Enabling FEFD on an Interface
To enable, change, or disable FEFD on an interface, use the following commands.
● Enable FEFD on a per interface basis.
INTERFACE mode
fefd
● Change the FEFD mode.
INTERFACE mode
fefd [mode {aggressive | normal}]
● Disable FEFD protocol on one interface.
INTERFACE mode
fefd disable
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}
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.
EXEC Privilege mode
debug fefd events
● Provide output for each packet transmission over the FEFD enabled connection.
EXEC Privilege mode
debug fefd packets
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.
