Campus LAN QoS Considerations
For the access layer of the campus LAN, you can classify and mark frames or packets to apply quality of service (QoS) policies in the distribution or at the enterprise edge. Classification is a fundamental building block of QoS and involves recognizing and distinguishing between different traffic streams.
