Issues Corrected in this Release

· Calibration Model (CSCar14794) - Applying a calibration model from the Cisco WCS RF Calibration Model > <Particular Model> > Apply to Floors now pushes the information to the location appliance.

· Cisco WCS (CSCar15013) - Exceptions occurred when all the information had not yet been collected from the Cisco WLAN Solution.

· SNMP V3 Parameters (CSCar15208) - Operators can now use the non-default SNMP V3
parameters to support Cisco Wireless LAN Controller-to-location appliance communications.

· Short Polling Interval Failures (CSCar15390) - When a location appliance has collected data from a tracked RFID tag, client, or rogue but was unable to obtain accurate RSSI values, the location appliance acknowledges the presence of the Tag, client, or Rogue, but not its location. The workaround is to wait for the location appliance to collect the required RSSI values during another polling cycle.

Technical Notes

· To push a Cisco WCS Calibration model to the location appliance, edit the Floor Area to change the model or go to the model and apply to Floor Areas, and then synchronize the change to the location appliance.

· The Cisco WCS Maps refresh at the rate of your network connection speed. For instance, if you are dialing in across a 52-Kbps line, Maps refresh slowly.

· Location Appliance (CSCsa96296) - Collected events are batch committed to the location appliance database and appear on Cisco WCS only after two minutes. This means that an event can appear in the location appliance logs but not in Cisco WCS under Location Servers > Server Events. This is expected operation.

· Clients Summary page contents (CSCsa96318) - When Cisco WCS has a location appliance associated with it, the Cisco WCS Clients Summary page shows the following:

- A Clients chart on the right side of the page, which show the number of associated Cisco WLAN Solution clients over time.

- A Clients Detected by Location Appliance list, which show the number of clients detected by each location appliance over the last 15 minutes.

· Location Appliance Network Unreachable (CSCsa98854) - When the location appliance reports that the network to Cisco WCS is unreachable, please check the following to ensure that the network is up and reachable:

- Netmask of the location appliance and Cisco WCS.

- Gateway on the location appliance and Cisco WCS.

- Route between the location appliance and Cisco Wireless LAN Controller.

· Administer Logging page settings (CSCsa98980) - Cisco recommended that network operators do not leave the logging level set to TRACE on the location appliance for long periods of time. Setting the log level to TRACE adversely affects the location appliance performance. Setting the log level to TRACE should only be performed when recommended by a technical support engineer or other Cisco personnel.

· Location Appliance database (CSCsb01637) - When the location appliance is performing various tasks, such as rebooting or defragmenting, it protects the database from corruption by blocking reads and writes. While the location appliance is performing these tasks, Cisco WCS may display `Location Appliance Unreachable' messages. This is expected operation.

· The location appliance default speed and port configuration is 100BASE-Tx-FD. To verify the current speed and port configuration, use the following command:

> /sbin/mii-tool
eth0: negotiated 100baseTx-FD flow-control, link ok
eth1: negotiated 100baseTx-FD, link ok

To have the location appliance autonegotiate for any other speed or configuration, use the following command:

> mii-tool -r

Open Issues in Cisco 2700 Series Location Appliances

· Location Accuracy (CSCar14829) - Because of the method used to calculate RSSI samples for the location appliance, we have observed instances in which the RSSI samples do not show some clients' actual locations. This is related to how clients probe or do not probe, and the validity of the RSSI sample. We know of an Atheros-based bug where it is possible to receive uncalibrated packets.

· Location Appliance (CSCsa98851) - In the rare occurrence that a location appliance fails to respond to any commands but remains powered up, Cisco WCS may not report any error messages. The workaround is to reboot the location appliance from the location appliance CLI interface. Execute the command reboot -h now from a command line prompt.

· Location Server (CSCsb04624) - On some occassions, adding a WCS with deny access to an existing location server session will not terminate the existing session.

· Location Server (CSCsb15455) - Changing the location server or the WCS time zone will not change the location history time stamp. The time zone is determined by the browser's locale.

· Location Server (CSCsa96308) - Once contributing Access Points are synchronized with the location server, changing the contributing APs will not affect the location from the location server.

Interoperability Tables
