I want to implement QoS in our network but I have a question. I've read that for non-ip traffic I have to perform the classification based on a configured Layer 2 MAC ACL. What does it mean? I need to mark the DSCP value in the access layer switches based on the destination IP and TCP port. Is this possible? or I have to mark the DSCP based on the MAC addresses?
Our access and distribution layers are 3750 switches, inter-vlan routing is performed in the distribution layer.
Thanks for the answer Giuseppe. But Is the traffic considered IP based in the access switches? The routing is performed in the distribution layer. I'm confused with the definition of "IP traffic" and "non-IP traffic" on the configuration guide. This guide say: "You can classify IP traffic by using IP standard or IP extended ACLs; you can classify non-IP traffic by using Layer 2 MAC ACLs."
