Adding or Editing a Flow Source

 

Use the Flow Source window to add a flow source.

  1. On the navigation menu (), click Admin to open the admin tab.
  2. In the Data Sources section, under Flows, click Flow Sources.
  3. Do one of the following actions:
    • To add a flow source, click Add.

    • To edit a flow source, select the flow source and click Edit.

  4. To create this flow source from an existing flow source, select the Build from existing flow source check box, and select a flow source from the Use as Template list.
  5. Enter the name for the Flow Source Name.Tip

    If the external flow source is also a physical device, use the device name as the flow source name. If the flow source is not a physical device, use a recognizable name.

    For example, if you want to use IPFIX traffic, enter ipf1. If you want to use NetFlow traffic, enter nf1.

  6. Select a flow source from the Flow Source Type list and configure the properties.
    • If you select the Flowlog File option, ensure that you configure the location of the Flowlog file for the Source File Path parameter.

    • If you select the JFlow, Netflow, Packeteer FDR, or sFlow options in the Flow Source Type parameter, ensure that you configure an available port for the Monitoring Port parameter.

      The default port for the first NetFlow flow source that is configured in your network is 2055. For each additional NetFlow flow source, the default port number increments by 1. For example, the default NetFlow flow source for the second NetFlow flow source is 2056.

    • If you select the Napatech Interface option, enter the Flow Interface that you want to assign to the flow source.

      Note

      The Napatech Interface option is displayed only if you installed the Napatech Network Adapter on your system.

    • If you select the Network Interface option, for the Flow Interface, configure only one log source for each Ethernet interface.

      Note

      You cannot send different flow types to the same port.

  7. If traffic on your network is configured to take alternate paths for inbound and outbound traffic, select the Enable Asymmetric Flows check box.
  8. Click Save.
  9. On the Admin tab menu, click Deploy Changes.
