HA Pair manual syncronization

L3 Networker

Good morning, I'm trying to understand the behavior with this command  request high-availability sync-to-remote running-config .  I have a HA active/passive pair that I had some config sync issues after an OS upgrade.  

If I want to push the active running configuration from my active device to my passive device, do I run this command from the active device or the passive device?  


I would assume I would be running it from the active device.


Please advise,


Thanks Dan

Oh along with this.  Currently the config sync link is missing from the HA widget on the dashboard.  Kinda strange.

I would verify your HA config first. However its best practice to sync from Active to Passive.

Thanks for the reply.  That helped.

I'm digging this one up as I'm now encountering the same issue I had the last time I did my PAN OS upgrade.  After I suspend preemptive in the HA settings. I suspend the local device, the passive device becomes active.  I install on newly passive device, I commit on the device  Once the device reboots, I have an unsyncronized pair. 



So, at this point I would like to copy the active running config from the active device to the passive device in an attempt to resync before continuing.


This is the command I'm running from the active device.  I'm just confused on the language they use. 

request high-availability sync-to-remote running-config
Executing this command will overwrite the candidate configuration on the peer and trigger a commit on the peer. Do you want to continue? (y or n)


In this instance will the candidate configuration of the remote device, aka the passive device will be over written by the current running config of the Active device?

Like what you see?
