ATM Configuration
Viewing connection data; configuring Permanent Virtual Circuits (PVCs); adding and deleting
connection entries
The ATM interface provided by the HSIM-A6DP module provides the connectivity that
allows you to merge ATM network segments with traditional LAN technologies via the
SmartSwitch 6000 or Matrix E7 chassis backplane. Current versions of HSIM-A6DP
firmware use 802.3 VC-based multiplexing for bridging protocols to move PVC traffic
between the ATM front panel connection and the switching backplane; future versions
will add support for ATM Forum LAN Emulation and Enterasys’ 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.

Accessing the ATM Connections Window

To access the ATM Connections window from the Device View:
1. Click on Device on the Device View menu bar to access the Device menu.
2. Select ATM Connections. The Current ATM Connections window,
Figure 7-1, will appear.
TIP
Note that the ATM Connections option will only be available if at least one HSIM-A6DP
is installed in the module.
