ATM Configuration

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

The ATM Connections option will be available when you have an ATM BRIM installed and enabled in your device. The ATM interfaces provided by an ATM BRIM provide the connectivity that allows you to merge ATM network segments with traditional LAN technologies.

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 open the ATM Connections window:

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

2.Click on ATM Connections. The Current ATM Connections window, Figure 5-1, will appear.
