Checking the optical ports on a Huawei 5024e switch
Use Huawei CLI commands like display transceiver and display interface to check optical port status, module details, and diagnostic information.
Viewing Optical Module Information
To check the optical transceivers on your Huawei 5024e switch:
- View all optical ports: Run the command:
display transceiverThis shows the type, connector, wavelength, transfer distance, vendor, and basic operational status of all optical modules on the switch . - View a specific port: Use:
display transceiver interface <interface-type> <interface-number>Replace<interface-type>and<interface-number>with the port identifier (e.g.,GE1/0/1) to see detailed information for that port . - Detailed diagnostics (DDM): For receive and transmit power, temperature, voltage, and bias current, add the
verboseparameter:display transceiver interface <interface-type> <interface-number> verboseThis provides real-time monitoring data for troubleshooting and performance analysis .
Checking Port Link Status
To verify if the optical port is operational:
- Check interface status:
display interface <interface-type> <interface-number>This shows the link status (UPindicates normal operation), port rate, transceiver type, and traffic statistics . - View all interfaces briefly:
display interface briefThis command lists all ports, their operational status, speed, and duplex settings, helping identify inactive or down ports .
Troubleshooting Tips
- Physically down ports may be caused by hardware issues (faulty SFPs, fibers, or cables) or software misconfigurations (mismatched negotiation mode, rate, or duplex) and environmental factors .
- Check transceiver power levels using the verbose output to ensure the optical signal is within acceptable thresholds.
- Verify connections and replace faulty SFP modules or cables if necessary.
- Monitor traffic statistics to detect errors, drops, or alignment issues that may indicate port or fiber problems . By combining these commands, you can effectively monitor, diagnose, and maintain the optical ports on your Huawei 5024e switch.
