Iam resending this mail for the third time, I request you to please respond ASAP.
Iam stucked as my traffic control is not working, I just tried first with incoming traffic shaping, below is the test setup and rules applied. Your valuable suggestion will surely help me and make it right.
Traffic Control is not taking place after applying the below rules. Here follows the test setup:-
1. The linux m/c 's eth0(100Mbits, WAN) is connected to 128 Kbits ADSL and eth1 to the LAN.
2. I tried doing traffic control for incoming(at eth1).
3. In LAN, I connected 3 m/c's(all linux).
4. The ISP rate taken is 97% of 128Kbits.
5. Bandwidth Monitoring is done by using IPTraf on each LAN m/c's.
Here are the rules Iam applying to control incoming traffic at LAN interface(eth1) for LAN users. Here actual Isp rate = 128Kbit, rate taken = 97% of 128Kbit, eth1 ip is 192.168.5.1
/* root qdisc */ tc qdisc add dev eth1 root handle 1: cbq bandwidth 100Mbit avpkt 1000 cell 8
/* Parent Class */ tc class add dev eth1 parent 1:0 classid 1:1 cbq bandwidth 100Mbit rate 124Kbit weight 12Kbit prio 3 allot 1514 cell 8 maxburst 10 avpkt 1000 bounded /* Whether should I place the below filter for Parent class..??? tc filter add dev eth1 parent 1:0 protocol ip prio 3 u32 match ip src 0/0 match ip dst 0/0 classid 1:1 */
/* Child Classes */
/* 1st LAN user<192.168.5.2> = 37Kbit */ tc class add dev eth1 parent 1:1 classid 1:2 cbq bandwidth 100Mbit rate 37Kbit weight 3Kbit prio 3 allot 1514 cell 8 maxburst 10 avpkt 1000 tc filter add dev eth1 parent 1:1 protocol ip prio 3 u32 match ip src 0/0 match ip dst 192.168.5.2 classid 1:2
/* 2nd LAN user<192.168.5.3> = 24Kbit */ tc class add dev eth1 parent 1:1 classid 1:3 cbq bandwidth 100Mbit rate 24Kbit weight 2Kbit prio 3 allot 1514 cell 8 maxburst 10 avpkt 1000 tc filter add dev eth1 parent 1:1 protocol ip prio 3 u32 match ip src 0/0 match ip dst 192.168.5.3 classid 1:3
/* 3rd LAN user<192.168.5.4> = 12Kbit */ tc class add dev eth1 parent 1:1 classid 1:4 cbq bandwidth 100Mbit rate 12Kbit weight 1Kbit prio 3 allot 1514 cell 8 maxburst 10 avpkt 1000 tc filter add dev eth1 parent 1:1 protocol ip prio 3 u32 match ip src 0/0 match ip dst 192.168.5.4 classid 1:4
/* Default : Rest/Other traffic = 51Kbit*/ tc class add dev eth1 parent 1:1 classid 1:5 cbq bandwidth 100Mbit rate 51Kbit weight 5Kbit prio 3 allot 1514 cell 8 maxburst 10 avpkt 1000 tc filter add dev eth1 parent 1:1 protocol ip prio 3 u32 match ip src 0/0 match ip dst 0/0 classid 1:5
I have few observations and queries, as follows:--
1.In my test setup the ISP rate is fluctuating in the range of 21Kbits to 131 Kbits for 128Kbits ADSL.
2. I have not added any filter for the parent class. Is it required...? What happens if I add...?
3. Is "iptraf " tool OK for monitoring the distribution of bandwidth on each LAN m/c.
4. In case, if I shape outgoing traffic on eth0 interface, whether shall I take outgoing and incoming ISP rate's in 30:70 ratio, i.e 30% if 128Kbits for
outgoing Qdisc(eth0) and 70% for incoming Qdisc(eth1). As 128 Kbits rate being asyncronous(ADSL).
Can you pls guide me where am I going wrong..? Do I continue using CBQ or try instead HTB rules.
