Ok, so now I re-did the map class, and as you can see when the capabilities
are exceeded the priority queueing kicks in (pings fail but that is just a
side effect of the ridiculous map class), just like you said, thank you for
clearing that up. So now my question is, if you have an interface, and you
want to apply frame relay traffic shaping and priority queueing which is
active at all times, can it be done? I don't think so, but it doesn't hurt
to ask....
map-class frame-relay tor5
frame-relay cir 1500
frame-relay bc 300
frame-relay be in 56000
frame-relay be out 1000
frame-relay mincir 1000
frame-relay adaptive-shaping becn
frame-relay priority-group 1
!
priority-list 1 protocol ip high
r3#ping 10.1.11.14
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.11.14, timeout is 2 seconds:
4d04h: PQ: Serial0 dlci 201 : ip -> high.
4d04h: PQ: Serial0 dlci 201 : ip -> high.
4d04h: PQ: Serial0 dlci 201 : ip -> high.
4d04h: PQ: Serial0 dlci 201 : ip -> high.
4d04h: PQ: Serial0 dlci 201 : ip -> high.
Success rate is 0 percent (0/5)

Guy,
Queuing will only happen if the traffic being sent out of the Interface or
PVC exceeds the bandwidth capability of the link or CIR of the PVC.
You might try using an extended ping so you can adjust the byte size
of the ping packets. Also, I would lower the cir value in your map-class.
Someone else feel free to jump in here.
