Example visualization of topology from multiple domains

Multiple domains held in one topology database

To enable topology visualization from multiple domains, each Network Manager domain forwards topology information to the Network Connectivity and Inventory Model (NCIM) topology database. When you have multiple domains, the topology from each domain is held in NCIM.

Linking discovered domains

You can find links between devices in different domains by configuring and running a cross-domain discovery.

The following figure shows an example of three discovery domains feeding data into a single NCIM topology database. All web clients connected to the Dashboard Application Services Hub can view topology maps in any of the domains by choosing a single domain from the domain menu.

If cross-domain discoveries have been run, an aggregated domain is created in the topology database, which includes device collections from all discovered domains. All web clients connected to the Dashboard Application Services Hub can view topology maps in all domains by choosing the AGGREGATION domain from the domain menu.
