Related to Paloalto VM instance type change

L3 Networker

Dear Team,

 

I have a question while testing.

 

If I'm wrong, anyone please feel free to leave a comment.

 

1. Check if an issue occurs in the service traffic processing part when changing the instance type
> Since there is no change in the settings, traffic processing is normal, but the throughput changes depending on the instance.
> ex) m5.2xlarge(vCPU 8, 16G) : 6Gbps > m5.xlarge(vCPU 4, 9G) : 3Gbps

 

2. Confirmation of License Changes
> Paloalto licenses are identified by a unique CPU-ID and UUID.
> Since the CPU-ID changes when the instance type is changed, it is essential to deactivate the license before changing the instance type.
> If I apply the license again after changing the instance, it can be used normally.

 

3. Setting change part of Panorama that is linked with the firewall
> When re-applying the license, a new S/N is created, so there is no need to change the settings in the firewall. However, in Panorama, it is necessary to re-link with the changed S/N of the firewall.

If anyone has experienced any of the above symptoms or knows a solution, please share with me.

 

Thanks in advance,

Kyungjun,

Hi @CHOE-KyungJun ,

 

Are you saying that you are having issues with licensing after recreating a VM? Are you seeing a valid license when you type in the command "show system info" on the new VM?

Thank you for your reply

 

I didn't recreate the VM. I simply changed the instance type.

 

The link below confirms that the license needs to be deactivated before changing the Cloud instance type.

https://docs.paloaltonetworks.com/pan-os/10-2/pan-os-upgrade/upgrade-the-vm-series-firewall/upgrade-...

  • In a private or public cloud deployment, if your firewall is licensed with the BYOL option, you must deactivate your VM before you change the instance type or VM type. Upgrading the model or instance changes the UUID and CPU ID, so you must apply the license when the.

However, in actual testing, CPU-ID does not change and S/N does not change either.

I would like to know why the symptoms are occurring.

AWS(M5.2xlarge > M5.xlarge) / Azure(DS3_v2 > D8s_v3)
