Which is your problem? a) network packet can't be classified into the class which is set to net_cls.classid b) network packet can be classified into the class which is set to net_cls.classid, but its bandwidth limit doesn't work correctly. If your problem is b), unfortunately I can't help you. Because I am a begginer of cls_cgroup, and I haven't tested enough. (But I think I might be facing same problem.) If your problem is a), you should check 'tc -s filter show'. You can see the result of classifing by cls_cgroup. I can classified to the class which is set to root's net_cls.classid. Environment: kernel: 2.6.30 tc: iproute2-2.6.29-1 with tc/f_cgroup.c patch in latest git.
