Huawei switches are designed to recognize and authenticate Huawei-certified optical modules. When a certified module is installed, the switch can read detailed information such as vendor name, part number, serial number, temperature, voltage, bias current, and optical power, enabling real-time monitoring and diagnostics . Non-Huawei-certified modules may not be fully recognized, and the switch may fail to read module information accurately, potentially causing data bus errors or interface issues .
Starting from V200R001 and later versions, Huawei switches generate non-certified optical transceiver alarms for all optical transceivers except encrypted Huawei-certified modules . These alarms indicate that the module is not officially certified but do not necessarily affect the operation of the module. Users can disable these alarms using the transceiver phony-alarm-disable command if needed .
To verify whether a module is detected and functioning properly, Huawei provides several commands:
display transceiver [interface interface-type interface-number | slot slot-id] – shows detailed module information including diagnostics .display interface <interface-type> <interface-number> – provides interface status, link state, and traffic statistics .display interface brief – lists all interfaces and their types for quick reference . These commands allow network administrators to monitor module health, including receive/transmit power, temperature, and bias current, ensuring reliable operation.Using non-certified optical modules can lead to:
Huawei switches can detect both certified and non-certified optical modules, but certified modules are fully supported and monitored, while non-certified modules may trigger alarms and have limited functionality. For reliable performance and accurate monitoring, it is recommended to use Huawei-certified optical modules and utilize the provided commands to check module status and diagnostics .
