Release Information
Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 9.0 for EX Series switches.
sfc option introduced for the TX Matrix Plus router in Junos OS Release 9.6.
Command introduced in Junos OS Release 11.1 for the QFX Series.
Command introduced in Junos OS Release 15.1X54-D20 for ACX5048 and ACX5096 Routers.
node option introduced in Junos OS Evolved Release 18.3R1.
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 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.
The output for the show version command for Junos OS Evolved includes a Junos Package field that indicates the installation package name. From the prefix of this package name, you can decode which Junos OS architecture the device is running.
Table 1: Common Package Prefixes for Junos OS
Junos OS Package Prefix | Junos OS Architecture |
|---|---|
jinstall-* | Junos OS for M Series, MX Series, T Series, TX Matrix, and TX Matrix Plus routers |
junos-install-* | Junos OS based on an upgraded FreeBSD kernel instead of older versions of FreeBSD |
junos-vmhost-install-* | Junos OS with upgraded FreeBSD on a VM Host |
junos-evo-install-* | Junos OS Evolved |
Options
Replace number with the following values depending on the LCC configuration:
0 through 3, when T640 routers are connected to a TX Matrix router in a routing matrix.
0 through 3, when T1600 routers are connected to a TX Matrix Plus router in a routing matrix.
0 through 7, when T1600 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.
0, 2, 4, or 6, when T4000 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.
Additional Information
By default, when you issue the show version command on a TX Matrix or TX Matrix Plus master Routing Engine, the command is broadcast to all the T640 (in a routing matrix based on a TX Matrix router) or T1600 or T4000 (in a routing matrix based on a TX Matrix Plus router) master Routing Engines connected to it. Likewise, if you issue the same command on the TX Matrix or TX Matrix Plus backup Routing Engine, the command is broadcast to all the T640 (in a routing matrix based on a TX Matrix router) or T1600 or T4000 (in a routing matrix based on a TX Matrix Plus router) backup Routing Engines that are connected to it.

The following output is from the MX240 Router and shows the Junos field introduced in Junos OS 13.3. Depending on the platform running Junos OS 13.3, you might see different installed sub-packages, but the Junos field is common across all platforms that run Junos OS 13.3 and later.
