How to create a filter
You can choose what network traffic reaches your analysis tools. Use filters to ensure that only packets with certain characteristics are forwarded to tool ports.
To create a filter:
1. Starting in the dashboard, click Rules.
The rules and filters designer appears, where rules and filters can be created and edited.
2. Ensure the Filters tab is selected.
3. Click New.
The filter opens and is ready to edit.
4. Make your changes.
5. Click Save.
 
You successfully created a filter. The filter determines what packets are forwarded (or not forwarded) to tool ports and ultimately the devices connected to them.
 
 
For the filter to take effect, you must bind it to a rule and apply the rule in a layout.
