Exam 300-430 topic 1 question 196 discussion

C. Clean Air is enabled: Cisco CleanAir is a feature that detects and mitigates RF interference, including jamming devices. Enabling CleanAir ensures that the wireless network can detect such devices. D. Air Quality Index Trap is enabled: This feature sends SNMP traps when the air quality index (AQI) drops due to interference, such as from a jamming device. Enabling this ensures that alerts are raised when interference is detected. Why not the other options? A. Jammer is in the “Rogue Devices to Detect” multiple select box: This is not a specific configuration for detecting jamming devices. B. Jammer is selected in the Rogue Policies: Rogue policies are for detecting rogue access points, not jamming devices. E. Set the Cisco WLC to trap this type of device: This is not a specific configuration step for jamming devices. Thus, the two required parameters are Clean Air is enabled and Air Quality Index Trap is enabled.

E: if you want the Cisco WLC to send an alarm when it detects a jamming device, check the Enable Interference Type Trap check box and move the jamming device to the Trap on These Types box. C: Check the CleanAir check box to enable Cisco CleanAir functionality on the 802.11a/n or 802.11b/g/n network, or uncheck it to prevent the Cisco WLC from detecting spectrum interference. By default, this feature is in disabled state. -Air Quality Enable by default

I believe Rogue Detection only works with-in 802.11 standards, so it would not be able to detect raw RF interference. Thus you are looking at Clean Air and some sort of trapping method to alert.

CleanAir is required as that enables the AP chipset to detect interference. Then in 9800 you go to Configuration --> Radio Configurations --> CleanAir --> Select Trap Configuration --> Move Jammer to the Interference Types to trap box.
