Enabling Auto-Creation of NetFlow Data Sources Using the CLI

Configuration of the auto-create feature is also possible using the NAM CLI. Remember that the auto-create feature is turned ON by default, so in most cases these steps are not necessary.

To configure the NAM to automatically create data sources when it receives NDE packets from an external device, use the following steps:

Use the autocreate-data-sourcecommand as follows:

root@172-20-104-107.cisco.com# autocreate-data-source netflow NDE data source autocreate successfully ENABLED

The NAM will now automatically create a NetFlow data source for each device that sends NetFlow packets to it. The data source will have the specific Engine ID that is populated by the device in the NDE packets sent to the NAM. If the same device happens to send NDE packets to the NAM with different Engine ID values, a separate data source will be created for each unique Engine ID sent from the device.

Disabling Auto-Creation of NetFlow Data Sources Using the Web GUI

Step 1 Click Setup > Traffic > NAM Data Sources.

Step 2 Click the Auto Create button on the bottom left of the window.

Step 3 Uncheck the Netflow check box to toggle auto-creation of NDE data sources off.

Step 4 Click the Submit button.

Disabling Auto-Creation of NetFlow Data Sources Using the CLI

To disable auto-creation of NetFlow data sources, use the no autocreate-data-sourcecommand as follows:

root@172-20-104-107.cisco.com# no autocreate-data-source netflow NDE data source autocreate successfully DISABLED root@172-20-104-107.cisco.com#

Creating NetFlow Data Sources Using the Web GUI

To manually configure a NetFlow data source on the NAM using the GUI, for example if the auto-creation feature is turned OFF, use the following steps:

Step 1 Click Setup > Traffic > NAM Data Sources.

Step 2 Click the Create button along the bottom of the window.

Step 3 In the Type drop-down list, select “NetFlow.”

Step 4 Enter the IP address of the device that will export NDE to the NAM (required).

Step 5 Give the Data Source a name. This name will appear anywhere there's a Data Source drop-down list.
