ATM Conﬁguration

Viewing connection data; conﬁguring Permanent Virtual Circuits (PVCs); adding and deleting connection entries

The ATM interfaces provided by the 9A128-01 module provides the connectivity that allows you to merge ATM network segments with traditional LAN technologies via the FDDI FNB backplane. Current versions of 9A128-01 ﬁrmware use 802.3 VC-based multiplexing for bridging protocols to move PVC trafﬁc between the ATM front panel connection and the switching backplane, and support ATM Forum LAN Emulation; future versions will add support for 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 Current ATM Connections window provides the means for accomplishing these conﬁgurations.

NOTE

For current ﬁrmware versions available for the 9A128-01, you can only view current connections; you will not be allowed to add new connections or modify existing connections.

Accessing the ATM Connections Window

To access the ATM Connections window from the Module View:

1.Click on Device on the Module View menu bar to access the Device menu.

2.Drag down to ATM Connections..., and release. The Current ATM Connections window, Figure 3-1, will appear.
