View interface information with FEC type
The show interfaces output for 25G/50G/100G interfaces shows the FEC types and codes for better understanding, if FEC is
enabled in that particular interface.
When FEC is configured as default (fec default), the operational FEC type is either CL91 or CL74 depending on the port
speed. But, the show output displays as Forward Error Correction(FEC) configured is default.
When FEC is enabled, the show output (fec enable) displays the FEC types as CL91 or CL74 depending on the port speed.
The following example shows the configuration and status information for one interface.
