bandwidth allocation ...

[JATINDER KUMAR]

Dear Friends.. Good day ..

i have a requirement .. in which i have a router which is having a big pipe of bandwidth is coming .. and now i have to allocate the bandwidth - 128K very exact to one of our client... not very sure how i can do this and how i can make sure this is working correctly and can also show this to client about the bandwidth allocated to him

please read below point and correct me if m wrong ...

1. from client rack / switch .. pull a wire and put it into our switch which then connecte to WAN router - not connecting client LAN directly to router becoz of port usage .. dont want to give single client a dedicated port .. inturn planning of using VLAN and then terminate from switch to router LAN interface.

2. configure routing + NAT and ACL (if required)

3. .................? this is missing .. how can i allocate him specific bandwidth based on his subnet .this router will be having multiple clients like this .. with their own subnets

Please advice. and if you have some sample configuration please share if u can .Thanks for the help

Hi Jatinder,

CAR (rate-limit) will work similar to MQC police, it will allow you to rate traffic based on ACLs both in and out direction, here are some useful links:

http://www.cisco.com/en/US/docs/ios/12_0/qos/configuration/guide/qccar.html

Check "Rate Limiting by Access List Example".

To control the downloading as well as the uploading, this config should should work:

Access-list 100 permit ip any any

Class-map client1

Match access-group 100

Policy-map p1

Class client1

Police 128000

Int x/x

Service policy p1 in

service policy p1 out

Thanks Edison for the reply...!!!

i tried exactly the same and then i went to speedtest.net and it didnt worked for me ... one more thing .. i dont want to limit any specific traffic .. it will be for all kind of traffic . but its not working .. can you please help

happiness always

Jatin

[Edison Ortiz]

Can you post your current config along with the 'show policy-map interface' output?

[JATINDER KUMAR]

sure Edison will do but by tomorrow.. if you want to understand my scenario i can write it for you ...or if you have couple of minutes you can read this thread of mine ...

https://supportforums.cisco.com/message/3501606#3501606

my network is my first comment in this thread .. please read.. if there is smthign i need to do for my particular scenario please advice .. thanks again for the help....

main aim is not to give client more then 128 or less then 128... from the total wan pipe

[Edison Ortiz]

I saw the thread but I need to see current configs and see if you are missing anything..

[JATINDER KUMAR]

ok Edison .. will do it tomorrow morning ... (already end of day in my country)

i also read a command rate-limit which is per interface...? this can work in my scenario .. what exactly the difference.. if you can suggest

[Edison Ortiz]

rate-limit is legacy QoS and I much rather use Modular QoS CLI (MQC) for new implementations.

[JATINDER KUMAR]

hi Edison sorry for the late reply.. please find attachments there are 4 files

1. Router config

2. show policy-map interface

3. speed test - Withour QoS

4. speed test - Withour QoS

i tested the solution which you gave me but no success.. secondly there are two more problems ..

1. dont know my internet is working fine with all the other public ips on this configuration but for this configurations its not working .. connection gets disconnected with an error server not found

2. i dont want other users to use this 128 kb bandwidth.. means if the pipe is 1mb other subnets or people connecting from other interface should get 1mb - 128 kb. i think for this i need to make one more policy map which will be for the bandwidth 1mb-128 and then assign it to my fe 0/1

Please suggest/.... thansk for the help
