A device connection is a link between two network adapters. IP Availability Manager performs connectivity analysis on the following device connection object types:
Cable — A connection between a port and an interface. For example, a cable connects a port on a switch to an interface on a router.
TrunkCable — A connection between two ports. Switches are often trunked to connect multiple segments or to provide redundant pathways through the network.
NetworkConnection — A connection between two interfaces. A network connection can be a logical connection or a physical connection. An example of a logical connection is when routers are connected through a virtual circuit and none of the intermediate network devices are included in the topology. An example of a physical connection is when routers are connected through a serial or point-to-point connection.
