[c-nsp] simple bandwidth throttle recepies?

[Mike]

Hello,

    From time to time on my network, I need to connect customer 
equipment directly to the switches on my backbone where I don't have any 
effective network controls for bandwidth useage and so forth. To be 
sure, these cases are really limited, but each time it does occur it 
exposes us to one more potential point where a subscriber/network user 
can get far more than their 'fair share' and I can't do anything 
effective about it. I have 2924xl's that have been in service a long 
time but they have no bandwidth limiting/qos features, and what I was 
thinking was if maybe we refreshed these sites with newer generation 
cisco switches that do have this feature. I don't want to play games 
however - the qos feature would need to be able to limit incomming and 
outgoing traffic at the switchport, and do it for all ethernet protocols 
and not just by ip protocol fields (example, I have some on pppoe).

    I don't care to try and do any traffic classification, I really just 
want to say that port fa0/15 should have 2mbps up/down and that's it. 
Even better would be limiting the rates asymmetrical and in less than 
1mbps increments but I don't know what's available. I do want 'cheap' 
however and anything on the refurb market/ebay and with copper 
10/100mbps ports that can do this would be preferable. So I guess I am 
looking for both a specfic hardware reccomendation as well as a sample 
qos receipe that would demonstrate to acheive this on said hardware.

Thank you. (No vendors please).
