Protocol endpoints

A protocol endpoint describes a logical endpoint that can be used to gain access to some network service. Important protocol endpoints are IP, which represents the point at which an IP address (Layer 3) can be reached, and Media Access Control (MAC), which similarly represents the point at which a MAC (Layer 2) address can be reached.

A protocol endpoint is related to some lower-level network object by the LayeredOver relationship. Thus, an IP address would be LayeredOver an Interface.

Protocol endpoint classes instantiated by the IP Manager identifies the protocol endpoint classes that can be instantiated by the IP Manager.

Table 1. Protocol endpoint classes instantiated by the IP Manager

Class	Available to	Description
DLCI	All IP Manager products	A Frame Relay data link connection identifier endpoint.
IP	All IP Manager products	An IPv4 address endpoint.
DuplicateIP	All IP Manager products	Two or more occurrences of the same IPv4 address.
IPv6	All IP Manager products	An IPv6 address endpoint.
DuplicateIPv6	All IP Manager products	Two or more occurrences of the same IPv6 address.
IPRoute	All IP Manager products	The start of the Default Route that is assigned to a system.
MAC	All IP Manager products	A media access control endpoint.
STPNode	All IP Manager products	Spanning Tree Protocol capabilities for a switch port.
TCP	All IP Manager products	A Transmission Control Protocol listening endpoint, as is used by network services such as HTTP servers.
VirtualTCP	All IP Manager products	A virtual TCP listening endpoint that has a mapping between virtual to real TCP endpoints, as is used by load balancers to map URLs to real HTTP servers.
HSRPEndpoint	All IP Manager products	A Hot Standby Router Protocol endpoint, which is a logical element that is defined per interface per HSRP group on the hosting router.
VRRPEndpoint	All IP Manager products	A Virtual Router Redundancy Protocol endpoint, which is a logical element that is defined per interface per VRRP group on the hosting router.
