Question
A network engineer is configuring a Cisco AireOS 8.2 WLC, Cisco MSE, and Cisco PI with Cisco 3700 Series APs and Cisco Hyperlocation modules. The engineer configures and enables a WLAN with Hyperlocation. During testing, the engineer notices that location accuracy is poor. Which action resolves the issue?
A. Enable DCA in the Global Configuration settings of the WLC.
B. Install WLC software that supports the Hyperlocation module.
C. Use the same NTP server for syncing the time on the WLC, MSE, and PI.
D. Open SNMP port 161 and NMSP port 16113 on the controller.
Answer
C. Use the same NTP server for syncing the time on the WLC, MSE, and PI.
Explanation
When configuring Cisco Hyperlocation, it is crucial to synchronize the time across all components, including the Wireless LAN Controller (WLC), Mobility Services Engine (MSE), and Prime Infrastructure (PI). Poor location accuracy can result from time synchronization issues between these devices.
To resolve this problem, configure the WLC, MSE, and PI to use the same Network Time Protocol (NTP) server. NTP ensures that all devices operate with the same time reference, enabling precise coordination and data correlation for accurate location services.
By synchronizing the time using a common NTP server, the Hyperlocation system can accurately process and analyze location data from the access points and Hyperlocation modules, resulting in improved location accuracy and overall system performance.
