R21xx-HP FlexFabric 11900 IRF Configuration Guide

Depending on your network condition, enable the IRF fabric to preserve or change its bridge MAC

address after the master leaves. Available options include:

• irf mac-address persistent timer—Bridge MAC address of the IRF fabric is retained for 6 minutes

after the master leaves. If the master does not return before the timer expires, the IRF fabric uses the

bridge MAC address of the new master as its bridge MAC address. This option avoids unnecessary

bridge MAC address change due to a device reboot, transient link failure, or purposeful link

disconnection.

• irf mac-address persistent always—Bridge MAC address of the IRF fabric does not change after

the master leaves.

• undo irf mac-address persistent—Bridge MAC address of the new master replaces the original one

as soon as the old master leaves.

IMPORTANT:

If VRRP load balancing is used, configure the irf mac-address persistent always command to prevent the

IRF bridge MAC address from changing.

If two IRF fabrics have the same bridge MAC address, they cannot merge.

To configure the IRF bridge MAC persistence setting:

By default, the IRF fabric's

bridge MAC address is retained

permanently even after the

master leaves.

Enabling software auto-update for system software image

synchronization

IMPORTANT:

To ensure a successful software auto-update in a multi-user environment, prevent the action of rebootin

or swapping MPUs during the software auto-update process. You can configure the information center to

output the software auto-update status to configuration terminals (see
