API Guide
● Configure FEFD Aggressive mode globally using the fefd-global mode aggressive command in CONFIGURATION
mode.
OS10(Config)# fefd-global mode aggressive
2. (Optional) Configure the FEFD interval using the fefd-global interval command in CONFIGURATION mode and
enter the interval in seconds. The range is from 3 to 255 seconds.
OS10(Config)# fefd-global interval 20
3. (Optional) Disable FEFD on a specific interface if required using the fefd disable command in INTERFACE mode.
OS10(Conf-if-eth1/1/1)# no fefd interval 20
Enable FEFD on interface
To configure FEFD on an interface:
1. Do one of the following:
● Configure FEFD Normal mode on an interface using the fefd command in INTERFACE mode.
OS10(Conf-if-eth1/1/1)# fefd
● Configure FEFD Normal mode on an interface using the fefd mode normal command in INTERFACE mode.
OS10(Conf-if-eth1/1/1)# fefd mode normal
● Configure FEFD Aggressive mode on an interface using the fefd mode aggressive command in INTERFACE mode.
OS10(Conf-if-eth1/1/1)# fefd mode aggressive
2. (Optional) Configure the FEFD interval using the fefd interval command in INTERFACE mode and enter the interval in
seconds. The range is from 3 to 255 seconds.
OS10(Conf-if-eth1/1/1)# fefd interval 20
Reset FEFD err-disabled interface
When the system detects a far-end failure in FEFD aggressive mode, the interface moves to err-disabled state. To bring back
the interface to FEFD operational state:
● Enter the fefd reset command in EXEC mode.
OS10# fefd reset ethernet 1/1/1
Display FEFD information
To view FEFD information:
● To view FEFD information globally, use the show fefd command in EXEC mode.
● To view FEFD information for an interface, use the show fefd interface command in EXEC mode.
The following is a sample output of FEFD global information:
OS10# show fefd
FEFD is globally 'ON', interval is 15 seconds, mode is Normal.
