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.
TIP
Note that the ATM Connections option will only be available if at least one 7A06 module
is installed in the chassis.
