Hi,
I'm using a script:

#!/bin/bash
NETZWERK_DEVICE="eth0"
OUT_REMOTE_SPEED_MAX="7500kbit"
OUT_LOCAL_SPEED_MAX="80000kbit"
OUTGOING_SPEED_3="$1"
INCOMING_SPEED_1="$1"
INCOMING_SPEED_2="200kbit"


/sbin/tc qdisc del dev ${NETZWERK_DEVICE} root 2> /dev/null

/sbin/tc qdisc add dev ${NETZWERK_DEVICE} root handle 1:0 htb default 1

/sbin/tc class add dev ${NETZWERK_DEVICE} parent 1:0 classid 1:1 htb
rate ${OUT_REMOTE_SPEED_MAX}

This is OK in behavior.

Best regards
Helmut Drodofsky

Viele Gr??e
