Can someone please help resolve a disagreement here. We have a Cisco CAT 5509 with several VLans set up. All of the ENet ports are 10/100 along with several fiber Giga ports.
Out network performance monitor (Solarwinds) is showing that quite frequently we are well in excess of 100% utilization (as high as 400%). My network analyst says that is because that even though the ports are 10/100, the actual routing supervisor can't handle more than 10 Meg and the traffic is queued up.
I have trouble buying it. Why would Cisco have a switch with boards capable of running at 10/100/1000, but a supervisor unable to route the VLans at more than 10 Meg. Secondly, perhaps I'm just being too logical, but how can you get more than 100% utilization? It seems like either the tool (Solarwinds) is reporting incorrectly ... or the speed we are saying the port is running at (10 Meg) is incorrect. If the speed is actually running at 100 Meg, then the performance of 40% is more understandable.
