Parameters
interval: Sets the IRF link down report delay in the range of 0 to 10000 milliseconds. If the interval is
set to 0, link down events are reported without any delay. The greater the interval, the slower the
service recovery.
Usage guidelines
This command is supported only in IRF mode. When you change the operating mode from IRF to
standalone, the command configuration is lost, regardless of whether you have saved the
configuration.
If the CFD or BFD feature is used in the IRF fabric, make sure the delay interval is shorter than the
maximum CCM lifetime and BFD session lifetime. For more information about CFD and BFD, see
High Availability Configuration Guide.
As a best practice, set the delay to 0 seconds in the following situations:
•
The IRF fabric requires a quick master/subordinate or IRF link switchover.
•
The BFD, BFD MAD, GR, or RRPP feature is used.
Examples
# Set the IRF link down report delay to 300 milliseconds.

irf mac-address persistent

Use undo irf mac-address persistent to enable the IRF fabric to change its bridge MAC address as
soon as the address owner leaves.
Syntax
