Cisco Switching/Routing :: Nexus 7010N7K-M132XP-12 Queuing

NX-OS 5.0(3)N2(1)Nexus 7010N7K-M132XP-12 line cards.By default the linecards/system use only 2 egress queues for the 32 port M1 cards.
 
1p7q4t-out-pq1  (matches cos 5-7)1p7q4t-out-q-default  (matches cos 0-4)Which really doesn't line up with what wanted so we modify the config on the default vdc to the following.
class-map type queuing match-any 1p7q4t-out-pq1
match cos 5
class-map type queuing match-any 1p7q4t-out-q2
match cos 7
class-map type queuing match-any 1p7q4t-out-q3
[Code]....

By modifying the default queues it's affected the default egress  policy-map, and in order to function correctly, a custom default list  needs to be setup. With the default egress policy, anything not in the above 4 queues gets dropped.
 
Why doesn't the output queue in the default policy map (out-q3) match the actual class-map name of 1p7q4t-out-q3Are my assumptions about the output discards correct relating to the fact there is no relevant mapping for the modified egress queues in the default system policyWhere in the config guide is this? I've seen some reference that infer it, but don't actually point it out. Why this is a system wide config item, rather than on a per vdc basis.
