Overview

This article provides steps to resolve the following error:

NTA has received flow data from an unmanaged Interface

 

When NTA receives data flow from an unmanageable interface, it displays an event in NTA Traffic Analyzer pane.

This interface does not support SNMP, you can "register" it to NPM, and thus enable the NetFlow Receiver Service to process the flow data it exports to NTA. If the interface is not in NPM, NTA will drop the data flow.

Environment

All NTA versions

Resolution

To add the unmanageable interface:

  1. Click Add this interface in the unmanaged event. The following dialog displays, with the interface name in the Interface Name field.
  2. Define the Interface Speed
    1. Refer to your device administration documentation for the correct interface speed, and enter it into the appropriate field.
    2. Select the speed type from the pull-down menu.
  3. Click SUBMIT. The interface has been added to NPM and can be viewed in NPM’s Node Management page.
