Table 59-1 on page 59-2 describes the types of interfaces that can be configured on Cisco IOS routers.
Table 59-1 Router Interface Types
Type Description
Null Null interface.
Analysis-module A Fast Ethernet interface that connects to the internal interface on the
Network Analysis Module (NAM).
Note You cannot configure parameters such as speed and duplex
mode for this type of interface.
Async Port line used as an asynchronous interface.
ATM ATM interface.
BRI ISDN BRI interface. This interface configuration propagates to each B
channel. B channels cannot be configured individually.
Note You must configure a dialer interface policy for calls to be
placed on a BRI interface. For more information, see Dialer
Interfaces on Cisco IOS Routers, page 59-27.
BVI Bridge-group virtual interface. BVI interfaces are used to route traffic
at Layer 3 to the interfaces in a bridge group.
Content-engine Content engine (CE) network module interface.
Note You cannot configure parameters such as speed and duplex
mode for this type of interface. You cannot create subinterfaces
for this type of interface.
Dialer Dialer interface.
Ethernet Ethernet IEEE 802.3 interface.
Fast Ethernet 100-Mbps Ethernet interface.
FDDI Fiber Distributed Data Interface.
Gigabit Ethernet 1000-Mbps Ethernet interface.
Group-Async Master asynchronous interface. This interface type creates a single
asynchronous interfaces to which other interfaces are associated. This
one-to-many configuration enables you to configure all associated
member interfaces by configuring the master interface.
HSSI High-Speed Serial Interface.
