In the Edit Policies view ( (Configure) > Capture Policies > Edit, administrators can configure selective network data collection policies. The panels for creating a new policy and editing an existing policy are the same except that in the editing wizard, the definitions of the existing policy are displayed.
You can edit existing policies to customize them for your environment. A base set of protocols are available for alterations, allowing you to choose what level of capture you prefer on a per-protocol basis. If you are only making slight changes, a good start for customization is to clone one of the predefined polices and alter it.
The following figure shows the workflow for common Decoder configuration tasks with the steps you can complete in this view highlighted.
