• Congure FEFD Aggressive mode globally using the fefd-global mode aggressive command in CONFIGURATION mode.
OS10(Config)# fefd-global mode aggressive
2 (Optional) Congure 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 specic 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 congure FEFD on an interface:
1 Do one of the following:
• Congure FEFD Normal mode on an interface using the fefd command in INTERFACE mode.
OS10(Conf-if-eth1/1/1)# fefd
• Congure FEFD Normal mode on an interface using the fefd mode normal command in INTERFACE mode.
OS10(Conf-if-eth1/1/1)# fefd mode normal
• Congure 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) Congure 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.
