Can the Gateway Wireless Controller discover new or factory reset AP devices when VLAN Tagging is enabled?

The correct answer indicates that the Gateway Wireless Controller cannot discover new or factory reset access point (AP) devices when VLAN tagging is enabled. This is important to understand in the context of how VLAN tagging operates.

When VLAN tagging is applied, it separates network traffic into different virtual LANs, allowing for improved organization and security. Each VLAN operates as its own distinct network segment, which can complicate the communication between devices on different segments. In scenarios where a device is new or has been factory reset, it typically relies on specific discovery protocols to register itself with the controller. If the AP is isolated on a VLAN through tagging, it may not be able to reach the Gateway Wireless Controller, as they may be on separate subnets or network segments.

Thus, the lack of discovery capability in this situation stresses the importance of appropriate configuration. For the controller to discover the AP, they would need to be on the same VLAN, which reflects the nuances of networking and communication in VLAN-implemented environments.
