RE: QOS in Cisco 7609

Terry,

 From what i can see in the config you have provided, L3 QoS policy
thats defined is used for Rate limiting input and output traffic,
Where as the L2 CoS policy is used to assign incoming packets to
appropriate ingress Queue. (Along with some Drop threshold defined for
the queues).

IN summary L3 markings are used for for Rate limiting
L2 markings are used for queuing.

HTH,
