fec
Configures Forward Error Correction
(FEC) on either a 100 GbE port or a
channelized 100 GbE port operating at 25 Gbps speed.
Syntax
-
default fec port {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}
-
fec
{auto|cl91|cl108|cl74}
-
no fec port {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}
Command Parameters
- {auto|cl91|cl108|cl74}
- Configures FEC on either a 100 GbE port or a
channelized 100 GbE port operating at 25 Gbps speed. On the 100 GbE ports, only
the Clause 91 and Clause 108 options are supported. On channelized ports, you can
configure either Clause 108 for extra latency or Clause 74 for reduced latency.
You can also configure the auto option to automatically configure FEC based on port speed and
pluggable module type.
- FEC is not supported on 100 Gbps
ports that operate at 40 Gbps speed or on a management port. On ports that support
FEC configuration, ensure that you
configure the same option at both end points. Otherwise, the link does not come
up.
Default
The default is disabled.
