Wonder Shaper is good for two reasons, as the tool it is intended for
and as an example of how to combine the various LARTC commands. I've
read through LARTC a half dozen times and I'm still uncertain of how it
all works together. Luckily, Wonder Shaper is just right for what I need.
You probably want to look at how this part works:
# low priority source ports
NOPRIOPORTSRC=
# low priority destination ports
NOPRIOPORTDST=
for a in $NOPRIOPORTDST
do
tc filter add dev $DEV parent 1: protocol ip prio 14 u32 \
match ip dport $a 0xffff flowid 1:30
done
for a in $NOPRIOPORTSRC
do
tc filter add dev $DEV parent 1: protocol ip prio 15 u32 \
match ip sport $a 0xffff flowid 1:30
done
And this part:
# TOS Minimum Delay (ssh, NOT scp) in 1:10:
tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 \
match ip tos 0x10 0xff flowid 1:10
