Description

Reboot the software.

Options

none

Reboot the software immediately.

all-chassis

(TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, reboot all T640 routers (or line-card chassis) connected to the TX Matrix router. On a TX Matrix Plus router, reboot all T1600 routers (or line-card chassis) connected to the TX Matrix Plus router.

all-lcc

(TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, reboot all T640 routers (or line-card chassis) connected to the TX Matrix router. On a TX Matrix Plus router, reboot all T1600 routers (or line-card chassis) connected to the TX Matrix Plus router.

all-members

(EX4200 switches only) (Optional) Reboot all members of the Virtual Chassis configuration.

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.

lcc number

(TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, the number of a T640 router that is connected to the TX Matrix router. On a TX Matrix Plus router, the number of a T1600 router that is connected to the TX Matrix Plus router. Replace number with a value from 0 through 3.

local

(EX4200 switches only) (Optional) Reboot the local Virtual Chassis member.

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 routers only.)

media (external | internal)

(EX Series switches only) (Optional) Reboot the boot media:

• external—Reboot the external mass storage device.
• internal—Reboot the internal flash device.

member member-id

(EX4200 switches only) (Optional) Reboot the specified member of the Virtual Chassis configuration Replace member-id with a value from 0 through 9.

message "text"

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

other-routing-engine

(Optional) 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.

partition

(TX Matrix Plus routers only) (Optional) Reboot using the specified partition on the boot media. This option has the following suboptions:

• 1—Reboot from partition 1.
• 2—Reboot from partition 2.
• alternate—Reboot from the alternate partition.

scc

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

sfc number

(TX Matrix Plus routers only) (Optional) Reboot the Routing Engine on the TX Matrix Plus router (or switch-fabric chassis). If you issue the command from re0, re0 is rebooted. If you issue the command from re1, re1 is rebooted. Replace number with 0.

slice slice

(EX-series switches only) (Optional) Reboot a partition on the boot media. This option has the following suboptions:

• 1—Power off partition 1.
• 2—Power off partition 2.
• alternate—Reboot from the alternate partition.

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 TX Matrix or TX Matrix Plus router, 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.

List of Sample Output

Output Fields

When you enter this command, you are provided feedback on the status of your request.

Sample Output

Reboot the system ? [yes,no] (no)

Reboot the system ? [yes,no] (no) yes

shutdown: [pid 186]
*** System shutdown message from root@berry.network.net ***
System going down at 23:00

The following example, which assumes that the time is 5 PM (17:00), illustrates three different ways to request the system to reboot in two hours:

To reboot the system at 1:20 AM, enter the following command. Because 1:20 AM is the next day, you must specify the absolute time.

request system reboot at 120
Reboot the system at 120? [yes,no] (no) yes
