How To Read Optical Module Information On H3C Switches

Time: 2023-06-06
        Optical modules are widely used in switches, network cards, routers, and other communication equipment. Reading optical module information during use helps understand its real-time operating status, allowing you to locate the cause of link abnormalities more quickly.
        The following uses the Moduletek QSFP-40G-LR4 module connected to an H3C S6820 switch as an example to introduce how to read information of the connected optical module on an H3C switch.

1. Check Optical Module Status
        Run the following command to view detailed interface and optical module status:
        show interface <interface-type> <interface-number>
        The output includes interface rate, module type, link state (a UP state is required for normal module operation), and statistical data, all of which facilitate troubleshooting.
        Note: <interface-type> <interface-number> indicates the type and number of the interface where the optical module is installed.
                   You can run the following command to view interface types, then confirm the interface number from the switch panel.
                   show interface brief
                   If the interface type and number are unknown, you can run the command without parameters to display information for all interfaces.
2. View Optical Module Identification Information
        Run the following command to read identification information for the optical module on the target interface:
        show transceiver interface <interface-type> <interface-number>
        The output includes module type, wavelength, transmission distance, vendor name, and more, retrieved from pre-programmed data in the optical module.
3. Check Optical Module DDM Detection Data
        Run the following command to view the Digital Diagnostic Monitoring (DDM) data of the optical module:
        show transceiver diagnosis interface <interface-type> <interface-number>
        The output provides real-time diagnostic metrics and their corresponding threshold ranges. You can verify normal operation by monitoring key parameters such as transmit optical power, receive optical power, temperature, and bias current.
