Viewing the usage of a firewall common zone

You can see which firewall templates, CPE templates, and devices are using a previously created common zone. If at least one component uses the common firewall zone, such a zone cannot be deleted.

To view the usage of a common firewall zone:

1. In the menu, go to the SD-WAN → Firewall zones section.

   A table of firewall zones is displayed.

2. Click the common firewall zone whose usage you want to view.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon .

3. In the upper part of the settings area, under Actions, click Show usage.

This opens a window with a table of firewall templates, CPE templates, and devices that are using the common zone.
