Hi all,

 I'm having a hell of a time getting my IFB to work. I know I've done this before, so I'm missing something stupid. Can anybody tell me what it might be?

Configs as follows:

 

--------

#!/bin/sh
modprobe ifb numifbs=1000
modprobe act_mirred
modprobe 8021q

 

brctl addbr br0
brctl setfd br0 0
brctl stp br0 off
brctl addif br0 eth1
brctl addif br0 eth2
ifconfig eth1 up
ifconfig eth2 up
ifconfig br0 up

 

tc qdisc add dev eth1 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8
tc qdisc add dev eth2 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8

 

ifconfig ifb0 up

 

tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8

 

tc class add dev ifb0 parent 1:0 classid 1:1 cbq bandwidth 100Mbit rate 100Kbit weight 10Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded isolated

 

tc qdisc add dev eth1 ingress
tc qdisc add dev eth2 ingress
tc filter add dev eth1 parent ffff: protocol ip prio 10 u32 match u32 0 0 action mirred egress redirect dev ifb0
tc filter add dev eth2 parent ffff: protocol ip prio 10 u32 match u32 0 0 action mirred egress redirect dev ifb0

 

tc filter add dev ifb0 parent 1:0 protocol ip prio 1 u32 match u32 0 0 flowid 1:1

--------------

 

By my reckoning, this should redirect all packets passing through eth2 and eth1 through the IFB, and put a rate limit on the IFB of 100Kbits/sec.

What have I missed?
