Hierarchy Level

Original CLI

ELS CLI for Platforms that Support FCoE


The beacon-period configuration statement is in a different hierarchy on the original CLI than on the Enhanced Layer 2 Software (ELS) CLI.


Set the interval between periodic beacons. Beacons perform virtual link maintenance for VN_Ports in a way that is similar to FIP keepalive advertisements.

The ENode sends periodic beacons every 90 seconds on behalf of the VN_Port. Each received beacon resets the session timer for the virtual link connection to the other VN_Port. If the FCF does not receive a beacon before the beacon timer expires, the VN_Port is considered as “down” and the virtual link is terminated. The beacon timer expires in 2.5 times the configured beacon timer value.
