Home / How to check the configuration of an optical module
Execute the following command to view detailed interface and optical module status: ethtool <devname> The output includes interface rate, module rate, link status (Link detected: yes is required for normal module operation), and interface configuration details. This document describes the principles and configurations of the Device Management features, and provides configuration examples of these features. When optical modules operate on a switch, it is usually necessary to read the module's internal information to understand its working status—such as connection status and real-time metrics like optical power and temperature. This guide gives a practical, CLI-focused workflow for checking SFP health and diagnostics on Cisco switches, shows the exact commands you'll use, explains what the numbers mean, and compares OEM (Cisco) vs third-party modules so you can pick the right SFP module supplier for reliability and cost. 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.
Additionally, identifying module information helps detect coding compatibility between the module and the switch. The following introduces the specific operations to view the working status
