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.
When you configure the IRF link down report delay, follow these restrictions and guidelines:
•
Make sure the IRF link down report delay is shorter than the heartbeat or hello timeout settings
of upper-layer protocols (for example, CFD and OSPF). If the report delay is longer than the
timeout setting of a protocol, unnecessary recalculations might occur.
•
Set the delay to 0 seconds in the following situations:
The IRF fabric requires a fast master/subordinate or IRF link switchover.

The BFD or GR feature is used.

You want to shut down an IRF physical interface or reboot an IRF member device. (After you

complete the operation, reconfigure the delay depending on the network condition.)
Examples
# Set the IRF link down report delay to 300 milliseconds.
