Hi, my isp provider is limiting my server's traffic by port. but there are some data rsync in my local network. so i told them change into base on ip limited.

I read the document on cisco web site and  in

http://www.cisco.com/en/US/docs/switches/lan/catalyst2950/software/release/12.1_22_ea5/command/reference/2950CR.pdf

and it support class /  class-map and police police map command and also MLS QOS COS and the isp's switch infos are:

------------------------------------------------------------------------------

and here is my questions:

1、Can C2950-I6Q4L2-M support MLS QOS ?

2、I told the guy not using MLS QOS , Can just using Police and Class map to limited rate base on ip?

3、the isp guy said that this plamform(C 2950) not support MLS can not upate the ios to support it, is ture?

4、if it can upate ios to support MLS QOS ,which ios can do is?

thanks! sorry for the terrible english
