Execute the following command to view detailed interface and optical module status: show interface <interface-type> <interface-number>Execute the following command to view detailed interface and optical module status: show interface <interface-type> <interface-number>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. Additionally, identifying module information helps detect coding. This article provides instructions on how to view the Optical Module Status on your switch through the Command Line Interface (CLI). In. Cisco switches support Digital Optical Monitoring (DOM), also called DDM, which provides real-time monitoring of: Understanding these metrics helps engineers detect degradation early, even if basic connectivity tests pass. The commands vary by Cisco platform. com, our Cisco-certified engineers help enterprises monitor, test, and manage optical transceivers.
