A network administrator just completed the basic implementation of Cisco CMX and tries to implement location tracking. The administrator is having trouble establishing connectivity between one of the WLCs through NMSP. What must be configured to establish this connectivity? (Choose two.)

To establish a connection between a Cisco Wireless LAN Controller (WLC) and a Cisco Connected Mobile Experiences (CMX) server, the Network Mobility Services Protocol (NMSP) is used. This requires two primary configuration steps. First, NMSP must be explicitly enabled on the WLC, and the CMX server must be added to the WLC's list of mobility service engines. Second, if a firewall or access control list exists between the WLC and the CMX server, it must be configured to permit NMSP traffic. NMSP uses TCP port 16113 for communication initiated from the WLC to the CMX server. Failure in either of these steps will prevent connectivity.

A. Add permanent licenses on the Cisco CMX server. Licensing enables specific CMX features and capacity but is not required to establish the initial NMSP network connectivity itself.
D. Reboot Cisco CMX after adding the WLC for the first time. Rebooting the CMX server is not a standard or required configuration step for adding a WLC and establishing an NMSP session.
E. Add to the WLC the MAC address and SSC key for the Cisco CMX server. The WLC is configured with the CMX server's IP address, not its MAC address. The SSC key is an outdated authentication method.

1. Cisco Connected Mobile Experiences (CMX) Configuration Guide, Release 10.6, "Setting Up and Configuring Cisco CMX" chapter, "Firewall Settings" section. This document explicitly states, "NMSP—TCP Port 16113 (Controller to CMX)." This validates that the firewall must permit this port.

2. Cisco Wireless Controller Configuration Guide, Release 8.10, "Mobility Services Engine" chapter, "Configuring Mobility Services Engines" section. This guide details the procedure for enabling NMSP on the controller: "Step 1: To enable NMSP on the controller, enter this command: config nmsp enable." This confirms that NMSP must be enabled on the WLC.

3. Cisco Connected Mobile Experiences (CMX) Configuration Guide, Release 10.6, "Adding Controllers to Cisco CMX" chapter, "Adding a Controller" section. The guide notes, "You must enable Network Mobility Services Protocol (NMSP) on the Cisco WLC to allow it to communicate with Cisco CMX." This reinforces the necessity of enabling NMSP on the WLC.
