Re: c4506 cef

The Catalyst 4500 series switches, which includes the Catalyst 4948 switches, has a sophisticated packet-handling methodology for CPU-bound traffic. A commonly perceived problem is high CPU utilization on these switches. The following document provides details about the CPU packet-handling architecture and shows you how to identify the causes of high CPU utilization on these switches.
