I've recently setup our PAN-2020's with L3 sub-interfaces presenting VLANS to our core switches (per this discussion: ). However, I've run into a problem that I can't manage or connect to devices, like our SAN, KVM, and even the PAN Firewall (management port) because they are on the same switch and use the default vlan of the switch. If I define an available L3 port as a management network, and leave it untagged, it creates headaches and breaks the L3 vlanning.
My question is, can I create a L3 interface with a network and untagged, attach it to another VR and route management traffic to that VR, and then present that interface to the switch with the untagged network. I don't think that should cause any issues, but wondered if anyone's had experience with this, or ran into similar issues? I've also found this discussion, but they've not complete given me any insight into if this is possible or not:
