Explanation/Reference:

Three configurable interface types for a data-plane ethernet interface are Layer 3, VWire, and Layer 2. These interface types determine how the firewall processes traffic and applies security policies. Some of the characteristics of these interface types are:

Layer 3: A layer 3 interface allows the firewall to act as a router and participate in the network routing. The firewall can send and receive traffic from a layer 3 interface and apply security policies and inspect the traffic based on the source and destination IP addresses and zones of the interface1.

VWire: A virtual wire interface allows the firewall to transparently pass traffic between two network segments without modifying the packets or affecting the routing. The firewall can still apply security policies and inspect the traffic based on the source and destination zones of the virtual wire2.

Layer 2: A layer 2 interface allows the firewall to act as a switch and forward traffic based on MAC addresses. The firewall can send and receive traffic from a layer 2 interface and apply security policies and inspect the traffic based on the source and destination zones of the interface3.

Another reason to choose the Windows agent over the integrated PAN-OS agent is to save processing cycles on the firewall’s management plane.
