I had Cisco tac help me create some policies for qos for our voice traffic on our nexus 9k at the datacenter.  I think i understand what he did but am still a little cloudy.  hoping someone can clear up.    

We have 2 policy-maps, one with type queuing and one type qos  to classify and put in the priority queue.   Both of these policy maps have the same name.  

policy-map type queuing voice
policy-map type qos voice

Are these the same policy-maps with different types or 2 totally separate policy-maps where i could have used different names?

policy-map type queuing voice
This one adjust queue size per priority category (how many packets can be in specific queue).
policy-map type qos voice
This one is adding specific types of traffic (defined in class-maps by  some criteria (cos markings dscp marking, access list etc)) into priority categories and specify behavior for each priority class (treatment for specific class - max bandwidth, drop rate etc).
Those are two different types of policy-maps.
Those two can have different names, check policies under # system qos, most likely you will see
# system qos
# service-policy type queuing output voice
# service-policy type qos output voice
at least that's how it can be configured on 5k devices (not sure for 9k, but I guess it is similar).

so they can have different names or the same names but they are basically different policy-maps since they are different types if i understand it?
