On a WLC, which interface is the default for in-band wireless management?

The wireless management interface is the default for in-band wireless management on a Wireless LAN Controller (WLC). This interface allows administrators to manage the WLC and access points through the wireless network itself, using a configured WLAN. Out-of-band management typically refers to a separate, dedicated management network, which isn't the default for wireless management. A redundant port is for high availability and failover, not a management interface type. The service port is primarily used for out-of-band management and initial WLC setup, not the default for in-band wireless management.
