View port optical module information on Huijue switches

Article Overview

Use the display transceiver and display transceiver diagnosis commands to view detailed optical module information on Huawei switches.

Basic Commands

  1. View all optical modules on the switch:

    CodeCopydisplay transceiver This command lists all optical ports and their modules, showing type, vendor, wavelength, and transfer distance .

  2. View a specific optical module on an interface:

    CodeCopydisplay transceiver interface <interface-type> <interface-number> Replace <interface-type> and <interface-number> with the actual interface, e.g., GigabitEthernet 0/0/1 .

  3. View detailed diagnostic information (DDM):

    CodeCopydisplay transceiver interface <interface-type> <interface-number> verbose This provides real-time data such as temperature, voltage, bias current, transmit and receive power, and alarm thresholds .

  4. Run diagnostics on a module:

    CodeCopydisplay transceiver diagnosis interface <interface-type> <interface-number> This command checks the module's operational status and reports any faults or abnormal readings .

Additional Information

  • Interface status check: Use display interface <interface-type> <interface-number> or display interface brief to confirm the link is UP before interpreting module data .
  • Module details: Output typically includes transceiver type, connector type, wavelength, transfer distance, vendor name, serial number, and manufacturing date .
  • Certified modules: Huawei recommends using Huawei-certified optical modules to ensure accurate readings, proper installation, and device compatibility. Non-certified modules may cause data bus errors, interface damage, or incorrect diagnostic information .

Practical Tips

  • Always verify the interface is active before checking module data.
  • Use the verbose parameter for troubleshooting power or signal issues.
  • Regularly monitor DDM parameters to prevent failures due to temperature, voltage, or current anomalies.
  • Avoid non-Huawei-certified modules to maintain switch reliability and accurate monitoring. By following these commands and guidelines, you can effectively monitor, diagnose, and maintain optical modules on Huawei switches.
