Enter system view. system-view N/A2. Configure a description for amember device. irf member member-id description text By default, no member devicedescription is configured.Configuring IRF bridge MAC persistenceBy 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 switchedLAN, the bridge MAC address must be unique.To avoid duplicate bridge MAC addresses, an IRF fabric can change its bridge MAC addressautomatically after the bridge MAC owner leaves. However, the change causes temporary trafficdisruption.Depending on the network condition, enable the IRF fabric to preserve or change its bridge MACaddress after the address owner leaves. Available options include:• irf mac-address persistent timer—Bridge MAC address of the IRF fabric is retained for 6 minutesafter the address owner leaves. If the owner does not return before the timer expires, the IRF fabricuses the bridge MAC address of the current master as its bridge MAC address. This option avoidsunnecessary bridge MAC address changes caused by device reboot, transient link failure, orpurposeful link disconnection.• irf mac-address persistent always—Bridge MAC address of the IRF fabric does not change afterthe address owner leaves.NOTE:IRF fabrics cannot merge if they have the same bridge MAC address. If you use the removed bridgeMAC owner as the master device in a new fabric, the bridge MAC of the new fabric is the same as theold fabric. For the two IRF fabrics to merge, you must change the bridge MAC address of the old IRFfabric.• undo irf mac-address persistent—Bridge MAC address of the current master replaces the originalone as soon as the owner of the original bridge MAC address leaves.IMPORTANT:You must configure the irf mac-address persistent always command if VRRP load balancing is used.To configure the IRF bridge MAC persistence setting:
