I have a generic question about the Palo alto way of treating sub interfaces? Can I do sub interface on one of the physical interface for one netwrok address? for example, I did sub interface the ethernet1/5 as ethernet 1/5.123 and configured the netwrok 10.11.12.13/24 and no other networks exist on overall that physical interface. Connection to downstream switch is trunk by the way with allowing native vlan and vlan 123?
I believe we can do this, as I couldn't recall exactly what I did preaviuosly, but I did ran into issues with Cisco ASA firewall,
when I ran a trunk from switch to ASA and allowing only native and one custom vlan, ASA didn't accept the packets coming from the custom vlan when I did subinterface for that one vlan.
You dont need to use native vlans for the PAN. What I do is setup sub-interfaces as L2 and then make the vlan interface L3. Just seems more flexible to me but its just my opinion.
Yes you can set it up as you describe. Physical interface can be blank.
