Hii Netpros,



Is this possible to configure the Service Policy(for Bandwidth) or Bandwidth Rate Limit for Single IP. For eg: If we want to configure the Service Policy(for Bandwidth) or Bandwidth Rate Limit of 2Mb for only IP " 10.10.10.3" on network  i.e the Host or device which is configured with this IP can access upto 2Mb only.


Actual Network :-   We need this to configure this for wireless customers, Actually we have created one Vlan 2 (IP:- 10.10.10.1/29 @ our end router) , 10.10.10.2 on Basestation wiresss device (Vlan 2 allowed on this wireless device) and this wireless device is working as point to multipoint wireless. i.e 2 or more then 2 wireless customers or last mile will connect to this basestation wireless.  Wireless customer-1 is 10.10.10.3 (2Mb bandwidth)  and Wireless Customer-2  10.10.10.4 (512Kb).


Hence we require to limit the bandwidth for this 2 wireless customers having different bandwidth. how to acheive & control bandwidth @ our end router for them. please suggest.



Thanks

This topic is probably better suited in another Infrastructure forum, but I suppose it depends on which features are supported by your Cisco hardware and software. This doc discusses a variety of options:

http://www.cisco.com/en/US/docs/ios/12_2/qos/configuration/guide/qcfpolsh.html


For example, with the older CAR (committed access rate) approach:


interface FastEthernet5/0
     ...
     rate-limit input access-group 101 20000000 [normal burst size] [excess burst size] conform-action transmit exceed-action drop

     rate-limit input access-group 102 5120000 [normal burst size] [excess burst size] conform-action transmit exceed-action drop


access-list 101 permit ip 10.10.10.3 0.0.0.0

access-list 102 permit ip 10.10.10.4 0.0.0.0


You can observe CAR in action with "show interfaces fa5/0 rate-limit" for example.
