Syntax

Syntax (Routing Matrix)

Release Information

Command introduced before JUNOS Release 7.4.

other-routing-engine option added in JUNOS Release 8.0.

Description

Reboot the software.

Options

none — Reboot the software immediately.

all-lcc — (Routing matrix only) (Optional) Reboot all T640 routing nodes (or line-card chassis) connected to the TX Matrix platform.

lcc number — (Routing matrix only) (Optional) Number of a T640 routing node that is connected to a TX Matrix platform. Replace number with a value from 0 through 3.

scc — (Routing matrix only) (Optional) Reboot the Routing Engine on the TX Matrix platform (or switch-card chassis). If you issue the command from re0, re0 is rebooted. If you issue the command from re1, re1 is rebooted.

other-routing-engine — Reboot the other Routing Engine from which the command is issued. For example, if you issue the command from the master Routing Engine, the backup Routing Engine is rebooted. Similarly, if you issue the command from the backup Routing Engine, the master Routing Engine is rebooted.

at time — (Optional) Time at which to reboot the software, specified in one of the following ways:

• now—Stop or reboot the software immediately. This is the default.
• +minutes—Number of minutes from now to reboot the software.
• yymmddhhmm—Absolute time at which to reboot the software, specified as year, month, day, hour, and minute.
• hh:mm—Absolute time on the current day at which to stop the software, specified in 24-hour time.

in minutes — (Optional) Number of minutes from now to reboot the software. This option is an alias for the at +minutes option.

media (compact-flash | disk | removable-compact-flash | usb) — (Optional) Boot medium for next boot. (The options removable-compact-flash and usb pertain to the J-series routing platform only.)

message "text" — (Optional) Message to display to all system users before stopping or rebooting the software.

Additional Information

Reboot requests are recorded in the system log files, which you can view with the show log command (see show log). Also, the names of any running processes that are scheduled to be shut down are changed. You can view the process names with the show system processes command (see show system processes).

On a routing matrix, if you issue the request system reboot command on the master Routing Engine, all the master Routing Engines connected to the routing matrix are rebooted. If you issue this command on the backup Routing Engine, all the backup Routing Engines connected to the routing matrix are rebooted.

Note: To reboot a router that has two Routing Engines, reboot the backup Routing Engine (if you have upgraded it) first, and then reboot the master Routing Engine.
