request system reboot (Junos OS Evolved)

date_range 08-Dec-23
arrow_backward
arrow_forward

Syntax

content_copy zoom_out_map
request system reboot 
<at time>
<in minutes> 
<message "text">

Description

Reboot the entire system (all nodes).

To reboot a single node, use the request node reboot command instead.

Options

none

Reboot the software immediately.

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.

  • 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. The minimum value is 1. This option is an alias for the at +minutes option.

message "text"

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

Additional Information

Starting in Junos OS Evolved 23.4R1, when rebooting a system with this command, the Layer 2 applications l2ald, l2ald-agent, l2cpd, and l2cpd-agent are initialized and started only if any of the following configuration hierarchy levels contain any configuration statements:

  • [edit interface interface-name unit number family ethernet-switching]

  • [edit vlans]

  • [edit routing-instance instance-name instance-type virtual-switch]

  • [edit routing-instance instance-name instance-type mac-vrf]

  • [edit protocols l2-learning]

Additionally, l2cpd, and l2cpd-agent are initialized and started if the [edit protocols lldp] hierarchy level contains any configuration statements.

As a result of this change, if your configuration already contains these configuration statements and you then delete all of the above configuration statements, these Layer 2 applications stop running.

Required Privilege Level

Output Fields
