The Topology section provides information on specific classes, attributes, relationships, and events related to the topology objects created to represent Cisco ACI.

Cisco ACI version 4.1 is supported in VMware Telco Cloud Operations.

For more information on getting the topology data, see the #GUID-54DB1EFA-0E78-4154-A665-4988E8CA8C29.

The following logical entities are created on the top of existing physical fabric:
