Hello, we have a Cisco WS-C3750G-24T running IOS 12.2(25)SEE (image C3750-IPSERVICESK9-M). We have this device running layer-3 services for a few hosts, and total throughput is probably around 300Mbps peak for the whole network. The setup is very simple, and this device is one of two devices on the network that is running OSPF. The other is our border router, which also runs BGP.
We are seeing very unusual CPU usage on this 3750G. I have attached a graph from our monitoring platform, and I have verified that the values are correct here.
How can I track down what is causing this unusually high load?
