R3303-HP HSR6800 Routers IRF Command Reference

Usage guidelines
IRF bridge MAC persistence specifies the amount of time an IRF fabric can continue using the old master
bridge MAC address as its bridge MAC address after a master re-election.
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.
Layer 2 protocols, such as LACP, use this bridge MAC address to identify the IRF fabric. On a switched
LAN, the bridge MAC address must be unique.
To avoid duplicate bridge MAC addresses, an IRF fabric can automatically change its bridge MAC
address after its master leaves. However, the change causes temporary service disruption. Depending on
the 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, use the undo irf mac-address persistent command to enable immediate bridge
MAC address change after a master leaves.
If two IRF fabrics have the same bridge MAC address, they cannot merge.
Examples
# Enable the IRF bridge MAC address to be permanent.
<Sysname> system-view
[Sysname] irf mac-address persistent always
irf member
Use irf member to assign a member ID to the device in standalone mode.
Use undo irf member to restore the default.
Syntax
irf member member-id
undo irf member
Default
The device operates in standalone mode and has no member ID.
Views

Default command level
3: Manage level
Parameters
member-id: Assigns an IRF member ID to the device. The value range is 1 to 2.
Usage guidelines
You must assign an IRF member ID to a device before enabling its IRF mode. This member ID must be
unique among all IRF member devices.
The new member ID takes effect at reboot.
