Shouldn't be=2000 ?
(AR - CIR) / 8
(64000 - 48000) / 8
You are using a 125ms time interval, and you can only burst in the first one. Also, be is in bits, not bps.

Subject: Traffic-shaping question
Hello all,
I have traffic-shaping question and i have also
mentioned the solution i used.
please help me out to identify if it's correct and
what commands are useful to determine that the traffic
shaping is going to work as configured.
Here is the question:
1.The router R5 has two PVC's going R1 and R13 each
has CIR of 48Kbps and burst size of 64Kbps.
2. The circuit from R5 to the frame-relay switch is
provisioned at a speed of 64Kbps.
3. If BECN's are recieved, R5 needs to throttle back
back the PVC's to 32Kbps.
4. Using CIR, Bc and Be configure traffic-shaping on
R5.
Now here is my config for Router R5 relevant to
Traffic-shaping. I have not shown any frame-maps or IP
information for clarity purposes.
!
interface s0
encap fram
no arp fram
no fram inv
frame-relay traffic-shaping
frame-relay class Shape
!
map-class frame-relay Shape
frame-relay cir 48000
frame-relay bc 6000
frame-relay be 16000
frame-relay mincir 32000
frame-relay adaptive-shaping becn
Now my question is do i need to configure R1 and R13
for shaping even if it is not mentioned in the
Question.
Also is my solution correct.
Thanks for your help.
