After I remove a
filter, I seem to be loosing my "parents" class shaping rules that will
return a filter to default after removing just the filter or both. Sorry, this
is hard to say.
I create a Class,
give it a default Class and one "special" Class with a "C"class filter. Then I
remove that "special" IP filter then class. Should that IP, that is within the
"C" class range, be reduced to the parent's default Class
rate?
I will try to map
the question...

$TC filter add dev eth0 pref 1 parent 1: protocol ip u32 flowid 1:10 match ip dst 10.10.0.0/16

----------------------------------------
#

----------------------------------------
# 10.10.3.0/24 -
Test
$TC class add dev
eth0 parent 10: classid 10:3 htb rate 100Mbit quantum
1500
$TC filter add dev eth0 pref 1 parent 10: protocol ip u32 flowid 10:3 match ip dst 10.10.3.0/24
$TC filter add dev eth0 pref 1 parent 10: protocol ip u32 flowid 10:3 match ip dst 10.10.3.0/24
$TC
qdisc add dev eth0 parent 10:3 handle 103: htb rate 100Mbit r2q
100
----------------------------------------
----------------------------------------
# Default
$TC class add dev eth0 parent 103: classid 103:0 htb rate 40Kbit quantum
1500
----------------------------------------
----------------------------------------
# Special
$TC class add dev eth0 parent 103: classid 103:2 htb rate 768Kbit quantum
1500
$TC filter add dev eth0 pref 1 parent 103: protocol ip u32 flowid 103:2 match ip
dst
10.10.3.199/32
----------------------------------------
----------------------------------------
Everything works
fine until I remove the bottom filter. Then that IP goes back 2 default classes.
Now if I rebuild the entire thing again, and leave out the "special" class
identifier, it works. 10.10.3.199 only gets the 40Kbit.
