Parameters
timer: Bridge MAC address preservation mode for an IRF virtual device. With this keyword specified,
the bridge MAC address is preserved for 6 minutes when the master leaves.
always: Bridge MAC address preservation mode. With this keyword specified, the bridge MAC
address is preserved permanently.
Description
Use the irf mac-address persistent command to configure the preservation time of the bridge MAC
address of an IRF virtual device.
Use the undo irf mac-address persistent command to configure the IRF virtual device not to
preserve the bridge MAC address when the master leaves.
By default, the bridge MAC address of an IRF virtual device is preserved for 6 minutes.
Preserve for six minutes: When the master leaves, the bridge MAC address does not change
within six minutes. If the master does not come back when the preservation time expires, the IRF
virtual device uses the bridge MAC address of the newly elected master as its bridge MAC
address.
