5) When the IRF links fail, the system outputs error messages for detecting an IRF link and card
failure.
#May 7 09:13:42:388 2010 H3C STM/4/LINK STATUS CHANGE:
Trap 1.3.6.1.4.1.2011.10.2.91.6.0.1: 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 H3C DEVM/1/BOARD STATE CHANGES TO FAILURE:
Because the member ID of Device B is 2, when the MAD mechanism detects errors, the state of Device
B changes to recovery and all ports on Device B except for the reserved ones are shut down.
# If the master fails, log in to the console port of Device B and use the mad restore command to recover
Device B to active state and bring up disabled ports on the device.

[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...

#May 7 09:23:16:050 2010 H3C IFNET/4/INTERFACE UPDOWN:
Trap 1.3.6.1.6.3.1.1.5.4: Interface 277872640 is Up, ifAdminStatus is 1,
ifOperStatus is 1
%May 7 09:23:16:069 2010 H3C IFNET/3/LINK_UPDOWN: GigabitEthernet2/3/0/2 link status is UP.
#May 7 09:23:16:302 2010 H3C LAGG/1/AggPortRecoverActive:
Trap 1.3.6.1.4.1.2011.5.25.25.2.4: Aggregation Group 1: port
member 277872640 becomes ACTIVE!
%May 7 09:23:16:322 2010 H3C LAGG/5/LAGG_ACTIVE: Member port GigabitEthernet2/3/0/1 of
aggregation group BAGG1 becomes ACTIVE.
%May 7 09:23:16:370 2010 H3C IFNET/3/LINK_UPDOWN: Bridge-Aggregation2 link status is UP.
%May 7 09:23:16:381 2010 H3C IFNET/3/LINK_UPDOWN: Vlan-interface1 link status is UP.
%May 7 09:23:16:391 2010 H3C IFNET/5/LINEPROTO_UPDOWN: Line protocol on the interface
Vlan-interface1 is UP.
The output information shows that Device B is restored, and then you can repair Device A and the IRF
links.
# When Device A and IRF links are recovered, reboot Device A. Device B prompts that the IRF port is
up and a new card is inserted.
