On a Cisco WLC, which interface is the default for in-band administration and controller–AP communication?

The management interface is the default and primary interface on a Cisco Wireless LAN Controller (WLC) for in-band administration (e.g., GUI, SSH, Telnet) and for communication with Lightweight Access Points (LAPs). It's assigned an IP address, subnet mask, and default gateway, and it's the source interface for all WLC-initiated communication with the network. The console port is used for out-of-band, direct serial access for initial configuration or troubleshooting, not for ongoing in-band administration or AP communication. The virtual interface is a special, unanchored interface used for mobility management, guest web authentication, and DHCP proxy, but it's not the primary interface for WLC-AP communication. The service port is an out-of-band management interface, typically used for direct WLC access in a separate management network, but it's not the default for AP communication.
