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 with 8 GB RAM and a 200-GB hard drive.

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

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.

Browsing on Windows 2003 Cisco WCS servers is not recommended because recommended Windows 2003 security settings cause browsing problems.

The client running the browser must have a minimum of 1 GB of RAM and a 2-GHz processor. The client device should not be running any CPU or memory-intensive applications.

Note The screen resolution should be set to 1024 x 768 pixels for both WCS and Navigator.

Wireless LAN Controller Requirements

Cisco WCS supports management of the following wireless LAN controllers:

Location Server, Mesh, and MSE

Cisco WCS supports management for the following location server, Mesh, and Mobility service engine (MSE) software:

MSE release and Context Aware Software

Note Client and tag licenses are required to retrieve contextual (such as location) information within Context Aware Software. See the Release Notes for Cisco 3350 Mobility Service Engine for Software Release for more information.

Location server

Location appliances operating with release 4.0 are compatible with Cisco WCS release 5.0. Location appliances operating with release 5.1 are compatible with Cisco WCS release 5.1.

Location appliance software is backwards compatible with the previous two location appliance releases. Therefore, you can only upgrade two releases forward. For example, you can directly upgrade from release 3.0 or 3.1 to 4.0 but you cannot directly upgrade to release 4.0 from releases 1.1, 1.2, 2.0, or 2.1.

Note AMD processors that are equivalent to the Intel processors are also supported.

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

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 connected, verify the software release by choosing Help > About the Software.

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:

Note You cannot auto upgrade from to using Red Hat Linux Enterprise Server 5.0 (refer to bug CSCsq27887). You must initiate the manual upgrade process to do the upgrade. See the "Upgrading to WCS" section in the Wireless Control System Configuration Guide.

Important Notes

This section describes important information about Cisco WCS.

Configure > Location Sensor

The location sensor option on the WCS GUI is not supported in WCS

Internet Explorer Error

When you click certain links that call Javascript code, you may get an Internet Explorer error as follows:

Problems with this web page might prevent it from being displayed properly or functioning properly. In the future, you can display this message by double clicking the warning icon displayed in the status bar.

This problem appears if another program has de-registered the DLLs below. Re-registering them corrects the problem.

Follow these steps to re-register the DLLs:

Step 1 Open a command-line window in Windows XP (Start > All Programs > Accessories > Command Prompt).

Step 2 Run these commands one at a time in the following order. After each command has successfully run, you should receive a pop-up message that the DllRegisterServer in_something.dll succeeded.

1. regsvr32 msscript.ocx

2. regsvr32 dispex.dll

3. regsvr32 vbscript.dll

4. regsvr32 scrrun.dll

5. regsvr32 urlmon.dll

6. regsvr32 actxprxy.dll

7. regsvr32 shdocvw.dll

Step 3 Restart the computer.

Cisco WCS Supported on Windows 2003 English and Japanese Operating Systems Only

Cisco WCS is supported only on English or Japanese versions of the Windows 2003 operating system. Display problems sometimes occur when you install and run Cisco WCS on operating systems translated to other languages or with location settings other than English or Japanese.

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 the AP Details window 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 AP 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 present only on Windows Vista.

Take one of the following actions:

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 in the group category, log in 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, 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, enter the name and IP address and click Save. If you later delete this TFTP server and back up the configuration (Administration > Background Task > Configuration Backup), the IP address of the TFTP server still appears in the TFTP Server window when only the default server appears.

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. Enter the following to get a list of the process IDs associated with each connection:

In Windows XP and Windows Server 2003, enter netstat -na0.

In Linux, enter netstat -nlp.

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

The following new features are available in WCS

Note Refer to the Cisco Wireless Control System Configuration Guide, Release 5.1 for details and configuration instructions for each of these features.

New Dipole Antenna Support in Cisco WCS—This feature provides support for heat map views of the antenna coverage pattern in Cisco WCS. Supported antennas include:

5 GHz, 3.5 dBi: AIR-ANT5135DW-R, AIR-ANT5135DG-R

2.4 GHz, 2.2 dBi: AIR-ANT2422DW-R, AIR-ANT2422DB-R, AIR-ANT2422DG-R

Cisco Aironet 1250 Series Support for One or Two Antennas per Radio—With this release, the Cisco Aironet 1250 Series radio module can be configured to operate with only one or two antennas.

Payment Card Industry (PCI) Assessment and Reporting—WCS PCI Reporting analyzes Cisco Unified Wireless Network (CUWN) security event data, such as rogue and attack events from Wireless IDs, as well as network-wide configurations and audit trails for PCI compliance. Potentially non-compliant events and network configurations are summarized in a WCS PCI report.

Detailed Client Report—Client information can be viewed from a tabular client report with a customized display. This report tracks up to one year of client history. The clients in the report can be sorted based on variety of criteria, including floor area, controllers, access points, Service Set Identifiers (SSIDs), or client MAC addresses or names.

RRM Support for 802.11n 40-MHz Channels—With this release, 40-MHz channels can be automatically configured on the Cisco Aironet 1250 Series Access Point using Cisco WCS or the WLAN controller. This feature applies only to 5-GHz radios and is not supported on the 2.4-GHz radios.

RRM Dashboard in Cisco WCS—The WCS provides troubleshooting and network diagnostics in an easy-to-read, graphical interface. The RRM dashboard includes:

Access points with most channel changes

Access points running at maximum power

Access points with coverage hole events

Top channel change reasons

Access Point Failover Priority—Network managers can configure priorities for lightweight access points in the event of a controller failover. In the event a primary controller goes offline and a backup controller is saturated, the higher priority access points are allowed to join the backup controller.

Cisco WCS Virtual Domains—Cisco WCS virtual domains/partitioning allows individual IT administrators to manage the segment of the wireless network under their responsibility. Cisco WCS virtual domains can be grouped by hierarchical domains. Users can be restricted to discrete infrastructure components or service entities:

Infrastructure components include: controllers, lightweight access points, standalone (autonomous) access points, configuration templates, rogue access points, rogue ad hoc access points, summary page, events, alarms, tags, clients, event groups, chokepoints, and spectrum experts.

Service entities include guest access and location servers.

Common network management features, including searches, reports, role-based access control (RBAC), and RADIUS/TACACS+ have been enhanced to support virtual domains.

Configuration Auditing—You can audit the configuration of each wireless LAN controller to confirm that its running configuration is identical to the configuration listed in the Cisco WCS database.

Configuration auditing can be performed at three different levels:


Entire network

Set of templates against current device configuration by Config Group > Audit

In 5.1, the following audit modes are supported:

Basic audit (the legacy audit: This audit is performed on device configuration in WCS database against current WLC configuration.)

Template based audit (a new enhancement: This audit is performed against current WLC configuration on applied templates, config group templates which have been selected for background audit, and device configuration objects in the WCS database whose configuration has no corresponding template.)

Note When you apply the audit against the WLC configuration, the network or controller audit enforces WCS values for the discrepancies found if you chose enforcement in the config group template.

The setup for using basic audit and template based auditing requires two independent management tasks.

Template Usability Enhancements—Organizations can reuse and apply templates to one or all wireless LAN controllers. When attempting to delete any template, you are prompted to indicate whether the template configuration should be removed from controllers as well as Cisco WCS. New templates are identified by their template name. Existing templates are listed on the template drop-down menu.

Template Scheduling and Status—Access point templates or schedulable configuration groups can be set for a future day or time. The following information about scheduled tasks for Cisco WCS templates is provided:

Summary page of scheduled tasks

History of the success or failure status of scheduled tasks for up to 31 days

Ease of Use Enhancements—The following Cisco WCS ease-of-use enhancements are included in this release:

Customization of column order and display is added to the Client Association Report

Flex-based interactive charts are now available for viewing client statistics, including bytes sent and received, signal-to-noise ration (SNR), and received signal strength indication (RSSI).

Automated Wireless Security Vulnerability assessment—The Cisco WCS audits the security posture of wireless network configurations, including wireless LAN controllers, access points, and management interfaces against wireless security best practices defined by Cisco. WCS provides an at-a-glance security score, a prioritized summary of vulnerabilities, and suggested remedies.

Enhanced WCS Security Dashboard—WCS delivers a comprehensive security summary status of the entire wireless network with an easy to reference chart. It also provides a real-time summary of network security alarms, attempted attacks, and potential security vulnerabilities. WCS streamlines information by dynamically displaying only current alarms and allowing access to additional details on any event. WCS displays wired network security events, such as wireless client abuse of a wired network, and provides Layer 3 through 7 malware detection reporting from wired network security devices.

Cisco WCS Integration with Cisco Secure Access Control Server (ACS) View Server 4.0—The Cisco WCS client troubleshooting tool now integrates with Cisco Secure ACS View Server to provide aggregated client status information from multiple Cisco ACS Servers.

Organizations can poll Cisco Secure ACS View Server through the Cisco Secure ACS tab located on the Cisco WCS client troubleshooting tool user interface. With this tool, you can determine the cause and reason of client authentication failures.

Rogue Switch-port Tracing and Disable—The WCS verifies the switch port to which a rogue access point on the network is connected and upon identification, disables the port.

Access Point Wired Port Authentication with 802.1X—WCS authenticates access points plugged into a wired network port using 802.1X to validate credentials. It also provides secure access point provisioning and consistent policy enforcement throughout the network.

Network Access Control (NAC) Out-of-band Support—The Cisco Unified Wireless Network enables use of the NAC Appliance in out-of-band mode with guest and general WLAN traffic. It also allows for posture assessment and remediation upon authentication and polling of traffic to help ensure that clients connected to the network comply with current security configuration requirements.

Green Initiative—Improved power management of Cisco Aironet access points to support the Cisco Green initiative. Cisco access points can be turned on or off periodically at scheduled intervals to save power

Changed Information

There is no deployment restriction on the number of hybrid-REAP access points per location. However, the minimum bandwidth restriction 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 open and resolved caveats in Cisco WCS for Windows and Linux.

Open Caveats

These caveats are open in Cisco WCS

CSCsg74466—On the Monitor > Devices > Access Points page, when Noise / Interference / Coverage (RSSI / SNR) is selected and a report is generated, the report displays a chart that has the legend overlaying the chart display area.

Workaround: None. The chart can also be viewed on the WLC user interface.

CSCsh44930—When you enter a client MAC address and click on Troubleshoot, client troubleshooting does not start.

Workaround: Use the search framework to enter the MAC address. When the client is returned, go to the client detail page and choose Troubleshoot from the Select a command drop-down menu.

CSCsh81856—While you install WCS on Linux, the password field is only partially encrypted.

Workaround: None.

Note Only one or two of the letters show up during installation. If the partially encrypted password field occurs, it only occurs once while creating the password. After you create the password and click Enter, the next installation prompt appears.

CSCsh82165 —During the installation and uninstallation of WCS or Navigator, the following error message occasionally appears on Linux devices: process completed before monitors could start.

Workaround: Because the error message has no effect, a workaround is not required.

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

Workaround: None.

CSCsj36002—When you troubleshoot a client, the generated logs are not truncated into files of 2-MB size.

Workaround: None. Issue has no adverse effects on functionality.

CSCsj61673—The event log generated for the client is duplicated after a time interval.

Workaround: Stop the event log capture by clicking Stop when the log has been retrieved.

CSCsj72272—The WCS does not provide the option to enable the SSC certificate for converted access points from the Configure > Controller Template > AP Authorization menu.

Workaround: Connect on each WLC and enable the option "Accept Self Signed Certificate."

CSCsj77046—The controller addition message mentions only WISMs.

Workaround: Go to the Configure > Controllers page to see the complete list of successfully added controllers.

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

Workaround: Confirm the correct information by logging onto the device, or use the audit from the configuration side to confirm.

CSCsk15266—The IP address shown in the CDP Neighbor tab in Monitor > AP is incorrect. For example, if the IP address is A.B.C.D, it is shown as D.C.B.A.

Workaround: None.

CSCsk17031—When you try to view the location history of a tag or a client, the history page loads slowly.

Workaround: Under Location Server > Administration > History Parameters, make sure the history interval for client, tags, rogue clients, and access points is not too excessive. Make sure data pruning happens more frequently.

CSCsk31174—After an access point is migrated from autonomous to unified, the location information of an autonomous access point is not migrated if device status polling and wireless polling are disabled. The access point is discovered, but the location information previously entered as an autonomous access point is not carried over. The information must be re-entered.

Workaround: Do not disable device status and wireless status polling.

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

Workaround: None.

CSCsk45607—When an SNMPv3 user with privacy and an authentication password enters an AES cipher with less than 12 characters, an error should be returned.

Workaround: No functionality problems exist because of this missing error message.

CSCsk77484—If the controller to which the access point is associated has more than 15 SSC access points, migration takes longer than expected.

Workaround: Set the session timeout value on the controller to 1.

CSCsk78181—Frame Logs file(cap) does not contain frames data in the file.

Workaround: None.

CSCsk79095—On the client detail page for WGB clients, some tabs and commands appears that are not applied to a WGB client. Selecting one of these commands may cause WCS errors.

Workaround: None required. Avoid using one of these commands.

CSCsk81958—WCS shows wireless clients connected to autonomous access points as rogue clients.

Workaround: None.

CSCsl12804—The Link Test fails on some authenticated clients.

Workaround: None.

CSCsl42250—When multiple WCS users try to concurrently log in as "root," several pages take a long time to load.

Workaround: None.

CSCsl47529—When WCS is upgraded from, the lobby ambassador cannot view passwords of guest users created in WCS

Workaround: None.

CSCsl48483—An access point name is not updated in the main access point page (import access point configuration). It is updated in the access point link, but not in the Configure > Access Point page where all the access points are listed. After a day, the change is applied.

Workaround: None.

CSCsl53950—The Alarm Status on the access point icon for single radios displays incorrectly in maps. For example, if you select protocol = 802.11a/n, the access point icon for b/g radios displays as green instead of gray.

Workaround: Re-launch map to display the correct status.

CSCsl63991—When you use the import config feature, the Tertiary Controller Name is not updated; information regarding this failure does not show up in the status message.

Workaround: None.

CSCsl82286—WCS TFTP uploads may fail when running 4.2.62.x.

Workaround: Configure WCS to have the TFTP server on the same partition of the hard disk as the WCS installation.

CSCsl82677—When a hostname is not present for the access point, the MAC address is not replaced in the import status messages.

Workaround: None required because the status message has no effect on functionality.

CSCsm13536—The channel bandwidth is listed differently for the 20-MHz and 40-MHz range of an 802.11n access point.

Workaround: None.

CSCsm20294—When the primary controller and secondary controller are not configured in the access point, the access point fails the import process. The following error message appears: "AP4 primaryMwar and secondaryMwar entries Maz40 are not configured in WCS."

Workaround: None.

CSCsm35824—The restore operation fails after consecutive restores.

Workaround: Attempt the restore operation a second time.

CSCsm58636—On the WCS Configure > Access Point page, incorrect maximum power values appear for certain channels that exceed FCC approval for that channel.

Workaround: None.

CSCsm75896—When you audit WLC from WCS, the following error message appears after you attempt a Restore Config: Restore Config Report Restore failed for following configuration(s) Name Error "StdSignaturePattern <IP address/ID> - MIB access failed." This error occurs if there are extra or missing standard signatures on WLC compared to what WCS has in its database for that WLC.

Workaround: None; restoring WCS signatures is not possible on WCS.

CSCsm80253— DHCP failure in client troubleshooting provides unclear messages.

Workaround: None.

CSCsm80303—When an administrator tries to troubleshoot a client with 802.1x security settings and has the wrong credentials, WCS shows the status as green instead of red. A message is returned that states 802.1x authentication failure, which is correct, but the status icon should be red.

Workaround: None.

CSCsm89434—When a virtual domain is created or updated with a large number of controllers or access points, it may take several minutes.

Workaround: None.

CSCsm96761—When you run a Client Report > Client Association, duplicate lines for every event such as associate or disassociate are reported.

Workaround: None.

CSCsm98662—In Monitor > Clients, the client statistics values display zero in the table.

Workaround: None.

CSCsm98667—Saving a client search sometimes creates two copies of the same search or creates one copy and displays the following error: "Search with this name already exists."

Workaround: None.

CSCsm99598—A blank page appears when the ID certificate is downloaded from Configure > Controller > Security > ID Certificate. The certificate download is unsuccessful.

Workaround: Download the ID certificate from the controller GUI.

CSCsm99662—The Network Access Control Security Template accepts invalid server IP addresses without displaying warning messages.

Workaround: Do not configure NAC templates with invalid IP addresses.

CSCso07969—A DECT phone will not show as an interferer with an SAgE2 card.

Workaround: Include another interferer besides a DECT phone or use an SAgE1 card.

CSCso13473—In WCS, the error message contains the Airespace product name ACS instead of WCS when MAPs are missing for a client location.

Workaround: None.

CSCso35098—A "Could not execute JDBC batch update" error message appears when you try to create a guest user.

Workaround: Not applicable.

CSCso36847—In the Config Group controller tab, if the controller is selected and then removed, you cannot re-select the controller.

Workaround: Exit and then return to Config Group to edit it.

CSCso40295—WCS may show incorrect values when you hover over a connected client device.

Workaround: None.

CSCso43619—There are irregular breaks in some of the client monitoring graphs.

Workaround: None.

CSCso43754—The AP801 is not shown in the access point list during the conversion process.

Workaround: Use the "Select CSV File" option and provide the .csv file name.

CSCso49557—The Tools > Voice Audit page takes a long time to load when a report was previously created.

Workaround: None.

CSCso53785—When you search rogue access points using a MAC address, the rogues recently retrieved from the controllers do not appear. The rogue access point trap gets disabled from WCS.

Workaround: Enable the rogue access point trap.

CSCso55108—If deletion of a RADIUS Template fails, the failure reason is displayed as "Unable to remove the Radius Auth Server from Controller as it is being used by H-REAP Group."

Workaround: Remove the RADIUS linkage in the WLAN AAA servers.

CSCso58483—WCS alerts for access point impersonation report the wrong radio band (802.11a) for slot 0.

Workaround: None.

CSCso59323—The PSK ASCII key always displays HEX under controller WLAN and templates.

Workaround: None.
