8 INTERFACE CONFIGURATION

OVERVIEW

	This chapter contains information on the following topics:
	■	Interface Configuration Overview
	■	Configure Interface
	■ Display and Debug Interface
Interface	The router interface refers to the part through which the router exchanges data
Configuration	and interacts with other devices in the network. It functions to implement data
Overview	exchange between the router and other network devices.
	The 3Com Router supports physical interface and logical interface on the router.
	Physical interface is an interface physically exists and can be supported by
	corresponding devices, such as the Ethernet interface and
	synchronous/asynchronous serial interface. There are two types of physical
	interfaces. One is the LAN interface, which mainly refers to the Ethernet interface
	through which the router can exchange data with the network devices in LAN.
	Second one is the WAN interface which includes interfaces like the
	synchronous/asynchronous serial interface, asynchronous serial interface, AUX
	interface, CE1/PRI, ISDN BRI interface. Through the WAN interface, the router can
	exchange data with the network devices in the external network.
	Logical interface is an interface that does not physically exist and needs to be
	established through configuration, which can also exchange the data. Logical
	interface includes the Dialer interface, sub-interface, standby center logic channel
	and virtual-template.

Configure Interface

Interface View To facilitate configuration and maintenance of the interface, the interface view has to be set in the 3Com Router software. Interface commands will be effective only when used in the view of relevant interfaces.

Enter the Interface View

With interface command in all views, you can enter the specified view of the interface.
