DESCRIPTION
Nebula Discovery
Slide the switch to the right to enable Nebula Discovery to have the Zyxel Device try to connect to the NCC. Once the Zyxel Device is connected to and has registered in the NCC, it’ll go into the Nebula cloud management mode.
If Nebula Discovery is disabled, the Zyxel Device will not discover the NCC and remain in standalone operation.
This is not configurable and will only display ON when your Zyxel Device is being managed by NCC. See Network Setting > Nebula (with registration in the Nebula Control Center).
