Which Version of TOS am I Using?

When lodging a support request or to determine which features are supported, you may need to check which version of TOS you are using. The version number is made up of 3 components, the version number (for example 21-2), the suffix (GA, HF, or RC), and the build number. Part of this information may be available only to Admin users.

There are several ways to determine your version, depending on which version you are using and which features you have access to:

In recent versions of TOS

  • In SecureTrack or SecureChange, in the top right corner click to view the version number

SecureTrack Users with Admin Privileges

Users with Admin privileges can do one of the following:

  • In TOS Classic:

    In SecureTrack, go to Settings > Administration > Status

  • For TOS Aurora :
    In SecureTrack, go to Admin > Status.

  • Use one of the following CLI Commands:

    If you are running TOS Aurora, run:

    sudo tos version

    If you are running TOS Classic, run:

    tos ver

    If you do not know which version of TOS you are using, try both of these commands, one of them will work.

Users without Admin Privileges

  • In SecureTrack or SecureChange, in the top right corner click > What Can I do on this Page.

    The version number is displayed at the top of the Knowledge Center
