    Dear Sir/Madam I have a Switch EX3300 using firmware 12.3R3.4. But there is some errors CVE existed in this version, so I want to update it to 12.3R12. However,in my equipment has options the layer 3 is routing. Therefore I just wonder that whether layer 3 functions are gonna be lost after this updating or not? And is there any impact to the license of equipment? , THank you very much

    Hi Folks,

    Are you planning to upgrade the Junos or only the FPC Firmware?


    You should not lose layer 3 function in either way. License should not get affected in general. Proactively you can take a backup of the license to a text file.


    show system license keys > /var/tmp/license.txt


    and add it later with ‘request system license add’ cli. Use ‘show system license’ to verify the license once added.

    I've never seen an EX upgrade that affects L3 or any other config, or licenses.  I would recommend stay with 12.3 at this time for EX3300.
