Syntax irf auto-merge enable undo irf auto-merge enable Default This function is disabled. To complete an IRF merge, you must manually reboot the IRF fabric that has failed in the master election. Views System view Predefined user roles network-admin Usage guidelines To avoid an auto merge failure, make sure the auto merge function is enabled on both IRF fabrics that are merging. -
Page 14: Irf Domain
Usage guidelines This command is available in IRF mode. When you change the operating mode from IRF to standalone, the command configuration is lost, regardless of whether you have saved the configuration. To join an IRF fabric, a device must use the same software images as the master in the IRF fabric. When you add a device to the IRF fabric, software auto-update compares the startup software images of the device with the current software images of the IRF master. -

Predefined user roles network-admin Parameters domain-id: Specifies a domain ID for the IRF fabric. The value range is 0 to 4294967295. Usage guidelines This command is available in IRF mode. When you change the operating mode from IRF to standalone, the IRF domain setting is lost, regardless of whether you have saved the configuration. -
Page 16: Irf Mac-Address Persistent
When the IRF link changes from down to up, the link layer immediately reports the event to the IRF • fabric. HP recommends setting the delay to 0 seconds in one of the following situations: The IRF fabric requires a quick master/subordinate or IRF link switchover. •... -
Page 17: Irf Member
By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC address. Layer 2 protocols, such as LACP, use this bridge MAC address to identify the IRF fabric. On a switched LAN, the bridge MAC address must be unique. To avoid duplicate bridge MAC addresses, an IRF fabric can change its bridge MAC address automatically after its master leaves. -

new-member-id: Assigns a new ID to the IRF member device. The value range for this argument is 1 to 4. However, the assigned IRF member ID must be 1 or 2. If you use 3 or 4, the 7900 IRF fabric cannot be set up. -
Page 21: Irf-Port Global Load-Sharing Mode
Parameters priority: Specifies an IRF member priority value in the range of 1 to 32. 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. -
Page 22: Irf-Port Load-Sharing Mode
Usage guidelines The global IRF link load sharing mode applies to all IRF ports in the IRF fabric. You can configure the 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. -
Page 23: Irf-Port Member-Id/Port-Number
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. -

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 Restrictions and guidelines •... -
Page 27: Mad Exclude Interface
LACP MAD uses extended LACP packets for detecting multi-active collisions and requires an intermediate HP device that also supports LACP MAD packets. You must set up a dynamic link aggregation group that spans all IRF member devices between the IRF fabric and the intermediate device. -
Page 28: Mad Ip Address
If a port must be kept in up state for special purposes such as Telnet connection, exclude the port from the shutdown action. To avoid incorrect traffic forwarding, HP recommends not excluding any ports except the ports used for Telnet and MAD. -
Page 29: Mad Restore
member member-id: Specifies an IRF member ID. Usage guidelines To use BFD MAD, configure a MAD IP address on a BFD MAD-enabled VLAN interface for each IRF member. Make sure all the MAD IP addresses are on the same subnet. To avoid problems, only use the mad ip address command to configure IP addresses on the BFD MAD-enabled VLAN interface. -
