Usage guidelines
By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC address.
Layer 2 protocols, such as LACP, use this bridge MAC address to identify the IRF fabric. On a switched
LAN, the bridge MAC address must be unique.
To avoid duplicate bridge MAC addresses, an IRF fabric can change its bridge MAC address
automatically after its master leaves. However, the change causes temporary service disruption. To avoid
this situation, configure bridge MAC persistence.
If two IRF fabrics have the same bridge MAC address, they cannot be merged into one IRF fabric.
If ARP MAD is used, you must use the
undo irf mac-address persistent
command disable IRF bridge MAC
persistence.
Examples
# Enable the IRF bridge MAC address to persist forever.
<Sysname> system-view
[Sysname] irf mac-address persistent always
