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.

Options
| none |
Display standard information about the hostname and version of the software running on the router or switch. |
| brief | detail |
(Optional) Display the specified level of output. |
| all-members |
(EX4200 switches and MX Series routers only) (Optional) Display standard information about the hostname and version of the software running on all members of the Virtual Chassis configuration. |
| component all |
(QFabric systems only) (Optional) Display the host name and version information about the software running on all the components on the QFabric system. |
| component component-name |
(QFabric systems only) (Optional) Display the host name and version information about the software running on a specific QFabric system component. Replace component-name with the name of the QFabric system component. The component-name can be the name of a diagnostics Routing Engine, Director group, fabric control Routing Engine, fabric manager Routing Engine, Interconnect device, or Node group. |
| local |
(EX4200 switches and MX Series routers only) (Optional) Display standard information about the hostname and version of the software running on the local Virtual Chassis member. |
| member member-id |
(EX4200 switches and MX Series routers only) (Optional) Display standard
information about the hostname and version of the software running on
the specified member of the Virtual Chassis configuration. For EX4200
switches, replace |
| node (all | node-name) |
(Optional) Display version information for the specified node or all nodes. |
| scc |
(TX Matrix routers only) (Optional) Display the hostname and version information about the software running on the TX Matrix router (or switch-card chassis). |
| lcc number |
(TX Matrix routers and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display the host name and version information about the software running on for a specified T640 router (line-card chassis or LCC) that is connected to the TX Matrix router. On a TX Matrix Plus router, display the host name and version information about the software running for a specified T1600 or T4000 router (LCC) that is connected to the TX Matrix Plus router. Replace number with the following values depending on the LCC configuration:
|
| primary |
(SRX Series only) Display the software version on the primary node. |
| sfc number |
(TX Matrix Plus routers only) (Optional) Display the hostname and version information about the software running on the TX Matrix Plus router (or switch-fabric chassis). Replace number with 0. |
Additional Information
By default, when you issue the show version command on a TX Matrix
or TX Matrix Plus primary 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) primary 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.
