I could not get u32 filter work with ingress qdisc. I tried the following commands to limit the incoming rate from 10.1.1.1 to 10kbit/s. tc qdisc add dev eth1 handle ffff:0 ingress tc filter add dev eth1 parent ffff:0 protocol ip prio 50 u32 match ip src 10.1.1.1 police rate 10kbit burst 10kbit mtu 1500 drop But looks like the filter is not matching any incoming packets from 10.1.1.1 tc -d -s filter is not showing any matched packets. I was able to get this work using iptables and fw filter with the following commands. iptables -A PREROUTING -t mangle -p tcp -s 10.1.1.1 -j MARK --set-mark 1 tc qdisc add dev eth1 handle ffff:0 ingress tc filter add dev eth1 parent ffff:0 protocol ip prio 50 handle 1 fw police rate 10kbit burst 10kbit mtu 1500 drop Is there any restriction that u32 filter cannot be attached to ingress qdisc? Or am i missing something in my configuration. Thanks Sridhar
