Monitoring Link Quality Using Forward Error Correction (FEC) Data on Arista Switches
Introduction When forward error correction is enabled, it provides a set of statistics which can be used to monitor the health of the link at layer 1. By comparing trends over time it may be possible to predict which links may experience service impacting error rates allowing action to be taken before these events. This document will describe these statistics and how to monitor them on an Arista switch running EOS. Forward Error Correction Forward error correction (FEC) is a technique used in data communications where data is portioned into blocks and to these blocks parity bits are added. When...
