How to Check Optical Info On Cisco Nexus Switch. Most people check their optical fiber power info with an Optical Power Meter. So today we will learn how to check optical info on Cisco Switch through command without Optical Power Meter. It is very simple but still, people don't understand this and can't extract optical info. Follow the below command to check Optical Info on Cisco Nexus 3000 Series Switch. So let's get started.
Command:
switch# show interface transceiver details
By using this command, you can see all the transceiver modules installed on your switch, optical info, power level, wavelength, and other diagnostic information of all the ports.
