[LARTC] tc does'nt limit the bandwidth!

[segun adesina]

Hi, good people!

I wanted to limit my 4 customers to 144, 16, 32, and
32kbps.
I used the following tc commands BUT IT FAILED TO
LIMIT each and everyone of them to its bandwidth.
 What am I doing wrong:

My tc scripts are:

tc qdisc add dev eth1 root handle 1: htb default 1
                       #Classes#
tc class add dev eth1 parent 1:    classid 1:1    htb
rate     9bps ceil    9bps  #Default
tc class add dev eth1 parent 1:    classid 1:100  htb
rate     9bps ceil    9bps  #ICMP


tc class add dev eth1 parent 1:    classid 1:5    htb
rate  144kbps ceil 256kbps  #customer A
tc class add dev eth1 parent 1:    classid 1:101  htb
rate   16kbps ceil  16kbps  #customer B
tc class add dev eth1 parent 1:    classid 1:111  htb
rate   32kbps ceil  32kbps  #customer C
tc class add dev eth1 parent 1:    classid 1:121  htb
rate   32kbps ceil  32kbps  #customer D

Can anyone help me on how to limit the the bandwidth
to these customers.
Regards.

Digihall7.

          ^^^^

9bps?  Shouldn't that be at least 256kbps?

Do you know that tc uses somewhat unconventional abbreviations? kbps
means kiloBYTEs per second and kbit means kiloBITs per second. That
would really screw up the limiting if you had that mixed up. Read the
"Units" secion of the man page.

This class has a higher ceiling than its rate, which means it is allowed
to "borrow" unused bandwidth from the other classes. I don't know if you
intended that.

All these classes are operating on eth1, and should restrict bandwidth
leaving that interface. If you want to restrict traffic moving in the
other direction, you may need a corresponding set of classes.

You haven't shown us any of your tc filter commands. If nothing I've
said above has helped any, then you probably have to give us more
information or we won't be able to find what's wrong.

Re: [LARTC] tc does'nt limit the bandwidth!

[Roy]

first you cant use limit of 9 bits /s it is 1 byte /s, so completely
unreasonable speed. set it to 50 bytes/s at least

another popstential problem that you are using independent root classes for
each client
that means they wont share bandwitch. customer a will always get 256 kbits
and others will get their ceil limit all time.

and my suggestion is to NOT touch default or you may have problems
if rate = ceil then just specify rate.

if you want your clients share bandwitch then you need to create one root
class and attach everyone to it.
this will look like this:


tc qdisc add dev eth1 root handle 1: htb default 1
                       #Classes#

tc class add dev eth1 parent 1:    classid 1:5    htb
rate  230kbps   #root (set rate to 80-90% of link capacity)

tc class add dev eth1 parent 1:5    classid 1:100  htb
rate     9bps ceil    9bps  #ICMP


tc class add dev eth1 parent 1:5    classid 1:100    htb
rate  144kbps ceil 230kbps  #customer A
tc class add dev eth1 parent 1:5   classid 1:101  htb
rate   16kbps   #customer B
tc class add dev eth1 parent 1:5    classid 1:111  htb
rate   32kbps  #customer C
tc class add dev eth1 parent 1:5    classid 1:121  htb
rate   32kbps  #customer D

b,c and d will get always and only rate amount of trafic

[LARTC] tc does'nt limit the bandwidth!

[segun adesina]

Good people,
I want to thank you all for your awesome help so far
and also want to make my problem clear to you all so
that I can get more definite help.

I have 256kpbs internet link to share among 4
customers- A\x176 burstable to 256; B\x16; C2; D2.

But the problem is that my script FAILED TO LIMIT
customers B, C,and D.

My complete tc scripts is as follows;

tc qdisc add dev eth1 root handle 1: htb default 1
                        #Classes
tc class add dev eth1 parent 1:    classid 1:1    htb
rate     9bps ceil    9bps  #Default
tc class add dev eth1 parent 1:    classid 1:100  htb
rate     9bps ceil    9bps  #ICMP
tc class add dev eth1 parent 1:    classid 1:5    htb
rate  176kbps ceil 256kbps  #Customer A
tc class add dev eth1 parent 1:    classid 1:101  htb
rate   16kbps ceil  16kbps  #Customer B
tc class add dev eth1 parent 1:    classid 1:111  htb
rate   32kbps ceil  32kbps  #Customer C
tc class add dev eth1 parent 1:    classid 1:121  htb
rate   32kbps ceil  32kbps  #Customer D
                        #Leafs
                          #  A   #
tc class add dev eth1 parent 1:5   classid 1:90  htb
rate 176kbps ceil 256kbps 
                  #Queues                   
tc qdisc add dev eth1 parent 1:11  handle 211: sfq
perturb 10                   #Customer A
tc qdisc add dev eth1 parent 1:101  handle 281: sfq
perturb 10                   # Customer B 
tc qdisc add dev eth1 parent 1:111  handle 282: sfq
perturb 10                   # Customer C 
tc qdisc add dev eth1 parent 1:121  handle 283: sfq
perturb 10                   # Customer D
                        #Ip Assignment#
U32="tc filter add dev eth1 protocol ip parent 1:0
prio 4 u32"
u32="tc filter add dev eth1 protocol ip parent 1:0
prio 0 u32"
                          # A #
$U32 match ip dst 200.200.200.11   flowid 1:11        
                            
$U32 match ip src 200.200.200.11   flowid 1:11
                        #Customer B#
$U32 match ip dst 172.16.0.11  flowid 1:101           
                        
$U32 match ip src 172.16.0.11  flowid 1:101
				#Customer C#
$U32 match ip dst 172.16.0.12  flowid 1:111           
                        
$U32 match ip src 172.16.0.12  flowid 1:111
				#Customer D#
$U32 match ip dst 172.16.0.13  flowid 1:121           
                        
$U32 match ip src 172.16.0.13  flowid 1:121
#virus ping 
$U32 match ip protocol 1 0xff  flowid 1:100 

What exactly am I doing wrong please?

Can anyone re-write it for me or give me a better one
please.

Kind regards.

Cheers!
