Release Notes for Cisco 2700 Series Location Appliances for Software Release 220.127.116.11
November 30, 2005
These release notes describe features, enhancements, and caveats for software release 18.104.22.168 for Cisco 2700 Series Location Appliances. This release of location appliance software operates with Cisco Wireless LAN Solution versions 3.2, 3.1, and 3.0.
These release notes contain the following sections:
Location appliance software release 22.214.171.124 supports Cisco 2700 series location appliances that interoperate with Cisco Wireless LAN Solution version 3.2, 3.1, and 3.0. Location appliances enhance the built-in Cisco WCS location capabilities by computing, collecting, and storing historical location data, which can be displayed in Cisco WCS. In this role, the location appliance acts as a server to one or more Cisco WCS servers, collecting, storing, and passing on the location from its associated Cisco wireless LAN controllers.
You can install this software release on any 2700 series location appliance.
Upgrading to this Software Release
For instructions on using Cisco WCS to install this software on location appliances, refer to the "Downloading Application Code to a Location Appliance using Cisco WCS" section in the "Operating Location Appliances" chapter in the Cisco Wireless LAN Solution Product Guide.

Backup of Release 126.96.36.199 Cannot Be Restored on Previous Releases
A backup from this release of location appliance software cannot be restored on a location appliance running an earlier release. Before you upgrade a location appliance to this release, Cisco recommends that you create a backup for the earlier release and archive it in case you need to convert an upgraded system to an earlier release.
This section lists new features in this release.
You can now install a complete system from a single ISO file.
Auto-Sync WCS/Location Appliance
You can automatically synchronize configuration changes made on the WCS to the location appliance or vice versa.
The location server can send notifications that are triggered by certain conditions defined in the system using WCS.
This section describes important information about location appliances.
Location History Timestamps Match Browser's Locale
The WCS timestamp is based on the browser's locale and not on the location appliance settings. Changing the time zone of the WCS or on the location appliance does not change the timestamp for the location history.
Assign a Controller/Network Design/Event Group to a Location Appliance Before Using Auto-Synch
With auto-synchronization, controllers/network designs/event groups that are detected as unsynchronized are synchronized automatically. Before this automatic synchronization can be enabled, you must assign a controller, event group, or network design to a location appliance.
Controller Name Must be Unique Before Synchronization
The assigned controller names must be unique. If the controller names are duplicated, the synchronization process occurs only on one controller.
Location Appliance Image is Gzipped
If you download the server image.gz file, the location appliance automatically unzips it, and you can proceed with the install as before. If you manually FTP the .gz file, you must unzip the files before trying to run the installer. Before downloading the .gz file to the location appliance running an earlier version, the file has to be unzipped first.
This section lists open and resolved caveats in location appliance release 188.8.131.52.
These caveats are resolved in this release:
•CSCsc38338 - When attempting to perform a backup or restore or when downloading image operations from WCS to a location server running version 1.x, a timeout error may be shown in the user interface, but the data is actually transferred. After you upgrade your location server to the 2.0 version, this situation should not occur.
•CSCsc39959—The WCS ability to search for specific elements by MAC address, asset name, and even partial entries is now available. However, when WCS 3.2 manages a location server with version 1.x, the search for specific elements returns no results. After you upgrade your location server to the 2.0 version, the situation is resolved.
•CSCsc27691—Location server images 2.0 and later are distributed in the gzip format (.gz file) while previous images were distributed in a .bin format. If you are running location server version 1.x, first decompress the image (gzip -d <imageFilename>) and then transfer and run the resulting .bin installer as usual. Upgrade your WCS to 3.2 and location server to 2.0 to transfer both .gz and .bin images.
These caveats are open in this release:
•CSCsc29336—Cisco Aironet 1230 Series Lightweight Access Points experience signal strength inconsistencies across units. These inconsistencies may alter location accuracy for access points present in the network. You should perform a location calibration to mitigate any inconsistencies on location accuracy.
•CSCsc59996—After the location server is restarted, the trace logging mode may be enabled, even if it was previously disabled by the user. Having the trace logging mode enabled does not effect the server functionality. To avoid having the trace logging mode enabled after restart, uncheck the Logging modules in the server Advanced Parameters window.
•CSCsc09186—When performing the location calibration, taking data points can take up to one minute per point if a single controller is unreachable. As a workaround, make sure all controllers are reachable during calibration or remove the controllers that are not reachable.
•CSCsc64772—When aggressive parameters are configured in the location server, such as polling for all elements every 10 seconds and saving history points every minute, the database memory limits can be reached after several days. The server would then cease responding. As a workaround, restart the server or contact technical support for help with increasing the database memory settings.

Addition to the Quick Install Guide
The Quick Start Guide: Cisco 2700 Series Location Appliance should include the following information for location appliances.
When you have a non-default port or HTTPS turned on, you must pass the correct information along with the command. For example, getserverinfo must include -port <<port>> -protocol <<HTTP/HTTPS>>. Similarly, for stopping the server, stoplocserver - port <<port>> -protocol <HTTP/HTTPS>>.
Additional Sections to the Location Appliance Installation Guide
Configuring NTP Server
You can configure NTP servers to set up the time and date of the 2700 location appliance.
The /etc/ntp.conf file is the main configuration file in which you place the IP addresses or DNS names of the NTP servers you want to use (see the following example).server ntp.mydomain.com # my corporate NTPserver 192.168.2.5 # my second NTP
To get NTP configured to start at bootup, enter the following:[root@loc-server1]# chkconfig ntpd on
To start, stop, and restart NTP after booting, follow these examples:[root@loc-server1]# service ntpd start[root@loc-server1]# service ntpd stop[root@loc-server1]# service ntpd restart
After configuring and starting NTP, make sure it is working properly. To test whether the NTP process is running, use the following command:[root@loc-server1]# pgrep ntpd
You should get a response of plain old process ID numbers.
Enter the ntpdate -u<serverIP> command to force your server to become instantly synchronized with its NTP servers before starting the NTP deamon for the first time (see the following example).[root@loc-server1]# service ntpd stop[root@loc-server1] ntpdate -u 192.168.1.100Looking for host 192.168.1.100 and service ntphost found: ntpl.my-site.com12 Aug 08:03:38 ntpdate: step time server 192.168.1.100 offset 28993.084943 sec[root@smallfry tmp]# service ntpd start
For more information on the NTP configuration, consult the Linux configuration guides.
