LARTC - Oct 2002 - (no subject)

I am trying to limit the rate for all traffic on the incoming interface of a
Linux bridge. So far I have only been able to limit the outgoing rate. I am
assuming I will have to use an ingress qdisc. The example found on the
documentation works without errors but I can''t see any rate reduction
(maybe
because it applies to SYN''s only). Does anybody know if limiting rate
on the
incoming interface is possible on a Linux bridge, and if so, how to go about
configuring it.

Thanks.

If you shape on a bridge, why not shaping on both interfaces ?  That way you 
can shape in both directions.
And you can use the ingress qdisc, but the shaping acutally happens with the 
policers in combination with the filters.  Policsers are a sort of tbf, you 
can specify a maximum rate to it.  So the filters will only match packets at 
a certain rate and you can drop packets exceeding that rate.  So you can 
limit incoming packets.
