Network Topology

The Cisco Discovery Protocol (CDP), although a proprietary one, plays a major role in discovery of all Cisco's network equipment. Hence it is used as part of the physical topology discovery of Cisco's equipment by searching for the existence of local CDP neighbors signature, gathered from the physical layer, in any remote side's port of the same type.

Service Alarms

The following alarms are supported for this technology:

•Cloud Problem

•Discard Input Packets/Normal Discard Input Packets

•Dropped Output Packets/Normal Dropped Output Packets

•Link Down/Link Up

•Port Down/Port Up

•Receive Utilization/Receive Utilization Normal
