fec

Use this command to enable forward error correction (FEC) for an interface in adherence with IEEE requirements (IEEE 802.3bj -CL 91). This command is available only on interfaces operating at 100G, 50G and 25G speeds. If you change the speed of an interface to a speed at which FEC is not supported, FEC is automatically disabled on the interface. When the interface returns to the speed that supports FEC, LCOS SX retains the original FEC configuration and re-applies it on the interface.
