Port: Optical Ports on the AC Cannot Go Up
Use an optical fiber to perform a loopback test on the Huawei device. If the link goes Up, the Huawei device is working properly, and
Viewing Huawei Switch Optical Ports
Use the display transceiver command to view detailed optical port information, including type, link status, and transmit/receive power.
Viewing Optical Module Information
To check the optical module on a Huawei switch, you can use the following commands:
- All ports:
display transceiver– shows basic information for all optical ports, including transceiver type, connector type, wavelength, transfer distance, and vendor details . - Specific port:
display transceiver interface– displays information for a single optical port . - Verbose output: Add the
verboseparameter to view detailed diagnostic data such as temperature, voltage, bias current, and transmit/receive power . Example:CodeCopy
display interface 10ge 1/0/1 transceiver verbose
Checking Port Link Status and Traffic
- Use
display interfaceto see port rate, link status (UP/DOWN), and traffic statistics . display interface briefprovides a summary of all ports, including link status and basic traffic counters .
Diagnostic Commands
display transceiver diagnosis interface– retrieves Digital Diagnostic Monitoring (DDM) information for troubleshooting optical modules, including transmit and receive power levels, which helps identify faulty modules or low signal issues .
Certified vs Non-Certified Modules
Huawei recommends using Huawei-certified optical modules. Non-certified modules may cause installation issues, abnormal data bus behavior, or even damage the switch interface due to nonstandard sizes or electrical defects . Always verify module compatibility before installation.
Summary
By combining these commands, you can:
- Monitor real-time optical port performance
- Verify transceiver specifications and health
- Troubleshoot link or signal issues
- Ensure proper operation with certified modules
These tools are essential for maintaining reliable optical connectivity and diagnosing potential faults in Huawei switch networks .
