ingress can be used to control the incoming packet, such as: tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.11 police rate 10kbit burst 10k drop flowid :1 tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.22 police rate 10kbit burst 10k drop flowid :2 first ,I do not sure these method can use class(could it do? I tested it can not do). if it can do it ,please give me a example. second, rate can not be shared, if i want to control the incoming packet rate not throug egress qdisc, and the rate can be shared, please tell me how can i do. _________________________________________________________ Do You Yahoo!? 摊开你的掌心 让我看看你 http://sweepstakes.yahoo.com/2002cnuser
