5. Recover the IRF fabric after LACP MAD detects an IRF split:

When the IRF links fail, the system outputs IRF link problem and card failure error messages.

Because it has a lower member ID than Device A, Device B transits to the Recovery state and shuts

down all its ports except those excluded from the shutdown action.

Trap 1.3.6.1.4.1.2011.10.2.91.6.0.1<StackPortLinkStatusChange>: Physical index of

the member is 2, member ID is 1. Link status of the IRF port with port index 1 and

member ID 1 turned to 2.

#May 7 09:13:42:720 2010 HP DEVM/1/BOARD STATE CHANGES TO FAILURE:

# If the master fails, log in to the console port of Device B and use the mad restore command to

recover Device B.

[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...
