Errrm Carl,

you say you have read the SRND for QoS - specifically the Campus QoS Design?

You ask "it says that QOS policies should be applied at the distribution layer,"

On page 1 of the Campus QoS Design under "QoS Design Overview" just above figure 2-2 a thrid of the way down the page - there is a big chunk of text, I will post for you:-

"So where is QoS required in campus?

Access switches require the following QoS policies:

•Appropriate (endpoint-dependant) trust policies, and/or classification and marking policies

•Policing and markdown policies

•Queuing policies.

Distribution and core switches require the following QoS policies:

•DSCP trust policies

•Queuing policies

•Optional per-user microflow policing policies (only on supported platforms)"

Did you miss this when you read the document?
