How To View Port Status And Optical Module Information On Extreme Switches

Time: 2024-01-03
        When optical modules are installed on switches, it is necessary to read internal module parameters to monitor operating status, including link connectivity, real-time transmit/receive optical power, and temperature. Verifying module identification also helps check coding compatibility between the module and the switch.
        This document uses the Moduletek SFP-10G-LR-BIDI optical module installed on an Extreme X690-48x-2q-4c switch as an example to demonstrate how to view port status and optical module information on Extreme switches.

1. View Port & Optical Module Status
        Run the following command to view interface configuration and status:
          show port <port_number> configuration
        Add no-refresh to disable automatic screen refresh:
          show port <port_number> configuration no-refresh
        The output includes:
        • Interface speed and duplex mode
        • Optical module type
        • Link status (Active is required for normal operation)
        Note:
        • <port_number> is the physical port number labeled on the switch panel.
        • Omit the port number to display information for all ports.
2. Query Module Identification & DDM Information
        To view detailed module identity and digital diagnostic monitoring (DDM) data, run:
          show ports <port_number> transceiver information detail
        The command returns two key sections:
        • Module identification: module type, part number, vendor name, serial number, operating wavelength, etc.
          Note: Media Type may show Unsupported for non-Extreme-certified modules.
        • DDM diagnostics: real-time values of temperature, voltage, Tx/Rx optical power, along with alarm thresholds.
          A status of Normal indicates all diagnostic parameters are within the valid range.
