Chain of HTB qdisc does not work

[Yuriy Ivkin <y.ivkin@xxxxxxxxxxxx>]

Greetings!

I configured a chain of htb qdisc's with classes: qdisc htb (1:0) ->
class htb (1:10) -> qdisc htb (10:0) -> class htb (10:1) -> multiple
class (10:1xxx - 10:2xxx).

`tc -s -d class show dev wg0`  show packets sent throug the leaf classes
(10:2xxx). But when I start a real test with iperf I do not see any
shaping. Traffic takes all available capacity.

What am I doing wrong ? Thanks in advance for your answers!

A part of the script, which activates shaping, is below.

#!/usr/bin/bash

TC="/usr/sbin/tc"
OUT_IF="wg0"

$TC qdisc del dev $OUT_IF root handle 1: htb default 50
$TC qdisc add dev $OUT_IF root handle 1: htb default 50

$TC class add dev $OUT_IF parent 1: classid 1:1 htb rate 1000Mbit ceil
1000Mbit

$TC class add dev $OUT_IF parent 1:1 classid 1:10 htb rate 250Mbit ceil
250Mbit
$TC qdisc add dev $OUT_IF parent 1:10 handle 10: htb default 50
$TC class add dev $OUT_IF parent 10: classid 10:1 htb rate 20Mbit ceil
20Mbit
$TC class add dev $OUT_IF parent 10: classid 10:2 htb rate 230Mbit ceil
230Mbit

for (( i=1; i <= 254; i++ ))
do
     $TC class add dev $OUT_IF parent 10:1 classid 10:1$i htb rate 1kbit
ceil 64kbit
     $TC class add dev $OUT_IF parent 10:2 classid 10:2$i htb rate

done
