View switch optical port information

You can view optical port information on a switch using CLI commands that display interface status, module type, diagnostic data, and optical power metrics. Viewing Optical Module Status on Cisco SwitchesCheck Interface StatusUse the command: show interface to see link state, interface rate, module type, and traffic statistics. If you are unsure of the interface, run show interface status to list all interfaces and their types.

View Module Inventory

Execute show inventory to display all optical modules installed, including serial numbers, part numbers, and module types.

Detailed Module Information

For IDPRO

M data of a specific module, run: show idprom interface. This provides transceiver type, encoding, wavelength, and supported distances. Diagnostic Monitoring (DOM/DDM)Use show fiber-ports-optical-transceiver or show fiber-ports-optical-transceiver-info to view real-time metrics such as: Temperature (°C)Voltage (V)Current (mA)Transmit (TX) and receive (RX) optical power (mW)TX fault and loss-of-signal (LOS) indicators.

Viewing Optical Module Status on Extreme EXOS SwitchesUse the command: show ports media or show ports transceiver to display optical transceiver details for all ports. This includes DDMI-supported metrics like temperature, voltage, and optical power.

General Steps for Any Switch

Access the Switch CLIConnect via console, SSH, or Telnet. Enter privileged EXEC mode (e.g., enable on Cisco switches).

Identify the Port

Determine the interface ID where the optical module is installed.

Run Vendor-

Specific Commands

Cisco: show interface, show inventory, show idprom, show fiber-ports-optical-transceiver. Extreme: show ports transceiver or show ports media.

Interpret Output

Check link status (UP/DOWN), module type, wavelength, supported distance, and real-time diagnostics. Use this information for troubleshooting, verifying module compatibility, or monitoring optical performance. By following these steps, network engineers can effectively monitor and manage optical ports, ensuring proper operation and early detection of potential issues.
