restart (Junos OS Evolved)

date_range 19-Nov-23

arrow_forward

Syntax

content_copy zoom_out_map
restart application-name
<gracefully | immediately | soft>

Description

Restart a Junos OS Evolved process.

CAUTION:

Never restart a software process unless instructed to do so by a customer support engineer. A restart might cause the router or switch to drop calls and interrupt transmission, resulting in possible loss of data.

For Junos OS Evolved, the restart command also triggers a restart of the dependent applications (apps). To inform you which dependent apps restarted, the following message appears in the log whenever you use the restart command:

App restarting <app name>. Related apps that may be impacted - <related-app name> . For example: Jan 14 11:42:08 RE0 sysman[5100]: SYSTEM_APP_RESTARTING_WITH_RELAPPS_EVENT: App restarting re0-ifmand. Related apps that may be impacted - aggd

Starting in Junos OS Evolved Release 20.1R1, if you specify the restart app-name command and the application is not supposed to run on the platform, the error message is as follows:

content_copy zoom_out_map
user@device> restart fabspoked-pfe
Restart failed for fabspoked-pfe on node re0. Application is not running.

The restart command expands all application names, including applications not required for the current platform. Therefore, you could try to restart an application that is not running for the current platform. This error message communicates that the restart failed because the application was not running on the system.

Options

application-name Specify the name of the application you want to restart. Use the show system applications operational mode command for information about what applications are running.
none

Same as gracefully.

gracefully

(Optional) Gracefully restart the software process.

immediately

(Optional) Immediately restart the software process.

soft

(Optional) Re-read and reactivate the configuration without completely restarting the software processes. For example, BGP peers stay up and the routing table stays constant. Omitting this option results in a graceful restart of the software process.

Required Privilege Level

reset

Output Fields

When you enter this command, the system provides feedback on the status of your request.

Sample Output

restart interface-control (Junos OS Evolved)

content_copy zoom_out_map
user@host> restart interface-control
interface-control restart requested
Restarted aggd on re0
Restarted ifmand on re0
