fec mode

Configures the various Forward Error Corrections (FEC) parameters for the interface.

Syntax

fec mode { FC-FEC | RS-FEC | auto-negotiation | disable }

no fec mode

Command Default

By default, SLX-OS selects one of FC-FEC, RS-FEC or disable based on port type, configured speed, and the optic inserted in that port.

Parameters

FC-FEC: Set the FEC mode to FC-FEC in manual mode.
RS-FEC: Set the FEC mode to use RS-FEC in manual mode.
auto-negotiation: Set the FEC mode to auto-negotiation. This setting is only applicable for 25G DAC cables.
disable: Disable FEC on the interface.

Modes

Interface Ethernet mode

Usage Guidelines

The no format of this command resets the FEC configuration on the interface to the default configuration.

Examples

The following example configures the ethernet port 0/1 with RS-FEC.

SLX # config terminal
SLX (config)# interface Ethernet 0/1
SLX (conf-if-eth-0/1)# fec mode RS-FEC
