These instructions assume:

  • You’re running Firepower Management Center (FMC) software version 6.2 or higher.
  • Firepower Threat Defence (FTD) devices are connected to your FMC device.
  • The date, time and time zone are correctly set on the Firepower devices.

  • The IP address of your Auvik collector is known.

Set the Auvik collector parameters

  1. Navigate to Objects
  2. Click on Objects Management
  3. Click on FlexConfig
  4. Click on Text Object
  5. Edit the netflow_Destination object

  6. In this variable, set the interface sending Netflow, the Auvik collector IP address, and the port

Note: You need to change the count to 3, it is 1 by default.

Create the FlexConfig Policy

  1. Navigate to Device
  2. Click on FlexConfig
  3. Click on New Policy
  4. Give a name to the policy
  5. Select the Firewall(s) to receive the policy

You may see a message in TrafficInsights informing you that no templates are being sent from the device. Do not troubleshoot it right away. Wait for about 30 to 60 minutes and check it again.
