Which WLC interface is dedicated to management traffic?

• A. AP manager interface
• B. Virtual interface
• C. Service port interface
• D. Management interface

Answer: (D)

In Cisco WLCs, management traffic is carried on a dedicated management interface. This interface is reserved for the controller’s own management tasks—GUI/CLI access, SSH, SNMP, syslog, NTP, and other control-plane communications. Keeping these mgmt functions on a separate interface isolates them from user data and AP control traffic, improving security and reliability and ensuring you can reach the WLC for management even when data or AP traffic is busy. Other interfaces serve different roles: the AP Manager Interface handles CAPWAP control traffic between APs and the WLC; the Virtual Interface carries user data into the wired network; and the Service Port provides an out-of-band management path for direct access when needed. The management interface is the one specifically dedicated to the WLC’s management traffic.
