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-source command 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-source command 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.
