Enabling IRF auto-merge

When two IRF fabrics merge, you must reboot the member devices in the IRF fabric that fails in the master
election. The auto-merge feature enables the IRF fabric to automatically reboot all its member devices to
complete the merge.
This feature works only when it is enabled on both IRF fabrics that are merging.
This feature does not take effect on the IRF fabric merge that is caused by binding a physical interface to
an IRF port in IRF mode. You must manually reboot the devices that failed the master election to complete
the merge.
To enable IRF auto-merge:
Step
1.
Enter system view.
2.
Enable IRF auto-merge.

Configuring a member device description

Step
1.
Enter system view.
2.
Configure a description for a
member device.

Isolating an unused IRF member ID

IRF split or traffic storm occurs if an IRF member device tags an inter-chassis packet with a valid unused
member ID. This situation typically occurs when a poor-quality fiber module, fiber, or cable is used for IRF
connectivity.
To avoid an IRF split or traffic storm, isolate unused IDs in the valid IRF member ID range. The member
devices will drop packets that are tagged with an isolated member ID.
IMPORTANT:
Before you assign an isolated ID to a new member device, remove the isolation setting for the member ID.
To isolate an unused IRF member ID:
Step
1.
Enter system view.
2.
Isolate an unused IRF
member ID.
