KB 471506 - How to Fetch Transceiver Details of All Ports in an InfiniBand QM9700 Switch


Overview

On NVIDIA/Mellanox QM9700 InfiniBand switches, you may need to view the transceiver details (e.g., vendor, part number, and serial number) for connected optical modules or cables. This can be useful for troubleshooting, inventory tracking, or validating optics compatibility.
The QM9700 NOS provides CLI commands that allow you to retrieve transceiver details for all ports at once or for a specific port.

Prerequisites

  • Access to the QM9700 switch CLI (via SSH or console).

  • Administrative privileges.


Fetching Transceiver Details

1. All Ports (Bulk View)

To display transceiver details for all InfiniBand ports:

  1. show interfaces ib transceiver

This will output a table including:

  • Interface/Port

  • Vendor Name

  • Part Number

  • Serial Number

  • Type (QSFP, AOC, DAC, etc.)

  • Wavelength / Length

  • Digital Optical Monitoring (DOM) data: Temperature, Voltage, TX/RX Power

2. Individual Port

If you want to check details for a specific InfiniBand port, use:

  1. show interfaces ib <port_number> transceiver

Example:

  1. show interfaces ib 1/5 transceiver

This will display the same set of details but only for the specified port.
