol for detecting multi-active collisions, and can work with or without intermediate devices. When you configure BFD MAD, follow these guidelines: Category BFD MAD VLAN Restrictions and guidelines • Do not enable BFD MAD on VLAN-interface 1. • If you are using an intermediate device, assign the ports of BFD MAD links to the BFD MAD VLAN on the device.
Default LACP MAD is disabled. Views Layer 2 aggregate interface view Predefined user roles network-admin mdc-admin Usage guidelines LACP MAD handles collisions in a different way than BFD MAD. To avoid conflicts, do not use LACP MAD together with BFD MAD. LACP MAD uses extended LACP packets for detecting multi-active collisions and requires an intermediate HP device that also supports LACP MAD packets.
undo mad exclude interface interface-type interface-number Default All physical network ports but the IRF physical ports and console port shut down when the IRF fabric transits to the Recovery state. Views System view Predefined user roles network-admin mdc-admin Parameters interface-type interface-number: Specifies a port by its type and number. Usage guidelines MAD action is not configurable for IRF physical ports.
Views VLAN interface view Predefined user roles network-admin mdc-admin Parameters ip-address: Specifies an IP address in dotted decimal notation. This IP address is bound to an IRF member for BFD detection and is called a "MAD IP address." mask: Specifies a subnet mask in dotted decimal notation. mask-length: Specifies a subnet mask in length, in the range of 0 to 32. member member-id: Specifies an IRF member ID.
Views System view Predefined user roles network-admin mdc-admin Usage guidelines When MAD detects that an IRF fabric has split into multiple IRF fabrics, it sets one of the IRF fabrics to the Detect state and all other IRF fabrics to the Recovery state. • The Detect-state IRF fabric is active and can continue to forward traffic. • The Recovery-state IRF fabrics are inactive. MAD shuts down all their physical ports except the IRF ports and the ports manually configured to not shut down.
• enhanced: Sets the binding mode to enhanced. • normal: Sets the binding mode to normal. Usage guidelines In IRF mode, use the shutdown command to shut down a physical port before you bind it to or remove it from an IRF port. To bring up the physical port after a binding or binding removal operation, use the undo shutdown command. In standalone mode, the shutdown and undo shutdown operations are not required.
