This chapter describes the level of support that Cisco ANA provides for the base logical components, as follows:

•Inventory and Information Model Objects (IMOs)

•Service Alarms

Inventory and Information Model Objects (IMOs)

This section includes the following tables:

•Managed Element (IManagedElement)

•Logical Root (ILogicalRoot)

•Physical Root (IPhysicalRoot)

•Managed IP (IManagedIP)

•Context (IContext)

•System Service (ISystemService)

Managed Element

The following Managed Element object describes the root object of a network element, from which all it physical (chassis, slots, modules, port connectors) and logical (routing and switching entities, communication and physical termination point) components' objects are being accessed.
