Difficulty: MediumAP and WLC Management Access Connections

Match each Cisco AP and Wireless LAN Controller (WLC) connection type to its corresponding switchport configuration requirement.

  • Cisco AP operating in Local ModeAccess port assigned to the dedicated AP management VLAN
  • Cisco AP operating in FlexConnect Mode with local switching802.1Q trunk port carrying tagged VLANs for local client traffic and a native VLAN for AP management
  • Cisco WLC Management Interface physical connection802.1Q trunk port carrying tagged traffic for dynamic interfaces and controller management
  • Cisco WLC Service Port physical connectionAccess port isolated for out-of-band controller administration without 802.1Q VLAN tagging

Answer

Local Mode AP matches Access port assigned to the dedicated AP management VLAN; FlexConnect Mode AP matches 802.1Q trunk port carrying tagged VLANs for local client traffic and a native VLAN for AP management; WLC Management Interface matches 802.1Q trunk port carrying tagged traffic for dynamic interfaces and controller management; WLC Service Port matches Access port isolated for out-of-band controller administration without 802.1Q VLAN tagging.
Each connection type matches its mandatory physical switch port requirement based on whether the link supports single VLAN access, 802.1Q trunking, or isolated out-of-band management.

Step-by-Step Solution

1
Analyze AP traffic modes to determine switchport configuration requirements.
Local mode APs send all client traffic inside CAPWAP tunnels to the WLC, requiring only a single-VLAN access port. FlexConnect APs with local switching forward client frames locally, requiring an 802.1Q trunk port with a native VLAN for CAPWAP management.
Understanding AP deployment modes determines whether single-VLAN access or multi-VLAN trunking is required at the access layer switch.
2
Analyze WLC interface physical connection requirements.
The main WLC distribution system port connects to an 802.1Q trunk port to multiplex controller management and dynamic VLANs. The physical service port connects to an access port dedicated to out-of-band management.
Controller architecture separates in-band multi-VLAN trunking from out-of-band isolated access management.
