This writeup by Jake Snyder explains how to put an autonomous Cisco AP in SE-Connect mode for spectrum analysis with Chanalyzer 5 + Cisco CleanAir Accessory.

The process is performed through the Cisco IOS command line.

Put an Autonomous Cisco AP into SE-Connect Mode

To view spectrum analysis data, the Cisco CleanAir AP needs to be placed into SE-Connect (Spectrum Expert Connect) mode. To put the AP into SE-Connect mode, run these commands:

conf t int dot11radio X
no mbssidx
station-role spectrum
exit
exit

Find the Cisco AP NSI Key

Chanalyzer requires an IP address and an NSI key to connect to the Cisco CleanAir AP. To find the NSI key, run this command, and view the output:
