Performing Advanced Administration › Work with Interfaces › Enable Interfaces

Enable Interfaces

Interfaces are enabled automatically in CA Network Flow Analysis by default. You enable interfaces manually, however, in the following situations:

• Interfaces have been disabled temporarily and you want to re-enable them.
• The program has been configured so it does not 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 number of Harvester licenses in use increases by one.
• Flow Forensics data for the interface is available in Flow Forensics reports. The Flow Forensics data that you can view includes data that is 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 prototypes. 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 in the Administration menu.

      The Available Interfaces page opens.

2. Click the arrow on the left edge of the row for the router that contains the interfaces that you want to enable.

   The view expands to show a list of the interfaces for the selected router. The information that is displayed includes Enabled status and License status.

3. Select the check box next to one or more interfaces.
4. Click Enable.

   The selected interfaces are enabled immediately.
