Re: [LARTC] QoS on data and voice traffic
Hi, You are wrong! The packets must spend less time in your box for 0x08 class. So, if you are using cbq and sfq I don't belive that you will have good results. First you need a scheduler between 0x08 class and 0x00 like PRIO. You can use sfq for 0x00 class or tbf to limit the bandwidth. For 0x08 try to use pfifo. Also you can do the same configuration using htb. Please, for 0x08, use pfifo and for 0x00 sfq!

[LARTC] iptables: No chain/target/match by that name
Hi all, I installed linux kernel 2.4.18 and iptables 1.2.6a with patches htb3.3_tc.dif iptables-1.2.6a-imq.diff-3 sch_generic.diff I compiled everything without problems. When I tried to run some examples I received this message: ./iptables -t mangle -A prerouting -i eth3 -j IMQ iptables: No chain/target/match by that name I looked for imq.o and I tried insmod imq and I received those messages: /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_unregister_queue_handler_R4df6e6de /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol unregister_netdev_Rf7112b47 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol skb_under_panic_R14a04476 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_register_queue_handler_R9d33fd20 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol irq_stat_R79a4281c /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_unregister_hook_Rd74167f6 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_register_hook_R88672625 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol register_netdev_R20a39df5 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol skb_clone_R3e70c0f3 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol nf_reinject_Rb7e7232a /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol qdisc_restart_R5633d4d0 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol __kfree_skb_R57528140 /lib/modules/2.4.18/kernel/drivers/net/imq.o: unresolved symbol netdev_finish_unregister_R9f5d09d5 Where is the problem?

Re: [LARTC] Ingress utilization problem
Hi Alexey, I read the paper of Werner Almesberger. I didn' t understand if there are multiple instances of ingress queueing discipline. Can you be more specific? Also I want to do marking operation in ingress interface. How do I do?

[LARTC] Ingress utilization problem
Hi, I have one router with 4 interfaces: Input1 / out - R - Input2 \ Input3 The flows sense is: Input1 -> output; Input2->out; Input3->out; I want to do classification, shaping and marking in each In* interface and some queueing management in out interface. For In* interfaces I tried to use the following script: #!/bin/sh DEV1="dev eth3" # In1 DEV2="dev eth2" # In2 DEV3="dev eth4" # In3 DEV4="dev eth1" # out tc qdisc del $DEV1 ingress tc qdisc del $DEV2 ingress tc qdisc del $DEV3 ingress tc qdisc del $DEV4 root # initialisation part tc qdisc add $DEV1 ingress tc qdisc add $DEV2 ingress tc qdisc add $DEV3 ingress tc qdisc add $DEV4 root handle 1:0 cbq bandwidth 10Mbit avpkt 1500 cell 8 # for interface In1 (here is DEV1) # shaping + classification tc filter add $DEV1 parent :0 protocol ip prio 1 u32 match ip dst 192.168.3.6 match ip dport 6970 0x police rate 500Kbit burst 30K drop flowid 1:1 tc filter add $DEV1 parent :0 protocol ip prio 1 u32 match ip src 192.168.9.17 match ip dport 5050 0x police rate 500Kbit burst 6K drop classid 1:2 tc filter add $DEV1 parent :0 protocol ip prio 1 u32 match ip src 192.168.9.17 match ip sport 80 0x police rate 300Kbit burst 6K drop classid 1:3 # marking with tos field # Somebody has an I ideea how it should be done? #for interface In2 (here is DEV2) . #for interface In3 (here is DEV3) . #for interface out (here is DEV4) tc class add $DEV4 parent 1:0 classid 1:1 cbq bandwidth 10Mbit rate 250Kbit avpkt 1500 allot 1514 mpu 64 prio tc qdisc add $DEV4 parent 1:1 tbf rate 1Mbit burst 20kbit limit 20kb tc class add $DEV4 parent 1:0 classid 1:2 cbq bandwidth 10Mbit rate 300Kbit avpkt 1500 allot 1514 mpu 64 prio 2 tc qdisc add $DEV4 parent 1:2 gred setup DPs 1 default 1 grio tc qdisc change $DEV4 parent 1:2 gred limit 10KB min 2KB max 6KB avpkt 1500 burst 4 bandwidth 10Mbit DP 1 probability 0.02 prio 2 tc class add $DEV4 parent 1:0 classid 1:3 cbq bandwidth 10Mbit rate 700Kbit avpkt 1500 allot 1514 mpu 64 prio 2 tc qdisc add $DEV4 parent 1:3 gred setup DPs 1 default 1 grio tc qdisc change $DEV4 parent 1:3 gred limit 10KB min 2KB max 6KB avpkt 1500 burst 4 bandwidth 10Mbit DP 1 probability 0.02 prio 2 So, when I start the script and provision the In interface with ingress task the system is frozen! Why? Can anybody explain me? Also, I don't have any ideea how to mark the packets at the ingress. I tried to use dsmark queueing discipline but I can't use it at the ingress. Have you another ideea?
