The interface configurations of firewall data ports
enable traffic to enter and exit the firewall. A Palo Alto Networks®
firewall can operate in multiple deployments simultaneously because
you can Configure Interfaces to support different
deployments. For example, you can configure the Ethernet interfaces
on a firewall for virtual wire, Layer 2, Layer 3, and tap mode.
The interfaces that the firewall supports are:
—The firewall supports two
types of media—copper and fiber optic—that can send and receive
traffic at different transmission rates. You can configure Ethernet
interfaces as the following types: tap, high availability (HA),
log card (interface and subinterface), decrypt mirror, virtual wire
(interface and subinterface), Layer 2 (interface and subinterface),
Layer 3 (interface and subinterface), and aggregate Ethernet. The
available interface types and transmission speeds vary by hardware model.
—These include virtual local area
network (VLAN) interfaces, loopback interfaces, tunnel interfaces,
and SD-WAN interfaces. You must set up the physical interface before
defining a VLAN, SD-WAN, or tunnel interface.
