Layer 3 sub interfaces on Hyper-V

L0 Member

Hi all,

I am trying to get Palo Alto VM series (10.2.3) to work with layer 3 sub interfaces on Hyper-V (2022).
I configured interface/subinterface from the documentation (
I also tried it with removing the ip.adr
I also tried setting the vSwitch to trunk mode on the Hyper-V host with
Set-VMNetworkAdaptervlan -VMName PA -VMNetworkAdapterName "PA-LAN-Switch" -Trunk -AllowedVlanIdList "1-7" -NativeVlanId 0

I can ping between vms on the vlan 7 ... but I cannot ping the PA IP (
If I remove the subinterface and the vlan tagging in the Hyper-V Host I can ping


Any help would be appreciated,

Best Regards

Here is how I have set this up in the past. However I make my physical interfaces layer2, trunk the vlans, and then make layer3 vlan interfaces on the PAN. This I feel allows for more control and forces all traffic to pass through the PAN. 


Then on the Hyper-V side make sure you tag the vlans appropriately.  When you create a VM, make sure you use static MAC's and also have the VM tag the network packets. The interfaces are not pingable by default. You need to configure a management profile that allows pings, then attach it to the interface. You will also need security policies to allow the ping.


Hope this helps.


Thank you for your advice.

I tried Layer 2 with




and still no luck. 
I used 

Set-VMNetworkAdapterVlan -VMName web01 -VMNetworkAdapterName web01-LAN-Switch -Access -VlanId 7
tried static MACs ... and even 

sudo ip link add link eth2 name eth2.7 type vlan id 7
I created a ping managment profile and added a any/any for icmp/ping policy.
For some reason I can ping from the hvper-v host (when added to the vlan 7) the web01 but not the Palo Alto Interface.

Any Ideas?

Best Regards

I would say the PAN config is correct. Might want to recheck the Hyper-V side:

If using a Teamed interface make sure its tagged:


Then on the VM settings:


Sorry I cant find my notes from when I built everything. It was a long time ago.


Hope this helps.

I have an almost identical setup. It was working great on 10.1.3 and 10.1.8 for many months. Once I upgraded to the 10.2.0 and above line (I am on 10.2.3-h4 now) Vlan traffic will not pass my sub-interfaces. The arp's are not passing and getting dropped due to vlan tags not getting appended to the packets it appears. It must somehow be related to Hyper-V. We are gathering data in my TAC case and they said the fix will be in 10.2.4 when that version comes out.

I can confirm that the new version 10.2.4 fixes this issue now.

and 11.0.1

I am facing this issue on 11.0.. will try to update to 11.0.1 to see if it fixes the issue
