Read optical power link service for link health diagnostics

摘要

A method is provided for monitoring a state of an optical link in a Fiber Channel infrastructure and includes sending an Extended Link Service (ELS) request to read an optical power of the optical link, and diagnosing a degradation of the optical link, based on a response to the ELS request.

1. A method of monitoring a state of an optical link in a Fibre Channel infrastructure, the method comprising:
sending an Extended Link Service (ELS) request to read an optical power of the optical link; diagnosing a degradation of the optical link, based on a response to the ELS request; determining whether the optical power of the optical link is a cause of an occurring link error; if no link errors are occurring, determining whether the optical power of the optical link is outside of a threshold range including a low optical power level threshold and a high optical power level threshold; and renegotiating a lower link speed for the optical link, in response to the optical power of the optical link being outside of the threshold range.
