Configuring Source Grouped Networks (C-Web Interface)
You can configure source networks in grouped format. For Junos OS ASP policy rules, you must enter source networks in grouped format.
To configure a grouped source network in a classify-traffic condition:
In the side pane, expand a traffic condition, expand Source Network, and select Group Network.
Click Create, enter information as described in the Help text in the main pane, and click Apply.
