| Abstract: | The Remote network-MONitoring (RMON) standard isa valuable addition to the Simple Network ManagementProtocol (SNMP), providing network managers withimportant global network information. Unlike SNMPagents, RMON agents operate in promiscuous mode andprocess all packets traversing the local net. The RMONmanagement information base (MIB) supplements the SNMPMIB-II standard MIB. We present common network problems that cannot be solved using existing MIB-II orRMON objects. To solve these problems, we developextensions to the RMON matrix group to gather networklayer statistics that result in a view of packet traffic beyond the local network. Our extensionsincrease the ability to analyze and solve networkconfiguration problems and perform troubleshooting. Wedemonstrate our results by implementing and analyzingtwo  live internetworking problems. Datacollected from these experiments showed that networktraffic patterns can be isolated by individual subnets,thus more easily identifying sources ofcongestion. |
