WAAS Mobile Product Overview
Cisco Wide Area Application Services (WAAS) Mobile provides significant application acceleration and bandwidth savings to telecommuters, mobile users, and home-office users accessing corporate HTTP applications, e-mail, and file servers.
By default, Cisco WAAS Mobile accelerates a range of applications including most web browsers, email clients, Windows Explorer for file shares, FTP clients, and thin clients like Citrix and Microsoft Remote Desktop Client (RDC). In addition, any generic application using TCP connections to content servers can be added through its process name. This list of accelerated applications is determined by comparing the name of the process running on the end user's machine to a pre-configured list of "Accelerated Processes." TCP connections associated with processes not in this list will be "bypassed."

Upgrading From or Downgrading to a Previous Version
This section contains information on how to upgrade from and downgrade to previous software versions.
•Upgrading from Version 3.5.0 or 3.5.1
•Upgrading from Version 3.4.x or Earlier Versions
•Upgrading From a Version Prior to 3.3.1342.4
•Downgrading to an Earlier Version of Software
Upgrading from Version 3.5.0 or 3.5.1
Perform the following procedure if you are upgrading to version 3.5.2 from either version 3.5.0 or 3.5.1.
Step 1 Prior to upgrading:
•Verify that Automatic Upgrades are enabled on the Configure > Clients > Software page of the Manager.
•Backup the system configuration using the Manage > Backup and Restore page of the Manager.
Step 2 Stop all servers.
Step 3 Uninstall the previous version of WAAS Mobile server software and, during the uninstall process, select the option to retain all configuration information.
Step 4 Install the new version of WAAS Mobile Manager on the server machine by double-clicking the ServerSetup.exe file and then rebooting if prompted.
Step 5 Start all servers.
Step 6 Navigate to the Configure > Apply Settings page of the Manager and apply settings. The clients will now be automatically upgraded to version 3.5.2.
Upgrading from Version 3.4.x or Earlier Versions
Upgrading from a version earlier than 3.5.0 includes a major upgrade to the WAAS Mobile management infrastructure and introduces enhanced mechanisms and policies for managing clients and servers. As a result of these changes, it will be necessary to reconfigure the WAAS Mobile Manager after upgrading.
Step 1 Prior to upgrading:
a. Record the current configuration settings.
Note All client and server configurations will be deleted during the upgrade process and will need to be re-entered after Release 3.5.2 is installed. Please be sure to record existing configuration information, including the names of all fielded client distribution profiles. Additionally, export the system configurations by navigating to the Server Configuration tab and selecting the Import/Export menu item, and then pressing the Export button. The configuration will be exported into an XML file that can be used as a reference if needed.
b. If you are currently running the WAAS Mobile server on a 32-bit version of the Windows Server Operating System, consider upgrading the Windows Operating System to a 64-bit version for improved scalability and performance.
c. If you are currently using the IP aliasing feature, perform the following steps before uninstalling 3.5.0:
•Turn off IP Aliasing.
•Reboot the server and confirm that no aliased IP addresses exist on the NIC card by typing ipconfig /all in the command line.
d. Uninstall the previous version of WAAS Mobile server software and, during the uninstall process, select the option to remove all configuration information.
Step 2 Install the new version of WAAS Mobile Manager on the server machine by double-clicking the ServerSetup.exe file and then rebooting if prompted.
Step 3 Login to the WAAS Mobile Manager using the following default credentials:
–Username: admin
–Password: default
Step 4 Configure the Manager, Server(s) and Clients, following the guidance in Chapters 5, 6, and 7 of the Cisco WAAS Mobile Administration Guide and apply configurations when complete.
Note Recreate the client distributions using the same names that were previously used to ensure that when the WAAS Mobile servers are started, the client software and configurations will be automatically updated.
Note The system configuration that was exported from Release 3.4 cannot be automatically inputted. The configurations must be entered via the GUI.
Step 5 Verify that:
a. If more than one server is deployed, all servers are managed centrally.
b. All servers are assigned to a server profile, which defines the configuration policies for those servers
c. All servers are assigned to a server farm, which associates them with the networks that they will accelerate and provisions load balancing and failover, when appropriate.
d. All previously existing client distributions have been re-created. The quickest approach is to configure a single client distribution fully and then use the copy feature to generate the other distributions.
e. All processes that were previously configured on the HTTP and HTTPS accelerated processes list have been configured.
f. Delta cache size and location is correctly specified.
Step 6 From the Manage > Servers page of the WAAS Mobile Manager, verify that all servers are properly addressed and have licenses and then start the servers that are not running.
Step 7 When the server upgrade completes and the servers are restarted, the WAAS Mobile clients on the users' PCs will automatically download the new software and configurations and, at the conclusion of the client software upgrade, the users will be prompted to reboot. Acceleration will be disabled (indicated by the gray icon) until the reboot occurs; at that time, the client will reconnect and begin accelerating, and the icon will turn green.
Upgrading From a Version Prior to 3.3.1342.4
When upgrading from any version of WAAS Mobile prior to version 3.3.1342.4, you must completely uninstall both the client and the server software. See the Cisco WAAS Mobile Administration Guide for a detailed description of install and uninstall procedures.
Downgrading to an Earlier Version of Software
To downgrade from version 3.5.2 to version 3.5.1 (or from version 3.5.2 to version 3.5.0), perform the following steps on the server:
Step 1 Before downgrading, on the Upgrades tab of the Configure > Clients > Software page, select Enable Automatic Downgrades.
Step 2 Uninstall version 3.5.2 and then re-install version 3.5.1 or 3.5.0.
Step 3 Restart the server.
To downgrade to a version prior to 3.5.0, you must completely uninstall both the client software installation and the server installation. See the Cisco WAAS Mobile Administration Guide for a detailed description of install and uninstall procedures. After downgrading, configurations will need to be manually re-entered.
New and Changed Features
Management Enhancements
•WAAS Mobile Manager GUI pages depicting client and server statistics no longer render slowly.
•Automatic software downgrade functionality, which was dropped in Release 3.5.0, has been added back into the product.
•Ability to view past session data, which was dropped in Release 3.5.0, has been added back into the product.
•Enhanced input validation to reject entry of client distribution names that contain spaces, as spaces are not allowed in the name.
Operating Considerations
Operating considerations include the following categories:
•Interoperability Considerations
•Acceleration Performance Considerations
•Management Considerations
Interoperability Considerations
•Cisco WAAS Mobile Manager should not be installed on a Windows Domain Controller.
•Cisco WAAS Mobile Manager requires that the inetpub directory be configured on the C: drive.
•When interoperating with the CheckPoint IPsec or Microsoft Intelligent Application Gateway (IAG) VPN clients, the network monitoring feature on the client should not be enabled. Note that this feature is disabled by default.
Acceleration Performance Considerations
•The Cisco WAAS Mobile client will not function if the user logs in using Microsoft Windows Guest accounts.
•Cisco WAAS Mobile will only accelerate the first user that logs into a computer. For example, if a user is logged-in locally, and another user logs into the same machine via remote terminal services, only the local user's sessions will be accelerated. Also, if Fast User Switching is used, only the sessions associated with the user that logged-in first will be accelerated.
•Transparent CIFS SMB does not support the persistent sessions feature. Connections opened via transparent CIFS SMB will not be maintained when a short network outage occurs.
•When using Outlook 2007 with Exchange 2007, the Meeting Room Request feature is not supported. Workaround: Please contact TAC for configuration instructions that will disable application protocol optimization while continuing to provide data reduction and transport optimization.
•The WAAS Mobile client should be enabled and running before initiating SMB sessions between Windows 7 and Vista clients and Windows Server 2008 or 2008 R2 file shares in order to achieve optimum acceleration of this traffic.
•In some cases, CIFS SMB traffic between PCs running Windows 7 or Vista PCs and file servers running Windows Server 2008 or 2008 R2 may not receive protocol optimization. Workaround: Configure these PCs for SMB 1.0 compatibility mode by setting the following registry key:
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters Smb2 (DWORD) = 0.
•When optimizing the CIFS protocol when SMB signing is required, users may be prompted to enter credentials the first time they access the file share after WAAS Mobile has been installed or upgraded.
Management Considerations
•The WAAS Mobile Manager statistics for client sessions may not match client-side statistics, as the WAAS Mobile Manager is updated less frequently than the WAAS Mobile client.
•WAAS Mobile Manager may incorrectly report a failure to start when, in fact, WAAS Mobile did start. When this occurs, the Windows Service Control Manager displays a message that states "At least one service or driver failed during system startup. Use Event Viewer to examine the event log for details." When the Event Viewer's system log is viewed, it will indicate the following error message "The WAAS Mobile Manager service hung on starting." These messages should be ignored.
•Some pages of the Manager GUI may not render well with Internet Explorer 6.0 or 7.0. Workaround: Upgrade to Internet Explorer 8 or later or use the Firefox browser.
•When using SNMP to manage WAAS Mobile servers, the dll must be manually registered as follows:
a. Open the Windows command prompt.
b. Type "cd c:\Program Files\Cisco Systems\WAASMobileServer".
c. Type "rundll32.exe AccelSnmpXa.dll, DllRegisterServer".
d. Reboot.
Resolved Caveats in Software Version 3.5.2
The following caveats have been resolved in software version 3.5.2.
Management Caveats
•CSCth45755—In some cases, when a client session is connected, the Manager properly indicates that the client is connected but then if you click on the user entry it says "not connected."
•CSCtf94499—The WAAS Mobile Manager's Manage > Servers page status no longer occasionally fails to update after starting or stopping a server.
•CSCtf94538—The WAAS Mobile Manager's statistics database import feature now works properly on Windows Server 2008 and later OSs.
•CSCth06976—The order of the OK/Cancel buttons has been fixed in two dialogs in order to be consistent with common usage.
•CSCth06920—Cancel button added to the Add/Edit Server dialog.
•CSCth15745—Monitoring statistics are now displaying properly in the GUI when server is running on European version of the Windows OS and CPU usage is normal.
•CSCth06981—The pagination on the HTTPS tab on the Clients > Acceleration page has been fixed.
•CSCtk05941—Issue associated with configuring hostnames for the WAAS Mobile server that provides the client with a license has been resolved.
•CSCti86052—Can now change server IPs or hostname on client distributions dynamically.
•CSCto78623—Can now configure a client distribution to use a hostname which resolves to more than one IP address.
•CSCtj28542—Group policy Active Directory template files now employ a .txt extension for ease of download.
•CSCtj54702—Group policy Active Directory templates are now also generated for 64-bit OSs.
•CSCto78763—Group policy Active Directory template file data entry for configuring the address that the client should connect to has been fixed.
•CSCtj59888—WAAS Mobile Server was not closing acceleration sessions properly, which occasionally resulted in more licenses being consumed that the number of users connected. This issue has been fixed.
•CSCtk55519—System reports now consistently upload to the server.
•CSCto80432—If IIS permissions were not correctly set, WAAS Mobile Manager would not be accessible and report that the Access Control List is not in a canonical form. Software has been enhanced to detect and auto-repair this issue.
•CSCto80455—WAAS Mobile Manager service now exits gracefully and auto-restarts on error.
WAAS Mobile Client Caveats
•CSCtg01881—The accuracy of the latency and bandwidth displayed on the Accelerated Server Connections tab in the Client GUI has been corrected.
Acceleration Caveats
•CSCti00627—The generic optimization parameter settings on the Configure > Clients > Acceleration page are now correctly applied.
•CSCtj73132—Issue with slow acceleration of Windows 7 clients accessing mapped drives has been resolved.
•CSCtj28710—When group policy associated with NTLMv2 authentication was setting the "Network Security: LAN Manager authentication level" and was over-riding the default policy on file shares, CIFS optimization was not properly obtaining the session key, which resulted in an inability to accelerate those file shares. This issue has been resolved.
•CSCtk11189—Disabling SMB acceleration no longer affects the acceleration of other traffic.
•CSCto47536—PST access issues may result in PST files disappearing from the outlook client or problems occurring when trying to move files to PST folders. This behavior is due to EMC Celerra server and WM server SMB incompatibility with Read Andx Requests.
•CSCto80488—Windows 7, prior to Service Pack 1, improperly truncates process names, resulting in interoperability issues with applications such as Trend Micro Titanium. WAAS Mobile now sends the client driver both truncated and full names so that this OS issue does not affect acceleration performance.
•CSCto80516—The file size of an HTTP download is no longer limited to 2 GB.
•CSCto80530—When dynamic bandwidth allocation for VoIP is configured, a clearer message is now provided in the client GUI's TCP sub-tab on the Diagnostic Tab. Specifically, the status of these TCP connections is now identified as "Bypassed: VOIP Monitoring Only."
•CSCto80546—The database session cleanup error reported in the WAAS Mobile Manager server logs has been fixed.
Interoperability Caveats
•CSCth63047—When there are duplicate entries on the TDI Group Order List, the WAAS Mobile Client driver will now install properly.
Open Caveats in Software Version 3.5.2
The following caveats are open in software version 3.5.2.
Installation caveats
•CSCtf99067—ASP.Net must be pre-installed on the Windows Server 2008 R2 Operating System before WAAS Mobile may be installed.
Management caveats
•CSCth93291—In some cases, after a license expires and a new license is entered, the WAAS Mobile Manager fails to restart. Workaround: Restart the ControllerService after applying the new license key.
•CSCth06923—DBCS characters, such as those used for Japanese characters, are not supported by WAAS Mobile, resulting in the following issues:
–Client system report transmission fails if Windows Login name contains DBCS.
–Japanese text is garbled in the description field of a System Report.
–Client log entries in the Event Log show nothing if c_working.log contains DBCS characters in path name.
–If DBCS characters are entered, the field value cleared without notification and the value isn't used.
–OK and Cancel buttons disappear from "Editing Server Profile" dialog if DBCS characters are entered in the Profile field.
–DBCS text sent in a message to a user is garbled.
•CSCtf99087—Refresh button does not work on some WAAS Mobile Manager pages. Workaround: Manually refresh the page.
•CSCtf94618—If the WAAS Mobile Manager password is updated while a worker server is offline, the worker server will not authenticate with the WAAS Mobile Manager when it is brought back online and hence, will not manage that server. Workaround: Manually update the password on the worker server by changing it's management authority to be locally managed and then entering the new password. Once the updated password has been entered, reconfigure the worker server to be managed by the WAAS Mobile Manager.
•CSCtf94635—When the WAAS Mobile Manager is configured to send email alerts notifying an administrator that a system report has been generated, the system report for only one of the worker servers associated with the event is listed in the email. Workaround: The other system reports are posted on the Manage > System Reports page of the WAAS Mobile Manager.
•CSCtl07227—If PCs are cloned, connected clients may not displayed on the Manage > Clients page. Workaround: Use client registration to ensure that unique client names are used.
Acceleration caveats
•CSCte79110—CIFS protocol optimization does not support the use of the "<" unicode wildcard.
