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

The ATM interfaces provided by the 9A128-01 module provides the connectivity 
that allows you to merge ATM network segments with traditional LAN 
technologies via the FDDI FNB backplane. Current versions of 9A128-01 firmware 
use 802.3 VC-based multiplexing for bridging protocols to move PVC traffic 
between the ATM front panel connection and the switching backplane, and 
support ATM Forum LAN Emulation; future versions will add support for 
Cabletron’s 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 
definition; PVCs, however, must be manually configured. The Current ATM 
Connections window provides the means for accomplishing these configurations.

To access the ATM Connections window from the Module View:

1.

Click on Device on the Module View menu bar to access the Device menu.

2.

Drag down to ATM Connections..., and release. The Current ATM 
Connections window, 

, will appear.
