[vSRX] License auto update may fail if it was originally generated through LMS, then renewed through JAL



Article ID: KB32135 KB Last Updated: 07 Sep 2017Version: 1.0

This article addresses the following:

  1. Ho​w to get Software Serial Number (SSN) from vSRX.

  2. What differences will there be in SSN if the license is generated using LMS or JAL (Juniper Agile license)?

  3. What is the impact of license renewal through JAL that was originally generated through LMS?


After renewing a license through JAL, which was originally generated through LMS, 5 more alpha numeric characters are added to the SSN. This may cause auto update to fail.


The Software Serial Number (SSN) can be obtained with the command, 'show system license'.

Example snippets from three different outputs:

  1. An evaluation license of 60 days:

      Licenses installed:
      License identifier: E420588955
      License version: 4
      Software Serial Number: 20150625 <-- SSN
      Customer ID: vSRX-JuniperEval
        Virtual Appliance - Virtual Appliance  
          count-down, Original validity: 60 days

  2. License generated from LMS:

      License identifier: JUNOS909778 
      License version: 4 
      Software Serial Number: 91730A00261410 <--SSN 
      Customer ID:LABJNPR LAB 
        Virtual Appliance - Virtual Appliance    
          date-based, 2017-04-04 00:00:00 UTC - 2018-04-05 00:00:00 UTC

  3. License generated from Juniper Agile License (JAL):

      License identifier: JUNOS680030575
      License version: 4
      Software Serial Number: SUB00019177258-d7hi6 <--SSN
      Customer ID: XYZ CORPORATION
        Virtual Appliance - Virtual Appliance
          date-based, 2017-06-22 00:00:00 UTC - 2018-06-21 00:00:00 UTC    

In case the original LMS license is renewed through JAL, manually update the vSRX license. Refer to KB16675 - SRX Getting Started - Install license for Antivirus, Web Filter, IDP, or Antispam
