My boss wants to make sure that class of service is working.

I am curious about the best way to monitor (1) that tags are happening as desired and (2) that traffic is prioritizing per the tags.  Any ideas?

    Did you mean Quality of Service?

    Class of service
    From Wikipedia, the free encyclopedia

    Class of Service (CoS) is a 3 bit field within a layer two Ethernet frame header when using IEEE 802.1Q. It specifies a priority value of between 0 (signifying best-effort) and 7 (signifying priority real-time data) that can be used by Quality of Service disciplines to differentiate traffic.

    Class of Service (CoS) is a way of managing traffic in a network by grouping similar types of traffic (for example, e-mail, streaming video, voice, large document file transfer) together and treating each type as a class with its own level of service priority. Unlike Quality of Service (QoS) traffic management, Class of Service technologies do not guarantee a level of service in terms of bandwidth and delivery time; they offer a "best-effort." On the other hand, CoS technology is simpler to manage and more scalable as a network grows in structure and traffic volume. One can think of CoS as "coarsely-grained" traffic control and QoS as "finely-grained" traffic control.

    OK - thanks for that - not used that term before.
