Important Notes
This section describes important information about Cisco WCS.
Cisco WCS Upgrade
When you are upgrading from release 2.2.25.0 or later, the existing Cisco WCS backup procedure and the new restore and upgrade instructions are in the Cisco Wireless LAN Solution Product Guide. A backup from a Cisco WCS for Linux cannot be applied to a Cisco WCS for Windows or vice versa.
Note
Compatibility
This release of Cisco WCS for Linux is compatible with Wireless LAN Controller and Cisco lightweight access point operating system Release 2.2 or later.
MCS7800 Servers
Cisco MCS7800 servers are not supported as Cisco WCS servers.
Changing Static WEP Key Indexes
Changing the static WEP key index on a WLAN fails. Change the WEP key index by deleting the WLAN and recreating the WLAN with the correct WEP key index.
Cisco WCS Physical Location and IP Addresses
Cisco WCS is intended to be run on a robust desktop or rack-mount Linux machine in a server room, but the Cisco WCS user interface is intended be run on any Windows workstation. 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 bring Cisco WCS up after your IP configuration changes are complete.
Map Rendering
When you have more than 200 tags, clients, or rogues on a maps page, then map page rendering can be slow. The browser may temporarily freeze during the first rendering and when it renders at every refresh interval. Cisco recommends that the network operator use filters to limit the number of visible entries to under 200 for each asset type (client, tag, rogue access point, rogue client) and then save that as default view if more than 200 of any of each 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 lightweight access points. When Cisco WCS is monitoring more than 500 Cisco lightweight access points, increase the time intervals to the following values:
•
•
•
•
Manually Executing Scheduled Tasks
Manual execution of scheduled tasks (device status, client stats, 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.
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.
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 five minutes before you try to verify that the file is imported.Monitoring Cisco Wireless Services Modules with Cisco WCS
WiSMs use the service port for communication with the Catalyst 6500 Series switch supervisor (CSCsb49178). Do not use the service port to manage WiSM using Cisco WCS.
Caveats
This section lists open caveats in Cisco WCS for Linux 3.1.35.0.
Open Caveats
These caveats are open in Cisco WCS for Linux 3.1.35.0:
•
Workaround: Disable one of the NICs, reboot the Cisco WCS server, and restart Cisco WCS.•
Workaround: Either disable the second network interface card or use a remote TFTP server.•
Workaround: Run the DNS server on another workstation, fix the name resolution problem on the Cisco WCS server, or remove the local DNS server.•
Workaround: Disable DHCP on the Linux system running Cisco WCS.•
Workaround: Enter 00:00 to 00:59.•
Workaround: If you do not shut down Cisco WCS properly it does not commit the transactions to the database on the disk, and they are lost because Cisco WCS does not have transaction logging switched on.•
Workaround: Use the Map Editor for floor resizing. This is not recommended since it does not maintain aspect ratio. The purpose of the Floor -> Edit page is to change image, floor name, or other properties.•
Workaround: 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.•
Workaround: Enter the community string in both "SNMP Read Operations" and "SNMP Write Operations."•
Workaround: If the location server is in one time zone locating objects across multiple time zones, and if a network operator is in a different time zone accessing the information through Cisco WCS, then the time stamps are based on the second/Cisco WCS time zone timestamps. The time is correct for all the objects located in the second/Cisco WCS time zone.•
Workaround: Do not add invalid IP addresses as network routes.•
Workaround: Copy & Replace AP functionality only works for Cisco Aironet 1000 series lightweight access points, and works only between same models. i.e. Cisco Aironet 1000 series lightweight access point to Cisco Aironet 1000 series lightweight access point and not Cisco Aironet 1000 series lightweight access point to Cisco Aironet 1030 remote edge lightweight access point. Copy & Replace AP for Cisco Aironet 1130 series lightweight access points, Cisco Aironet 1200 series lightweight access points, Cisco Aironet 1240 series lightweight access points, and Cisco Aironet 1500 series lightweight outdoor access points and for cross models are not supported in the 3.1 operating system release.•
Workaround: Remove one of the extra spaces in the pathname and the uninstaller should work fine.•
Workaround: When searching for clients or tags by MAC address on the Cisco 2700 Series location appliances, enter the full MAC address value, separating each pair of numbers with colons. For example, enter 00:00:00:11:11:11.•
•
•
Workaround: Choose other as the antenna pattern for Cisco Aironet 1500 series lightweight outdoor access points.•
Workaround: Create a new RADIUS authentication server template with the correct value and delete the old one.•
Workaround: Scroll to the right to find the newly added Cisco lightweight access points and then place them.•
Workaround: No functionality is affected. You can verify the model number from the Wireless LAN Controller web user interface.•
Workaround: Set the transmit power level to either 1 or 2.
Resolved Caveats
These caveats are resolved in Cisco WCS for Windows Release 3.1.35.0:
•
•
•
The following fixes have been applied: When Cisco WCS discovers a new Cisco Aironet lightweight access point with no radios, it does not add it. Also, Cisco WCS now provides a way to search for all unassociated Cisco Aironet lightweight access points and remove them from the Cisco WCS database.•

Opening a TAC Case
Using the online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer.
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
