Linux tc流控问题

choumin

#!/bin/sh
dev=vEth0
total_bandwidth=100Mbit
default_bandwidth=10Mbit
rate=30Mbit
ifconfig vEth0 0 up
ifconfig vEth1 0 up
brctl addif br1 vEth0
brctl addif br1 vEth1
tc qdisc del dev $dev root
tc qdisc add dev $dev root handle 1: htb default 9
tc class add dev $dev parent 1:0 classid 1:1 htb rate $total_bandwidth ceil $total_bandwidth burst 15k
tc class add dev $dev parent 1:0 classid 1:9 htb rate $default_bandwidth ceil $default_bandwidth burst 15k
tc qdisc add dev $dev parent 1:1 handle 2: htb default 1
tc class add dev $dev parent 2:0  classid 2:1 htb rate $rate ceil $rate burst 15k
tc qdisc add dev $dev parent 2:1 tbf rate 20Mbit mtu 100kbit burst 15k latency 10ms
tc filter add dev $dev parent 1:0 protocol ip handle 1 fw class 2:1
请大家帮我看看，上边的脚本有没有问题，为什么符合要求的数据包始终无法进入2:1类？若把最后一条的class 2:1改为class 1:1就正确了，这是为什么？
