"I don't know where you're getting your tc, because the current iproute2 does not have "protocol arp".

Whenever I try things with tc and fail I always start again from the beginning with tc qdisc del dev [root@amd /home/andy/Qos]# tc -V tc utility, iproute2-ss050330 [root@amd /home/andy/Qos]# tc qdisc add dev eth0 root handle 1:0 htb [root@amd /home/andy/Qos]# tc filter add dev eth0 parent 1:0 protocol arp u32 match u32 0 0 [root@amd /home/andy/Qos]# tc -s filter ls dev eth0 filter parent 1: protocol arp pref 49152 u32 filter parent 1: protocol arp pref 49152 u32 fh 800: ht divisor 1 filter parent 1: protocol arp pref 49152 u32 fh 800::800 order 2048 key ht 800 bkt 0 (rule hit 0 success 0) match 00000000/00000000 at 0 (success 0 ) [root@amd /home/andy/Qos]# ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1): 56 data bytes 64 bytes from 192.168.0.1: icmp_seq=0 ttld time=1.319 ms 64 bytes from 192.168.0.1: icmp_seq=1 ttld time=0.295 ms 64 bytes from 192.168.0.1: icmp_seq=2 ttld time=0.311 ms --- 192.168.0.1 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/stddev = 0.295/0.642/1.319/0.479 ms [root@amd /home/andy/Qos]# tc -s filter ls dev eth0 filter parent 1: protocol arp pref 49152 u32 filter parent 1: protocol arp pref 49152 u32 fh 800: ht divisor 1 filter parent 1: protocol arp pref 49152 u32 fh 800::800 order 2048 key ht 800 bkt 0 (rule hit 1 success 0) match 00000000/00000000 at 0 (success 1 ) [root@amd /home/andy/Qos]# tc -V tc utility, iproute2-ss050330 Andy. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
