FTOS Behavior: For Option A above, when there is a conflict between the queue selected by
Dynamic Mode CoS (
Dynamic Mode CoS takes precedence. However, rate policing for the queue is determined by QoS
configuration. For example, the following access-port configuration maps all traffic to Queue 0:
However, if the following QoS configuration also exists on the interface, traffic is queued to Queue 0 but will be
rate policed at 40Mbps (qos-policy-input for queue 3) since class-map "a" of Queue 3 also matches the traffic.
This behavior is expected.

Likewise, in the configuration below, packets with dot1p priority 0 – 3 are marked as dot1p 7
