Description
Display the current time and information about how long the router or switch, router or switch software, and routing protocols have been running.
Time values computed from differences in timestamps can vary due to the insertion or deletion of leap-seconds between them.
The show system uptime command is a little different in how it displays output in Junos
OS Evolved. The show system uptime command by itself shows
system-wide uptime information. Use the show system uptime node node-name command to see node-specific uptime information,
where node-name can be re0 |
re1 | fpc0 | all.
Options
| none | Show time since the system rebooted and processes started. |
| all-chassis | (TX Matrix routers and TX Matrix Plus routers only) (Optional) Show time since the system rebooted and processes started on all the routers in the chassis. |
| all-lcc | (TX Matrix routers and TX Matrix Plus routers only) (Optional) On a TX Matrix router, show time since the system rebooted and processes started for all T640 routers (or line-card chassis) connected to the TX Matrix router. On a TX Matrix Plus router, show time since the system rebooted and processes started for all connected T1600 or T4000 LCCs. |
| all-members | (EX4200 switches and MX Series routers only) (Optional) Show time since the system rebooted and processes started on all members of the Virtual Chassis configuration. |
| director-group name | (QFabric systems only) (Optional) Show time since the system rebooted and processes started on the Director group. |
| infrastructure name | (QFabric systems only) (Optional) Show time since the system rebooted and processes started on the fabric control Routing Engine and fabric manager Routing Engine. |
| interconnect-device name | (QFabric systems only) (Optional) Show time since the system rebooted and processes started on the Interconnect device. |
| invoke-on | (MX Series routers only) (Optional) Display the time since the system rebooted and processes started on the primary Routing Engine, backup Routing Engine, or both, on a router with two Routing Engines. |
| lcc number | (TX Matrix routers and TX Matrix Plus routers only) (Optional) On a TX Matrix router, show time since the system rebooted and processes started for a specific T640 router that is connected to the TX Matrix router. On a TX Matrix Plus router, show time since the system rebooted and processes started for a specific router that is connected to the TX Matrix Plus router. Replace number with the following values depending on the LCC configuration:
|
| local | (EX4200 switches and MX Series routers only) (Optional) Show time since the system rebooted and processes started on the local Virtual Chassis member. |
| member member-id | (EX4200 switches and MX Series routers only) (Optional)
Show time since the system rebooted and processes started on the specified
member of the Virtual Chassis configuration. For EX4200 switches,
replace |
node node-name |
(Junos OS Evolved only) (Optional) Display
uptime information for the specified node. When |
| node-group name | (QFabric systems only) (Optional) Show time since the system rebooted and processes started on the Node group. |
| scc | (TX Matrix routers only) (Optional) Show time since the system rebooted and processes started for the TX Matrix router (or switch-card chassis). |
| sfc number | (TX Matrix Plus routers only) (Optional) Show time since the system rebooted and processes started for the TX Matrix Plus router. Replace number with 0. |
Additional Information
By default, when you issue the show system uptime command on the primary Routing Engine of a TX Matrix router or a
TX Matrix Plus router, the command is broadcast to all the primary
Routing Engines of the LCCs connected to it in the routing matrix.
Likewise, if you issue the same command on the backup Routing Engine
of a TX Matrix or a TX Matrix Plus router, the command is broadcast
to all backup Routing Engines of the LCCs that are connected to it
in the routing matrix.

Starting in Junos OS Evolved 19.1R1 release, the show system
uptime output displays only the System booted and System-wide users information. The output does not display
the details such as Current time, System booted, Protocols started, and Last configured parameters. To see node-specific uptime information, use the node option.
