Usage guidelines
If the undo form of this command is used, bridge MAC address of the current master replaces the
original IRF bridge MAC as soon as the original address owner leaves.
This command does not take effect if the IRF bridge MAC address is configured by using the
irf
mac-address
mac-address command.
If ARP MAD or ND MAD is used with the spanning tree feature, disable IRF bridge MAC persistence
by using the
undo irf mac-address persistent command. In addition, do not specify an IRF
bridge MAC address by using the
irf mac-address mac-address command.
If the IRF fabric uses a daisy-chain topology and has aggregate links with upstream or downstream
devices, do not execute the
undo irf mac-address persistent command. Use of this
command might result in transmission delay or packet loss after the address owner leaves or
reboots.
If the IRF fabric has multichassis aggregate links, do not use the
undo irf mac-address
persistent
command. Use of this command might cause traffic disruption.
By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC
address.
On a switched LAN, the IRF bridge MAC address must be unique for correct traffic transmission.
When IRF fabrics merge, IRF ignores the IRF bridge MAC address and 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.
Examples
# Enable the IRF bridge MAC address to persist forever.
<Sysname> system-view
[Sysname] irf mac-address persistent always
irf member description
Use irf member description to configure a description for an IRF member device.
Use
undo irf member description to restore the default.
