This document provides information about the new show ap join stats commands in controller version
4.2.61.0 and demonstrates how to use them effectively. For more information, refer to Troubleshoot a
Lightweight Access Point Not Joining a Wireless LAN Controller to effectively troubleshoot why an access
point (AP) does not join a controller. Additional troubleshooting at the AP can be required if the AP does not
send a join to the controller.

This troubleshooting document applies to all the controller (WLC) versions from 4.2.61 to the latest version
of 7.2.103.

Several example outputs of different errors that occur on the controller follow the Background Information
and Troubleshooting Algorithm sections.
