Operating Systems Requirements

The following operating systems are supported:

Windows 2003/SP2 and Windows 2003 R2/SP2 32-bit installations with all critical and security Windows updates installed.

Windows 2003/SP2 64-bit installations are not supported.

Windows 2003 32-bit installations provide support for up to 64 GB of RAM provided Physical Address Extension (PAE) is enabled. Refer to Windows documentation for instructions on enabling this mode.

Red Hat Linux Enterprise Server 5.0 or 5.1 32-bit operating system installations.

Red Hat Linux Enterprise Server 5.0 or 5.1 64-bit operating system installations are not supported.

Windows 2003 and Redhat Linux version support on VmWare ESX 3.0.1 version and above.

VmWare must be installed on a system with these minimum requirements:
Quad CPU running at 3.16 GHz, 8 GBs RAM, and 200-GB hard drive.

Individual operating systems running WCS in VmWare must follow the specifications for the size of WCS you intend to use.

WCS on WLSE Appliance

Cisco WCS on a WLSE appliance supports up to 1,500 Cisco Aironet lightweight access points, 350 standalone access points, and 100 Cisco wireless LAN controllers. The required processors is a 3-GHz Intel Pentium with 3 GB of RAM and 38 GB of free hard drive space.

Windows operating system is not supported with the WCS on the WLSE appliance.

Client Requirements

The Cisco WCS user interface requires Internet Explorer 6.0/SP1 or Internet Explorer 7.0 with the Flash plugin. The Cisco WCS user interface has been tested and verified on a Windows workstation.

Upgrading to a New Software Release

The Cisco WCS release must be the same or more recent than the controller software release. Upgrade the Cisco WCS first to prevent any unexpected problems. Cisco WCS supports database upgrades only from the following official Cisco WCS releases:

Important Notes

This section describes important information about Cisco WCS.

Regulatory Updates

Japan update—The Japanese government is formally permitting wireless LAN use of the frequencies in the W56 band for 802.11a radios. Table 1 shows the channels, frequencies, and power levels in unit of measure of the W56 band.

Table 1 Channels, Frequencies, and Power Levels for W56 in Japan

Frequency (MHz)
Maximum Power for AIR-LAP1132AG-Q-K9
Maximum Power for AIR-LAP1242AG-Q-K9













































All of the channels in the W56 band require dynamic frequency selection (DFS). In Japan, the W56 band is subject to Japan's DFS regulations. Currently, only the new 1130 and 1240 series access point SKUs support this requirement: AIR-LAP1132AG-Q-K9 and AIR-LAP1242AG-Q-K9.

Additional country support—Country codes have been added for these additional countries supported by the controller: Bahrain (BH), Costa Rica (CR), Dominican Republic (DO), Ecuador (EC), Kazahkstan (KZ), Kuwait (KW), Oman (OM), Pakistan (PK), Paraguay (PY), Puerto Rico (PR), Vietnam (VN).

Notes about Google Earth

When you launch Google Earth, this message appears:

Google Earth could not write to the current cache or myplaces file location. The values 
will be set as follows:
My Places Path:"C:\Document and Settings\userid\Application Data\Google\GoogleEarth"
Cache Path: "C:\Documents and Settings\userid\Local Settings\Application 

This is expected behavior.

Also, if you visit AP details a second time, you get an "invalid path / googleArthLradDetails was requested" HTTP status message. This Google Earth problem can be resolved by deleting the first access point details occurrence.

Refresh Controller Values

If the audit reveals configuration differences (basic or template based), you can either choose restore WCS values on the controller or refresh controller values to synchronize WCS with the controller. Choose Restore WCS Values to Controller or Refresh Config from Controller.

Restore WCS Values to Controller enforces WCS values to the controller

Refresh Config from Controller actions depends on which audit mode is selected.

When Audit Mode is Basic

When the audit mode is basic, the following applies:

If you choose refresh config from controller, a Refresh Config window opens with two options for "Configuration if present on WCS but not on device, do you wish to:"

Retain—The WCS refreshes the configuration from the controller but does not delete any devices or configurations that no longer exist in the controller configuration. For example, if the WCS database shows an AP1 but that access point is no longer present in the controller configuration, WCS does not delete AP1 from its database.

Delete—WCS deletes the configuration of the controller from its database and retrieves a new configuration from the controller. Delete is the recommended option so that WCS matches the most recent configuration you are refreshing from WLCs.

Note After a Refresh Config from Controller is performed, only the configuration objects for this controller in the WCS database are updated. Upon refresh, the WCS templates are not updated.

When Audit Mode is Template Based

When the audit mode is template based, the following applies:

Templates only get refreshed as a result of a Refresh Config from Controller. If you choose Refresh Config from Controller, a Refresh Config window opens with two options for "Configuration is present on WCS but not on device, do you wish to."

Retain—The WCS refreshes the configuration from the controller but does not delete any devices or configurations that no longer exist in the controller configuration. For example, if the WCS database shows an AP1 but that access point is no longer present in the controller configuration, WCS does not delete AP1 from its database.

Delete—WCS deletes the configuration of the controller from its database and retrieves a new configuration from the controller. Delete is the recommended option so that WCS matches the most recent configuration you are refreshing from WLCs.

Users are prompted for confirmation to disassociate templates from the configuration objects in the device. If a user chooses to disassociate the templates, the template association for the configuration objects in the device are removed.

After this, the configuration objects in the WCS database are synchronized with the device. When association is removed, the next audit compares configuration objects in the WCS database with the device.

Windows XP Cannot Load CAD Files

Internet Explorer 7 running on Windows XP cannot load CAD files because of missing DLLs (C:\Windows\system\DWMAPI.DLL). These DLLs are only present on Windows Vista.

One of the following actions can be taken:

Uninstall IE7 and install IE6.

Leave IE7 and install the missing DLLs.

User Assistant Cannot Configure Controller

User assistants cannot configure or monitor controllers. They can only configure LocalNet Users in the controller, but they must access the Configure > Controller path to configure these local net features. If you create a user assistant user under the group category, login as that user, and go to Monitor > Controller, you receive a permission denied message as expected behavior.

Deletion of TFTP Server Is Not Updated in the Configuration Backup

To add a TFTP server you click Configure > Controller Templates, choose TFTP server from the left sidebar menu, and choose Add TFTP Server from the drop-down menu. To add the TFTP server, you give details of the name and IP address and click Save. If you later delete this TFTP server and perform a configuration backup (Administration > Background Task > Configuration Backup), the IP address of the TFTP server still shows in the TFTP Server window when only the default server should be shown.

Conflicting Ports Interrupt WCS Start

WCS fails to start if there is a conflicting port in use. You receive a "Failed to start WCS server" message, but you do not receive a list of conflicting ports. Go to WCS/webnms/logs/wcs-0-0.log and view the conflicting ports. In Windows XP and Windows Server 2003, enter NETSTAT -0 to get a list of the process ID associated with each connection. In the Task Manager, you see the respective PID and can stop the process using the port that WCS requires.

New and Changed Information

New Features

This release does not include new features.

Changed Information

There is no deployment restriction on the number of hybrid-REAP access points per location. However, the minimum bandwidth restrictions remains at 128 kb/s with the roundtrip latency no greater than 100 ms and the maximum transmission unit (MTU) no smaller than 500 bytes.


This section lists Resolved Caveats and Open Caveats in Cisco WCS for Windows and Linux.

CSCsq72345—The WCS solid database no longer shuts down when the size exceeds 13 GB.

Open Caveats

These caveats are open in Cisco WCS

CSCsg74466—If you choose Monitor > Devices > Access Points and select Noise/Interference/Coverage (RSSI/SNR) to generate a report, the legend of the report overlays the actual chart display area.

Workaround: You can instead view the report on the WLC.

CSCsh44930—In the Clients Summary page (Monitor > Clients), typing the MAC address for a mobile client in the Client field and clicking the Troubleshoot button does not open up the Client Troubleshooting window.

Workaround: Search for the client by its MAC address using the Quick Search field and click the link for the returned client to go the Client Details page. On the Client Details page, choose Troubleshoot from the Command drop-down list and click GO.

CSCsh81856—While installing, the password field is only partially encrypted.

Workaround: Only one or two of the letters show up during installation. After the password is created and the user clicks Enter, the screen proceeds to the next session.

CSCsh82165—Upon install or uninstall, the following error message sometimes displays: " ): process completed before monitors could start."

Workaround: This message is irrelevant. No workaround is necessary.

CSCsi26963—The Client Association report does not include any records older than 7 days.

Workaround: None at this time.

CSCsj16153—You cannot simultaneously troubleshoot two different clients from the same WCS.

Workaround: None at this time.

CSCsj18398—When setting up a WLAN from WCS, a WPA or WPA2 choice does not forward to the 4.1 version controller.

Workaround: You must choose WPA/WPA2 (instead of individual WPA or WPA2) for controller version 4.1 and greater.

CSCsj36002—The logs that get generated while troubleshooting a client cannot be truncated into 2 MB files.

Workaround: None at this time. However, this has no adverse effect on functionality.

CSCsj61673—The event log for the client gets duplicated after some time has passed.

Workaround: Click Stop to terminate the event log capture after the log has been retrieved.

CSCsj72272—You cannot enable the Accept Signed Certificate option on the Configure > Controller Template > AP Authorization page.

Workaround: You can perform this operation on the Configure > Controller > Security > AP Authorization page with the Edit AP Policies option from the Select a command drop-down menu.

CSCsj77046—If you add controllers (with comma separation) which are combinations of WiSMs (2000s and 4400s), the status messages makes it appear as if only the WiSMs were added.

Workaround: On the Configure > Controllers page, you can see a complete list of controllers that were added successfully.

CSCsj96574—When adding guest user accounts using a CSV file, you may receive an unknown exception error from the import operation.

Workaround: Make sure you format the file correctly and retry the operation. The correct sequence of fields per row is username, password, lifetime, description, and then disclaimer.

CSCsk01665—If you add any template with a negative test case and try to apply the template to the device, the object is not created in the device, even though the Apply To field is incremented.

Workaround: Confirm if the object is added by logging onto the device and using an audit to check the configuration.

CSCsk02071—The following error message occurs when loading a CAD file in maps:

Error in getting data from server. Make sure you have connectivity and server is UP. 

Workaround: Add the .dll files in the following locations and restart the WCS server:


CSCsk12424—An invalid CSV file results in an unknown exception on the migration template.

Workaround: Create a CSV with a valid format.

CSCsk17031—The history page loads slow when trying to view the location history of a tag or client.

Workaround: Make sure the history interval for client, tags, rogue clients, and access points is not significantly high on the Location Server > Administration > History Parameters page. You can also frequently purge the data.

CSCsk18826—Cisco WCS might experience slower refresh and rendering times (in Location > Synchronization) when managing large controller networks (200 or more) because of increased page synchronization requirements. Additionally, the CPU use for the web browser increases substantially and the browser might be unresponsive for a short period of time.

Workaround: Wait for the page to load completely.

CSCsk25417—All clients are displayed if you click any header to resort WGB clients.

Workaround: Choose Monitor >WGB to reset the list of WGB clients.

CSCsk28639—The restore configuration system command is not working.

Workaround: Restore the templates individually or access the controller to make the changes there.

CSCsk28942—While omnidirectional antennas' radiation pattern may have some asymmetry, they generally radiate in all directions. This causes confusion trying to set antenna orientation and position access points in WCS. When Cisco omnidirectional antenna products are chosen, the setting for omni products should be disabled since the specifications of the antenna are known. The following Cisco products should have omnidirectional patterns considered: AIR-ANT5959, AIR-ANT4941, AIR-ANT2422DW-R, AIR-ANT1728, AIR-ANT2506, AIR-ANT3213, AIR-ANT24120, integrated AP1120 antenna, integrated RM21A antenna, AIR-ANT5135D-R, AIR-ANT5135DW-R, AIR-ANT5145V-R, AIR-ANT5160V-R, AIR-ANT58G9VOA-N, AIR-ANT5175V-N, AIR-ANT2455V-N, and integrated AP1130AG antennas.

Workaround: Set the antenna orientation value to 0.

CSCsk31842—WLC fails to join WCS if a NAT/PAT is in place.

Workaround: Downgrade to

CSCsk41869—If you apply a template and then reapply the same template, the sort process returns an exception.

Workaround: None at this time.

CSCsk45060—Within access point templates, the WLAN profiles in the WLAN override list are retained even when profiles are no longer used on any controllers.

Workaround: None at this time.

CSCsk45607—An error should appear when a snmpv3 user enters less than 12 characters for an AES cipher authentication password.

Workaround: None at this time.

CSCsk48985—If you change template parameters of an existing template and then apply it to a different number of controllers, the window shows the template as applied to the original number of controllers.

Workaround: If you need to change parameters in a template, create a new template.

CSCsk51302—When you click on Client Troubleshooting in Monitor > Clients, an "object switch does not exist" error displays.

Workaround: None at this time.

CSCsk55160—If you switch between perimeter and rectangle in the planning mode tool, the total coverage area does not change, and the message above the radio buttons does not update.

Workaround: Adjust the size of the rectangle to approximately cover the perimeter area. Generate the report in either perimeter or rectangle mode.

CSCsk78181—The Automatic Client Troubleshooting Logs or CCXv5 Test Analysis generates a frame log .cap file, but the file does not contain any frames data.

Workaround: None at this time.

CSCsk79095—On the client detail page for WGB clients (Monitor > WGB), the drop-down menu contains options which are not relevant to the WGB clients. If you choose radio measurements, V5 statistics, operation parameters, and so on, a misleading message appears.

Workaround: None at this time. Commands related to the radio do not apply to WGB clients.

CSCsk81958—Clients that are connected to autonomous access points are showing as rogue clients.

Workaround: None at this time.

CSCsk87607—When a location accuracy test is tracking a large number of elements and it is left in the enabled state for a number of days, large log files might fill the logs directory. A subsequent download of a given log file might timeout given the size of the file.

Workaround: Log into the location server via SSH and move or remove log files of the following format: rf-MAC-address.log (rf-00-oc-5c-07-18.log) from the /opt/locserver/logs directory.

CSCsk88821—When creating maps, the floor information for a building is not retained, and WCS displays an error.

Workaround: None at this time.

CSCsk91931—Even if rogue entries are made into the WCS template with uppercase MAC addresses, the WLC and WCS always show them as lowercase. This results in an audit error.

Workaround: Use only lowercase for known rogues.

CSCsl08696—If you establish an RF calibration model under WCS > Monitor > Maps > RF Calibration Model, you cannot change the name. This occurs in WCSs running version and

Workaround: None at this time.

CSCsl12804—When you test the link between the controller and the client using Link Test, the ping results or RSSIs fail for some authenticated clients and voice clients. An error message that appears says the connection requires an associated client when in actuality it requires authenticated clients.

Workaround: None at this time.

CSCsl38408—When you press the Exit or Save button, the map editor does not exit.

Workaround: You can close the window by pressing X on the right-hand side of the browser.

CSCsl38717—After a guest user template is created and applied, some of the attributes are represented incorrectly when the template is revisited. For example, the status of the user account may show as expired rather than active.

Workaround: Delete the existing template and create and apply a new one.

CSCsl40179—The CSV file contains a typo. It should read csv-telnetpassword.jpeg instead of csv-tenetpassword.jpeg.

Workaround: None at this time.

CSCsl42250—When running concurrent user sessions on WCS, some access pages take a very long time to display.

Workaround: None at this time.

CSCsl42358—In a quick search, the substring matching function returns more data than the matched strings.

Workaround: None at this time

CSCsl48403—When you import an access point configuration, you get an unwanted WCS prefix before the access point names in the status message.

Workaround: None at this time.

CSCsl48483—The access point name gets updated in the access point link but not in the Config > Access Point page where all the access points are listed.

Workaround: None at this time.

CSCsl51188—WCS does not update the friendly internal state for a rogue access point when the same MAC is present on two WLCs.

Workaround: None at this time.

CSCsl53478—The access point goes into pending state while searching for access points using Monitor > AP and does not retrieve the results.

Workaround: Search for access points from a different page, such as the Monitor page.

CSCsl53595—When the controller information on the access point is imported through the Import AP Config feature, the access point gets updated but the error message returns that it was not updated.

Workaround: None at this time.

CSCsl53612—The first and last information which appears for rogue access points on maps does not appear.

Workaround: None at this time.

CSCsl53950—The icon for single radios appears incorrectly on the floor map. For example, if you choose 802.11a/n, the 802.11b/g radio shows as green when it should be gray. When the map is initially launched, the status shows correct, but when you change the protocol, the status is wrong until the map is launched again.

Workaround: None at this time.

CSCsl54522—The port number that displays in the pop-up when you mouse over a client icon map might differ from the port number that displays in the client general properties panel when you click on the client icon on the map. These port values should be the same.

Workaround: Use the port value that displays on the client general properties panel.

CSCsl57064—When an administrator tries to create a wired guest user within WCS, an error message appears.

Workaround: The wired guest user interface can be created on the controller instead of WCS. The created wired guest user interface can then be pushed to WCS through the refresh config from a controller command.

CSCsl57546—When WCS is displaying a rogue device, it sometimes shows the detecting access point's MAC address instead of its name depending on the detection method used. If WCS discovers the rogue through a poll, it uses the MAC address of the access point for a name. If WCS discovers the rogue by a trap from a WLC, it uses the name.

Workaround: None at this time.

CSCsl63991—The status message does not display tertiary controller information after you do a Config > AP > Import.

Workaround: None at this time.

CSCsl64243—The status of the tertiary controller does not show up in the log.

Workaround: None at this time.

CSCsl73139—The channel utilization for mesh access point for backhaul interface does not match that of regular maps and Google Earth maps.

Workaround: None at this time.

CSCsl73205—When a rogue is detected as friendly on one controller, the rogue state is not always updated from malicious to alert to friendly.

Workaround: If you execute the rogue access point background task multiple times, the rogue state on the controller is updated.

CSCsl75176—In some cases the access point heatmap is displayed in the upper left-hand corner instead of where the access point is placed.

Workaround: None at this time.

CSCsl76192—If you use the Apply button when in planning mode, a servletException error appears.

Workaround: None at this time.

CSCsl77797—The Location Accuracy Tool (Tools > Location Accuracy Tool) does not generate a spatial image when the map is not imported as a GIF file.

Workaround: Import maps as JPEG files.

CSCsl79802—When importing a file, the primary and secondary controller entries cannot be blank.

Workaround: None at this time.

CSCsl80359—Although the task scheduler may show guest users as expired, the Guest User template shows them as scheduled.

Workaround: None at this time.
