Irf Member - HP 12500 series Command Reference Manual

Parameters
always: Enables the IRF bridge MAC address to be permanent regardless of master re-election or
leaving of the master.
timer: Enables the IRF bridge MAC address to remain the same for 6 minutes after the master
device leaves. If the device rejoins the IRF fabric before the time limit is reached, the IRF bridge
MAC address does not change. If not, the IRF fabric uses the bridge MAC address of the new
master as the IRF bridge MAC address.
Usage guidelines
Bridge MAC persistence is available in IRF mode. Changing the operating mode from IRF to
standalone can cause loss of the bridge MAC persistence setting, even if you have saved the
configuration.
An IRF fabric by default uses the bridge MAC address of the master device as its bridge MAC
address. This bridge MAC address is used by Layer 2 protocols, for example, LACP, to identify the
IRF fabric, and must be unique on a switched LAN for proper communication.
To avoid duplicate bridge MAC addresses, an IRF fabric can automatically change its bridge MAC
address after its master leaves, but the change causes temporary service interruption. Depending
on your network condition, you can enable the IRF fabric to preserve or change its bridge MAC
address after the master leaves.
If ARP MAD is used, execute the undo irf mac-address persistent command to enable immediate
bridge MAC address change after a master leaves.
If VRRP load balancing is used, execute the irf mac-address persistent always command to prevent
the IRF bridge MAC address from changing. For more information about VRRP, see High Availability
Configuration Guide.
If two IRF fabrics have the same bridge MAC address, they cannot merge.
