 If the administrator is unable to see interferers on the Cisco Prime Infrastructure maps, it could be due to the MSE (Mobility Services Engine) not being added and synchronized with Cisco Prime Infrastructure, which is essential for tracking and locating devices, including interferers. Additionally, if interferer tracking is not enabled on the MSE, it would not track or display the location of interferers on the maps. The other options, such as SNMP failure, reaching the Context Aware Service tracking limit, or inactive NSMP communication, would affect other aspects of network visibility but not specifically the tracking and display of interferers. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
