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 in advance
