ATM Network Map You can examine the overall structure of the ATM Network and the connectivity of edge devices. In particular, you can examine the following items:

■ATM Switch topology at Network-to-Network Interface (NNI) level

■Connectivity Between ATM Switch Domains at NNI level

■Edge Device connectivity at User-Network Interface (UNI) level

■Virtual Channels across NNI and UNI Interfaces.

■List the ATM address space of the Network

The ATM Network Map displays the most up to date physical connectivity of the network. If a link between two switches fails, the map deletes the link from the ATM Network Map instead of displaying the link in the critical (red) state.

To detect unexpected changes in the network configuration, you can maintain snapshots of windows of interest. These snapshots may be used as a baseline for comparison, for example, of detecting a link fault. Link faults can cause a link icon to disappear from a window.

The snapshot facility is located in the Map menu of HPOV.
