FEC Configuration
FEC configurations are available on 100–Gigbit, 50–Gigabit and 25–Gigabit Ethernet interfaces.
To configure FEC, use the following commands.
● Enable FEC.
INTERFACE mode
fec enable {cl91|cl74|cl108}
The CL91 keyword enables RS-FEC on 100G interfaces as per IEEE. The system displays an error message when this is
applied on 25G or 50G interfaces.
The CL74 keyword enables BaseR-FEC on 25G or 50G interfaces as per 25G/50G Ethernet Consortium. The system
displays an error message when this is applied on 100G interfaces.
The CL108 keyword enables RS-FEC for single 25G lane as per IEEE 802.3by. The system displays an error message when
this is applied on 100G interfaces.
To disable FEC, use the no fec enable command.
● Set to default FEC value.
INTERFACE mode
fec default
390
