Troubleshooting Auto-Tune Power - Avaya WLAN Security Switch 2300 Series Troubleshooting And Debug Manual

Each of these messages will indicate the reason for the change, and you can try to correlate the DAP and
timedate stamp with user complaints. Collect the entire log (unfiltered) for analysis. If the system is
continually changing channels it has not converged for some reason, and the logs will assist in determining
this.
Collect the output of "show auto-tune neighbors"
This command displays all of the neighbors seen by each radio. This will give you an idea of how many other
APs are visible from each radio and what their signal strength is.
Turn on autorf tracing level 10 and capture the output over an extended time period.
This will display more detailed information on what the radio sees and why it changes it is channels, and this
will provide additional debugging information to assist Engineering in determining why the system is
changing channels.
Disable auto-tune channel
If the disconnects are too disruptive for the customer, use the "Apply Auto-Tune Settings" option under the
"Manage" menu in WMS to convert the dynamic settings to static configuration and disable the auto-tune
feature.
As of WSS Software version 4.0.21, the auto-tune algorithm still does not take into consideration client
connectivity when it decides to change channels. Most customers value connectivity more than dynamic
adaption of channels, so Auto-Tune channel should be used to set the initial channel set and then it should be
converted to a static configuration by using the WMS "Apply Auto-Tune Settings" option under the "Manage"
menu.
Modifications to the Auto-tune channel feature are in progress, and the first set should be implemented in the
MSS 4.0.22 maintenance release in early March.

Troubleshooting auto-tune power

Typical symptoms:
APs appear not to be tuning power; client signal strength appears to vary widely and rapidly.
Troubleshooting steps:
Verify that active-scan is enabled
Auto-tune channel depends on active-scan to build the neighbor lists. If active-scan is disabled, auto-tune
channel must also be disabled. This will typically occur in VoIP environments where the handset providers
typically require auto-tune to be disabled anyway.
Set the syslog severity to "Notice" to show auto-tune operations
