Tc: how to limit the bandwidth to the interface?

Question

linux

Hello everyone
I'm trying to cut down the outgoing speed to the eth0 interface.
It looks like it should work like this:

/sbin/tc qdisc add dev eth0 root handle 1: htb default 30<br/>
/sbin/tc class add dev eth0 parent 1: classid 1:30 htb rate 2mbit

But doesn't work. The interface sends traffic at full speed. Tell me, please, what am I doing wrong?

Answer 1

On my router like this:
# enter the guaranteed and maximum interface bandwidth
tc class add dev $WAN parent 1: classid 1:1 htb rate 5mbit ceil 5mbit

On one of the customer's servers, the following tc configuration script is used, if necessary, I can paint the details. Contact.
#!/bin/bash
tc qdisc add dev eth2 root handle 1: htb default 10 #Корневая дисциплина, с указание класса по умолчания не
попавшего ни под один фильтр
tc class add dev eth2 parent 1: classid 1:1 htb rate 4096kbit #Корневой класс отвечающий за общую пропускную
cпособность
tc class add dev eth2 parent 1:1 classid 1:10 htb rate 64kbit ceil 150kbit prio 7 #класс с наименьшим приоритетом
tc qdisc add dev eth2 parent 1:10 handle 10: sfq perturb 10
