How to check the optical power of a Huawei switch

To check optical power levels on a Huawei switch interface, use the command display interface transceiver verbose to retrieve detailed information about the optical module, including current RX and TX power levels.Steps to Check Optical Power LevelsAccess the Command Line Interface (CLI): Connect to your Huawei switch using a terminal emulator or console connection.Use the Command: Enter the following command to display the optical power levels for a specific interface:BashCopydisplay interface [interface-type] [interface-number] transceiver verbose Replace [interface-type] with the type of interface (e.g., GigabitEthernet, TenGigabitEthernet).Replace [interface-number] with the specific interface number (e.g., 1/0/1).Review the Output: The command will provide detailed information about the optical module, including:Current RX Power (dBm): Indicates the received optical power.Current TX Power (dBm): Indicates the transmitted optical power.Thresholds: Displays the high and low thresholds for both RX and TX power, which can help identify potential issues if the values exceed these thresholds .Example CommandFor example, to check the optical power on a Gigabit Ethernet interface 1/0/1, you would enter:BashCopydisplay interface GigabitEthernet1/0/1 transceiver verbose Additional CommandsTo view a summary of all interfaces and their optical module status, you can use:BashCopydisplay interface brief For more detailed diagnostics, you can also use:BashCopydisplay transceiver interface [interface-type] [interface-number] verbose This command provides additional diagnostic information about the optical module, including temperature, voltage, and bias current . By following these steps, you can effectively monitor and troubleshoot optical power levels on your Huawei switch interfaces.
