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. 

Syntax

Parameters 

member-id

: Specifies the ID of an IRF member. 

text

: Specifies a description, a string of 1 to 127 characters.  

Examples 

# Configure the description as
