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 qdisc add dev eth0 root handle 1: htb default 0 r2q 100
----------------------------------------
# Default
$TC class add dev eth0 parent 1: classid 1:0 htb rate 100Mbit
----------------------------------------
# 10.10.0.0/16
$TC class add dev eth0 parent 1: classid 1:10 htb rate 100Mbit quantum 1500
$TC filter add dev eth0 pref 1 parent 1: protocol ip u32 flowid 1:10
match ip dst 10.10.0.0/16
$TC qdisc add dev eth0 parent 1:10 handle 10: htb default 0 r2q 100
----------------------------------------
# Default
$TC class add dev eth0 parent 10: classid 10:0 htb rate 100Mbit
quantum 1500
----------------------------------------
# 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 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.
