show interface fec

Use this command to display the forward error correction (FECClosed FEC is a technique that detects and corrects errors during data transmission to maintain the reliability of the communication system.) statistics for an interface.

Displays only FEC statistics for physical interfaces, not management or logical interfaces.

Command Syntax

Copy
show interface (IFNAME|) fec

Parameters

IFNAME

Specifies the physical interface name.

Default

None

Command Mode

Execution mode and Privileged execution mode

Applicability

Introduced before OcNOS version 1.3. Introduced new fields, bit error, and symbol error; renamed the fields from Corrected Block Count and Uncorrected Block Count to Corrected Codeword Count and Uncorrected Codeword Count in the show output display in OcNOS version 6.6.0.

Example
