Configures
Allows configuration of a given interface
Default
None
Description
This command enters the interface configuration mode for the given interface
and subinterface
. The interface most commonly consists of an interface type followed by the number of the particular interface (for example, ethernet0
). A space is allowed (and commonly used) between the interface type and the number. Table 17-10 shows the most common interface types. On more complex routers, the interface number can be specified in a number of different ways: as a slot/port
combination, as a slot/adapter/port
combination, or as a slot/port:channel-group
combination. The appropriate form depends on the hardware you’re dealing with. The interface specification can include a subinterface number; subinterfaces are most common when using protocols like Frame Relay or ATM, which can package a number of communications channels on a single physical connection. The point-to-point
keyword indicates that a subinterface is logically connected to a single remote node; multipoint
indicates that it is logically connected to a number of remote nodes. multipoint
and point-to-point
are most commonly used on Frame Relay and ATM interfaces.
