Usage guidelines
The device delays reporting link status change events of an IRF port, but it does not delay reporting
link status change events of an IRF physical interface.
Examples
# Set the IRF link status change report delay to 300 milliseconds.
<Sysname> system-view
[Sysname] irf link-delay 300
irf mac-address persistent
Use
irf mac-address persistent
to configure IRF bridge MAC persistence.
Use
undo irf mac-address persistent
to disable IRF bridge MAC persistence.
Syntax
irf mac-address persistent
{
always
|
timer
}
undo irf mac-address persistent
Default
The IRF bridge MAC address remains unchanged for 6 minutes after the address owner leaves.
Views

Predefined user roles

Parameters
always
: Enables the IRF bridge MAC address to be permanent. The IRF bridge MAC address does
not change after the address owner leaves the fabric.
timer
: Enables the IRF bridge MAC address to remain unchanged for 6 minutes after the address
owner leaves. If the owner rejoins the IRF fabric within the time limit, the IRF bridge MAC address
does not change. If the owner does not rejoin the IRF fabric within the time limit, the IRF fabric uses
the bridge MAC address of the current master as the bridge MAC address.
Usage guidelines
CAUTION:
IRF bridge MAC address change will cause transient traffic disruption.
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.
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.
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.
