Hi, I''m trying to police the incoming traffic by using ingress qdisc,this is what I have in my script tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 4 \ handle 1: u32 divisor 1 tc filter add dev eth0 parent ffff: protocol ip prio 4 u32 \ match ip dport 4001 0xffff \ police rate 2000kbit burst 50k drop \ flowid 1:1 I''m sending a 9Mb traffic using iperf but noticed that the bandwith at the receiving end is 4 MB instead of 2M. When Im changing the police rate to 3MB, the traffic at the receiving end is 6MB. Any ideas why does this happen? Your help is greatly appreciated.

Hi Vinh, I''ve noticed the same thing some months ago and couldn''t figure out why. The workarround for this is to use half speed in your "upload" classes... It seens that it just happens to outgoing traffic (ingress or not). Maybe somone else can explian it... I just figured out the same problem...
