CLASSYFY and MARK are not working on a normal Routing

Hi LQ people, please need your help related to a script.

I already try to LARC mailist, and try to subscript myself, without success.

I need to shape the bandwidth to a very large numbers of IPs in severals VLANs with normal routin (No Nat, and No Firewalling)
The traffic are not shaped....

I'm doing the next:
Make a base qdisc

Code:

tc qdisc add dev $iface root handle 1: htb

Then make a base class to send all national traffic

Code:

tc class add dev $iface parent 1: classid 1:1 htb rate 1gbit.

Next I iterate over a lists of nets to salve national traffic (disable for now, until all works)

Then I create a base class and qdisc per Range I mean ...

Code:

tc class add dev $iface parent 1:  classid 1:$clase htb rate 1gbit  # where $clase is 224 or 225... (C class address)
   tc qdisc add dev $iface parent 1:$clase handle $clase: htb

Next I iterate with every IP

Code:

tc class add dev $iface parent $clase: classid $clase:$n htb rate 256kbit

To be more clare.
If I get a IP 200.114.225.4

Code:

tc class add dev $iface parent 1:  classid 1:225 htb rate 1gbit  ### base
  tc qdisc add dev $iface parent 1:225 handle 225: htb  # to by more "nemotechnical"

  tc class add dev $iface parent 225: classid 225:4 htb rate 256kbit  ##  4 is for 225.'4'  another nemo

Then I try with CLASSIFY and didn't work
Then I try with MARK and don't work either -- whit this filter:

Code:

tc filter add dev $iface protocol ip parent $clase:$n prio 0 handle $clase$n fw flowid $clase:$n

I don't know really where is my error if any,

Can you please give me an idea why this are not working????

Thanks

PS: I'm sorry if my very poor english disturbing you in any way.

you should verify this, but I think that tc only reads the mark. use netfilter (iptables) to set the mark.

Thank for answer me

maybe I don't be clear enough

I already try both, the CLASSIFY and the MARK modules of iptables

the first one:

Code:

iptables -t mangle -A POSTROUTING -d $cut -j CLASSIFY --set-class $clase:$n

Whete $cut is the IP address

And the second:

Code:

iptables -t mangle -A FORWARD -d $cut -j MARK --set-mark $clase$n

Then I put the "tc filter ..."

Again thanks
