Accessing the Huawei switch s optical port

Optical network knowledge brief Published 18 Jul 2026

Prepared for preliminary research by the COETZER OPTICAL knowledge desk. Confirm compatibility, loss budgets and installation requirements against current standards and product documentation.

You can access and monitor Huawei switch optical ports using the display transceiver and display interface commands to view module details, port status, and diagnostic information.Viewing Optical Module Information

To check the optical module on a specific port, use the following commands:

  • Display all optical ports: display transceiver This shows information for all optical modules installed on the switch .
  • Display a specific optical port: display transceiver interface Replace and with the port type and ID. This provides details such as transceiver type, connector type, wavelength, transfer distance, vendor, and serial number .
  • Verbose mode for power and diagnostics: display transceiver interface verbose This command shows receive and transmit power, temperature, voltage, and bias current, which is useful for troubleshooting .
  • Digital Diagnostic Monitoring (DDM): display transceiver diagnosis interface Displays real-time diagnostic data for the optical module, helping identify faults or abnormal conditions .
Checking Port Status
  • Port link and traffic statistics: display interface Shows port rate, link status (UP indicates normal operation), transceiver type, and traffic statistics such as unicast, multicast, broadcast, errors, and collisions .
  • Summary of all ports: display interface brief Provides a quick overview of all ports, including optical interfaces, their status, and link information .
Best Practices and Troubleshooting
  • Use Huawei-certified optical modules to avoid compatibility issues, data bus errors, or physical damage to the interface .
  • Check module specifications against the port configuration using display interface GigabitEthernet x/x/x for GE ports to ensure rate and wavelength match .
  • Measure optical power with an optical power meter if needed, and consider using optical attenuators for long-distance modules .
  • Reinstall or replace faulty modules if the port does not come up, and reboot the switch if necessary .
  • Exercise caution on live networks, as removing modules or restarting the switch may affect services . By following these commands and best practices, you can effectively access, monitor, and troubleshoot Huawei switch optical ports.
