How do I set a NetFlow sampling rate?

Follow

The sampling rate is indicated in a header field of NetFlow version 5 (same sampling rate for all interfaces) or in option records of NetFlow version 9 (sampling rate per interface). The sampling rate is configured on the device.  Click here for our NetFlow sampling rate recommendations.

Please keep in mind that if you configure the sampling rate from your Auvik dashboard, it must also be configured on the device itself because the configuration on the device is what is used.

The following must be completed from the client dashboard.
