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.

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.

Make sure the IRF link down report delay 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 fast 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.
