FEC support for 100-gigabit port speeds

You can configure forward error correction (FEC) clause CL91 on switches. FEC CL91 can be configured on 100-gigabit interfaces. FEC CL91 clause is applied by default on these interfaces. If you do not want to apply the FEC CL91 clause, you can disable it.

• To disable the FEC mode: [edit] set interfaces interface-name gigether-options fec none
• To reenable the FEC mode: [edit] set interfaces interface-name gigether-options fec (fec74|fec91) or [edit] delete interfaces interface-name gigether-options fec none
• To check FEC status:
  show interfaces interface-name The output for the show command will list FEC statistics for a particular interface-name, including the FEC corrected errors count, the FEC uncorrected errors count, and the type of FEC that was disabled or enabled.
