Description

Display the hostname and version information about the software running on the router or switch.

Beginning in Junos OS Release 13.3, the show version command output includes the Junos field that displays the Junos OS version, including any selective upgrade (JSU) packages, running on the device. This field provides a consistent means of identifying the Junos OS version, rather than extracting that information from the list of installed sub-packages.
