A network administrator is organizing interface roles on a standalone Cisco Wireless LAN Controller (WLC) to support enterprise network access operations. Match each WLC logical or physical interface type on the left with its primary operational function on the right.
- Service PortDedicated out-of-band management connection used exclusively for system recovery, maintenance, and initial controller configuration.
- Management InterfaceDefault in-band interface used for CAPWAP management tunnel termination between APs and WLC, as well as administrative GUI/SSH access.
- Virtual InterfaceInternal logical interface used to handle Layer 3 Web Authentication, DHCP relaying, and inter-controller mobility management messaging.
- Dynamic InterfaceUser-defined logical interface associated with a specific WLAN and mapped to a VLAN for transporting wireless client data traffic.
Cevap
Service Port matches the out-of-band management connection; Management Interface matches in-band CAPWAP termination and administrative access; Virtual Interface matches internal web authentication and mobility services; Dynamic Interface matches WLAN-to-VLAN client data traffic mapping.
Each WLC interface fulfills a specific role in Cisco unified wireless architecture: the Service Port handles out-of-band management; the Management Interface processes in-band CAPWAP tunnels and admin access; the Virtual Interface manages internal features like WebAuth and DHCP proxying; and Dynamic Interfaces handle user data traffic segmentation on trunked VLANs.
