So I am looking for a few hours now after the right document from Cisco that explains properly what "Aggregate Throughput" is for their ISR routers.
For example I am interested in an 4451 router, which by default comes with 1 Gbps Aggregate Throughput.
This aggregate throughput is per interface (500 up 500 down) ? or per box and shared between all the interfaces ?
It's the aggregate of the traffic received ingress on all interfaces combined irrespective of the fact whether it's processed and sent out any other interface or punted to cpu and drops on the router cpu itself
