Explanation

A Subinterface (Layer 3 logical interface) is configured with a specific 802.1Q VLAN tag and only accepts frames carrying that exact VLAN ID. This allows a single physical interface to serve multiple VLANs, each as a separate logical interface with its own IP address and zone. A Trunk Interface (Layer 2) can carry multiple VLANs but does not itself map to a single specific VLAN ID the way a subinterface does. Access Interface is a Layer 2 mode for untagged traffic. 'Tab Mode' is not a PAN-OS interface type.
