but iam getting the folloing error

[root@bridge root]# modprobe imq numdevs=1
[root@bridge root]#  tc qdisc add dev imq0 handle 1: root htb default 1
[root@bridge root]#  tc class add dev imq0 parent 1: classid 1:1 htb rate
1mbit
[root@bridge root]#  tc qdisc add dev imq0 parent 1:1 handle 10: htb default
5
[root@bridge root]#  tc class add dev imq0 parent 10: handle 10:1 htb rate

This last line should be:

tc class add dev imq0 parent 10: classid 10:1 htb rate 256kbit burst 30k
prio 1
                                 ^^^^^^^

Hi thanks all for the help

i have added for egress filter

modprobe imq numdevs=1

 tc qdisc add dev imq0 handle 1: root htb default 1
 tc class add dev imq0 parent 1: classid 1:1 htb rate 100kbit

 tc qdisc add dev imq0 parent 1:1 handle 10: htb default 1
 tc class add dev imq0 parent 10: classid 10:10 htb rate 100kbit
 tc qdisc add dev imq0 parent 10:10 handle 20: sfq

 iptables -t mangle -A POSTROUTING -p tcp --dport 80 -j IMQ

 ip link set imq0 up


when i see the iptable -nxvL -t mangle,   iam not able to see the rule which
postrouting sending packets to IMQ

[root@bridge root]# iptables -nxvL -t mangle
Chain PREROUTING (policy ACCEPT 11798 packets, 1175157 bytes)
    pkts      bytes target     prot opt in     out     source
destination

Chain INPUT (policy ACCEPT 2674 packets, 162372 bytes)
    pkts      bytes target     prot opt in     out     source
destination

Chain FORWARD (policy ACCEPT 9509 packets, 1048840 bytes)
    pkts      bytes target     prot opt in     out     source

Chain OUTPUT (policy ACCEPT 1820 packets, 213096 bytes)

destination

Chain POSTROUTING (policy ACCEPT 11329 packets, 1261936 bytes)
    pkts      bytes target     prot opt in     out     source
destination



And iam not able to see any traffic ifconfig imq, its 0 bytes


imq0      Link encap:UNSPEC  HWaddr
00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
          UP RUNNING NOARP  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:30
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)




my setup is like this

my laptop---eth1(Bridge)eth0---Switch--Router--internet

when i have made the packets to jump to IMQ, i should see some traffic in
IMQ right ?
but iam not able to any traffic

any guidance will be great

You mixed handle and classid in your commands.

It's not such a good idea to add a htb qdisc to a htb class.  It will only 
create extra delays.

[LARTC] PROBLEM WITH IMQ

[s.az]

I want to shape the bandwith for only 2 PC's but  cannot make this work.

This is what i do ( i want to use imq for all this )

ip link set imq0 up

tc qdisc add dev imq0 root handle 1: htb default 2
tc class add dev imq0 parent 1: classid 1:1 htb rate 100kbit burst 6k prio 0
tc class add dev imq0 parent 1: classid 1:2 htb rate 50kbit burst 6k prio 2
tc filter add dev imq0 parent 1: protocol ip prio 1 u32 match ip src 
10.0.0.2 flowid 1:1

iptables -t mangle -A PREROUTING -i eth0 -p TCP -j IMQ --todev 0

using the 10.0.0.2 ip it always take the class 2 ( the default class ). 
it does not obey the filter.
What part it's wrong in this?

Thanks
