Hello,
 
I have wrote some scripts to shape = about 1000=20 workstations.
My config:
Pentium IV - 2GHz, 1Gb RAM, RedHat = Enterprise=20 Advanced Server 3, kernel 2.4.21-9.EL, = iproute-2.4.7-11.30E.1
2 Gigabit Lan cards in bridge = mode.
 
I use htb. Everything work fine, but I = have=20 troubles with showing running configuration.
 
# Init shaper root for dev = eth0
tc qdisc add dev eth0 root handle 2: = htb default=20 200
# Default shaper for dev eth0

# User 2 - NET1

tc qdisc add = dev=20 eth0 parent 2:1002 sfq perturb 10

tc filter add dev eth0 parent  = 2:40  protocol ip prio 1 u32 match ip dst 192.168.0.2/32 flowid=20 2:2002
 
At this point everything work fine, both User 1 and User 2 can get = close to=20 256kbit from both networks in same time.
But when I try to show filters I get:
 
# tc filter ls dev eth0
filter parent 2: protocol ip pref 1=20 u32
filter parent 2: protocol ip pref 1 u32 fh 802: ht divisor = 1
filter=20 parent 2: protocol ip pref 1 u32 fh 802::800 order 2048 key ht 802 bkt 0 = flowid=20 2:2001
  match c0a80001/ffffffff at 16
filter parent 2: = protocol ip=20 pref 1 u32 fh 802::801 order 2049 key ht 802 bkt 0 flowid = 2:2002
  match=20 c0a80002/ffffffff at 16
filter parent 2: protocol ip pref 1 u32 fh = 801: ht=20 divisor 1
filter parent 2: protocol ip pref 1 u32 fh 801::800 order = 2048 key=20 ht 801 bkt 0 flowid 2:1001
  match c0a80001/ffffffff at = 16
filter=20 parent 2: protocol ip pref 1 u32 fh 801::801 order 2049 key ht 801 bkt 0 = flowid=20 2:1002
  match c0a80002/ffffffff at 16
filter parent 2: = protocol ip=20 pref 1 u32 fh 800: ht divisor 1
filter parent 2: protocol ip pref 1 = u32 fh=20 800::800 order 2048 key ht 800 bkt 0 flowid 2:30
  match=20 c0a80100/ffffff00 at 12
filter parent 2: protocol ip pref 1 u32 fh = 800::801=20 order 2049 key ht 800 bkt 0 flowid 2:40
  match = c0a80200/ffffff00 at=20 12
It's look like ALL filters are attached to root class 2: which is = not true,=20 becouse all work as expected.
If I try to specify classid in tc result is:
 
#tc filter ls dev eth0 parent 2:30
filter protocol ip pref 1=20 u32
filter protocol ip pref 1 u32 fh 802: ht divisor 1
filter = protocol ip=20 pref 1 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid = 2:2001
  match=20 c0a80001/ffffffff at 16
filter protocol ip pref 1 u32 fh 802::801 = order 2049=20 key ht 802 bkt 0 flowid 2:2002
  match c0a80002/ffffffff at = 16
filter=20 protocol ip pref 1 u32 fh 801: ht divisor 1
filter protocol ip pref 1 = u32 fh=20 801::800 order 2048 key ht 801 bkt 0 flowid 2:1001
  match=20 c0a80001/ffffffff at 16
filter protocol ip pref 1 u32 fh 801::801 = order 2049=20 key ht 801 bkt 0 flowid 2:1002
  match c0a80002/ffffffff at = 16
filter=20 protocol ip pref 1 u32 fh 800: ht divisor 1
filter protocol ip pref 1 = u32 fh=20 800::800 order 2048 key ht 800 bkt 0 flowid 2:30
  match=20 c0a80100/ffffff00 at 12
filter protocol ip pref 1 u32 fh 800::801 = order 2049=20 key ht 800 bkt 0 flowid 2:40
  match c0a80200/ffffff00 at = 12
"parent" is disapearing from list, but I see ALL attached = filters.
 
If I try to see 2:40 class result is exactly the same:
 
#tc filter ls dev eth0 parent 2:40
filter protocol ip pref 1 u32
filter protocol ip pref 1 u32 fh = 802: ht=20 divisor 1
filter protocol ip pref 1 u32 fh 802::800 order 2048 key ht = 802 bkt=20 0 flowid 2:2001
  match c0a80001/ffffffff at 16
filter = protocol ip=20 pref 1 u32 fh 802::801 order 2049 key ht 802 bkt 0 flowid = 2:2002
  match=20 c0a80002/ffffffff at 16
filter protocol ip pref 1 u32 fh 801: ht = divisor=20 1
filter protocol ip pref 1 u32 fh 801::800 order 2048 key ht 801 bkt = 0=20 flowid 2:1001
  match c0a80001/ffffffff at 16
filter protocol = ip pref=20 1 u32 fh 801::801 order 2049 key ht 801 bkt 0 flowid 2:1002
  = match=20 c0a80002/ffffffff at 16
filter protocol ip pref 1 u32 fh 800: ht = divisor=20 1
filter protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt = 0=20 flowid 2:30
  match c0a80100/ffffff00 at 12
filter protocol = ip pref 1=20 u32 fh 800::801 order 2049 key ht 800 bkt 0 flowid 2:40
  match=20 c0a80200/ffffff00 at 12
 
I read in lartc.org that filter can be attached to any class, not = only to=20 root. I make my traffic control acording to that. And everything is = fine.
I see thah filters are grouped. There is "fh 800::", but where is = relation=20 between "parent 2:0" and "fh 800::". Logicaly "parent 2:30" =3D> "fh = 801::" and=20 "parent 2:40" =3D> "fh 802::". 
 
What I'm missing?
