API Guide

To disable FEFD on an interface when FEFD globally enabled, use the fefd disable command on the
interface.
To unconfigure FEFD on an interface, use either the no fefd command or the no fefd mode
command. To return to the default FEFD interval, use the no fefd interval command.
Example
OS10(conf-if-eth1/1/9)# fefd
OS10(conf-if-eth1/1/9)# fefd mode aggressive
OS10(conf-if-eth1/1/9)# fefd mode interval 10

Usage
Information
The fefd-global command without arguments enables Normal mode with the default FEFD interval of
15 sseconds.
If you use the no fefd-global command, the system does not disable FEFD if the fefd-global
mode command is already present in the configuration. Similarly, if you use the no fefd-global mode
command, the system does not disable FEFD if the fefd-global command is already present in the
configuration.
To unconfigure FEFD globally, use either the no fefd-global command or the no fefd-global
mode command. To return to the default FEFD interval, use the no fefd-global interval
command.
Example
OS10(config)# fefd-global
OS10(config)# fefd-global mode aggressive
OS10(config)# fefd mode interval 10
