Avaya WLAN Security Switch 2300 Series Troubleshooting and Debug Guide
Status of WSS and APs showing as blue (unknown) or is not accurately reported even though devices are
known to be up and operational.
Troubleshooting steps:
Check the Operating System logs to determine if the OS has been shutdown improperly. Most database
corruption issues in WSS Software 4.0.20+ can be attributed to improper shutdown.
Verify the system meets the minimum requirements for WMS. If you are running both the service and the
client on the same machine you must add the memory requirements together and use at least highest CPU
requirement.
If neither of the first two steps apply, copy the contents of the “services-db” and “logs” directory then
contact NETS for analysis.
Stop the WMS service as appropriate for your host operating system.
delete the <install-dir>\service-db directory
Start the WMS service as appropriate for your host operating system. WMS should now show correct status
for all equipment after the next polling cycle.
Troubleshooting auto-tune channel
Typical symptoms:
Intermittent client disconnects, frequent channel changes.
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.
Look for correlations between disconnect complaints and auto-tune channel events to verify that
disconnects are due to Auto-Tune Channel. Display filtered logs on the WSS using the following
command:
Show log buffer matching “Changing channel”
Messages will appear in the logs similar to:
