[LARTC] Testing diferent bandwidths.

[Vitor Carlos Flausino <vflausino@xxxxxx>]

Hi!
I'm using class based queueing for testing how same applications work
with low bandwidth. So what I did was give this commands:

tc qdisc add dev eth0 root handle 10: cbq bandwidth 100Mbit avpkt 1000
tc qdisc add dev eth1 root handle 20: cbq bandwidth 100Mbit avpkt 1000

tc class add dev eth0 parent 10:0 classid 10:1 cbq bandwidth 100Mbit
rate 100Mbit allot 1514 weight 1Mbit prio 5 maxburst 20 avpkt 1000
tc class add dev eth1 parent 20:0 classid 20:1 cbq bandwidth 100Mbit
rate 100Mbit allot 1514 weight 1Mbit prio 5 maxburst 20 avpkt 1000

tc class add dev eth0 parent 10:1 classid 10:100 cbq bandwidth 100Mbit
rate 2Kbit allot 1514 weight 2Kbit prio 5 maxburst 20 avpkt 1000
isolated
tc class add dev eth0 parent 10:1 classid 10:200 cbq bandwidth 100Mbit
rate 102398Kbit allot 1514 weight 1022Kbit prio 5 maxburst 20 avpkt 1000
isolated
tc class add dev eth1 parent 20:1 classid 20:100 cbq bandwidth 100Mbit
rate 2Kbit allot 1514 weight 2Kbit prio 5 maxburst 20 avpkt 1000
isolated
tc class add dev eth1 parent 20:1 classid 20:200 cbq bandwidth 100Mbit
rate 102398Kbit allot 1514 weight 1022Kbit prio 5 maxburst 20 avpkt 1000
isolated

tc qdisc add dev eth0 parent 10:1 sfq quantum 1514b
tc qdisc add dev eth1 parent 20:1 sfq quantum 1514b

tc filter add dev eth0 parent 10:0 protocol ip prio 10 u32 match ip src
0.0.0.0/0 flowid 10:100
tc filter add dev eth1 parent 20:0 protocol ip prio 10 u32 match ip src
0.0.0.0/0 flowid 20:100

(has you can see I'm testing with bandwidth = 2K)

Now, WHY DOES NOT WORK? It seams that it using all 100Mbits
