Assigning a member ID to each IRF member switch

CAUTION:
In an IRF fabric, changing IRF member IDs might cause undesirable configuration changes and even data
loss. Before you do that, back up the configuration and make sure you fully understand the impact on your
network. For example, all member switches in an IRF fabric are the same model. If you swapped the IDs
of any two members, their interface settings would also be swapped.
By default, the member IDs of all switches are 1. To create an IRF fabric, you must assign a unique IRF
member ID to each switch.
Perform this task before the IRF fabric is formed. To prevent any undesirable configuration change or data
loss, avoid changing member IDs after the IRF fabric is formed.
The new member ID takes effect at a reboot. After the switch reboots, the settings on all member-ID
related physical resources (including common physical network ports) are removed and require
reconfiguration, regardless of whether you have saved the configuration.
To set a member ID for a switch:
Step
1. Enter system view.
2. Assign an IRF member ID to
the switch.
3. Save the configuration.
4. Reboot the switch.

Specifying a priority for each member switch

IRF member priority represents the possibility for a device to be elected the master in an IRF fabric. The
higher the priority, the higher the possibility.
A member priority change affects the election result at the next master election, but does not cause
immediate master re-election.

Remarks
N/A
The default IRF member ID is 1.
Optional.
If you have bound physical ports
to IRF ports or assigned member
priority, save the configuration
before rebooting the switch so
these settings can continue to
take effect after the reboot.
