Physical Interfaces
—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.
