Dear all,
I'm making a script to implement DiffServ policies with HTB. Here it is :
if test $1 = "help" -o $1 = "h" -o $# != 5
then
echo "usage: ds.sh <DEVICE> <DS_RATE> <EF_RATE> <AF_RATE> <BE_RATE>"
exit
fi
DEV=$1
DS_RATE=$2
EF_RATE=$3
AF_RATE=$4
BE_RATE=$5
sync
tc qdisc del root dev $DEV
tc qdisc add dev $DEV root handle 1: htb default 1
tc class add dev $DEV parent 1: classid 1:1 htb rate $DS_RATE ceil $DS_RATE
tc class add dev $DEV parent 1:1 classid 1:10 htb rate $EF_RATE ceil $DS_RATE
tc class add dev $DEV parent 1:1 classid 1:11 htb rate $AF_RATE ceil $DS_RATE
tc class add dev $DEV parent 1:1 classid 1:12 htb rate $BE_RATE ceil $DS_RATE
# --- EF 1:10
#tc filter add dev $DEV parent 1:0 protocol ip prio 1 handle 0x2e tcindex
classid 1:10
# --- AF class 1:11
#tc filter add dev $DEV parent 1:0 protocol ip prio 1 handle 0xa tcindex
classid 1:11
My problem is that the data rate I've measured with generated high rate BE
traffic is not reduced to DS_RATE as I expected. The rate is well limited when
only the class 1:1 is defined. But when I change the script to include classes
1:10, 1:11 and 1:12, the rate is not controlled anymore.
If any idea, thanks in advance,
Sandrine
