Upgrading Cisco WCS

This section provides instructions for upgrading Cisco WCS on either a Windows or Linux server. It handles the steps you would normally follow to accomplish a manual upgrade (shut down Cisco WCS, perform a backup, remove the old Cisco WCS version, install the new version, restore the backup, and start Cisco WCS). If you choose to use the installer, it searches for any previous Cisco WCS versions.


Note You must have software release 4.1.91.0 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 that causes an exit occurs. An upgrade-version.log is also produced and provides corrective measures.


Note For steps on upgrading Cisco WCS in a high availability environment, see Chapter 14, "Performing Maintenance Operations" of the Cisco Wireless Control System Configuration Guide.


Using the Installer to Upgrade Cisco WCS for Windows

To upgrade Cisco WCS (on a Windows platform) using the automated upgrade, follow these steps:


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-K9-6-0-X-Y.exe file that you downloaded to your local drive. 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.

Step 2 Click the I accept the terms of the License Agreement option to continue. At this point, the install wizard detects whether a previous version of Cisco WCS is installed and specifies whether the current version is eligible for an automated upgrade. If your Cisco WCS version cannot participate in the automated upgrade, you receive such a notice.

Step 3 If your Cisco WCS version is eligible for an automated upgrade and the previous qualifying version of Cisco WCS is detected, choose Upgrade and continue to Step 4. This method is preferred. If your Cisco WCS version is ineligible for an automated upgrade, choose Install to end the installer and switch to a manual upgrade. (See the Cisco Wireless Control System Configuration Guide for manual upgrade instructions.)

Several of the values from the previous installation are retained as part of the upgrade. These include the following:

The ports

The root password

The root FTP password

The TFTP server file location

The FTP server file location

The multi-homed server interfaces

Step 4 In the Choose Install Folder page, 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 5 Choose a folder location in which to store the shortcuts. It must be a different location than the previous installation.


Note If shortcuts should be installed for all users on the server, select the Install shortcuts for all users check box.


Step 6 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 Cisco 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 Cisco WCS is configured to use TACACS+ or RADIUS for external authentication, you must update the custom vendor attribute list in the TACACS+ or RADIUS server with any new permissions and virtual-domain information. The attribute list for the appropriate UserGroup can be found at Administration > AAA > UserGroups. Click the Export link for the appropriate user group. See Chapter 14 "Performing Maintenance Operations" of the Cisco Wireless Control System Configuration Guide for additional information regarding upgrading.



Using the Installer to Upgrade Cisco WCS for Linux

To upgrade Cisco WCS (on a Linux platform) using the automated upgrade, follow these steps:


Step 1 Using the command-line interface, 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 or Cisco.com users) to start the install script. The Install Anywhere message appears and prepares the system for installation. After a few seconds, the Introduction appears, followed by the license agreement statement.

Step 3 Accept the license agreement to continue.

At this point, the install wizard detects whether a previous version of Cisco 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 Cisco WCS version is eligible for the automated upgrade.

Step 4 If your Cisco WCS version is eligible for an automated upgrade and the previous qualifying version of Cisco WCS is detected, choose Upgrade and continue to Step 6. This method is preferred. If your Cisco WCS version is ineligible for an automated upgrade, choose Install to end the installer and switch to a manual upgrade. (See the Cisco Wireless Control System Configuration Guide for manual upgrade instructions.)

Several of the values from the previous installation are retained and carried over as part of the upgrade. These include the following:

The ports

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. It must be a different location than the previous installation. Click Next to continue.

Step 6 Choose a folder location 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 Cisco 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 Cisco 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. See Chapter 14, "Performing Maintenance Operations" of the Cisco Wireless Control System Configuration Guide for additional information regarding upgrading.



Restoring the Cisco WCS Database in a High Availability Environment

During installation, you are prompted to determine if a secondary Cisco WCS server would be used for high availability support to the primary Cisco WCS server. If you opted for this high availability environment and enabled it in the Administration > High Availability page, 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.


Choose the desired option from the following choices to change the status from HA enabled to HA not configured:

Click Remove in the HA Configuration page (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 a failover has not been executed, so the secondary server is in the SecondaryLostPrimary state.

The primary server is down and a 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.


Important Notes

This section describes important information about Cisco WCS.

If you change the report repository path under Administration > Settings > Report, then the existing saved download report will no longer work. To fix this problem, manually move the files to the new directory by cutting and pasting the files.

If you are upgrading between different releases of the WCS and Controller, check the SNMP MIBs or OID structures on running controller versions for affected changes of features. Controller should be applying commands based on right MIB versions.

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.

High Availability

An e-mail address is now optional when you configure high availability. However, if you enter a properly formatted e-mail address, you must also configure a Cisco WCS e-mail server.


Note High availability is supported on Linux, Windows 2003, and 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 on 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 the upgrade. The new client detail report contains the details of association time, disassociation time, and session timeout 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 E-mail Folder

If a domain name is not set in the e-mail settings, notifications may end up in the junk e-mail. When the primary device is down, no e-mail notifications are received, but the log message indicates that an e-mail was successfully sent.

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 deregistered the dynamic-link library (DLLs). Reregistering them corrects the problem.

To reregister the DLLs, follow these steps:


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 behavior is expected.

Also, if you visit the AP Details page 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, choose Configure > Controller Templates, choose TFTP server from the left sidebar menu, and choose Add TFTP Server from the drop-down list. 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 page when only the default server appears.

Conflicting Ports Interrupt Cisco WCS Start

Cisco 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 Cisco WCS requires.

New Features

There are no new features in this maintenance release.
