The Zyxel Nebula switches can automatically download the current configuration to new devices connected to the network to enable auto-provisioning without the need for on-site network professionals. All the Zyxel Nebula switches are centrally managed with a single management interface; switch settings made in the Nebula Control Center can automatically propagate to all connected Zyxel Nebula switches. The Zyxel Nebula Switches provide stable network environments by incorporating a mechanism that detects and prevents configuration that could potentially cause network disconnection between the device and Nebula Control Center. To provide stable connections, the Zyxel Nebula switches offer a smarter way for optimizing quality of service, which enables administrators to assign a priority to a specific VLAN through Nebula Control Center, and this priority can be applied to all tagged traffics for a specific VLAN. The Zyxel Nebula Switches can automatically discover wired and wireless devices that connected to a network, and then draw the network topology to enable network administrators to easily troubleshoot issues remotely.
