Hi all, I'm experimenting with HTB and the prio parameter and it does not give me results I expect. I've created 4 HTB classes: 1:10 TCP ACKs (prio 0) 1:20 TCP traffic on dst port 10001 (prio 1) 1:30 TCP traffic on dst port 10000 (prio 2) 1:40 Default (prio 3) ceil and rate parameters are the same for all 4 classes (rate is 1000kbit and ceil is 55000kbit). Then I start 2 TCP flows on src/dst ports 10000 and 10001. The packets seem to be correctly classified by the filter (I get hits on classes 10, 20 and 30). The problem is that I get the same throughput on both TCP flows. Shouldn't I get about 1000kbit through class 30 and much more through class 20 since it has higher priority? Here's my setup script: #!/bin/sh /bin/tc qdisc add dev eth0 root handle 1: htb default 40 && \ /bin/tc class add dev eth0 parent 1:0 classid 1:1 htb rate 55000kbit ceil 55000kbit quantum 60000 && \ /bin/tc class add dev eth0 parent 1:1 classid 1:10 htb rate 1000kbit ceil 55000kbit prio 0 quantum 60000 && \ /bin/tc class add dev eth0 parent 1:1 classid 1:20 htb rate 1000kbit ceil 55000kbit prio 1 quantum 60000 && \ /bin/tc class add dev eth0 parent 1:1 classid 1:30 htb rate 1000kbit ceil 55000kbit prio 2 quantum 60000 && \ /bin/tc class add dev eth0 parent 1:1 classid 1:40 htb rate 1000kbit ceil 55000kbit prio 3 quantum 60000 && \ /bin/tc filter add dev eth0 parent 1:0 prio 99 handle 2: protocol ip u32 divisor 256 && \ /bin/tc filter add dev eth0 parent 1:0 protocol ip prio 10 u32 \ ht 2:0: \ match u8 0x06 0xff at 9 \ match u8 0x10 0xff at nexthdr+13 \ flowid 1:10 && \ /bin/tc filter add dev eth0 parent 1:0 protocol ip prio 10 u32 \ ht 2:0: \ match u8 0x06 0xff at 9 \ match u16 0x2711 0xffff at nexthdr+2 \ flowid 1:20 && \ /bin/tc filter add dev eth0 parent 1:0 protocol ip prio 10 u32 \ ht 2:0: \ match u8 0x06 0xff at 9 \ match u16 0x2710 0xffff at nexthdr+2 \ flowid 1:30 && \ /bin/tc filter add dev eth0 parent 1:0 protocol ip prio 99 u32 ht 800:: offset at 0 mask 0x0f00 shift 6 plus 0 match u8 0x40 0xf0 at 0 link 2: && \ /bin/tc qdisc add dev eth0 parent 1:10 handle 20: red limit 1000KB min 10KB max 300KB avpkt 1000 burst 100 probability 0.02 && \ /bin/tc qdisc add dev eth0 parent 1:20 handle 30: red limit 1000KB min 10KB max 300KB avpkt 1000 burst 100 probability 0.02 && \ /bin/tc qdisc add dev eth0 parent 1:30 handle 40: red limit 1000KB min 10KB max 300KB avpkt 1000 burst 100 probability 0.02 && \ /bin/tc qdisc add dev eth0 parent 1:40 handle 50: red limit 1000KB min 10KB max 300KB avpkt 1000 burst 100 probability 0.02 && \ Regards, Martin _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
