After configuring the authentication server and creating a dynamic interface for a new WLAN, what is the next step to complete the basic configuration?

After setting up the authentication server and creating a dynamic interface, the logical next step is to create the actual WLAN (Wireless Local Area Network) that users will connect to. This WLAN then needs to be associated, or "bound," to the dynamic interface you just created. The dynamic interface defines the VLAN and network parameters for the WLAN, so binding them together makes the WLAN functional. Configuring high availability and redundancy is an advanced step for network resilience, not a basic configuration. Enabling Telnet and RADIUS on the management interface relates to device access and security, not the WLAN itself. Installing the management interface and adding its IP address would typically be done much earlier, during the initial setup of the wireless LAN controller (WLC).
