Panorama with pan-os-python API

L0 Member

Hi,

 

I have three firewalls added to a device group in Panorama. I am accessing Panorama via pan-os-python API and from there I want to fetch some device group "MyDG" and then delete one of the firewalls from panorama based on the hostname of the firewall. I can see the hostnames set/configured in Panorama > Managed Devices > Summary in the GUI but when I try to fetch the information for any of my firewall devices via Panorama object through the API I get this error about hostname. I have tried other methods for this "fw0" object too and it throws the same error. Probably I am missing something.

 

Can someone pls guide what am I doing wrong or is it some bug?

 

>>> pano
<Panorama 202.24.62.93 0x10adc3d30>
>>> devices = pano.refresh_devices(include_device_groups=False)
>>> devices
[<Firewall '007955000319973' 'vsys1' at 0x10ad29180>, <Firewall '007955000319994' 'vsys1' at 0x10ad2bca0>, <Firewall '007955000399952' 'vsys1' at 0x10a5af640>]
>>> fw0 = devices[0]
>>> fw0.serial
'007955000319973'
>>> fw0.refresh()

Have you tried adding the Firewall object to the Panorama object?

 

Order of operations here:

  1. create an object to represent our Panorama instance connection
  2. use this Panorama object to retrieve a list of our devices, storing them in a list
  3. select the correct index for your firewall within this list
  4. add the Firewall object to the Panorama object as a child
  5. execute your refresh method on the firewall object

You had all but the 4th step, as the error message presented:

panos.errors.PanDeviceNotSet: No Panorama set for object tree

 

Here is an example output:

Let me know if you're still running into an issue,
