The G.709 wrapper must be enabled to enable forward error correction (FEC) mode on the controller.
Standard FEC is the default mode; therefore, if you use the no g709 fec command, standard FEC is used.
To display the FEC mode, use the show controller dwdm command.

Examples
This example shows how to configure the FEC mode on a DWDM controller:
RP/0/RSP0/CPU0:router(config)# controller dwdm 0/6/0/0
RP/0/RSP0/CPU0:router(config-dwdm)# admin-state out-of-service
RP/0/RSP0/CPU0:router(config-dwdm)# commit
RP/0/RSP0/CPU0:router(config-dwdm)# g709 fec standard
RP/0/RSP0/CPU0:router(config-dwdm)# commit
RP/0/RSP0/CPU0:router(config-dwdm)# admin-state in-service
RP/0/RSP0/CPU0:router(config-dwdm)# commit
