======================
1. Real measurement of bw (also in Calculation in previous mail)
In my test the downstream bw was divided:
class real bw
----------------------------------------
class 1:10-RATE=4kbit....... 12 kbit/s
class 1:40-RATE=4kbit....... 12 kbit/s
class 1:80-RATE=15kbit...... 29.6 kbit/s
----------------------------------------
Used bw .................... 53.6 kbit/s
2. HTB script
----------------------
#!/bin/bash
# chkconfig: 2345 14 89
# description: sets up HTB traffic control and filters
#VLAN

BAND=56 #kbit/s
BURST=2
VBAND1=4
VBAND2=9
VBAND4=4
VBAND5=6
VBAND6=9
VBAND7=4

VBAND9=6
