ATM Overview
This chapter provides an overview of the Asynchronous Transfer Mode (ATM) features available
for the Enterasys X-Pedition. ATM is a cell switching technology used to establish multiple
connections over a physical link, and configure each connection with its own traffic parameters.
This provides more control over specific connections within a network.
Note: This release supports PVCs only. To learn more about PVCs, see Permanent Virtual
Circuits (PVCs) on page 496. Interfaces configured with PVCs do not support LSNAT
and VRRP.
The ATM line card provides an ATM interface, allowing integration of ATM with Ethernet and
other interfaces within a network topology supported by the XP. This chapter discusses the
following tasks:
• Creating a Virtual Channel (VC)
• Creating a Service Profile
• Applying a Service Profile
• Enabling Cell Scrambling
• Selecting the Cell Mapping Format
• Setting the Bit Allocation for the Virtual Path Identifier (VPI)
• Mapping a Peer Address to a VC
• Displaying ATM Statistics
