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

Make sure the IRF link down report delay is shorter than the heartbeat or hello timeout settings of upper layer protocols (for example, CFD, VRRP, FCoE, 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.
