Zorluk: OrtaAP and WLC Management Access Connections

A network engineer is configuring network access for a newly installed Cisco Wireless LAN Controller (WLC) and Lightweight Access Points (APs). The WLC Management interface uses VLAN 10 to communicate with APs, while the Service Port is connected to a dedicated out-of-band management network. Which TWO statements accurately describe the operational requirements and characteristics of these management connections?

  1. The Service Port operates strictly out-of-band for administrative access and cannot terminate CAPWAP tunnels from APs.Cevap
  2. The switch port connected to the WLC Management interface must allow VLAN 10 traffic to pass CAPWAP control and data packets.Cevap
  3. C
    Spanning Tree PortFast should be enabled on standard trunk switchports connecting to the WLC to prevent CAPWAP tunnel flapping.
  4. D
    Lightweight APs in default Local mode use the Service Port to locally switch client data traffic if the CAPWAP tunnel drops.

Cevap

The Service Port provides out-of-band administrative management only and cannot terminate CAPWAP tunnels, while the switch port connected to the WLC Management interface must be configured to pass VLAN 10 traffic carrying CAPWAP control and data packets.
The correct options accurately identify the fundamental roles of Cisco WLC management access interfaces. The Service Port is dedicated to out-of-band administration and does not participate in CAPWAP data or control plane processing. The Management interface handles CAPWAP communication with APs, requiring the supporting switch interface to be configured with the appropriate VLAN access.

Adım Adım Çözüm

1
Analyze WLC Service Port functionality
Identify that the Service Port is isolated for out-of-band management and does not carry CAPWAP tunnel traffic from APs.
Out-of-band ports are non-routable in-band interfaces designed solely for administrative access to the WLC CLI/GUI.
2
Analyze WLC Management Interface requirements
Verify that the switchport trunking or VLAN settings must explicitly allow VLAN 10 so APs can establish CAPWAP tunnels to the WLC Management IP address.
The WLC Management interface handles in-band management and CAPWAP tunnel termination for Lightweight APs.
3
Evaluate distractor statements regarding STP PortFast and AP Local mode
Reject the statements advocating PortFast on trunk links and local switching by Local mode APs via the Service Port.
PortFast on standard trunks risks Layer 2 loops, and AP local switching requires FlexConnect mode, not default Local mode.
