Troubleshooting CCXv5 Client Devices
The controller supports three features designed to help troubleshoot communication problems with
CCXv5 clients: diagnostic channel, client reporting, and roaming and real-time diagnostics. See the
“Configuring Cisco Client Extensions” section on page 6-35 for more information on CCX.
Note These features are supported only on CCXv5 clients. They are not supported for use with non-CCX
clients or with clients running an earlier version of CCX.
