Who Me Too'd this topic

I have configured a  couple of layer-3 subinterfaces on a aggregate, they are tagged as VLAN 700 and VLAN 800, in my cisco switch I have configured a trunk port that permits VLAN 700 and VLAN 800 to pass traffic across it. When plugged in, everything comes up just fine and I'm able to ping both interfaces etc etc.

As soon as I add a  native vlan to the trunk port the switch shuts it's interfaces down and stops passing traffic (due to a native vlan mismatch obviously) how do I configure a native vlan other than vlan 1 on a layer-3 interface on the palo alto.

Using VLAN 1 is NOT an option.
