• Save the IRF configuration file on all MPUs of the IRF fabric. Assume the name of the configuration
file is a.cfg.
Configuration procedures
• Scenario I: Member switch 1 has one MPU, and it is corrupted. Member switch 2 has two MPUs.
1. Modify the member ID of the standby MPU on member switch 2 to make it consistent with that of
member switch 1.
2. Unplug the corrupted MPU on member switch 1, and insert the standby MPU of member switch 2
into member switch 1.
3. Configure IRF ports on member switch 1, and connect member switch 1 to member switch 2
through physical IRF ports.
The fast recovery is completed.
• Scenario II: Both member switches have only one MPU, and the MPU on member switch 1 is
corrupted.
1. Insert another MPU into member switch 2 and use it as the standby MPU of member switch 2.
2. Copy the configuration file a.cfg on the active MPU of member switch 2 to the standby MPU, and
set the file as the startup configuration file.
3. Modify the member ID of the standby MPU on member switch 2 to make it consistent with that of
member switch 1.
4. Unplug the corrupted MPU on member switch 1, and insert the standby MPU of member switch 2
into member switch 1.
5. Configure IRF ports on member switch 1, and connect member switch 1 to member switch 2
through physical IRF ports.
The fast recovery is completed.
Follow the step below to change the member ID of the standby MPU:
To do… Use the command… Remarks
Enter system view system-view —
Change the member ID of the
standby MPU
In IRF mode:

slot-number member-id member-id
In standalone mode:
set irf slot slot-number member-id
member-id
This command is only
applicable to the fast
recovery of the IRF. Using
this command in other cases
may cause unknown errors.
