Unitary computer systems

A unitary computer system, or just system, represents a computer-based network entity. Important classes of the computer system include Host and the following relay systems: Hub, Bridge, Switch, and Router. The relay systems forward packets at Layer 1 (a Hub), Layer 2 (a Bridge or Switch), or Layer 3 (a Router) in a network.

Unitary computer system classes instantiated by the IP Manager identifies the unitary computer system classes that can be instantiated by the IP Manager.

Table 1. Unitary computer system classes instantiated by the IP Manager

Class	Available to	Description
Bridge	All IP Manager products	A protocol-independent system that passes packets at the data-link layer between physically separate LANs.
Host	All IP Manager products	A general purpose computer, such as a workstation or a server.
CallServer	All IP Manager products	A system that hosts an application server that manages the setup or connection of telephone calls, such as a system that hosts the Call Manager application for a VoIP network.
FileServer	All IP Manager products	A system that hosts file shares, such as a Data Mover component of a Celerra NAS gateway.
Hub	All IP Manager products	A system that connects multiple physical segments. A hub repeats signals that are received on any of its ports to all of its other ports.
Node	All IP Manager products	A system that has an unrecognized objectID. The IP Manager probes a Node for standard MIB-II data to monitor and analyze a Node object.
Probe	All IP Manager products	A system that monitors networks or other systems. An example is a remote monitoring (RMON) probe.
Router	All IP Manager products	A system or, in some cases, software in a computer that determines the next network point to which a packet should be forwarded as it travels towards its destination. A router might also be a virtual router, which is a software emulation of a router that is implemented within a physical router or switch.
Firewall	All IP Manager products	A system that controls the flow of traffic between networks.
LoadBalancer	All IP Manager products	A system that distributes client traffic across multiple web servers.
MSFC	All IP Manager products	A multilayer switch feature card in a Catalyst 6000/6500 switch that runs Cisco IOS router software and performs routing between virtual LANs (VLANs).
RSFC	All IP Manager products	A route switch feature card in a Catalyst 5000/5500 switch that runs Cisco IOS router software and performs routing between VLANs.
RSM	All IP Manager products	A route switch module (Card) in a Catalyst 5000 switch that runs Cisco IOS router software and performs routing between VLANs.
Switch	All IP Manager products	A system that switches packets, typically at wire speeds, between physically separate network segments.
MediaGateway	All IP Manager products	A system that hosts an application server that converts one media stream to another, such as a system that hosts the media server and gateway applications for a VoIP network.
TerminalServer	All IP Manager products	A specialized system that connects terminals to a network.
Uncertified	All IP Manager products	An uncertified object that identifies a system that has yet to be certified by VMware, Inc.. The IP Manager does not monitor Uncertified objects.
