Difficulty: HardAP and WLC Management Access Connections

An enterprise network infrastructure utilizes a Cisco centralized wireless architecture. A network engineer is connecting a Lightweight Access Point (AP) operating in Local mode to an access switch and configuring the Wireless LAN Controller (WLC) Management Interface on a distribution switch trunk. Which TWO statements accurately describe the switchport configuration and interface connectivity requirements for this deployment?

  1. The access switch port connected to the Local mode AP should be configured as an access port assigned to the AP management VLAN.Answer
  2. The WLC Management Interface handles in-band CAPWAP tunnel management and control traffic between the AP and WLC as well as controller GUI/CLI administrative access.Answer
  3. C
    The access switch port connected to the Local mode AP must be configured as an 802.1Q trunk port with tagged VLANs for each client WLAN SSID.
  4. D
    The switch trunk port connected to the WLC Management Interface must be configured with a native VLAN ID that differs from the controller management VLAN to enforce untagged out-of-band management isolation.

Answer

The correct statements are: (1) The access switch port connected to the Local mode AP should be configured as an access port assigned to the AP management VLAN, and (2) The WLC Management Interface handles in-band CAPWAP tunnel management and control traffic between the AP and WLC as well as controller GUI/CLI administrative access.
In a Cisco centralized deployment, Local mode APs send all control and data traffic through CAPWAP tunnels to the controller. Consequently, the access layer switchport connecting to a Local mode AP needs only to be an access port in the AP management VLAN. Additionally, the WLC Management Interface serves as the primary in-band interface, handling both CAPWAP tunnel termination from APs and administrative management traffic (GUI/CLI).

Step-by-Step Solution

1
Analyze AP deployment mode requirements (Local mode vs. FlexConnect mode).
In Cisco centralized architecture, a Local mode AP encapsulates all client wireless frames inside IP/CAPWAP tunnel packets sent to the WLC. The AP requires only a single IP address on the management network.
Since client traffic is tunneled over L3 CAPWAP, the switch port facing a Local mode AP does not need 802.1Q trunking or multi-VLAN configuration; a standard access port on the AP management VLAN is sufficient.
2
Evaluate WLC logical interface functionality (Management Interface vs. Service Port).
The WLC Management Interface is an in-band, routed logical interface that terminates CAPWAP tunnels from APs and supports HTTP/HTTPS/SSH administrative access.
Out-of-band management uses the dedicated physical Service Port, whereas the Management Interface handles both AP CAPWAP management/control and in-band management traffic.
3
Identify misconfigurations regarding VLAN trunking and native VLAN settings.
Configuring trunk ports for Local mode APs confuses Local mode with FlexConnect local switching, and mismatching native VLAN settings breaks 802.1Q trunk operation.
FlexConnect mode requires trunking for local VLAN mapping. Mismatching native VLANs generates STP/CDP errors and disrupts reachability.
