Zorluk: KolayAP and WLC Management Access Connections

A network engineer is deploying a Cisco Lightweight Access Point (AP) operating in Local mode. The AP needs to establish a CAPWAP tunnel back to the central Wireless LAN Controller (WLC). Which switch port configuration is required for the access switch interface connected directly to this AP?

  1. An access port assigned to the untagged VLAN used for AP management traffic.Cevap
  2. B
    An 802.1Q trunk port tagged for all user VLANs, expecting the AP to locally switch client data frames.
  3. C
    An 802.1Q trunk port configured with mismatched native VLAN settings on opposing ends of the AP link.
  4. D
    A switch-to-switch trunk port configured with PortFast enabled to instantly bridge inter-switch traffic.

Cevap

An access port assigned to the untagged VLAN used for AP management traffic.
In Local mode, a Cisco Lightweight AP encapsulates all client traffic inside a CAPWAP tunnel sent back to the WLC. Because individual WLAN client VLANs are managed centrally at the controller, the switch port connected to the AP only needs to transmit untagged management traffic. Therefore, configuring the port as an access port in the AP's management VLAN is the correct method.

Adım Adım Çözüm

1
Identify the operational mode of the Access Point.
The AP is operating in Local mode.
Local mode APs tunnel all user traffic and management frames directly to the Wireless LAN Controller via CAPWAP.
2
Determine the network access requirement for Local mode AP traffic.
The AP only requires Layer 3 IP reachability to the WLC's management IP address.
Because client VLAN traffic is not locally bridged by the AP, user VLANs do not need to be trunked to the AP.
3
Select the appropriate switch port configuration.
Configure the switch port as a standard Layer 2 access port in the AP management VLAN.
An access port provides the untagged connectivity necessary for the AP to receive an IP address and reach the controller.
