[LARTC] cbq bounded problem

[-- Attachment #1.1: Type: text/plain, Size: 570 bytes --]

Dear all,

I have 1 mbps line to internet.

Our linux server is connected to router of 1mb

Linux server gets 1mb bandwidth.

I have done SOURCE MASQUERADING on linux.

I have attached a cbq bandwidth script. I want to allow the traffic to restrict to 200Kbps. it should not exceed beyond 200. 

I have made a configuration and i kept on the server but the traffic goes beyond 200 .....it even goes to 350 and 400.
how can i restrict the traffic on 200. ????
plz check the attached script .
plz open in word.
any help is great for me. 

Thanks,
Joel

Some tips :
- Adding the sfq qdisc to class 10:200 is useless.  It's removed as soon as 
you add a subclass.
- Are you sure your packes are queued in the class you want?  Check it out 
with tc -s -d class show dev eth4.
- prio 100 is too much.  The maximum is 7.
- avpkt 800 should reflect your average packet size.  Are you sure it's only 
800 bytes?
- Is your NIC configured at 10Mbit?  (bandwidth parameter)
Take weight = rate / 10.
- Use htb and visit www.docum.org :)

[-- Attachment #1: Type: text/plain, Size: 378 bytes --]

Dear friends,

I have 1 mbps line connected to linux server.

from linux server i have masqueraded some clients. I want to use only 200
kbps. I have attached the script.
But on this script the traffic goes up to 350 kbps.
how can i bound the bandwidth to 200 kbps.
it should not exceed more than that.
plz see the script.
where m i wrong.
any suggestions???

Thanking You,
Joel
