[LARTC] use of 'BW'(bandwidth) parameter in CBQ

[LARTC] use of 'BW'(bandwidth) parameter in CBQ

[Amit Kucheria]

Hi all,

I tried setting the 'BW' parameter to 10Mbps for a 100Mbps link. Then i 
sent traffic as fast as I could and I got throughput of 95Mbps.

So i guess that parameter is not used for rate-limiting a flow. What is it 
used for?

Regards,
Amit

The bandwidth parameter is used for internal calculations and should be set 
to the NIC speed.  So 100Mbit for a 100mbit NIC.  If you want to limit the 
speed, you will have to add the bounded option and set the rate to the speed 
you want to limit the traffic.
