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.
