The Global Console presents the topology information in a variety of dynamically updated formats that show the status of the IS-IS and physical-transport objects and their many relationships. One of those formats is the topology map, which is a graphical representation of the topology.

Viewing topology maps is an easy and quick way to learn more about the source, impact, and cause of IS-IS notifications. You view the IS-IS topology maps, such as the one shown in IS-IS topology map, by using the Map Console view of the Global Console.
