Information About Wireless Management Interface
The Wireless Management Interface (WMI) is the mandatory Layer 3 interface on the Cisco Catalyst 9800 Wireless Controller. It is used for all communications between the controller and access points. Also, it is used for all CAPWAP or inter-controller mobility messaging and tunneling traffic.
WMI is also the default interface for in-band management and connectivity to enterprise services, such as, AAA, syslog, SNMP, and so on. You can use the WMI IP address to remotely connect to the device using SSH or Telnet (or) access the Graphical User Interface (GUI) using HTTP or HTTPs by entering the wireless management interface IP address of the controller in the address field of your browser.

Layer 3 interface is not supported in Cisco Catalyst 9800-CL Cloud Wireless Controller Guest anchor scenarios. Instead, it is recommended to use the Layer 2 interfaces and SVI for WMI. It is recommended to use Layer 3 interface for Public cloud deployments only and not for on-premise as it poses some limitations. The following are the sample Layer 3 and Layer 2 interface configurations: Layer 3 interface configuration:
