Hi,

I have enabled the IP nbar protocol discovery on interface. user are able to access all the internet application but when seeing the sh ip nbar prptocol discover it showing blank.

Hi,

once you had enabled NBAR on the internet interface you need to use the following command:

"show ip nbar protocol-discovery stats bit-rate top-n 10"

You should see the top 10 protocols and http should be at the top.

ps: also make sure ip cef is enabled.

Router(config)#ip cef

Rate if this helps.

Thanks.
