How To View Optical Transceiver Information On H3C Switches

Time: 2023-06-06
        Optical transceivers are widely applied in switches, routers, network cards and other communication equipment. Querying transceiver parameters helps monitor real-time operation and troubleshoot link faults efficiently.
        We connect Moduletek QSFP-40G-LR4 transceiver to H3C S6820 switch, and demonstrate how to view port status and transceiver details on H3C devices.

1. Port Link & Transceiver Working Status
        Run command:
            display interface interface-type interface-number
        It displays port negotiation speed, transceiver type, link status (UP indicates normal link) and traffic statistics for fault analysis.
        Note: interface-type interface-number represents port type and port ID. Run display interface brief to view all port information. The switch will show details of all ports without input parameters.

2. Transceiver Identification Information
        Run command:
            display transceiver interface <interface-type> <interface-number>
        It queries transceiver specifications including model, wavelength, transmission distance and manufacturer data stored in module EEPROM.
3. Transceiver DDM Diagnostic Data & Thresholds
        Run command:
            display transceiver diagnosis interface <interface-type> <interface-number>
        It presents real-time DDM values and alarm threshold ranges. Check TX/RX optical power, temperature and bias current to verify operating status of transceivers on both ends.
        Moduletek optical transceivers are highly compatible with all H3C switch models. Welcome to inquire and purchase.
