request system software rollback (Junos OS Evolved)

date_range 19-Nov-23
arrow_backward
arrow_forward

Syntax

content_copy zoom_out_map
request system software rollback reboot
<no-validate>
<package-name version>
<with-old-snapshot-config>

Description

Use this command to revert to the last successfully installed package before the last-issued request system software (add | delete) command. By default, once the software is rolled back, the device uses the current configuration file. You can use this command on either Routing Engine in a dual-Routing Engine system.

On Junos OS Evolved, the reboot option is required in order to complete the rollback.

Options

package-name version

Select any installed version for the rollback. The request system software rollback operational mode command uses the version instead of the package-name. You can see the available versions by using the show system software list operational mode command. If you do not specify the version, the system rolls back to the default rollback version (the one with the '<' before it on the show system software list command output). You can specify any previous Junos OS Evolved release as long as it is neither the one that is currently running nor the rollback version.

no-validate

Do not check compatibility with the current configuration.

Default: validate

reboot

(Optional) Reboot to complete the rollback. If you do not specify the reboot option, then when this command completes, you need to issue the request system reboot operational mode command to reboot the system to finish the rollback process.

with-old-snapshot-config

(Optional) Rolls back the system to the specified version with the old snapshot of the configuration used in that version. Otherwise, the rollback, by default, takes the current configuration.

Required Privilege Level

maintenance

Output Fields

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