Rate Limit problem

Hello,

the goal is to provide my customers bandwidth 128kbps shared by two.

so for that i have applied a CAR rate limit to an ATM subinterface under which i have configured multiple PVCs to terminate PPPoE Tunnels .

but it seems , and referring to outputs of " sho inter rate-limit" that the rate limit is not working.

the Cisco device used is 7206 VXR ( NPE 400) and IOS used is:

c7200-jo3s-mz.122-4.b5.bin.

Here are the Interface config and the ouptuts od sho inter rate:

interface ATM4/0.11 multipoint

rate-limit input 720000 90112 90112 conform-action transmit exceed-action drop

rate-limit output 720000 90112 90112 conform-action transmit exceed-action drop

pvc name_dsl 3/xxx

ATM4/0.11 DSL-128:2

Input

matches: all traffic

params: 720000 bps, 90112 limit, 90112 extended limit

conformed 0 packets, 0 bytes; action: transmit

exceeded 0 packets, 0 bytes; action: drop

last packet: 65584036ms ago, current burst: 0 bytes

last cleared 18:12:56 ago, conformed 0 bps, exceeded 0 bps

Output

matches: all traffic

params: 720000 bps, 90112 limit, 90112 extended limit

conformed 0 packets, 0 bytes; action: transmit

exceeded 0 packets, 0 bytes; action: drop

last packet: 65584036ms ago, current burst: 0 bytes

last cleared 18:12:56 ago, conformed 0 bps, exceeded 0 bps.

any insight on this ? this is critical to me because i am using rate limit in order to allocate bandwidth to my DSL users .

anothe question :Is there another scientifical and accurate way to share bandwidth in the order 128:2.

i hope that i was clear in my description and sorry fot this long story.

Thanks and Best Regards,

Ali

Re: Rate Limit problem

I guess this has got something to do with a standard bug on this image, not sure though...
