I have 3750s running IOS 12.2(40)SE as a L3 switch using EIGRP. I have two vlans with IP addresses assigned and everything is working great, except I notice that most of the traffic is processor switched. In the 3750 how do you get traffic to not be process switched?

However, I recommend against it. It will cause high CPU usage.
