Configuring ATM Interfaces

Asynchronous Transfer Mode (ATM) is a network protocol designed to facilitate the simultaneous handling of various types of traffic streams (voice, data, video) at very high speeds over the same physical connection. ATM relies on the concepts of virtual paths and virtual circuits. A virtual path, represented by a specific virtual path identifier (VPI), establishes a route between two devices in a network. Each VPI can contain multiple virtual circuits, each represented by a virtual circuit identifier (VCI).

For ATM physical interfaces, you can configure two ATM-specific physical device properties: the maximum number of virtual circuits (VCs) allowed on a virtual path (VP) and communication with directly attached ATM ...
