Actualy the `rate' option is what control bandwith. AFAIK `bandwidth'
represents the `real' bandwidth of the device. So in this example you must use:
tc class add dev eth0 parent 2:0 classid 2:1 cbq bandwidth 10Mbit \
rate 2Mbit avpkt 1000 prio 1 allot 1514 weight 1 maxburst 10 \
bounded isolated
This will set output bandwidth on eth0 to 2Mbit, but will also must to set some
kind of filter to join packets to the class 2:1. For example:
tc filter add dev eth0 parent 2:0 protocol ip prio 1 u32 \
match ip dst 1.1.1.0/24 flowid 2:1
Where the dst parameter should be the net connected to your eth0 (i.e. replace
`1.1.1.0/24' with the real one) or even small part of it. I suggest you to

Hope this helps ;-)
