Setting Optical Power Alarm Thresholds

Setting Optical Power Alarm Thresholds


You can set optical power alarm so that the device generates alarms if the transmit or receive power of an optical module exceeds a threshold. An alarm may indicate that the optical module is faulty.

The default optical power alarm thresholds of an optical module are fixed and cannot be changed. These thresholds are determined through extensive testing and verification. You can configure alarm thresholds but they must be within the default range. However, this is not recommended. If an optical power alarm is generated, the first step of troubleshooting is to check the optical module and connected fibers.

  • You are advised to use Huawei-certified optical modules. If non-Huawei-certified optical modules are used, incorrect optical module information may be obtained during the query of optical power information.

  • Only enhanced optical modules support the query of optical power information.

  • The XGE interface connected to LE1D2FW00S01 card does not support the configuration of optical power alarm thresholds.


  1. (Optional) Run display transceiver [ interface interface-type interface-number | slot slot-id ] [ verbose ]

    Conventional, manufacturing, and alarm information about the optical module on a specified interface is displayed.

  2. Run system-view

    The system view is displayed.

  3. Run interface interface-type interface-number

    The interface view is displayed.

  4. Run set transceiver { transmit-power | receive-power } { upper-threshold | lower-threshold } threshold

    Upper and lower alarm thresholds are set for the transmit and receive power of the optical module on the interface. When the transmit or receive power of an optical module exceeds the upper alarm threshold or falls below the lower alarm threshold, an alarm is generated.
