Bandwidth Monitoring Question

Unanswered Question

Does anybody know what might cause a Network Monitoring Tool to report that a router interface is over 100% utilization? For instance our Solarwinds Orion Server reports that a FastEthernet connection provisioned for 50 Mbps (configured with a bandwidth 50000 statement) and is connected to an ATM Switch sometimes reports 150% utilization. Monitoring is being done via SNMP. The only time I've ever heard of this is for esoteric Frame Relay configurations with dynamic routing protocols that use bandwidth as a metric (say EIGRP for example.)

Any insight that anybody can offer would be appreciated.

I'm assuming that you have configured the bandwidth speed in NPM correctly. That being said it is a common problem in NPM. Search Thwack for over utilization and you'll see some posts on it.

Hope that helps.
