Zorluk: OrtaAP and WLC Management Access Connections

A network administrator is setting up out-of-band administrative access for a newly deployed Cisco Wireless LAN Controller (WLC). The design requires isolating administrative management traffic (GUI/SSH) from AP CAPWAP tunnels and user data traffic by utilizing the dedicated physical Service Port on the WLC. Which operational characteristic correctly describes the behavior and network configuration of the WLC Service Port?

  1. It operates strictly out-of-band and uses an independent routing configuration separate from the WLC data plane dynamic and management interfaces.Cevap
  2. B
    It requires 802.1Q trunking with a specific native VLAN tag to carry CAPWAP control packets from lightweight APs.
  3. C
    It must be configured on the connected switch port with Spanning Tree PortFast trunk mode to forward in-band management traffic across L2 switches.
  4. D
    It automatically acts as the primary CAPWAP tunnel termination point for lightweight APs operating in FlexConnect mode.

Cevap

The WLC Service Port operates strictly out-of-band and uses an independent routing configuration separate from the WLC data plane dynamic and management interfaces.
The correct answer highlights that the Cisco WLC Service Port is a dedicated out-of-band management interface. It is physically separate from the distribution system ports, operates in its own routing domain, and is reserved for administrative GUI/SSH management, system recovery, and maintenance without handling CAPWAP or client data traffic.

Adım Adım Çözüm

1
Identify the primary functional role of the Cisco WLC Service Port.
The Service Port is a dedicated 10/100/1000 Ethernet interface designed for out-of-band management, system recovery, and initial setup.
Out-of-band management separates administrative control plane traffic from data plane and wireless infrastructure traffic.
2
Evaluate how traffic routing and connectivity differ between the Service Port and in-band interfaces (Management/Dynamic).
The Service Port maintains its own static routing gateway configuration and does not pass CAPWAP, client data, or dynamic interface traffic.
This physical and logical isolation ensures management access remains functional even during heavy data plane saturation or network outages.
