Hello,
I have wrote some scripts to shape about 1000
workstations.
My config:
Pentium IV - 2GHz, 1Gb RAM, RedHat Enterprise
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
troubles with showing running configuration.
# Init shaper root for dev eth0
tc qdisc add dev eth0 root handle 2: htb default
200
# Default shaper for dev eth0 tc class add dev eth0 parent 2:0 classid 2:200 htb rate 100Mbit prio 10 tc qdisc add dev eth0 parent 2:200 sfq perturb 10 # Init NET1 shaper for dev eth0 , rate 30Mbit
, ceil 40Mbit
tc class add dev eth0 parent 2:0 classid 2:30 htb rate 30Mbit ceil 40Mbit prio 1 tc qdisc add dev eth0 parent 2:30 sfq perturb 10 tc filter add dev eth0 parent 2:0 protocol ip prio 1 u32 match ip src 192.168.1.0/24 flowid 2:30 # Init NET2 shaper for dev eth0 , rate 30Mbit

tc qdisc add dev eth0 parent 2:1001 sfq perturb 10 tc filter add dev eth0 parent 2:30 protocol ip prio 1 u32 match ip dst 192.168.0.1/32 flowid 2:1001 # User 1 - NET2

tc class add dev eth0 parent 2:40
classid 2:2002 htb rate 32Kbit ceil 256Kbit quantum 1514
tc qdisc add dev eth0 parent 2:2002 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 2:2002 At this point everything work fine, both User 1 and User 2 can get close to
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 u32 filter parent 2: protocol ip pref 1 u32 fh 802: ht divisor 1 filter parent 2: protocol ip pref 1 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid 2:2001 match c0a80001/ffffffff at 16 filter parent 2: protocol ip pref 1 u32 fh 802::801 order 2049 key ht 802 bkt 0 flowid 2:2002 match c0a80002/ffffffff at 16 filter parent 2: protocol ip pref 1 u32 fh 801: ht divisor 1 filter parent 2: protocol ip pref 1 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 2:1001 match c0a80001/ffffffff at 16 filter parent 2: protocol ip pref 1 u32 fh 801::801 order 2049 key ht 801 bkt 0 flowid 2:1002 match c0a80002/ffffffff at 16 filter parent 2: protocol ip pref 1 u32 fh 800: ht divisor 1 filter parent 2: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 2:30 match c0a80100/ffffff00 at 12 filter parent 2: protocol ip pref 1 u32 fh 800::801 order 2049 key ht 800 bkt 0 flowid 2:40 match c0a80200/ffffff00 at 12 It's look like ALL filters are attached to root class 2: which is not true,
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 u32 filter protocol ip pref 1 u32 fh 802: ht divisor 1 filter protocol ip pref 1 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid 2:2001 match c0a80001/ffffffff at 16 filter protocol ip pref 1 u32 fh 802::801 order 2049 key ht 802 bkt 0 flowid 2:2002 match c0a80002/ffffffff at 16 filter protocol ip pref 1 u32 fh 801: ht divisor 1 filter protocol ip pref 1 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 2:1001 match c0a80001/ffffffff at 16 filter protocol ip pref 1 u32 fh 801::801 order 2049 key ht 801 bkt 0 flowid 2:1002 match c0a80002/ffffffff at 16 filter protocol ip pref 1 u32 fh 800: ht divisor 1 filter protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 2:30 match c0a80100/ffffff00 at 12 filter protocol ip pref 1 u32 fh 800::801 order 2049 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 divisor 1 filter protocol ip pref 1 u32 fh 802::800 order 2048 key ht 802 bkt 0 flowid 2:2001 match c0a80001/ffffffff at 16 filter protocol ip pref 1 u32 fh 802::801 order 2049 key ht 802 bkt 0 flowid 2:2002 match c0a80002/ffffffff at 16 filter protocol ip pref 1 u32 fh 801: ht divisor 1 filter protocol ip pref 1 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 2:1001 match c0a80001/ffffffff at 16 filter protocol ip pref 1 u32 fh 801::801 order 2049 key ht 801 bkt 0 flowid 2:1002 match c0a80002/ffffffff at 16 filter protocol ip pref 1 u32 fh 800: ht divisor 1 filter protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 2:30 match c0a80100/ffffff00 at 12 filter protocol ip pref 1 u32 fh 800::801 order 2049 key ht 800 bkt 0 flowid 2:40 match c0a80200/ffffff00 at 12 I read in lartc.org that filter can be attached to any class, not only to
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
between "parent 2:0" and "fh 800::". Logicaly "parent 2:30" => "fh 801::" and
"parent 2:40" => "fh 802::".
What I'm missing?

Svetozar
