Dear All,

Sorry if my question here ever asked before by someone else.
I have configuration like this :
                     |---------trunking------|
                    V  eth0         eth1  V
         router<--->bridge with htb<--->switch
202.xx.xx.227

#!/bin/bash
tc qdisc del dev eth0 root handle 1:
tc qdisc add dev eth0 root handle 1: htb default 10
tc class add dev eth0 parent 1: classid 1:1 htb rate 32kbit ceil 32kbit
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 24kbit ceil 24kbit
tc class add dev eth0 parent 1:1 classid 1:20 htb rate 8kbit ceil 8kbit
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst 202.xx.xx.227 flowid 1:20

I already patch kernel and tc with htb3.6-020525.tgz from htb website.

Here is the result when there's traffic to 202.xx.xx.227, it should go to 1:20, but fill class 1:10 (red sign).

### eth0: queueing disciplines
qdisc htb 1: r2q 10 default 10 direct_packets_stat 0
 Sent 584256 bytes 881 pkts (dropped 0, overlimits 1113)
 backlog 35p

### eth0: traffic classes

### eth0: filtering rules
filter parent 1: protocol ip pref 1 u32
filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1
filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:20
  match ca2ba0e3/ffffffff at 16


Why when i put htb on eth0 to filter class 1:20 the shaping always goes to default class 1:10 not 1:20 class, the same problem occur when i put htb on eth1?
I already patch the kernel with 3c95x vlan patch too.
Any idea why the filter not working properly or i need another patch to get u32 working in bridging+trunking or i must replace u32 filter with fwmark from ebtables?

Thnx.
