[QFX] How to get Director Group (DG) device serial number



Article ID: KB36788 KB Last Updated: 01 Jun 2021Version: 1.0

This article explains how to retrieve Qfabric Director Group device serial number.


I need the DG device serial number to open a JTAC Service Request (case) or process RMA while the DG device is defective.


There are several methods to get the serial number for a DG device.

  • Directly from the physical DG device

    The serial number ID label is located on the back of the chassis on a QFX3100 Director device:

    Locate DG Serial Number

  • From CLI command
    DG serial number can be obtained from the CLI command, 'show fabric administration inventory' if the Qfabric system runs normally.

    user@device> show fabric administration inventory                   
    Item                    Identifier              Connection      Configuration
    Director group
      DG0                  02650720100000000        Connected                     
      DG1                  02650720100000001        Connected   
  • From DG shell prompt

    If DG is in abnormal status and you cannot use the CLI command, the following shell command can be used to get the DG's serial number:

    dmidecode -s system-serial-number

    Example command output to get dg1's serial number from dg1 shell prompt:

    [user@dg1 ~]# dmidecode -s system-serial-number
