Working with Interfaces and Routers › Available Interfaces Page › Enable or Disable Interfaces

Enable or Disable Interfaces

Interfaces are enabled automatically on the Application Settings page by default. You may want to enable interfaces manually in some cases, such as in the following example scenarios:

• Interfaces have been disabled temporarily and you want to re-enable them.
• The program is not configured to enable newly discovered interfaces automatically. (The Auto-Enable Interfaces option is set to False in the Application Settings page.)

Enabling an interface causes the following events to occur immediately:

• The interface can be used as a filter in Flow Forensics reports.

  The data that is available in Flow Forensics reports includes data that was collected while the interface was disabled.

• Other types of interface data begin to be collected and stored, such as data for hosts, conversations, ToS, and protocols. Once the initial period of data collection is complete, the additional interface data can be displayed in drilldown interface reports, Analysis reports, and Custom reports.

Follow these steps:

1. Open the Available Interfaces page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select System: Enable Interfaces in the Administration menu.

      The Available Interfaces page opens.

2. Click the arrow next to the router that contains the interfaces.

   The view expands to show the interface list. The Enabled status column shows which interfaces are enabled.

3. Select the check box next to one or more interfaces.
4. Click one of the following options:
   • Enable (enable data collection for the interface)
   • Disable (prevent the collection of data for the interface)

   Data collection for the selected interfaces is enabled or disabled immediately.
