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:

  

• 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
...truncated... 
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
02650720100000001
