Specifing max bandwidth usage for a protocol on a cisco 2600

We use 2621 router in our offices. Is there a way to limit the maximum amount of bandwidth a certain protocol uses. Like if I wanted to limit kazaa to let say 10Kb of bandwith maximum is it possible to do on a 2600 series router using 12.13T1 IOS. i know I can block the portocol all together with this latest IOS using :

ip cef

!

class-map match-any p2p

match protocol fasttrack

match protocol gnutella

match protocol napster

match protocol httpurl "\.hash=*"

match protocol httpurl "/.hash=*"

match protocol kazaa2

but how can I limit the maximum bandiwdth that P2P users can use?

thanks

Re: Specifing max bandwidth usage for a protocol on a cisco 2600

Let's do it this way. Lets enable NBAR on the ethernet interface connected to office LAN.

int e0

ip nbar protocol-discovery

Then we can go to create, class-map and policy-map and apply that to the interface. The bandwidth command in policy-map will limit the bandwidth which you want.

class-map kazaa

match protocol kazaa

policy-map limit-kazaa

class kazaa

bandwidth 10

int e0

service-policy input limit-kazaa

I am not sure if NBAR can detect KaZaa, if not, you can sue custom PDLM;-
