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
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 RRPP, 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.

Parameters
mac-address : Specifies a MAC address in the format of H-H-H. The MAC address cannot be the
all-zero or all-F MAC address, or a multicast MAC address. You can omit the consecutive zeros at
the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.
Usage guidelines
CAUTION:
IRF bridge MAC address change causes transient traffic disruption.
