When I check the difference between WS-X6816-GBIC and WS-X6416-GBIC, I noticed that the mian diffrence is dCEF,What is it and where can I find the related document in cisco web site?
dCEF is distributed Cisco Express Forwarding. Normal CEF is where the supervisor engine holds the forwarding table and the adjacency/neighbour table and makes forwarding decisions for every line card. The main difference with dCEF is that each line card holds a copy of the neighbour table and forwarding table and can make forwarding decisions for itself. This takes burden of the Supervisor engine and speeds up packet forwarding
