Which Wireless LAN Controller interface provides out-of-band management in Cisco's Unified Wireless architecture?

The service port on a Wireless LAN Controller (WLC) is specifically designed for out-of-band management. This means you can access and manage the WLC even if the network it controls is down or unreachable, providing a dedicated management path. The AP-Manager interface is used by the WLC to communicate with access points. A dynamic interface is a VLAN interface used to manage client traffic for specific WLANs. The virtual interface is a logical interface used for client redirection, DHCP proxy, and mobility management, not for direct out-of-band WLC management.
