Hi Stef,

I'm using following commands (i'm trying to use it
with IMQ). I'm trying the example given in IMQ section
of adv-routing-howto doc.

# tc qdisc add dev imq0 root handle 1: htb default 11

# tc class add dev imq0 parent 1: classid 1:1 htb \
rate 4mbit burst 10k 

# tc class add dev imq0 parent 1:1 classid 1:10 \
htb rate 2mbit

# tc class add dev imq0 parent 1:1 classid 1:11 \
htb rate 2mbit 

# tc qdisc add dev imq0 parent 1:10 handle 10 pfifo
#tc qdisc add dev imq0 parent 1:11 handle 11: pfifo

# tc filter add dev imq0 parent 10:0 protocol ip \
prio 1 u32 match u32 00100000 00ff0000 at 0 \
flowid 1:10

All commands except the last one work fine.

Thanks for your help,
Praveen
