Get SNMP Traffic Totals

When certain flow sources export flow statistics for a portion or "sample" over overall traffic observed, you can complement flow sampling by gathering packet count totals using SNMP.

To add a device as an SNMP Source for traffic and packet totals:

  1. Open the NTA Sources Library (SETTINGS menu > Network Traffic Analysis > NTA Sources).
  2. Click Add > NBAR Polling Source.

    The Flow Source dialog displays.

  3. Enable data collection from this source. When you enable the current source will count as points against your Flow Monitor license.
  4. Provide the following field values:
    • Source IP Address. IP address of the flow source device.
    • Display Name. (Optional.) Name to display in source and NTA reports.
  5. Polling source.
    • NBAR. Click to enable NBAR classification data.
    • Poll source for total interface traffic. Click on this box to enable the device as an SNMP statistics source for Network Traffic Analysis.
  6. SNMP credentials. Select appropriate credentials from the drop down list.

    WhatsUp Gold Network Traffic Analysis queries the source device for interface information. The Interfaces frame displays known network interfaces for the current device.

  7. Access rights. (Optional) Opens the Flow Source access rights dialog that enables you to block WhatsUp Gold users from the flow data.
  8. Interfaces. Select one or more interfaces and click OK.

    Network Traffic Analysis saves your SNMP source which also displays in your NTA Sources Library.

  9. Check a report that reveals traffic totals for the network segment where there is no flow monitoring or where flow packets exported are only a sample (such as with Sflow-enabled devices).
