priority queueing on a 3750

Well, according to these show commands it doesn't appear to be working. Lots of traffic has passed over this link destined for the ip in question, but, no acl hits or queue stats that show what I'd expect.

Yet according to these show commands the low priority isn't even being used, the high queue is, and on the interface itself none of them are. Something's not right.
