You can change several port properties, including description, port speed, MTU, Forward Error Correction (FEC), port breakout, header stripping, Link Fault Signaling (LFS), admin state.
Note
(SLX only) If the port you are configuring is part of a port channel, do not change the MTU or the Port Speed values from the ExtremeCloud Orchestrator interface.Note
Port speed change is not supported for 400G ports.Breakout is not supported for 400G ports.
Note
(SLX prior to 18s.0.1g) Ports with auto speed configured and not connected, cannot have speed reconciled. Without the speed reconciliation, ports are not listed in the port-channel and are not allowed to breakout or un-breakout.Note
FEC can be updated only when the port is in shutdown state.
