[LARTC] htb parameter problem

So I do that:

....................

tc class add dev eth1 parent 30:100 classid 30:1000 htb rate 12800kbps ceil 51200kbps prio 1
tc qdisc add dev eth1 parent 30:1000 sfq

...................

tc -s -d class ls dev eth1

class htb 30:100 parent 30:10 rate 200Mbit ceil 400Mbit burst 263690b/8 mpu 0b cburst 525808b/8 mpu 0b level 5
 Sent 53850 bytes 719 pkts (dropped 0, overlimits 0)
 lended: 0 borrowed: 0 giants: 0
 tokens: 8239 ctokens: 8216

class htb 30:1000 parent 30:100 leaf 8012: prio 1 quantum 200000 rate 100Mbit ceil 400Mbit burst 132644b/8 mpu 0b cburst 525808b/8 mpu 0b level 0
 Sent 13944 bytes 116 pkts (dropped 0, overlimits 0)
 lended: 116 borrowed: 0 giants: 0
 tokens: 8287 ctokens: 8216


How to do obtain below result:



I read from www.docum.org have problem about parameter:

Frist :

The same story goes for ceil and cburst, you don't want the class to send more packets then it's ceil allows. So removing the cburst is a good choice for that case. 

Second:

Packets that are sent when the class is allowed to send, are still matched against rate/ceil/burst/cburst. So a big quantum will not create bursts if you don't allow it with the burs/cburst parameters.

 : tc class add dev eth1 parent 30:100 classid 30:1000 \
 :    htb rate 12800kbps ceil 51200kbps prio 1
 : tc qdisc add dev eth1 parent 30:1000 sfq

Whoa!!  Are you *sure* you mean 12800 kilobytes per second and 51200 kilo
bytes per second?  Just double-checking.

This sort of number looks quite similar to what I call a 128k / 512k line.
I would specify these rates as follows:

 128kbit and 512kbit

But maybe you really mean:

 12800kbit and 51200kbit

Judging from your "tc -s" output, you have a large pipe to the 'net.

Maybe it was locally cached ?
An other question, are you sure each packets ends in a class?  I never see 
your marking rules and you don't specified a default class.

Don't worry about these numbers :)
ctokens < 0 means the class sent more then the ceil because parent child 
classes are asking too much bandwidth.  Same for tokens and rate.

If I want to fixate every class bandwidth. not lended and not borrow .How to do it.

cburst play tricks??
On www.docum.org's FAQ have :

The same story goes for ceil and cburst, you don't want the class to send more packets then it's ceil allows. So removing the cburst is a good choice for that case.

instead of --dport ftp-data/ftp use -m helper --helper "ftp". Match for 
port does not work because of the nature of ftp. (passive mode) This can
be tricky.

Re: [LARTC] htb parameter problem

> I don't know about it.why do that? How to it?
By specifying a default class (see comments below) or a "catch all rules".  I 
see you use the fw rule.  If you add 

iptables -t mangle -A FORWARD -o eth0 -s 0/0  -j MARK --set-mark 1
iptables -t mangle -A PREROUTING -i eth0 -s 0/0 -j MARK --set-mark 1

as the first iptables rules, all packets are marked (you can overwrite this 
mark with the other iptalbes rules).  And if you add an extra filter rule 
that puts the packets marked with 1 in a class, you have a "catch all rule".  
You can also add a "catch all" u32 filter rule as the last filter.

> > and you don't specified a default class.
> I don't know about it and why do that ? how to do it?
If you add the htb qdisc, you can specify a default class.  Like
tc qdisc add dev eth1 root handle 10: htb default 20
So 10:20 is the default class.  If a packet is not matched by any filter, it 
ends in the default class.  It's also best to specify a default class so you 
know all the packets are ending in a class.

By not specifying a ceil parameter.  So rate = ceil.  Or of course you can add 
a ceil parameter like 
tc class add dev eth0 parent 10:1 classid 10:10 htb rate 3mbit ceil 3mbit

Cburst and burst is for something else.  That can be used if you want a class 
to be able to "break" the rate and ceil limitations.  If you want the ceil 
parameter to be respected very strictly so the class never can send more then 
it's ceil, you have to remove the cburst parameter if you add a class so htb 
can calculate the smalles one for you.

 My tc commands:
 tc class add dev eth1 parent 30: classid 30:1 htb rate 10kbps ceil 10kbps
 tc class add dev eth1 parent 30:1 classid 30:10 htb rate 5kbps ceil 5kbps


why it have the cburst parameter ?
# tc -s class ls dev eth1
 class htb 30:1 root rate 80Kbit ceil 80Kbit burst 1701b cburst 1701b
 Sent 3241503 bytes 55558 pkts (dropped 0, overlimits 0)
 lended: 0 borrowed: 0 giants: 0
 tokens: 132320 ctokens: 132320
My tc command howto drop cburst parameter?

You need a minimal cburst parameter.  If you don't specify one, htb will 
calculated the smalles possible one for you.  Same for burst.
