Cabletron Systems 7000 manual ATM Configuration, Accessing the ATM Connections Window

Chapter 6

ATM Configuration

Viewing connection data; configuring Permanent Virtual Circuits (PVCs); adding and deleting connection entries

The ATM interface provided by the 7A06-01 NIM module provides the connectivity that allows you to merge ATM network segments with traditional LAN technologies via the SmartSwitch 7000 chassis backplane. Current versions of 9A128-01 Þrmware use 802.3 VC-based multiplexing for bridging protocols to move PVC trafÞc between the ATM front panel connection and the switching backplane; future versions will add support for ATM Forum LAN Emulation and CabletronÕs SecureFast Switching.

An ATM network uses two types of virtual channels, or circuits: Switched Virtual Circuits, or SVCs, and Permanent Virtual Circuits, or PVCs. SVCs are created and dismantled dynamically on an as-needed basis, and require no management deÞnition; PVCs, however, must be manually conÞgured. The Current ATM Connections window provides the means for accomplishing these conÞgurations.

Accessing the ATM Connections Window

To access the ATM Connections window from the Chassis View:

1.Click on Device on the Chassis View menu bar to access the Device menu.

2.Drag down to ATM Connections, and release. The Current ATM Connections window, Figure 6-1, will appear.

Note that the ATM Connections option will only be available if at least one 7A06 module

TIP is installed in the chassis.
