Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Configuring FEC using MSM

You can configure FEC on interfaces from MSM when the switch is in Fabric mode.

MSM sends the FEC value that is to be configured for the interface and this value is configured for the interface. This configuration is not retained across breakout modes. Configuration of FEC from MSM for IOM in full-switch mode is not supported.

The FEC configuration from MSM is supported for 25, 50, and 100G speeds and for uplink ports only in Smartfabric mode. The FEC configuration from MSM is not supported for spinner ports(breakout FEM, virtual ports) and the server ports.

FEC has two parameters configured and negotiated. The configured FEC is the user configured value and the negotiated value is the value that is negotiated based on optics and peer.

This feature is enabled only when the switch is in Fabric mode.
