Check the Agent Logs
Verify the Firmware on the Controller
The firmware on the controller must be of at least version 6.0 for official support of the AP as a sensor. One
symptom that the firmware is not compliant is that the log for the Agent will fill with Array Index out of
Bounds errors, or messages that the AP is reporting an illegal or unknown channel.
Verify the Snoop Configuration
On the controller, use the command show snoop stat to verify that the APs are supposed to act as sensors and
that they are reporting data.
Also check the snoop map to make sure that the listener IP address matches the IP address for the WLE2340,
and that the APs and radios that are acting as sensors are using this snoop map. The
show snoop info
command can help to get this information.
Finally, verify that the snoop mode is enabled for the APs and radios that should be acting as sensors.
Check the Auto Discovery in the WLE2340
Browse in the standard Web UI to the menu item Configuration > Sensors . Verify that the APs acting in
snoop mode have been discovered and that they are listed with the correct IP address. If they are not, then
disable them. Disable snoop mode from the controller. Then re-enable snoop mode.
Check the Sensor Statistics
You can look at statistics for the sensors with the show sensors command, from the command line interface.
This gives the name, IP address, status (operational, a Boolean field), the number of devices tracked by the
sensor and a packet count. The packet count should be raised for all active sensors that are reporting monitored
wireless traffic. If the devices are not operational or the packet count is static, it is likely that the APs are not in
snoop mode, or somehow unable to communicate with the WLE2340.
Firewall Settings
The APs acting in snoop mode sends TZSP formatted information through UDP on port 37008 to the
WLE2340. If there is a firewall or VLAN configuration with port restrictions between the sensor APs and the
WLE2340, this traffic may be blocked. Verify that the communication is clear between the two.
Check the Agent Logs
Problems with AP Communication are logged in the Agent log. Check those logs for problems that may not be
discussed here.
Tracking
This covers questions related to the accuracy and latency of the tracking information provided by the
WLE2340.
Examples
"Why are certain devices tracking differently when in the same place?"
