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 Any release posted after 220.127.116.11 will not be eligible for upgrade to release 18.104.22.168.
This section provides instructions for upgrading WCS on either a Windows or Linux server. It handles the steps you would normally follow to accomplish a manual upgrade (shut down WCS, perform a backup, remove the old WCS version, install new version, restore the backup, and start WCS). If you choose to use the installer, it searches for any previous WCS versions.
Note You must have software release 22.214.171.124 before you can automatically upgrade to 4.2.
If you choose to use the easy upgrade process, it provides error checking at each step and gives an informative message if an error causing an exit occurs. An upgrade-version.log is also produced and provides corrective measures.
Note For steps on upgrading WCS in a high availability environment, refer to Chapter 14 of the Cisco Wireless Control System Configuration Guide.
Using the Installer to Upgrade WCS for Windows
Follow these steps to upgrade WCS (on a Windows platform) using the automated upgrade:
Step 1 Insert the Windows Cisco WCS CD into the CD-ROM drive and double click the WCS-STANDARD-K9-6.0.X.Y.exe file where 6.0.X.Y is the software build. If you downloaded the installer from Cisco.com, double click the WCS-STANDARD-WB-K9-6-0-X-Y.exe file that you downloaded to your local drive.
Step 2 The Install Anywhere window appears and prepares the system for installation. After a few seconds, the Introduction window appears, followed by the license agreement window. You must click the "I accept the terms of the License Agreement" option to continue.
Step 3 At this point, the install wizard detects whether a previous version of WCS is installed and specifies whether the current version is eligible for an automated upgrade. If your most recent WCS version cannot participate in the automated upgrade, you receive such a notice. You must then choose Install and must switch to the manual upgrade. (Refer to the WCS Software Configuration Guide for manual upgrade instructions.) If your WCS version is eligible for an automated upgrade and the previous qualifying version of WCS is detected, choose Upgrade and continue to Step 4. This method is preferred.
Step 4 Several of the values from the previous installation are retained as part of the upgrade. These include the following:
•the root password
•the root FTP password
•the TFTP server file location
•the FTP server file location
•the multi-homed server interfaces
Step 5 Choose a folder in which to install the Cisco WCS at the Choose Install Folder window. It must be a different location than the previous installation. Click Next to continue.
Step 6 Choose a folder location in which to store the shortcuts. It must be a different location than the previous installation.
Step 7 Continue to follow the prompts that appear. You are notified when the system checks for required space, uninstalls previous versions, backs up files, restores, and so on. A prompt appears asking if you are ready to start WCS as a service. Click Yes.
Note The upgrade log is located in the standard log directory (\webnms\logs) if the automated upgrade completes. If the automated upgrade did not complete, the upgrade log is located in the user home directory.
Note If WCS is configured to use TACACS+ or RADIUS for external authentication, the custom vendor attribute list should be updated in the TACACS+ or RADIUS server with any new permissions. The attribute list for the appropriate UserGroup can be found at Administration > AAA > UserGroups. Click the Export link for the appropriate user group. Refer to Chapter 14 of the Cisco Wireless Control System Configuration Guide for additional information regarding upgrading.
Using the Installer to Upgrade WCS for Linux
Follow these steps to upgrade WCS (on a Linux platform) using the automated upgrade:
Step 1 Using the command line, perform one of the following:
a. If you are installing from a CD, switch to the /media/cdrom directory.
b. If you are installing from Cisco.com, switch to the directory in which the install file was downloaded. For example, if the install file was placed in /root/Desktop, enter cd /root/Desktop.
Step 2 Enter ./WCS-STANDARD-K9-6.0.X.Y.bin (for CD users) or ./WCS-STANDARD-LB-K9-6-0-X-Y.bin (for Cisco.com users) to start the install script.
Step 3 The Install Anywhere message appears and prepares the system for installation. After a few seconds, the Introduction appears, followed by the license agreement statement. You must accept the license agreement to continue.
Step 4 At this point, the install wizard detects whether a previous version of WCS is installed and specifies whether the current version is eligible for an automated upgrade. You receive a notification whether or not your most recent WCS version is eligible for the automated upgrade.
Step 5 If you cannot continue to the automated upgrade because your current WCS version is not eligible, choose Install and continue to the manual upgrade (refer to the WCS Configuration Guide for manual upgrade instructions). You can also choose to do a manual upgrade rather than the recommended automated upgrade by choosing Install and continuing to the manual upgrade, but this is not recommended. If your current WCS version is eligible for the recommended automated upgrade, choose Upgrade and continue to Step 6.
Step 6 Several of the values from the previous installation are retained and carried over as part of the upgrade. These include the following:
•the root password
•the root FTP password
•the TFTP server file location
•the FTP server file location
•the multi-homed server interfaces
Step 7 Choose a folder in which to install the Cisco WCS. It must be a different location than the previous installation. Click Next to continue.
Step 8 Choose a folder location to store the shortcuts. It must be a different location than the previous installation.
Step 9 Continue to follow the prompts that appear. You are notified when the system checks for required space, uninstalls previous versions, backs up files, restores, and so on. A prompt appears asking if you are ready to start WCS as a service. Click Yes.
Note The upgrade log is located in the standard log directory (\webnms\logs) if the automated upgrade completes. For an incomplete automated upgrade, the upgrade log is located in the user home directory.
Note If WCS is configured to use TACACS+ or RADIUS for external authentication, the custom vendor attribute list should be updated in the TACACS+ or RADIUS server with any new permissions. The attribute list for the appropriate UserGroup can be found at Administration > AAA > UserGroups. Click the Export link for the appropriate user group. Refer to Chapter 14 of the Cisco Wireless Control System Configuration Guide for additional information regarding upgrading.
Restoring the WCS Database in a High Availability Environment
During installation, you are prompted to determine if a secondary WCS server would be used for high availability support to the primary WCS server. If you opted for this high availability environment and enabled it in the Administration > High Availability window, the status appears as HA enabled. Before performing a database restore, you must convert the status to HA not configured.
Note If the restore is performed while the status is set to HA enabled, unexpected results may occur.
Follow one of these procedures to change the status from HA enabled to HA not configured:
•Click the Remove button on the HA Configuration window (Administration > High Availability).
•Restart the primary server. Go to the secondary HealthMonitor GUI (https://<SecondaryWCS>:8082) and click Failback.
–This procedure is used when one of the following instances has occurred:
The primary server is down and failover has not been executed, so the secondary server is in SecondaryLostPrimary state.
The primary server is down and failover is already executed, so the secondary server is in the SecondaryActive state.
The primary server will now be in HA Not Configured mode, and you can safely perform a database restore.
This section describes important information about Cisco WCS.
Duplicate AP Name
If you see access points with the same name while applying controller templates or adding them to the map, perform a refresh config. The duplicates in the database will be eliminated.
You must enter an email address when configuring high availability. WCS tests the email server configuration and if the test fails (because the mail server cannot connect), WCS does not allow the high availability configuration.
Note High availability is supported on Linux, on Windows 2003, and on VMware environments. Specific operating system support is listed in the "Operating Systems Requirements" section.
Client Session Report
The new client session report replaces the existing Client Association and Client Detail Report. If you perform an upgrade, Client Association no longer appears in the Reports menu. The data pertaining to these reports migrates successfully, and saved report entries for Client Association and Client Detail reports are migrated. However, the new ClientSessionInfo table is not populated with data from the previous reporting period; the table is populated with client-related data that occurred after upgrade. The new client detail report contains the details of association time, disassociation time, and session timeout along with details of VLAN, session length, client location, Megabit information used, SNR, RSSI, and throughput.
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 locale settings other than English or Japanese.
Notifications in Junk Email Folder
If a domain name is not set in the email settings, notifications may end up in the junk email. When the primary device is down, no email notifications are received, but the log message indicates that an email was successfully sent.
Internet Explorer Error
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 successfully runs, 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.
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 Data\Google\GoogleEarth"
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.
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.
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.
The following new features are available with WCS release 126.96.36.199.
Note Refer to the Cisco Wireless Control System Configuration Guide, Release 6.0 for more details and configuration instructions.
New Controller Platform
•Cisco 5508 Wireless LAN Controller—This controller supports up to 250 lightweight access points and 7000 clients through eight Gigabit Ethernet distribution system ports. Cisco 5508 controllers have no restrictions on the number of access points per port. However, Cisco recommends using link aggregation (LAG) or configuring dynamic AP-manager interfaces on each Gigabit Ethernet port to automatically balance the load.
Note The 5500 series controllers can run only controller software release 188.8.131.52 or later. Refer to the Cisco 5500 Series Wireless Controller Installation Guide for more information on this controller.
•Licensing—Two types of licenses are required in order to use the 5500 series controllers: an image-based license (base or wplus), which determines the feature set that the controller uses, and an ap-count license (base-ap-count or wplus-ap-count), which determines the number of access points that the controller supports (12, 25, 50, 100, or 250). The base license supports the standard base software set, and the wplus license supports the premium wireless plus (WPLUS) software set.
The WPLUS software set provides the standard base feature set as well as this functionality:
–Datagram Transport Layer Security (DTLS) data encryption for added security across remote WAN and LAN links
–Support for OfficeExtend access points, which are used for secure mobile teleworking
–Support for the 1130AG and 1240AG series indoor mesh access points, which dynamically establish wireless connections in locations where it might be difficult to connect to the wired network.
•Data Encryption—Cisco 5500 series controllers enable you to encrypt CAPWAP control packets (and optionally CAPWAP data packets) that are sent between the access point and the controller using Datagram Transport Layer Security (DTLS). If an access point does not support DTLS data encryption, DTLS is enabled only for the control plane, and a DTLS session for the data plane is not established.
Access Point Additions and Changes
•OfficeExtend Access Points—Cisco Aironet 1130 series and 1140 series access points that are joined to a Cisco 5500 series controller with a wplus license can be configured to operate as OfficeExtend access points. This feature provides secure communications from a controller to an access point at a remote location, seamlessly extending the corporate WLAN over the Internet to an employee's residence. The teleworker's experience at the home office is exactly the same as it would be at the corporate office. Datagram Transport Layer Security (DTLS) encryption between the access point and the controller ensures that all communications have the highest level of security
•Power over Ethernet (PoE)—When a dual-radio 1250 series access point is powered using 15.4-W PoE, it cannot operate at full functionality, which requires 20 W. The access point can operate with dual radios on 15.4-W PoE, but performance is reduced in terms of throughput and range. If full functionality is required on 15.4 W, you can remove one of the radios from the 1250 series access point chassis or disable it in controller software release 6.0 so that the other radio can operate in full 802.11n mode. After the access point radio is administratively disabled, the access point must be rebooted for the change to take effect. The access point must also be rebooted after you re-enable the radio to put it into reduced throughput mode.
Mesh Access Point Additions and Changes
•Controller software release 184.108.40.206 supports the following Cisco Aironet mesh access points:
–Cisco Aironet 1522 and 1524 outdoor mesh access points
The 1522 access point has two simultaneously operating radios: a 2.4-GHz radio used for client access and a 5-GHz radio used for data backhaul.
–Cisco Aironet 1130AG and 1240AG indoor mesh access points
The 1130AG and 1240AG access points have two simultaneously operating radios: a 2.4-GHz radio used for client access and a 5-GHz radio used for data backhaul.
•Dynamic Rate Adaptation—You can now set the bridge data rate to auto. When you do so, the mesh backhaul chooses the highest rate such that the next higher rate cannot be used due to unsuitable conditions for that specific rate (and not because of conditions that affect all rates).
•Intrusion Detection System (IDS)—You can disable IDS reports on outdoor mesh access points. When you disable this feature, no IDS reports are generated, which preserves bandwidth on the backhaul. When you enable this feature, IDS reports are generated for all traffic on the backhaul.
Note IDS reporting is enabled for all indoor mesh access points and cannot be disabled.
•Licensing—In order to use indoor mesh access points with a 5500 series controller, a wplus license must be used on the controller.
Note Outdoor mesh access points do not require a wplus license.
•Serial Backhaul—The 1524SB access point has two 5.8-GHz backhaul radios: one uplink and one downlink. Each radio is configured with a different backhaul channel, so there is no need to use the same shared wireless medium between the north-bound and south-bound traffic in a mesh tree-based network.
•Telnet—In previous mesh software releases, Telnet is enabled by default. However, in controller software release 6.0, controllers block Telnet sessions by default, so you need to enable Telnet if you want to use it.
New MSE Features
•Mobility Service Coexistence—The Cisco 3300 Series Mobility Services Engine (MSE) now supports coexistence of multiple mobility services. It supports adaptive wireless intrusion prevention system (wIPS) and context-aware services on the same appliance.
•License Support—The Cisco 3300 Series Mobility Services Engine now supports a 60 day mobility services evaluation license.
New WCS Features
•Ease of Use Enhancements—The following GUI changes have been made: 1) streamlined workflows and unified tab designs that reduce the number of clicks required to complete operational tasks, 2) consistent cross-links that support quick access to actionable and relevant information, 3) customized displays based on user-defined parameters that support easy filtering, adding, sorting, editing, and removal of displayed information, and 4) breadcrumb trail that retraces the user's navigation path forward and backward through a variety of WCS screens.
•Monitoring Enhancements—The following areas have been enhanced to simplify WLAN monitoring: 1) users can easily edit tab categories and contents to meet their specific requirements, 2) new floormap tool icons and interface support customization of displayed components and visualization of network status and alarms, 3) network status and alarms summary is now in the left-hand corner of Cisco WCS, 4) Cisco WCS search tool is now at the top of the interface to support simple and advanced searches, and 5) all WLAN campuses, buildings, and floor are hierachically listed in a new collapsible and expandable mapping tree, facilitating quick visualization of network locations.
•Streamlined Configuration Templates—This feature includes the following for the streamlining and simplifying of templates: 1) mouse-over feature that provides a quick description of each template, enabling users to quickly find the template the meets their requirements, 2) quick creation and scheduling of templates through an enhanced user interface, 3) over 60 configuration templates from the Controller Launch Pad (including system, WLAN, security, 802.11a/n, 802.11b/g/n, mesh, management, CLI, and location), 4) one place to see a list of the templates applied to a controller, and 5) access point configuration templates that are quickly customizable for 802.11a/b/g/n lightweight, autonomous (standalone), or mesh access points.
•Enhanced Client Management—Client monitoring has been enhanced to support quicker access to critical client information and tools across the wired and wireless network. CDP information was added to allow visibility to access point details even when the access point is disassociated from the controller. When access points are not associated to any controller, the CDP neighbor information helps to find to which switch the access point is connected. New features include: 1) client details screen with new information and an aggregation of existing information into an easy-to-read format, 2) streamlined access to the client troubleshooting tool and its step-by-step processes from anywhere in WCS, 3) access to client mobility information including how and why a client roamed across the wired and wireless network, and 4) quicker access to common tools from the client monitoring screen.
•Expanded Flexible Reporting—The new Report Launch Pad delivers fully customizable reporting that includes: 1) flexible user-defined report parameters for configuration, scheduling, sending, and saving, 2) mouse-over feature that provides a quick description of each report enabling users to quickly find the report that will meet their requirements prior to running the report, and 3) over 40 customizable reports on topics including access points, clients, controllers, inventory, compliance, guests, mesh, performance, security, and the RF environment.
•Enhanced WCS Licensing—The management of WCS licensing was enhanced.
•Dynamic Interface Template—This feature provides the ability to tie WLANs to unique VLANs.
•Switch Port Tracing Enhancements—This feature provides additional functionality to the switch port tracing that was introduced in release 5.2. It provides additional flexibility when adding switch credential information and enhances rogue access point reports.
•Guest Access Enhancements—The following enhancements were made for guest access: 1) the ability to configure default lifetime greater than one day, 2) the ability to import customized logos on the printed page, 3) the ability to print guest account credentials on a page, 4) enhanced navigation and look and feel, 5) customized print page header, 6) deletion of expired guests, and 7) the option for lobby ambassadors to see all accounts.
•Advanced AP Timers—Some advanced timer configuration for H-REAP and local mode is now available for the controller on WCS.
•WLAN Status Scheduling—This feature provides the ability to enable and disable multiple WLANs at a specified time for one or more wireless LAN controllers.
•Customer Feedback Link—Under the Help Menu is a Submit Feedback selection that allows you to provide input on the product.
•Learning Modules—Several short video clips have been added under the Help Menu to show the process for executing common tasks.
•Maps Ease of Use Enhancements—Some of the ease of use enhancements for maps include the following: 1) customizable views, 2) cloning selected campus, buildings, and floors, 3) search filters to filter campuses, buildings, and floors with specific severities, 4) automatic expansion of Tree View to first level, and 5) short cut icons to perform menu operations.
•OfficeExtend AP—This feature provides the ability to configure and manage wireless teleworker networks by extending the corporate network using a remote wireless access point.
•Client Link—Cisco Aironet 1140 and 1250 series access points support client link, a spatial-filtering mechanism used at a transmitter to improve the received signal power or signal-to-noise (SNR) ratio at an intended receiver (client). Client link uses multiple transmit antennas to focus transmissions in the direction of an 802.11a or 802.11g client, which increases the downlink SNR and the data rate to the client, reduces coverage holes, and enhances overall system performance. Client link works with all existing 802.11a and 802.11g clients.
This section lists open and resolved caveats in Cisco WCS 220.127.116.11 for Windows and Linux.
Caveats Associated with Release 18.104.22.168
These caveats are open in Cisco WCS 22.214.171.124 and are tied exclusively to that release:
•CSCsj23423—The AP template is partially visible when switching between tasks and dates.
Workaround: Refresh the page or revisit the link.
•CSCsv34264—An attempt to generate an ID certificate throws an SNMP Error.
•CSCsv34781—The user is unable to synchronize WLC to the MSE after the WLC sysname changes.
Workaround: Before deleting the WLC from WCS, unsynchronize it from the MSE, then delete; or change the sysname back to the original and then synchronize.
•CSCsw80427—A discovered H-REAP template displays the wrong PAC timeout value.
Workaround: Configure the H-REAP template from WCS instead.
•CSCsx38955—After a database restore and upon synchronization, a controller can be assigned to multiple MSEs that are running wIPS. No error message displays.
Workaround: Unassign controller wlc1 from one of the MSE and synchronize
•CSCsx72413—When you enable the Diagnostic Channel for a WLAN and apply it to a device, audit differences appear in the WLAN.
Workaround: After you apply the diagnostic channel changes to the device in WCS, run Refresh Config from Controller.
•CSCsx77870—Some configurations are missing from the Audit on Selected Parameters page.
•CSCsy07751—When adding a new config group in WCS, the "Copy Templates from Controller" feature does not function properly.
Workaround: Do not use the Copy Templates from Controller feature. Discover the templates separately and manually add them to the config group.
•CSCsy31176—When you successfully add a controller in WCS, the controller list page should appear, but instead the add controller page reappears.
Workaround: Click Configure > Controllers to go to controller list page.
•CSCsy31225—The Access Point Details page left navigation pane disappears when you click an access point link from Configure > Controllers > <controller_ip> > Access Points > Cisco APs list page.
Workaround: To navigate to the Controller page from Configure > Access Points > Access Point Details, click the controller link available for the Registered Controller field.
•CSCsy31617—The Category column under Monitor > Alarms displays an incorrect sorting order.
•CSCsy31679—WCS displays an incorrect sorting order for Audit Status located on the Monitor > Controllers page.
•CSCsy57155—Web passthrough with pre-auth ACL fails to apply to release 5.2, 4.2, and 5.1 WLC.
Workaround: Configure WLAN with pre-auth ACL on the individual controller webUI or CLI.
•CSCsy72020—WCS returns an exception when saving a WCS CLI template. This occurs when more than 400 WLAN config lines are added and the template is saved.
Workaround: Create the CLI template with less than 400 WLAN config lines.
•CSCsy74747—Ethernet switches are not partitioned. All users in all partitions can view all ethernet switches.
•CSCsy78058—When you use Advanced Search to search for Telemetry tags and attempt to save the search, WCS fails to save the search and fails to conduct the search.
•CSCsy78668—GUI buttons and the table format on the client troubleshooting page need to be updated.
•CSCsy79232—WCS fails to save the apply device status to a report if WCS contains more than 25 controllers.
•CSCsy84499—GUI buttons and the table format on the logged-in guest user page need to be updated.
•CSCsy86778—WCS allows you to assign the same profile name to a WLAN and to a guest LAN. When you search currently logged-in guest users, WCS shows inaccurate results.
Workaround: Create unique profile names for WLANs and Guest LANs.
•CSCsy89181—Sorting doesn't work correctly on some Monitor > Clients page columns.
•CSCsy89369—The same page is shown even if you click on different profile statuses.
•CSCsy94947—WCS displays an AP Authorization failed trap with the MAC address of the MSE when the NMSP session between WLC and MSE fails. When an MSE attempts to establish an NMSP session with the WLC and the authorization fails, the WLC sends a trap to WCS. This trap does not display enough information for WCS to distinguish this as an MSE-related trap. WCS defaults to an AP authorization failure trap with an MSE MAC address.
•CSCsy97570—When you click a client device on the Monitor > Client page, the client detail page takes over one minute to appear.
•CSCsy98346—After you configure a WLAN template with customized webauth pages, WLCs are not listed.
Workaround: Configure the webauth pages from the WLC UI or CLI.
•CSCsz00316—When 802.11a Status is enabled, WCS sometimes displays this message when you try to edit a data rate setting:
Row already updated or deleted by another transaction.
Workaround: Disable 802.11a Status.
•CSCsz02466—Microsoft Internet Explorer version 6 sometimes fails to display accurate results for the Client Count Customization feature.
Workaround: Use Firefox or Microsoft Internet Explorer 7 when using the Client Count Customization feature.
•CSCsz04879—When you use the Detecting APs option, you sometimes see duplicate reports or incorrect RSSI values.
Workaround: Use the WLC web GUI to look at detecting APs related data.
•CSCsz05363—The WCS location configuration template might display an incorrect location path loss configuration for the normal client burst interval if you do not check the normal client box.
Workaround: Check the normal client box before you attempt an audit.
•CSCsz05548—Client List page can sometimes take 30-500 seconds to load.
•CSCsz06840—WCS shows a difference for CDP parameters on access points after saving the Switching.
Workaround: Perform the Refresh Config from Controller. The difference does not display.
•CSCsz11535—On the WLAN configuration scheduled task page, the Selected WLANs table list is not inline with the heading and footer of the table.
•CSCsz12395—For omni-directional antennas, WCS shows the access point information with the antenna angle at 90 degrees, which makes a customer think it is a directional antenna.
•CSCsz19497—Buildings created under the Root Area appear in all virtual domains including domains to which they are not assigned. The problem happens when there are multiple virtual domains partitioned by campus and buildings, as well as buildings directly created under the Root Area.
Workaround: Move the Root Area buildings to a campus.
•CSCsz24278—Downloaded log files do not include all log files.
Workaround: Wait for a period of time and try to download the logs again. The download eventually succeeds.
Note If "wcs-X-X.logs" is included in the download, then all logs are included.
•CSCsz24549—WCS causes an audit mismatch by displaying the wrong attributes for port physical mode or by editing the port speed parameters.
•CSCsz28308—The config group template and audit results sometimes show a mismatch, even when you update the config templates from the controller.
•CSCsz29526—When you use more than one MSE or location appliance to run an accuracy test on a floor and one of the devices is running a 5.x release and one is running a later release, the accuracy test fails.
Workaround: Make sure the devices are running the same release version, or use only one device during the accuracy test.
•CSCsz33239—Under background tasks, the Controller Configuration Backup task sometimes fails with this message:
com.cisco.server.common.errors.IllegalOperationException: MEDIATION-5,TransferConfig!126.96.36.199,uploadMode,No access
Workaround: Add the controller with proper credentials.
•CSCsz34211—A rogue client discrepancy occurs on the rogue AP page.
•CSCsz39570—The AP Inventory report yields results despite the fact that no access points exist on WCS.
•CSCsz40279—Prior to version 6.0, the MSE services tracked the maximum allowable elements; starting from 6.0, licensing is enforced. When 6.0 is installed, the services come up in evaluation mode which tracks only 100 elements for CAS and 20 for wIPS. You must install a permanent license for CAS and WIPs.
•CSCsz44750—When the WCS search for tags with Telemetry option is enabled, Context Aware notifications are not updated.
Workaround: Stop and restart the MSE server; avoid a search with the Telemetry option checked.
•CSCsz45064—GUI buttons and the table format on the Monitor Mesh AP page need to be updated.
•CSCsz45172—When an ACS server sends a TACACS+ authorization reply with a long list of tasks, WCS sometimes closes the TCP connection and declares the ACS dead.
Workaround: Use Radius or shorter task lists.
•CSCsz48241—WCS displays Success for WLANs with media session snooping for unsupported controller versions.
Workaround: Even though WCS displays successfully applied WLANs with media session snooping, it fails to apply to unsupported versions of WLC.
•CSCsz48609—The MAC address format used in a wired client search field is case sensitive. Also, if a space is added in front of the MAC address, the search fails.
Workaround: Use lower case for the MAC address. Ensure there is no extra space in front of MAC address.
•CSCsz51669—On WCS, under the RRM group panel for a controller that is not a group leader, the last update time displays incorrectly.
•CSCsz51707—The WCS IE window occasionally displays Service Temporarily Unavailable when checking the access points and clients in the WCS map from both local machine and remotely.
•CSCsz53023—Upgrading a controller to 188.8.131.52 and above version does not upgrade the WLAN WEP Key size from unsupported 128-bit to 'UnKnown' or any other supported Key size. Because the MIB is not updated when a controller is upgraded, WCS does not update the Key size.
Workaround: In WCS, once a controller is upgraded, select the supported WEP Key size for the WLAN and apply it to device. This causes sync up with all WebUI,CLI, and SNMP values.
•CSCsz54353—The Monitor > Clients > Clients Detected by MSE option does not populate the Controller Name column when the client is associated to the local WLC.
Workaround: The client details page shows the correct information.
•CSCsz58150—When you apply a config group to a controller, an SNMP exception is returned.
Workaround: You must choose the correct WLC template combinations.
•CSCsz58626—An audit reveals discrepancies between SNMP communities and AP authorization after a conversion from read-write to read-only.
•CSCsz66652—A search of controller licenses using the Type filter criteria yields no results.
•CSCsz68873—When you enable or disable the Power over Ethernet (POE) option and run an audit, WCS displays a mismatch for that setting on the controller.
•Workaround: Refresh the configuration for the controller before running the audit.
•CSCsz69090—WCS displays an SSID string for wired guest LANs on the WLAN list page (Configure > WLC > WLAN), and it should display dashes.
•CSCsz69651—A download to WLC using TFTP from WCS fails with an invalid credentials error.
Workaround: Manually set the download mode as TFTP from the controller CLI and then initiate the download.
•CSCsz72241—When you restore WCS to the controller's configuration, the username is successfully forwarded to the controller but not the password.
Workaround: Manually change the access point password from the controller web UI.
•CSCsz72799—When you open WCS using Microsoft Internet Explorer and run a scheduled report that contains more than 60 selections, the browser sometimes hangs.
Workaround: Use Firefox to open WCS and run the report.
•CSCsz73267—Rogue configuration parameters including RLDP (Monitor Mode APs-Only) and auto containment options are missing from WCS.
Workaround: Configure these options on the WLC GUI.
•CSCsz75691—The coverage hole alarm values for failed clients, total client, and threshold are all 0 on the Home page.
Workaround: Enable traps for the coverage hole.
•CSCsz75749—If an SSID contains one or more braces, the report fails to display the TSM information.
Workaround: Use the client filter if the client MAC address is known.
•CSCsz75902—The wrong interface is used on high availability re-registration during VmWare setup.
•CSCsz76058—When the dynamic power control report is run, the wrong power assignment mode is returned for the monitor access point.
Workaround: Choose Configure > Controllers > 802.11a/n > Parameters for the correct dynamic power control mode.
•CSCsz78329—The online help for scheduled and on-demand accuracy is not mapped correctly.
Workaround: Launch the online help manually and look up the accuracy tool related help page.
•CSCsz78383—The VoIP call graph report takes longer than expected to display the results.
Workaround: Narrow the search criteria to fewer access point.
•CSCsz80636—If you delete an AP group template, WCS moves the access points to a default group and then resets.
•CSCsz80839—The Rogue AP Event report takes longer than expected to show the results.
Workaround: Shorten the duration by searching for specific access points or a subset of access points.
•CSCsz80919—WCS does not distinguish between voice clients and V5 clients. No alerts are given to the user.
Workaround: You can confirm voice or v5 client requests either with the web UI or CLI.
•CSCsz82240—The downstream packet delay data is missing from the TSM QoS computation.
•CSCsz84382—If discrepancies exist on the rogue AP rule detail page, they do not necessarily appear at the controller level audit.
Workaround: Do an audit at each rogue AP rule page.
•CSCsz85015—If you choose Monitor > Client > Troubleshooting, the dot1x authentication test is not getting triggered on the client side. WCS reports the test status as "not run."
•CSCsz85603—When you delete access points from the default access point group, WCS reboots the access points and they later rejoin the default group.
Workaround: Create a new access point group and assign access points to it before deleting them from the default group.
•CSCsz89419—TACACS+ Authorization packet sends PAP as authentication field type, even if set to CHAP.
Workaround: None. This does not affect any functionality in WCS.
•CSCsz91240—When you search a Client detail report by client username, WCS sometimes takes a long time to display the results. The problem occurs when the client historical database contains over one million records, and when client traps are enabled on the controllers.
1. Create the report by MAC address:
–Perform a quick search by username.
–Find the client MAC address of the username
–Run the client detail report by the client MAC address.
2. Turn off client traps on the controllers if you don't need to keep client sessions containing less than 15 minutes of granularity.
•CSCsz93996—An incorrect message appears when you try to generate a report for more than 5 access points or radios.
Workaround: Select one radio and run the above reports.
•CSCsz95495—If you make modifications to the H-REAP config (such as disabling the least latency controller join option) using access point templates, the OEAP reboots when the template is applied. This is not expected behavior.
Workaround: You can modify the access point configuration on the Configure > Controller > AP Details page.
•CSCsz96369—An "invalid type by" error is returned in the Client Sessions report if you upgraded from version 4.2 or 5.2 to version 6.0.
Workaround: Create a new report and view from there.
•CSCsz96466—If you create a WLAN with webauth security, create a guest user mapped to the WLAN, and then forward it to WLC, you cannot delete the WLAN on the Configure > Controller > WLAN page. An exception error is returned.
Workaround: Delete the guest user associated to the WLAN. You can then delete the WLAN without any exception.
•CSCsz96510—If you try to delete a WLAN with a mobility anchor configured, an unknown exception is returned.
Workaround: Disassociate the mobility anchor on the WLAN page.
•CSCsz96549—When a guest user with limited liftetime is discovered from a Discover Templates from Controller function, the wrong expire and end time is shown.
Workaround: Create the guest user from the wcs-guest user template rather than using Discover Templates from Controller.
•CSCta00548—From version 4.2 to 6.0, all web auth configuration (including internal, external, and customized) returns an SNMP failure across all supported controllers.
Workaround: Configure all web auth from the web GUI. Or do not leave URLs blank when you configure a webauth template. Enter data in the customized and external webauth URLs by changing to different webauth types.
•CSCta02499—On the Summary > Controller page, WCS incorrectly shows the remaining period of an evaluation license for 5500 series controllers.
Workaround: The Administration > License Center > Controllers > Files window shows the correct information.
•CSCta04203—WCS sometimes fails to display clients in a partition that contains the access point to which the client is associated but which does not contain the controller to which the access point is associated.
Workaround: Add the controller to the partition.
•CSCta05459—WCS creates a guest user template and a local net user for the same config when a guest user that was created on a controller performs a refresh config.
Workaround: Create the guest user from WCS rather than from the controller.
•CSCta05909—WCS fails to perform a View History for a guest count graph.
Workaround: You can use the guest count graph to see week, month, and year.
•CSCta08270—WCS does not allow email addresses with more than 32 characters.
•CSCta18874—In some Windows installations in locales outside of the U.S., WCS startup fails.
Workaround: Modify the WCS_Install_Directory\bin\startServer.bat file. Change set MAX_HEAP_SIZE=m to set MAX_HEAP_SIZE=1024m.

This error occurs if extra or missing standard signatures exist 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.
•CSCsm99598—A blank page appears when the ID certificate is downloaded from Configure > Controller > Security > ID Certificate. The certificate download is unsuccessful.

•CSCsq17846—An error is received if you download software on a WLC using WCS regardless of whether you use FTP, TFTP, or the GUI. This error occurs only if the access point is already downloading software from the WLC.
Workaround: Use the WLC GUI to get a better error message.
•CSCsq34438—WCS shows wrong values for channel and client profiles with OFDM.
Workaround: You can reference the WLC because it shows the values correctly.
•CSCsq35574—The EAP-FAST parameters Authority ID and Server Key do not accept entries of 17 or more characters.
•CSCsq38486—The profile VLAN mapping is not updated correctly on the access point, even though the native VLAN is applied correctly.
Workaround: Configure the hybrid REAP configuration with native VLAN and forward it to the access point. The native VLAN is correctly applied. Change the profile name on the same native VLAN and forward the mapping to the access point. The profile name VLAN mapping is correctly applied. It can also be applied from the WLC UI.
•CSCsr68574—If WCS shows a mismatch of values between WLC and WCS and the Restore WCS Values to Controller option is chosen, the stored configuration does not successfully pass to the controller.
•CSCsu39828—Even if activity for an infrastructure client is no longer occurring, the client still remains on the WCS map.
•CSCsz28308—Config group template and audit consistently display a mismatch even when the config template is updated from the controller.
•CSCsz39198—An unknown exception appears when running Generate Proposal. If the image size is more than 16 Mega Pixels (on a Windows platform) an exception may get thrown due to a JVM bug (the JVM runs out of memory).
•Workaround: Open the image in an image editor and reduce the size of the image. The best supported size is approximately 12 Mega Pixels.
•CSCsz91711—The copy and replace function does not copy information (such as host name and IP address) to the WLC.
•CSCsz95770-—When you choose Monitor > Alarms and view the interference alarm detail, it is missing information for the top 5 access points, some exceptions are returned, and some values are not correct.
Workaround: Look in Monitor > Event to view alarm details.
•CSCsz95961—The Voice Parameter template fails when it is applied to controllers.
•CSCsz96528—The Mesh AP Detail page (Configure > Access Point and open Mesh access point) displays with an error message.
Workaround: Try accessing the page with Firefox. Only Internet Explorer 6 and 7 have the issue.
