The optical switch cannot be started
If possible, remove and reinstall the optical modules to check whether the fault is rectified. This document describes how to troubleshoot fiber optic interfaces by addressing some of the fiber optic module and cabling specifications. Am I missing something or the optical monitoring only works when the link is up? I am trying to troubleshoot some fiber connections which were unreliable / not coming up and when I use the `show optical-monitor x/y/z` command, I get nothing. Those messages tell you what the switch detected (authentication mismatch, bad EEPROM, unsupported part number, PHY disagreement) and point to a small set of concrete checks.

The switch s optical port has a CRC check
To resolve CRC alignment errors, physical checks of the ports and layer 1 troubleshooting should be performed to identify and address the underlying issues. Please follow the below steps to resolve/isolate the issue : Ensure that the cable, smart jack, patch panel, and. This document describes what a CRC is, how it is used in the Frame Check Sequence (FCS) field of Ethernet frames, how CRC errors manifest on Nexus switches, and how CRC errors interact in Store-and-Forward switching. This article also describes Cut-Through switching scenarios, the most likely root. CRC errors can occur due to various reasons, including electrical interference, faulty hardware, or transmission issues. For example, the connected twisted pair or optical fiber is faulty, or the optical module on the interface does not work properly. As well, higher-layer OAM options such as EFM and BFD may not detect errors and trigger appropriate alarms.
