hiya folks
with regards to the above topic,
before i start, any comments are welcome, if i can improve my solution
here's a little custom queue example over frame for you to check out. maybe
it will help, hopefully anyway.
r6 is my frame hub, connected to r3 and r4 with multipoint, and r2 via p2p
in the below debug i snd traffic from r12 ro r1 and then from r4 to r1/r1 to
r4 simultaeneously,
topology
r1
| <---serial
r5
| <----ethernet
r7------------------sw
eth---> | | <---eth
r4------frp2m----r1

after applying that config, i sent traffic from r20 to r1, 1500byte packets
using icmp with debug custom on and part of the debug from r6 is listed below
6d23h: intf Serial0/0: dlci 110 PQ: (Pk size: 1504) Inc. Q # to 5
6d23h: intf Serial0/0: dlci 110 PQ: (Pk size: 1504) Inc. Q # to 5
6d23h: intf Serial0/0: dlci 110 PQ: (Pk size: 98) Q # was 5 now 4

6d23h: intf Serial0/0: dlci 110 PQ: (Pk size: 1504) Inc. Q # to 5
next, i pinged from r4 to r1 with extended ping 1000 packets and 1250 size,
while at the same time telnetting to r4 from r1, and then issuing commands
such as show run to get telnet traffic. below is a sample of the debug from
r6, the hub/transit router where the traffic shapping/ queuing was applied.

the frame pvcs look like this,,,
