Run the display transceiver [ interfaceinterface-typeinterface-number | slotslot-id ] [ verbose ] command to view information about the optical module on a specified interface. Optical modules work in the switch usually need to read the internal information of the module to understand its working status, such as module connectivity and real-time collection of light, temperature, etc. By checking module health, compatibility, and digital diagnostics, you can quickly confirm correct installation, detect optical problems, and maintain accurate hardware. This article provides instructions on how to view the Optical Module Status on your switch through the Command Line Interface (CLI). The Cisco Small Business Series Switches allow you to plug in a Small Form-factor Pluggable (SFP) transceiver in their optical modules to connect fiber optic cables. It takes the device name (like swp1) as an argument. See man ethtool(8) for details. Many enterprise switches from vendors like Cisco and Juniper Networks provide built-in commands that allow engineers to read Digital Optical.
