My NBAR peer-to-peer config

[patsbc]

I built a config to rate shape P2P traffic on my network to 30k/s. I thought it would be useful for people who are looking to limit peer-peer traffic inside their company. If you have any additions or other ideas, let me know.

This is on a Cisco 1751 with IOS 12.3(4)T6. Later versions of 12.3 has newer PDLMs so you don't have to download them.

You will need to apply it to a interface by using the "service-policy output" command, also you need to have "ip nbar protocol-discovery" turned on the interface to get statistics.

Hi,

How do i apply this class-map to an interface?

If i have a few servers on the same vlan, can i apply it to the vlan instead of the individual switch ports?

Best Regards and thanks for any feedback.

Avoid NBAR, it's obsolete stuff without practical use.
