Tunnel forwarding centralizes wireless traffic processing on the WAC, which simplifies management but may cause traffic detours and increase WAC forwarding pressure. Direct forwarding improves forwarding efficiency because traffic is locally switched by APs, though roaming across edges can slightly affect roaming performance.

Radio information is related to wireless devices and APs, not wired devices. Telemetry-based metric collection for wired devices focuses on device, board, and interface information.

Network slicing creates multiple logical or virtual networks on shared physical infrastructure, not multiple physical networks. Each slice can have independent topology, SLA, reliability, and security characteristics to meet different service requirements.

DBS, DPA, and DCA are radio resource management technologies used to optimize wireless coverage, power adjustment, and channel allocation in WLAN environments. IPsec is a security protocol and not a radio resource management technology.

On iMaster NCE-Campus, VIP users are given prioritized network resources. Bandwidth can be reserved on APs for VIP users but is dynamically shared when they are offline. The system monitors their experience and generates alarms if performance degrades. In high-density scenarios like conference rooms, setting hosts as VIP users ensures consistent and high-quality wireless access.
