Nbar not working

[a-craick]

I have a 7200 router with a single hssi interface and another fast ethernet interface. IOS 12.2(5).

I have enabled cef globably and didn't recieve any errors. I then tried to run a protcol discovery on the main hssi interface however after running a show ip nbar protocol-dicovery i can't see any packets recieved for any protocols.

Is there something I'm doing wrong.

Hello,

stupid question maybe but do you have ip nbar protocol-discovery enabled on the interface(s):

7200(config-if)#ip nbar protocol-discovery

yes i have tried enabled the protocol-discovery on both the main hssi interface 0/1 and also the subinterfaces however i don't get anything.

Can you tell us exactly what it shows when you type the command show ip nbar protocol-discovery?

[a-craick]

It displays the list of default protocols but with no traffic matched against any of the protocols (including unkown). i have confirmed that the sub interface and interface that we are applying the protocol discovery to does actuall have such traffic however its not being picked up by nbar.
