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:
1. Click either mouse button on any Module Index or Module Type text box to
display the Module Menu (remember, this menu is the same for all application
display modes).
2. Drag down to ATM, and release.
