    Hi all,

    How to check about when junos upgrade and what previous version etc... Are there cli command to check this historical upgrade check?

    On SRX, try "show system software backup".  And on EX, "show system snapshot media internal".  Hope that answers your query.

     

    Example:

    root> run show version

    Thanks reply....

    With the command of show system snapshot media internal, we can see when snapshoot has been taken but it doesn't say when new version has been installed? Snapshot and upgrade should be different thing, isn't it?

    What I want to see is to perform cli to see old/previosu one version of junos and when the update was done and who did?

    Hi Arix,

    One way to check the release history is to check the inventory file as shown below


    show log inventory | match release
    Dec 14 16:43:28 CHASSISD release 16.1R3-S1.3 built by builder on 2016-12-14 21:09:49 UTC
    Dec 7 04:45:35 CHASSISD release 18.4R1.2 built by builder on 2018-11-24 09:54:56 UTC

    To check who did the software upgrade or downgrade, you need to check the interactive-logs history .

    Regards,
    Jibu

    Hi Arix,

     

    There is a separate log to keep track of Junos installation, it will let you know at what time Junos upgrade was initialized and the type of Junos upgrade that was performed. 

     

    user@host> show log install

    user@host> show log install.0.gz

     

    Let me know if you've any further queries.

    Hi,

     

    Here is another way to check the current and previous version, in case log files have got overwritten and software backup has been deleted.

     

    root@srx% ls -l /var/sw/pkg/
    total 1381636
    -rw-r--r--  1 root  wheel  707195118 Jul 14 15:19 junos-srxmr-15.1X49-D130.6-domestic-signed.tgz   << current version
    -rw-r--r--  1 root  wheel         40 Jul 14 15:16 rollback

     

    root@srx% cat /var/sw/pkg/rollback 
    JUNOS Software Release [15.1X49-D140.3]   << rollback version

     

    To check who did the upgrade we would need to rely on the interactive logs or external syslog provided they go that far back.

    show log interactive | match "request system software"
    show log interactive.0.gz | match "request system software"
    and so on...
