Cisco SD-AVC uses Cisco NBAR2 and other components that operate on devices in the network and operates at the network level, any application rule created by SD-AVC based on aggregated application data is shared and applied consistently across all participating network devices. 

Before we see the error message, let's login to the vManage console to see that error message

Below is the screen shot showing the error message when trying to create the custom applications, It seems like SD-AVC is disabled and we need to enable it first.

Resolution to the problem

Step 1: Login to the vManage and navigate to Administration > Cluster Management.
You will see that SD-AVC is disabled as this moment. Let’s enable it first.

Step 2: Activate the SD-AVC virtual image on the vManage, navigate to Administration > Cluster Management > … > Edit.  Once you clicked on the Edit button, you are asked for the username and password

Step 3: After enable SD-AVC it will prompt you a warning, a reboot is required. Click Ok and it will reboot the vManage.
