Topology

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

Cisco ACI version 4.1 is supported.

Following Logical entities are created on the top of existing physical fabric:

Class	Key Attributes	Key relationship	Problem and Event
ControlCluster	IsAnyComponentDown IsClusterDown IsEveryComponentDown NumberOfComponent NumberOfFaultyComponents	ComposedOf Manages ProvidesClientServiceTo	AllComponentsDown AtRisk Down ReducedRedundancy
ControllerNode	Status IsControllerDown	HostedBy PartOf	Down
Tenant	NumberOfEPGs	ClientServiceProvidedBy Owns	None
BridgeDomain	Name	Associates	None
EndPointGroup	Name	AssociatedWith ComposedOf OwnedBy Uses	None
Contracts	Name	UsedBy	None

Refer VMware Smart Assurance IP Domain Manager User Guide for existing physical fabric.

The table Support of Cisco ACI Components in IP describes the components which are discovered as a part of Cisco ACI

Note: Kafka_Service object is created to support fail-over as a part of discovery, for internal purposes. The fields, DiscoveryTopic and Monitoring Topic are empty and must not be populated as they have no effect on either discovery or monitoring of Cisco ACI fabric.
