Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Forward error correction

Forward error correction (FEC) enhances data reliability.

FEC modes supported in OS10:

  • CL74-FC — Supports 25G and 50G
  • CL91-RS — Supports 100G
  • CL108-RS — Supports 25G and 50G
  • off — Disables FEC
NOTE OS10 does not support FEC on 10G and 40G.

By default, FEC is enabled in SmartFabric Services mode.

Configure FEC
OS10(config)# interface ethernet 1/1/41
OS10(conf-if-eth1/1/41)# fec CL91-RS
