Multiple Netflow v9 Sensors



I have several switches and I added a netflow v9 sensor to each. However when I view the data for the sensor they all return information for the first netflow v9 sensor I created on switch 1. Is there a special way to add a netflow sensor so it uses the data for that device?

do you use a different port for each Netflow Sensors? If not, please do so, because the sensors can't differ between Netflow packets from different sources.

Best Regards.

Ah yes, that makes sence. I'll use different ports for each Netflow sensor.
