C9200: Configuration Application Visibility/AVC/Nbar for Vlan Interface.

Hi Guys,

I am trying to configure Application Visibility for a Vlan interface on my C9200L. As soon as the desired VLAN is added in the CLI / Webui, the error message "NBAR Error: Can not enable Protocol-discovery general error" appears.

 

Any ideas? (The Ethernet ports can be added easily.)

LG,

PGI

Hi,

 

   Have you tried from the CLI via "ip nbar protocol-discovery" ? Ensure you have logging on to spot any error messages.

 

Regards,

Cristian Matei.

Hi,
Yes, get the same error:
Catalyst(config-if)#ip nbar protocol-discovery
%% NBAR Error: Can not enable Protocol-discovery general error
Catalyst(config-if)#

Hi,

 

   What is the interface configuration on which you're trying to enable NBAR? Can you post it? Also do you see any output on NBAR commands, like "show ip nbar attribute"?

 

Regards,

Cristian Matei.

Re: C9200: Configuration Application Visibility/AVC/Nbar for Vlan Interface.

What is the version of Code running by the Cat 9200 ?

 

Look at the configuration guide and pre-requisites before enabling NBAR

Cisco IOS XE Software, Version 17.01.01

I configured it according to this "book".
