Debugging FEFD
To debug FEFD, use the first command. To provide output for each packet transmission over the FEFD enabled
connection, use the second command.
• Display output whenever events occur that initiate or disrupt an FEFD enabled connection.

An RPM Failover
In the event that an RPM failover occurs, FEFD becomes operationally down on all enabled ports for approximately 8-10
seconds before automatically becoming operational again.
