Disabling an interface shuts down all protocols working on that interface's connected line. It does not delete your previous FEFD configuration which you can enable again at any time. To set up and activate two or more connected interfaces, use the following commands. 1. Setup two or more connected interfaces for Layer 2 or Layer 3. INTERFACE mode ip address ip address, switchport 2. Activate the necessary ports administratively. INTERFACE mode no shutdown 3. INTERFACE mode fefd {disable | interval | mode} Example of Viewing FEFD Configuration Dell(conf-if-te-1/0)#show config ! interface TengigabitEthernet 1/0 no ip address switchport fefd mode normal no shutdown Dell(conf-if-te-1/0)#do show fefd | grep 1/0 Te 1/0 Normal 3 Unknown 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.
