    I have been trying to figure out which versions of Junos are Junos Evolved.
    I'm not trying to use any of the advanced features, I just want to know if any of my EX switches or SRX firewalls are vulnerable to some of the recent security issues that affect Junos Evolved.

    Can anyone suggest which versions are running Junos Evolved?

    I agree this is confusing on where it is deployed.  There are limited platforms and versions.

    I have confirmed with my sales engineer that Junos evolved is NOT on ex or srx at this time.

    'show version' should include an 'EVO' string if it is junos-evo:

    I believe it's mainly some PTX & QFX platforms that support EVO at this point.

    Thanks, I definitely don't have 'EVO' listed in show version

    Hi Luke,

    currently there are no EX or SRX devices with Junos Evolved available.
    There are only very few PTX, QFX (QFX5220, QFX5130) and ACX7100 with Evolved available.

    Thanks, that makes sense. Unfortunately, I don't think the documentation is clear on this point.

    No, EX and SRX seem not to be supported by Junos Evoled.
