Software Information
Cisco WCS 3.2.68.0 is now available. As new releases become available for Cisco WCS, consider upgrading.
Finding the Software Release
To find the software release Cisco WCS is running, refer to the Cisco Wireless Control System Configuration Guide. If WCS is already installed and you are connected, verify the software release version in the Help > About the Software option.
Upgrading to New Software
For instructions on installing a new Cisco WCS software release, refer to the instructions in the Cisco Wireless Control System Configuration Guide.
New Software Features in Release
Multiple WLANs can use the same WEP key index (referenced as resolved bug CSCsd46973).
Important Notes
This section describes important information about Cisco WCS.
Changing Default Password
To ensure security of the application, you should immediately change the default WCS password.
Cisco WCS Upgrade
Cisco WCS for Linux supports database upgrades only from the following official Cisco WCS releases: 3.0.101.0, 3.0.105.0, 3.1.33.0, 3.2.23.0, 3.2.25.0, 3.2.40.0, and 3.2.51.0.
Compatibility
This release of Cisco WCS for Windows or Linux is compatible with wireless LAN controller and Cisco Aironet lightweight access point operating system 3.0 or later.
Single Cisco WCS per Wireless LAN Controller
The UWN is designed so that one instance of Cisco WCS can be used to configure, monitor, and operate each set of wireless LAN controllers. This design ensures that the wireless LAN controllers are properly represented in Cisco WCS (CSCsc42249).
MCS7800 Servers
Cisco MCS7800 servers are not supported as Cisco WCS servers.
Cisco WCS Physical Location and IP Addresses
Cisco WCS should be run on a robust desktop or rack-mount machine in a server room, but the Cisco WCS user interface can be run on any Windows workstation.
Workaround: If you need to change the IP parameters on the Cisco WCS workstation, such as the IP address or the default gateway, shut down Cisco WCS before making the change, and start Cisco WCS after your IP configuration changes are complete.
Map Rendering
When you have more than 200 tags, clients, or rogues on a maps page, map-page rendering can be slow. The browser may temporarily freeze during the first rendering and when it renders at every refresh interval.
Workaround: Cisco recommends that the user limit the number of visible entries to 200 for each asset type (client, tag, rogue access point, rogue client) and then save that as the default view if more than 200 of any asset type are expected on a map.
Background Policies Time Intervals
The default time intervals for scheduled policies give optimal performance when Cisco WCS is monitoring up to 500 Cisco Aironet lightweight access points.
Workaround: When Cisco WCS is monitoring more than 500 Cisco lightweight access points, increase the time intervals to the following values:
•
•
•
•
Manually Executing Scheduled Tasks
Manually executed scheduled tasks (device status, client statistics, rogue access point, and statistics) do not run immediately if any of the other tasks are already running. Instead, Cisco WCS queues and executes them as soon as the running tasks are completed.
Workaround: Wait for the manually executed scheduled tasks to complete.
Polling Intervals
The poll interval for Cisco 2700 series location appliances is the time between polls (CSCar15324). When the poll interval is set to 1 second, and the actual poll takes 20 seconds, the start of each poll is 21 seconds apart.
Workaround: Wait for the polling interval to complete.
Slow Imports of FPE Files with More Than 200 Walls
Importing a floor plan editor (FPE) file with more than 200 walls can be slow, and the browser may not report any status or redirect you to any other page.
Workaround: Do not click anywhere on the map page for at least 5 minutes before you try to verify that the file is imported.
Calibrating the Location Model Using Cisco Aironet 802.11a/b/g Wireless Cardbus Adapter Clients
Cisco Aironet 802.11a/b/g Wireless Cardbus Adapter (AIR-CB21AG) clients are not ideal for calibrating the location model (CSCsb52149). The AIR-CB21AG clients do not send the SSID in the probe request when the Broadcast SSID is disabled on the wireless LAN controller.
Workaround: Use an approved wireless client, such as Netgear WAG511.
Restoring an Upgraded Cisco 2700 Series Location Appliance to an Earlier Release
A backup from the latest release of Cisco 2700 series location appliance software cannot be restored on a location appliance running an earlier release (CSCsb54606).
Workaround: Before you upgrade a location appliance to the latest release, Cisco recommends that you create a backup for the earlier release and archive it in case you need to return an upgraded location appliance to an earlier release.
Managing Cisco Wireless Services Modules using Cisco WCS
Unlike other wireless LAN controllers, Cisco Wireless Services Modules (WiSMs) use their service ports to communicate with the Cisco Catalyst 6500 series switch supervisor. The Cisco WCS server uses the WiSM data port to connect to and control the WiSM and its associated Cisco lightweight access points (CSCsb49178).
Using the Cisco WCS Map Editor Tool
Creating a map directly by using a file image from the floor plan editor (FPE) tool is no longer allowed in Cisco WCS. The option to import this type of file is not present in the user interface and attempting to import the file causes Cisco WCS to generate a message indicating that the user needs to enter a valid JPG or PNG image (CSCsb04081). The workaround is to create a map with a regular image and later use the option to edit the floor and reimport the map image with an FPE file. The FPE tool is no longer supported in Cisco WCS. Users are encouraged to use the new Map Editor tool provided within Cisco WCS to draw obstacles, etc.
Using Microsoft Windows 2003 Browsers with Cisco WCS
Browsing on Windows 2003 Cisco WCS servers is not recommended because recommended Windows 2003 security settings cause browsing problems.
