Overview

The router interface refers to the part through which the router exchanges data
and interacts with other devices in the network. It functions to implement data
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.
Tabl e 80 Enter view of specified interface
Operation Command
