After you complete the Closed Network setup on MySonicWall, you can go your NSM system to import the licenses.
Navigate to Manager View | HOME > Settings > Closed Network.
On the Import Signatures / Licenses tab, click Import.
Refer to Manager View | HOME > Settings > Closed Network and select the Device License tab to see the devices managed by this NSM system.
The devices listed in the Device License tab are the same that are listed in MSW for this instance of NSM.
