request system software sync
Syntax
request system software sync (current | rollback | all-versions)
Description
Use this command on the primary Routing Engine of a system to synchronize the software and configurations from the primary Routing Engine to the other nodes and reboot the other nodes. The configurations are synchronized even if the images are identical. If specified on the backup Routing Engine, the command fails.
The request system software sync command is only supported on
PTX Series and QFX Series devices that have two Routing Engines.
Options
current | rollback | all-versions |
Specify which software version (current, rollback, or all versions) to sync to the other node:
|
Additional Information
For the all-versions option, the synchronization proceeds as
follows:
- All versions are deleted on the other node, except for the current version.
- The current and rollback images and configurations are copied from the primary Routing Engine to the other node. Even if the software versions match, the configuration is copied and the software proceeds to the next image.
- Any other versions and configurations are copied from the primary Routing Engine to the other node.
- If the current version on the other node is not the same as current on the primary Routing Engine, then the other node is rebooted after warning the user.
The request system software sync all-versions command is successful
if the first two steps of the synchronization are successful. If step 3 fails, a
warning message is displayed. To make the versions match, you can delete the extra
versions using the request system software delete operational mode
command.
To see what the software versions are available on the device, use the show
system software list command.
If an Routing Engine that has a different software version is inserted into the
system, the Routing Engine is kept outside the system and a software mismatch alarm
is generated, which specifies the Routing Engine name and the version of software on
that Routing Engine, similar to the following: Software Version Mismatch on
re1:junos-evo-install-ptx-x86-64-20.4R2.6-EVO. To clear this alarm, use
the request system software sync all-versions command to
synchronize the software. Once the new Routing Engine comes back up, it joins the
system.

For the current option, before you switch control to a
newly-inserted Routing Engine, ensure all images are synchronized to the
newly-inserted Routing Engine by using the output from the show system
software list operational mode command to compare the images installed
on both Routing Engines and make sure they are the same. You must make sure that the
system has finished synchronizing all of the images in the background before you
switch control to the newly- inserted Routing Engine to ensure that the
newly-inserted Routing Engine does not remove any images from the existing Routing
Engine.
