Use this feature to configure the bridge MAC address of an IRF fabric. Layer 2 protocols, such as LACP, use the IRF bridge MAC address to identify an IRF fabric. On a switched LAN, the bridge MAC address must be unique.
When IRF fabrics merge, IRF ignores the IRF bridge MAC address and only checks the bridge MAC address of each member device in the IRF fabrics. IRF merge fails if any two member devices have the same bridge MAC address.
After IRF fabrics merge, the merged IRF fabric uses the bridge MAC address of the merging IRF fabric that won the master election as the IRF bridge MAC address.
The following methods are available to configure the IRF bridge MAC address for an IRF fabric:
The IRF fabric always uses the specified MAC address as the IRF bridge MAC address.
This feature specifies the amount of time an IRF fabric can continue using a MAC address as the IRF bridge MAC address after the address owner leaves. By default, the bridge MAC address of the master device becomes the IRF bridge MAC address upon the setup of the IRF fabric.
