For information about FEC, see the Installation Guide for your adapter (see References).
You can configure FEC settings with ethtool:
- To identify FEC
settings:
# ethtool --show-fec <interface> - To change FEC
settings:
# ethtool --set-fec <interface> [encoding auto|off|rs|baser]
The auto setting means the adapter firmware attempts to use the
FEC type required by the DAC or optical cable.
