ATM Configuration
Configuring Permanent Virtual Circuits (PVCs); adding and deleting connection entries
The ATM interface available via the 7A06-01 NIM module provides the
connectivity that allows you to merge ATM network segments with traditional
LAN technologies via the SmartSwitch chassis backplane. Current versions of
7A06-01 firmware use 802.3 VC-based multiplexing for bridging protocols to
move PVC traffic between the ATM front panel connection and the SmartSwitch
backplane; future versions will add support for ATM Forum LAN Emulation and
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 AToM MIB
window provides the means for accomplishing these configurations.
Accessing the AToM MIB Window
To access the AToM MIB window
from the Hub View:

display the Module Menu (remember, this menu is the same for all application
display modes).
2. Drag down to ATM, and release.
