Checking the Current Configuration and Candidate Software Compatibility
When you upgrade or downgrade JUNOS Software, we recommend that you include
the
validate option with the request system software add command to check that the
candidate software is compatible with the current configuration. By default, when
you add a package with a different release number, the validation check is done
automatically. For more information about the
request system software add command,
see the JUNOS System Basics and Services Command Reference .
Determining the JUNOS Software Version
To determine which software packages are running on the router and to get
information about these packages, use the
show version operational mode command
at the top level of the command-line interface (CLI).
NOTE: The show version command does not show the software category installed,
only the release number of the software.
