Answered Question
Dec 11th, 2008

Frame Relay rate limiting :

·Maximum throughput is 128kbps

·During congestion, your provider will mark any traffic in excess of 48kbps as discard eligible,

Make sure your throughput changes accordingly, based upon BECNsreceived, only.

·Your token bucket interval is 125 ms

Config :

map-class frame-relay CIR

frame-relay adaptive-shaping becn

frame-relay cir 128000

frame-relay bc 16000

frame-relay mincir 48000

interface serial 0/0

frame-relay class CIR

frame-relay traffic-shaping

All the gurus, do you think mine config is correct according to the requirement ? Thanks

Looks good. I copied and pasted your config in a router and here is the PVC output.

Shaping adapts to BECN

pvc create time 1d18h, last time pvc status changed 1d18h

cir 128000 bc 16000 be 0 byte limit 2000 interval 125

mincir 48000 byte increment 2000 Adaptive Shaping BECN

HTH,
