300-430 Question #205: Real Exam Question with Answer & Explanation
The correct answer is B: Allow on the firewall port 16113 between Cisco CMX and the WLC.. NMSP connectivity between Cisco CMX and a WLC requires that TCP port 16113 is permitted through the firewall and that NMSP is explicitly enabled on the WLC.
Question
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.)
Options
- AAdd permanent licenses on the Cisco CMX server.
- BAllow on the firewall port 16113 between Cisco CMX and the WLC.
- CEnable NMSP on the WLC.
- DReboot Cisco CMX after adding the WLC for the first time.
- EAdd to the WLC the MAC address and SSC key for the Cisco CMX server.
Explanation
NMSP connectivity between Cisco CMX and a WLC requires that TCP port 16113 is permitted through the firewall and that NMSP is explicitly enabled on the WLC.
Common mistakes.
- A. Permanent licenses on the CMX server govern feature entitlement and device capacity but have no bearing on whether the NMSP transport-layer session can be established between CMX and the WLC.
- D. Rebooting CMX after adding a WLC is not required; the NMSP connection is negotiated dynamically once the correct port access and WLC configuration are in place.
- E. Providing the CMX server MAC address and SSC key on the WLC is not a standard requirement for NMSP connectivity in current CMX deployments; WLC-CMX trust is established through IP address and shared secret configuration, not MAC or SSC entries.
Concept tested. CMX NMSP connectivity - required port and WLC configuration
