At the end of a topology split and assuming that the IsTopoSyncEnabled and EnableAutoEdgeManagement configuration parameters are both TRUE, the Topology Split Manager performs the following tasks:
Identifies which network adapters (ports or interfaces) on a proxy device do not have a connection that is fully monitored by the domain.
Directs the domain’s IP Availability Manager to unmanage those network adapters during a subsequent pending discovery.
Edge management reduces management overhead by unmanaging network adapters that attach to incomplete connections.
As an aid to understanding the discussions that follow, Data model representations of network adapters and their connections”Examples is presented to show how network adapters and their connections are represented by the Topology Split Manager and the IP Availability Manager.
Not all relationships are shown in the figure. For example, neither the HostedBy relationship from an IP object to its host device nor the LayeredOver relationship from an IP object to its MAC is shown.
