Solarwinds & Cisco Live! Barcelona
Join us from the 29th of January to the 2nd of February at Cisco Live 2018 in Barcelona, where we will continue to show how monitoring the network with SolarWinds will keep you ahead of the game. At our booth (WEP 1A), we will demonstrate how SolarWinds network solutions can help. As a bonus, we are also hosting a pre-event webinar - Blame the Network, Hybrid IT Edition with our SolarWinds Head Geek™, Patrick Hubbard on January 24th - GMT (UTC+0): 10:00 a.m. to 11:00 a.m. There's still time to RSVP.

Set up a NetFlow collection

If you see a network device in your NetFlow Sources and you do not intend to collect NetFlow data from it, you can eliminate unnecessary traffic by turning off the export of data at the device.

  1. Configure your network devices to export NetFlow data for each interface for which you want to collect the data. For more information, see Device Configuration Examples.

    For information on enabling NetFlow for Cisco Catalyst switches, see the SolarWinds technical reference Enabling NetFlow and NetFlow Data Export (NDE) on Cisco Catalyst Switches.

    For information on enabling NetFlow on Cisco ASA devices, see the SolarWinds technical reference Understanding Cisco ASA NetFlow.

    If your network device is of a different vendor, see the documentation of the vendor.

  2. Verify that each interface for which you want to collect and view data is actively being monitored in SolarWinds NPM.

    For any interface that you need to add to SolarWinds NPM, see Network Discovery Using the Network Sonar Wizard.

    Use a packet capture tool, such as WireShark, on the relevant interface and port to verify that the device is hexporting data as expected.
