Cisco WAAS Appliance System Firmware Update

On Cisco Wide Area Application Engine (WAE) and Cisco Wide Area Application Virtualization Engine (WAVE) appliances, we recommend that you update the following three types of system firmware to the latest version to best support new Cisco WAAS features:

BIOS on the WAVE-294/594/694/7541/7571/8541 models—For details, see the "BIOS Update" section. The latest BIOS is required for AppNav operation.

BMC firmware on the WAVE-294/594/694/7541/7571/8541 models—For details, see the "BMC Firmware Update" section. The latest Baseboard Management Controller (BMC) firmware is required for Intelligent Platform Management Interface (IPMI) over LAN feature.

RAID controller firmware on the WAE-674/7341/7371 and WAVE-7541/7571/8541—For details, see the "RAID Controller Firmware Update" section. The latest Redundant Array of Independent Disks (RAID) controller firmware is recommended to avoid some rarely encountered RAID controller issues.

BIOS Update

The latest BIOS is required for AppNav operation with a Cisco AppNav Controller Interface Module in WAVE-594/694/7541/7571/8541 models. WAVE-294 models may also need a BIOS update, though they do not support AppNav.

WAVE-594/694/7541/7571/8541 appliances shipped from the factory with Cisco WAAS Version 5.0.1 or later have the correct BIOS installed. WAVE-294 appliances shipped from the factory with Cisco WAAS Version 5.1.1 or later have the correct BIOS installed.

If you are updating a device that was shipped with an earlier version of Cisco WAAS software, you should update the BIOS, unless it was updated previously. WAVE-594/694 models require BIOS version 18A, WAVE-7541/7571/8541 models require BIOS version 11A, and WAVE-294 models require BIOS version 18A.

If you install a Cisco AppNav Controller Interface Module in a device that requires a BIOS update, the bios_support_seiom major alarm is raised, "I/O module may not get the best I/O performance with the installed version of the system BIOS firmware."

To determine if a device has the correct BIOS version, use the show hardware command. The following example displays the BIOS version installed on the device, which is the last three digits of the version value:

wave# show hardware
.
.
.
WAVE-594-K9
 
   
BIOS Information:
Vendor         :American Megatrends Inc.
Version        :A31C117A                         <<<<< version 17A
Rel. Date      :02/24/2012
.
.
.
 
   

If a BIOS firmware update is needed, you can download it from cisco.com at the Cisco Wide Area Application Service (WAAS) Firmware download page (registered customers only). The firmware binary image for WAVE-294/594/694/7541/7571/8541 appliances is named waas-bios-installer-18a-18a-11a-k9.bin.

You can use the following command to update the BIOS from the image file that is available through FTP on your network:

copy ftp install ip-address remotefiledir waas-bios-installer-18a-18a-11a-k9.bin

Use the appropriate BIOS installer file for your appliance model.

The complete update process can take several minutes and the device may appear unresponsive but do not interrupt the process or power cycle the device. After the update is complete, you must reload the device.

After the device reboots, you can verify the firmware version by using the show hardware command.

BMC Firmware Update

IPMI over LAN requires that you install a specific BMC firmware version on the device. The minimum supported BMC firmware versions are as follows:

WAVE-294/594/694—49a

WAVE-7541/7571/8541—27a

Cisco WAAS appliances shipped from the factory with Cisco WAAS Version 4.4.5 or later have the correct firmware installed. If you are updating a device that was shipped with an earlier version of Cisco WAAS software, you must update the BMC firmware, unless it was updated previously.

To determine if you are running the correct firmware version, use the show bmc info command. The following example displays the latest BMC firmware version installed on the device (49a here):

wave# show bmc info
Device ID                 : 32
Device Revision           : 1
Firmware Revision         : 0.49                    <<<<< version 49

If a BMC firmware update is needed, you can download it from cisco.com at the Cisco Wide Area Application Service (WAAS) Firmware download page (registered customers only). For example, if the firmware binary image is named waas-bmc-installer-48a-48a-27a-k9.bin, you can use the following command to update the firmware from the image file that is available through FTP on your network:

copy ftp install ip-address remotefiledir waas-bmc-installer-48a-48a-27a-k9.bin

The update process automatically checks the health status of the BMC firmware. If the system detects that the BMC firmware is corrupted, BMC is recovered during the BMC firmware update procedure. The complete update process can take several minutes. If the device appears unresponsive, do not interrupt the process or power cycle the device. After the update is complete, you must reload the device.

After the device reboots, you can verify the firmware version by using the show bmc info command.

BMC recovery and BMC firmware update restores the factory defaults on the BMC and all the current IPMI over LAN configurations are erased.

If the BMC firmware gets corrupted, a critical alarm is raised.

RAID Controller Firmware Update

We recommend that you upgrade to the latest RAID controller firmware for your hardware platform, which can be found on cisco.com at the Cisco Wide Area Application Service (WAAS) Firmware download page (registered customers only). The firmware differs depending on your hardware platform:

WAVE-7541/7571/8541—Update to the 12.12.0 (0060) RAID Controller Firmware (or later version).

The firmware binary image is named waas-raid-fw-installer-12.12.0-0060-k9.bin. Instructions on how to apply the firmware update are posted on cisco.com together with the firmware in the file named M2_0060_FIRMWARE.pdf, which you can see when you mouse over the firmware file.

WAE-674/7341/7371—Update to the 5.2-0 (17002) RAID Controller Firmware (or later version). You can check your current RAID controller firmware version with the show disk tech-support EXEC command. The Firmware field displays the firmware version.

The firmware binary image is named L4_xxxxx_FIRMWARE.bin. Instructions on how to apply the firmware update are posted on cisco.com together with the firmware in the file named L4_xxxxx_FIRMWARE.pdf, which you can see when you mouse over the firmware file.

Under rare circumstances, the RAID controller firmware used in the WAE-674, WAE-7341, and WAE-7371 appliances can cause the disk storage subsystem to go offline and the affected devices to stop optimizing connections. The symptoms are as follows:

Syslog output contains several instances of the following message:
"WAAS-SYS-3-900000: sd 0:0:0:0: rejecting I/O to offline device."

A sysreport and running-config file cannot be generated and copied to /local/local1.

Both these symptoms are an indication of the file system becoming read-only during traffic flow.

An increasing number of pending connections appear in the output of the show statistics tfo command, which indicates that new connections cannot be optimized. You can use this command to proactively check the functionality of the system.

The solution is to upgrade to the 5.2-0 (17002) RAID Controller Firmware (or later version).

Interoperability and Support

Table 1 lists the hardware, client, and web browser support for Cisco WAAS Software Version 5.3.1.

Table 1 Hardware, CIFS Client, Web Browser Support 

Hardware support

The Cisco WAAS software operates on these hardware platforms: WAE-674, WAE-7341, WAE-7371, WAVE-274, WAVE-474, WAVE-574, WAVE-294, WAVE-594, WAVE-694, WAVE-7541, WAVE-7571, or WAVE-8541 appliance, or an SM-SRE-700, SM-SRE-710, SM-SRE-900, or SM-SRE-910 network module that is installed in specific Cisco routers. Additionally, Cisco 880 Series, 890 Series, and ISR G2 routers running Cisco WAAS Express are supported on the branch side (Cisco WAAS Version 4.2.1 or later is required on the data center side). vWAAS is supported in a Kernel Virtual Machine (KVM) on the Cisco 4451-X Integrated Services Router and on a UCS E-Series module installed in a Cisco ISR G2 or Cisco 4451-X Integrated Services Router, and on other supported VMware virtual machines (for details, see the Cisco Wide Area Application Services vWAAS Installation and Configuration Guide).
You must deploy the Cisco WAAS Central Manager on a dedicated device.

Note Cisco WAAS, Release 5.3 is the final version that will support the WAE-674, WAE-7341, WAE-7371, WAVE-274, WAVE-474, and WAVE-574 platforms.

CIFS client support

The Cisco WAAS software running on a branch WAE interoperates with these Common Internet File System (CIFS) clients: Windows 98/NT 4.0/2000/XP/Vista/7 and Windows Server 2003/2008 R2.

Web browser support

The Cisco WAAS Central Manager GUI requires Internet Explorer version 8 or 9 (only 8 on Windows XP), Firefox version 4 or later, Chrome version 10 or later, or Safari version 5.x (only on Apple OS X) and the Adobe Flash Player browser plug-in. The WAE Device Manager GUI requires Internet Explorer version 5.5 or later.


If you are using Internet Explorer to access the Central Manager GUI, we strongly recommend that you install the Google Chrome Frame plug-in to provide better performance. When you log in to the Central Manager the first time, you are prompted to install Google Chrome Frame. Choose a language, click Get Google Chrome Frame, and follow the prompts to download and install the plug-in. If you do not want to install the plug-in, click the link to continue without installing Google Chrome Frame.


Note When using Internet Explorer, ensure that the Tools > Internet Options > Advanced tab > Do not save encrypted pages to disk check box (under Security) is checked. If this box is unchecked, some charts do not display (CIFS device level charts and version 4.x scheduled reports that have completed). Additionally, we recommend that you clear the browser cache and restart the browser if CIFS device level charts are not visible.


Cisco WAAS Version Interoperability

Consider the following guidelines when operating a Cisco WAAS network that mixes Software Version 5.3.1 devices with devices running earlier software versions:

Cisco WAAS Version 5.3.1 is not supported running in a mixed version Cisco WAAS network where any Cisco WAAS device is running a software version earlier than 4.2.1. If you have any Cisco WAAS devices running a version earlier than 4.2.1, you must first upgrade them to version 4.2.1 (or a later version) before you install Version 5.3.1. Do not upgrade any device to a version later than the existing Central Manager version. After all devices and the Central Manager are running version 4.2.1 or later, you can begin the upgrade to Version 5.3.1 on the Central Manager. Directly upgrading a device from Version 4.0, 4.1, or 4.2 to 5.3.1 is not supported.

In a mixed version Cisco WAAS network, the Central Manager must be running the highest version of the Cisco WAAS software.

AppNav Interoperability

Consider the following guidelines when deploying the Cisco AppNav solution:

If you are connecting an AppNav Controller (ANC) to a Catalyst 6500 series switch and you have configured the ANC to use the Web Cache Communication Protocol (WCCP) with the L2 redirect method, do not deploy the ANC on the same subnet as the client computers. This configuration can cause packet loss due to a limitation of the Catalyst 6500 series switch.

All Cisco WAAS nodes in an AppNav deployment must be running Cisco WAAS version 5.0 or later.

Cisco WAAS Express devices cannot operate as Cisco WAAS nodes in an AppNav deployment.

A software version of AppNav, called AppNav-XE, is available on Cisco routers that run Cisco IOS XE Release 3.8 and later but it is not interoperable with Cisco AppNav Controller Interface Modules in the same AppNav Controller group. AppNav-XE can redirect traffic to Cisco WAAS devices for optimization.

Cisco WAAS Express Interoperability

Consider the following guideline when using Cisco WAAS Express devices in your Cisco WAAS network:

When using a Cisco WAAS device running version 5.x and a Cisco WAAS Express peer device running Cisco IOS Release 15.2(2)T or earlier, connections originating from the Cisco WAAS device and sent to the Cisco WAAS Express peer are passed through instead of being optimized. We recommend upgrading to Cisco WAAS Express in Cisco IOS Release 15.2(3)T or later to take advantage of the latest enhancements


Note As listed in "Software Version 5.1.1 Open Caveats," CSCug16298, "WAAS-X to WAAS 5.1.1 connections will be reset when using HTTP acceleration." We recommend that you do not use HTTP Application Optimizer (AO) between Cisco WAAS and Cisco WAAS Express unless you are running Cisco IOS Release 15.3(1)T or later.


WCCP Interoperability

Central Managers running Version 5.3.1x can manage WAEs running software Versions 4.2.1 and later. However, we recommend that all WAEs in a given WCCP service group be running the same version.


Note All WAEs in a WCCP service group must have the same mask.


To upgrade the WAEs in your WCCP service group, follow these steps:


Step 1 You must disable WCCP redirection on the Cisco IOS router first. To remove the global WCCP configuration, use the following no ip wccp global configuration commands:

Router(config)# no ip wccp 61
Router(config)# no ip wccp 62
 
   

Step 2 Perform the Cisco WAAS software upgrade on all WAEs using the Cisco WAAS Central Manager GUI.

Step 3 Verify that all WAEs have been upgraded in the Devices pane of the Central Manager GUI. Choose Devices to view the software version of each WAE.

Step 4 If mask assignment is used for WCCP, ensure that all WAEs in the service group are using the same WCCP mask value.

Step 5 Reenable WCCP redirection on the Cisco IOS routers. To enable WCCP redirection, use the ip wccp global configuration commands:

Router(config)# ip wccp 61
Router(config)# ip wccp 62
 
   

NTLM Interoperability

Cisco WAAS Version 5.1 and later do not support Windows domain login authentication using the NTLM protocol. Therefore, upgrading from a Cisco WAAS Version earlier than 5.1 with the device configured with Windows domain login authentication using the NTLM protocol is blocked. You must change the Windows domain authentication configuration to use the Kerberos protocol before proceeding with the upgrade.

Follow these steps to change from NTLM to Kerberos Windows domain login authentication:


Step 1 Unconfigure Windows domain login authentication. You can do this from the Central manager in the Configure > Security > AAA > Authentication Methods window.

Step 2 Change the Windows domain configuration setting to use the Kerberos protocol. You can do this from Central manager in the Configure > Security > Windows Domain > Domain Settings window. For more information, see the section "Configuring Windows Domain Server Authentication Settings" in the "Configuring Administrative Login Authentication, Authorization, and Accounting" chapter of the Cisco Wide Area Application Services Configuration Guide.

Step 3 Perform the Windows domain join again from the Central manager in the Configure > Security > Windows Domain > Domain Settings window.

Step 4 Configure Windows domain login authentication from the Central manager in the Configure > Security > AAA > Authentication Methods window.

Step 5 Upgrade your device.


Note If you are upgrading the Central Manager itself from the GUI and the Windows domain login authentication on the Central Manager is configured to use the NTLM protocol, the upgrade fails with the following error logged in the device log:
Error code107: The software update failed due to unknown reason. Please contact Cisco TAC.

To view the device log for the Central Manager, choose the Central Manager device and then choose Admin > Logs > Device Logs. If you see this error, follow the steps above to change the Central Manager device Windows domain login authentication from NTLM to Kerberos.

If you upgrade the Central Manager itself from the CLI and the upgrade fails due to NTLM being configured, you will get an appropriate error message. Once the Central Manager is upgraded to Version 5.1, it can detect and display the reason for any upgrade failures for other devices.




Note Cisco WAAS Version 5.1 and later do not support the Kerberos protocol running with a nonstandard port (other than port 88). Upgrading from a Cisco WAAS Version earlier than 5.1 with the device configured with the Kerberos protocol on a nonstandard port is blocked. You must change the Kerberos server on your network to listen on port 88 and change the Kerberos configuration on the device to use port 88. You can do this from the Central manager in the Configure > Security > Windows Domain > Domain Settings window.


If you are trying to upgrade your device from the CLI and the upgrade fails due to NTLM configuration, then the kerberos_validation.sh script is installed on your device. This script can be used to verify that your network supports the Kerberos protocol before changing from NTLM to Kerberos. This script is not available if you are using the Central Manager to upgrade the device.

To run the script, follow these steps:


Step 1 (Optional) Run the Kerberos validation script command with the -help option to display the usage:

CM# script execute kerberos validation.sh -help

 
   
Help:
This script does basic validation of Kerberos operation, when device is using NTLM 
protocol for windows-domain login authentication.
It can be used as a pre-validation before migrating from NTLM to Kerberos authentication 
method.
 
   
It does following tests:
1. Active Directory reachability test
2. LDAP server and KDC server availability test
3. KDC service functionality test
   For this test to succeed device must have to join the domain before this test, if not 
have joined already.
4. Test for time offset between AD and Device (should be < 300s)
 
   
Script Usage:
kerberos_validation.sh [windows-domain name]
For example if Device has joined cisco.com then you need to enter: kerberos_validation.sh 
cisco.com
 
   

Step 2 Run the Kerberos validation script to verify that your network supports the Kerberos protocol before migrating from NTLM to Kerberos:

CM# script execute kerberos validation.sh windows_domain_name
 
   
WARNING: For windows authentication operation in 5.1.1, Device will use service on 
following ports.
         Please make sure they are not blocked for outbound traffic.
==========================================================================================
53 UDP/TCP, 88 UDP/TCP, 123 UDP, 135 TCP, 137 UDP, 139 TCP, 389 UDP/TCP, 445 TCP, 
464 UDP/TCP, 3268 TCP
 
   
Performing following tests on this device.
Test 1: Active Directory reachability test
Test 2: LDAP server and KDC server availability test
Test 3: KDC service functionality test
        For this test to succeed device must have to join the domain before this test, if 
not have joined already.
Test 4: Test for time offset between AD and Device (should be < 300s)
 
   
Tests are in progress. It may take some time, please wait...
 
   
Test 1: Active Directory reachability test : PASSED
Test 2: LDAP server and KDC server availability test : PASSED
Test 3: KDC service functionality test : PASSED
Test 4: Test for time offset between AD and Device (should be < 300s) : PASSED
 
   
Validation completed successfully!
 
   

Step 3 Change the device Windows domain login authentication from NTLM to Kerberos and upgrade your device, as described in the first procedure in this section.


Upgrading from a Prerelease Version to Version 5.3.1x

To upgrade from Cisco WAAS prerelease software to Version 5.3.1x, you must perform the following tasks to ensure a successful upgrade:

Restore the factory default settings by using the restore factory-default command.

Perform a fresh install from the rescue CD or USB flash drive.

When you upgrade to Version 5.3.1x, observe the following guidelines and requirements:

Upgrading to Version 5.3.1 is supported only from Versions 4.3.x, 4.4.x, 4.5.x, 5.0.x, 5.1.x, and 5.2.x. If you want to upgrade a Cisco WAAS device running an earlier version, first upgrade to one of these supported versions and then upgrade to the current 5.3.1 version.

Upgrading to Version 5.1.1 or later is not supported on the following platforms: WAE-511, WAE-512, WAE-611, WAE-612, WAE-7326, NME-WAE-302, NME-WAE-502, and NME-WAE-522. Cisco WAAS Version 5.1 or later does not operate on these appliances. Upgrading a device group is not allowed if the group contains any of the unsupported devices. If you have a Central Manager running on one of these unsupported platforms, you can migrate it to a supported platform by following the procedure in the "Migrating a Central Manager from an Unsupported Platform" section.

To take advantage of new features and bug fixes, we recommend that you upgrade your entire deployment to the latest version.

If you operate a network with devices that have different software versions, the Central Manager must be the highest version and no Cisco WAAS device should be running a version earlier than Version 4.2.1.

Upgrade the Central Manager devices first, and then upgrade the WAE devices. If you have a standby Central Manager, upgrade it first, before upgrading the primary Central Manager. After upgrading, restart any active browser connections to the Central Manager.

After upgrading a Central Manager, you must clear your browser cache, close the browser, and restart the browser before reconnecting to the Central Manager.

Before upgrading a Cisco WAAS Central Manager, make a database backup by using the cms database backup EXEC command. Use the copy disk ftp EXEC command to move the backup file to an external system. In case of any problem during the upgrade, you can restore the database backup that you made before upgrading by using the cms database restore backup-file EXEC command, where backup-file is the one created by the backup command.

After upgrading application accelerator WAEs, verify that the proper licenses are installed by using the show license EXEC command. The Transport license is enabled by default. If any of the application accelerators were enabled on the device before the upgrade, you should enable the Enterprise license. Configure any additional licenses (Video and Virtual-Blade) as needed by using the license add EXEC command. For more information on licenses, see the "Managing Software Licenses" section in the Cisco Wide Area Application Services Configuration Guide.

After upgrading application accelerator WAEs, verify that the proper application accelerators, policies, and class maps are configured. For more information on configuring accelerators, policies, and class maps, see the "Configuring Application Acceleration" chapter in the Cisco Wide Area Application Services Configuration Guide.

If you have two Central Managers that have secure store enabled and you have switched primary and standby roles between the two Central Managers, before upgrading the Central Managers to Version 5.3.1, you must reenter all passwords in the primary Central Manager GUI. The passwords that need to be reentered include user passwords and CIFS file server passwords. If you do not reenter the passwords, after upgrading to Version 5.3.1, the Central Manager fails to send configuration updates to WAEs and the standby Central Manager until after the passwords are reentered.

If you use the setup utility for basic configuration after upgrading to 5.3.1, WCCP router list 7 is used. Because the setup utility is designed for use on new installations, any existing configuration for WCCP router list 7 is replaced with the new configuration.

In Cisco WAAS Versions before 4.4.5, you were able to configure more memory for virtual blades on a 294-4G platform than was supported for virtual blades. To maintain stability, after upgrading from a Version earlier than 4.4.5, all memory allocated to virtual blades on the 294-4G platform is limited to 1 GB. This change affects any existing 294-4G virtual blade configurations.

Cisco WAAS Version 5.x no longer supports device group configuration of the following features: static bypass lists, vPath interception, and WCCP. When you are upgrading to Version 5.x from a previous version, any device group configurations of these features are copied to the individual devices and the device group settings are removed. WCCP settings can be copied between devices.

When upgrading from a Cisco WAAS Version earlier than 5.0, you must rename classifier names that contain a period (.) to remove the period. Classifiers with a period in their name are deleted on an upgrade. Replace periods in classifiers with a hyphen (-) or underscore (_) to prevent deletion.

When upgrading from a Cisco WAAS Version earlier than 5.0, pending reports are carried forward. Charts in reports are retained if they are still available; if they are no longer available, they are migrated to new charts. Any duplicated charts (as a result of migration) in a report are removed and all ICA application accelerator reports are removed because they are all new in Version 5.0. Custom reports are migrated to new custom reports in a similar way. Completed reports from before the upgrade are shown in the Completed Reports list and maintain their original format.

When upgrading from a Cisco WAAS Version earlier than 5.0, classifiers and policies are migrated to new Version 5.x class maps and policy rules. The same functionality is maintained, though the class map and policy framework are different.

When upgrading a Central Manager from a Cisco WAAS Version earlier than 5.0, the Cisco Wide Area File Services (WAFS) application definition is migrated to a new CIFS application, except if a CIFS application already exists, the application name change is not done. If you upgrade a WAE device that is not registered to a Central Manager, the WAFS application is not renamed. Any Cisco WAAS device that is still using the WAFS application in a policy rule after an upgrade to Version 5.x raises the following alarm: "WAFS application is configured for optimization. Consider changing the application name to CIFS." To clear the alarm, you can manually change the policy rule to use the CIFS application or restore default policies.

The ICA application accelerator in Cisco WAAS Version 5.1.1 and later is incompatible with previous releases. During optimization, if the WAE on one side is running a version earlier than 5.1.1 and the WAE on the other side is running Version 5.1.1 or later, all flows being handled by the ICA application accelerator are optimized with transport flow optimization (TFO) only. Both peer WAEs that are participating in the optimization process must be running Cisco WAAS Version 5.1.1 or later to benefit from ICA acceleration features.

When upgrading to Cisco WAAS Version 5.1 or later, any previous ICA class maps (Citrix-ICA and Citrix-CGP) are combined into a single class map named citrix that is monitored. In addition to matching traffic on ports 1494 and 2598, it includes a new condition that matches a dynamic port associated with the citrix protocol to support MSI streams. The enhanced ICA features (WAN secure, MSI support, and DSCP for QoS) are disabled by default.

The ICA charts in Cisco WAAS Version 5.0 and later are also different from those used in Version 4.5. If you are viewing the data from a Version 4.5 Cisco WAAS device, the charts appear empty due to the different data that the device is collecting. The ICA data for Version 4.5 Cisco WAAS devices are available in the system level TCP Summary Report by selecting the Remote-Desktop application.

Cisco WAAS Version 5.1 and later do not support NTLM Windows domain authentication or use of a nonstandard port (other than port 88) for Kerberos authentication. Upgrading from a Cisco WAAS Version earlier than 5.1 is blocked if either of these configurations are detected. You must change these configurations and ensure that your domain controller is configured for Kerberos authentication before proceeding with the upgrade. A script is provided to verify that your network supports Kerberos protocol before migrating from NTLM. For more information, see the "NTLM Interoperability" section. If no application is using the unsupported configurations on the device, then remove the unsupported configurations to upgrade.

Cisco WAAS Version 5.2 and later restrict the characters used in usernames to letters, numbers, period, hyphen, underscore, and @ sign, and a username must start with a letter or number. Any username not meeting these guidelines is prevented from logging in. Prior to upgrading the Central Manager to Version 5.2 or later, we recommend that you change any such usernames to valid usernames to allow login. For local users, you can do this through the Central Manager Admin > AAA > Users page. For remotely authenticated users, you must change the usernames on the remote authentication server.


Note Prior to upgrading the Central Manager to Version 5.2 or later, we strongly encourage you to change any usernames that use restricted characters; however if you must maintain existing usernames unchanged, please contact Cisco TAC.


When you upgrade from Cisco WAAS Version 4.x, you must reconfigure the custom EPM policy for a device or device group. You must first restore the default policy setting by selecting the Restore default Optimization Policies link for the device group in the Modifying Device Group window and then reconfigure your custom policy rules for the device.

Cisco WAAS Version 5.3 and later restricts the use of characters in the name and description field to alphanumeric characters, periods (.), hyphens (-), underscores (), and blank spaces when you create custom reports. When you upgrade from Cisco WAAS Version 4.x and you have custom reports that have special characters in the name or description field, Cisco WAAS automatically removes the special characters from the report name and description, and logs the modification in the central manager system (CMS) logs.

Migrating a Central Manager from an Unsupported Platform

If you have a Cisco WAAS Central Manager that is running on a hardware platform that is unsupported in Version 5.1 and later (such as a WAE-511/512/611/612/7326 or NME-WAE module), you are not allowed to upgrade the device to Version 5.1 or later. You must migrate the Central Manager to a supported platform by following the procedure in this section, which preserves all of the Central Manager configuration and database information.

Follow these steps to migrate a primary Central Manager to a new Cisco WAAS device:


Step 1 From the primary Central Manager CLI, create a database backup by using the cms database backup EXEC command. Move the backup file to a separate device by using the copy disk ftp command.

CM# cms database backup
Creating database backup file backup/cms-db-06-28-2012-15-08_5.0.1.0.15.dump
Backup file backup/cms-db-06-28-2012-15-08_5.0.1.0.15 is ready.
Please use `copy' commands to move the backup file to a remote host.
CM# cd /local1/backup
CM# copy disk ftp 10.11.5.5 / cm-backup.dump cms-db-06-28-2012-15-08_5.0.1.0.15.dump
 
   

Step 2 Display and write down the IP address and netmask of the Central Manager.

CM# show running-config interface
primary-interface GigabitEthernet 1/0
!
interface GigabitEthernet 1/0
 ip address 10.10.10.25 255.255.255.0
 exit
interface GigabitEthernet 2/0
 shutdown
 exit
!
 
   

Step 3 Shut down all the interfaces on the primary Central Manager.

CM# configure
CM(config)# interface GigabitEthernet 1/0 shutdown
 
   

Step 4 Replace the existing Central Manager device with a new hardware platform that can support Cisco WAAS Version 5.1. Ensure that the new Central Manager device is running the same software version as the old Central Manager.

Step 5 Configure the new Central Manager with the same IP address and netmask as the old Central Manager. You can do this in the setup utility or by using the interface global configuration command.

newCM# configure
newCM(config)# interface GigabitEthernet 1/0 ip address 10.10.10.25 255.255.255.0
 
   

Step 6 Copy the backup file created in Step 1 from the FTP server to the new Central Manager.

newCM# copy ftp disk 10.11.5.5 / cm-backup.dump cms-db-06-28-2012-15-08_5.0.1.0.15.dump
 
   

Step 7 Restore the database backup on the new Central Manager by using the cms database restore command. Use option 1 to restore all CLI configurations.

newCM# cms database restore backup/cms-db-06-28-2012-15-08_5.0.1.0.15.dump
Backup database version is from an earlier version than the current software version. 
Restored data will be automatically upgraded when cms services are enabled.
Restoring the backed up data. Secure-Store will be re-initialized.

3. Do not restore any CLI configurations from the backup.
Please enter your choice : [2] 1
Please enable the cms process using the command 'cms enable' to complete the cms database 
restore procedure.
Database files and node identity information successfully restored from file 
`cms-db-06-28-2012-15-08_5.0.1.0.15.dump'

Step 8 Enable the CMS service.

newCM# configure
newCM(config)# cms enable
 
   

Step 9 Verify that the Central Manager GUI is accessible and all Cisco WAAS devices are shown in an online state in the Devices window.

Step 10 (Optional) If you have a standby Central Manager that is running on unsupported hardware and is registered to the primary Central Manager, deregister the standby Central Manager.

standbyCM# cms deregister
 
   

Step 11 Upgrade the primary Central Manager to Cisco WAAS Version 5.1.x or later. You can use the Central Manager Software Update window or the copy ftp install command.

Step 12 Verify that the Central Manager GUI is accessible and all Cisco WAAS devices are shown in an online state in the Devices window.

Step 13 (Optional) Register a new standby Central Manager that is running Cisco WAAS Version 5.1.x or later.

newstandbyCM# configure
newstandbyCM(config)# device mode central-manager
newstandbyCM(config)# exit
newstandbyCM# reload
.
.
.
 
   

Wait for the device to reload, change the Central Manager role to standby, and register the standby Central Manager to the primary Central Manager.

newstandbyCM# configure
newstandbyCM(config)# central-manager role standby
newstandbyCM(config)# central-manager address 10.10.10.25
newstandbyCM(config)# cms enable
 
   

Ensuring a Successful RAID Pair Rebuild

RAID pairs rebuild on the next reboot after you use the restore factory-default command, replace or add a hard disk drive, delete disk partitions, or reinstall Cisco WAAS from the booted recovery CD-ROM.


Caution You must ensure that all RAID pairs are done rebuilding before you reboot your WAE device. If you reboot while the device is rebuilding, you risk corrupting the file system.

To view the status of the drives and check if the RAID pairs are in "NORMAL OPERATION" or in "REBUILDING" status, use the show disk details command in EXEC mode. When you see that RAID is rebuilding, you must let it complete that rebuild process. This rebuild process may take several hours.

If you do not wait for the RAID pairs to complete the rebuild process before you reboot the device, you may see the following symptoms that could indicate a problem:

The device is offline in the Central Manager GUI.

CMS cannot be loaded.

Error messages say that the file system is read-only.

The syslog contains errors such as "Aborting journal on device md2," "Journal commit I/O error," "Journal has aborted," or "ext3_readdir: bad entry in directory."

Other unusual behaviors occur that are related to disk operations or the inability to perform them.

If you encounter any of these symptoms, reboot the WAE device and wait until the RAID rebuild finishes normally.

Downgrading from Version 5.3.1x to a Previous Version

Note the following guidelines and considerations for downgrading:

Downgrade is supported only to Versions 4.3.x, 4.4.x, 4.5.x, 5.0.x, 5.1.x, and 5.2.x. Downgrade is not supported to Versions 4.2.x through 4.0.x.

After downgrading a Cisco WAAS Central Manager, you must clear your browser cache, close the browser, and restart the browser before reconnecting to the Central Manager.

On the Cisco 4451-X Integrated Services Router running ISR-WAAS, downgrading to a version earlier than 5.2.1 is not supported.

On the UCS E-Series Server Module installed in a Cisco ISR G2 Router and running vWAAS, downgrading to a version earlier than 5.1.1 is not supported. On the UCS E-Series Server Module installed in the Cisco 4451-X Integrated Services Router and running vWAAS, downgrading to a version earlier than 5.2.1 is not supported. On other vWAAS devices you cannot downgrade to a version earlier than 4.3.1.

If the Central Manager is downgraded to a version earlier than 5.2.1, it can no longer manage AppNav-XE clusters and devices and all related configuration records are removed.

On WAVE-294/594//8541 models with solid state drives (SSDs) you cannot downgrade to a version earlier than 5.2.1.

On WAVE-294/594/694/7541/7571/8541 models you cannot downgrade to a version earlier than 4.4.1.

When downgrading Cisco WAAS devices, first downgrade application accelerator WAEs, then the standby Central Manager (if you have one), and lastly the primary Central Manager.

If you have a standby Central Manager, it must be registered to the primary Central Manager before the downgrade.

When downgrading an AppNav Controller device to a version earlier than 5.0.1, you must deregister the device from the Central Manager, change the device mode to application-accelerator, downgrade the device, and then reregister the device after the downgrade (or you can reregister the device before downgrading). If you do not deregister the device before downgrading, the device goes offline and the device mode is not set correctly. In that case, use the cms deregister force EXEC command to deregister the device and then reregister it by using the cms enable global configuration command.

If the AppNav Controller device contains an AppNav Controller Interface Module, the module is not recognized by Cisco WAAS versions earlier than 5.0.1 and is nonfunctional after a downgrade.

Locked-out user accounts are reset upon a downgrade.

Any reports and charts that are not supported in the downgrade version are removed from managed and scheduled reports when you downgrade to an earlier version. Any pending reports that were carried forward from an upgrade from a version earlier than 5.0 are maintained.

When downgrading to a version earlier than 4.4.1, the DRE cache is cleared and the DRE caching mode for all application policies is changed to bidirectional (the only available mode prior to 4.4.1). Before downgrading a WAE, we recommend that you use the Central Manager GUI to change all policies that are using the new Unidirectional or Adaptive caching modes to the Bidirectional caching mode.

When downgrading a Central Manager to a version earlier than 4.4.1, if the secure store is in auto-passphrase mode, downgrade is not allowed. You must switch to user-passphrase mode before you can downgrade to a software version that does not support auto-passphrase mode.

Prior to downgrading to a version earlier than 4.4.1, we recommend that you change the WCCP service IDs back to their default values of 61 and 62, and change the failure detection timeout back to the default value of 30 seconds, if you have changed these values. Only these default values are supported in versions prior to 4.4.1 and any other values are lost after the downgrade. If a WAE is registered to a Central Manager, it is configured with the default service IDs of 61 and 62 after it is downgraded and comes back online.

Current BMC settings are erased and restored to factory-default when you downgrade Cisco WAAS to a version earlier than 4.4.5.

To downgrade the Cisco WAAS Central Manager (not required for WAE devices), follow these steps:


Step 1 (Optional) From the Central Manager CLI, create a database backup by using the cms database backup EXEC command. Move the backup file to a separate device by using the copy disk ftp command.

CM# cms database backup
Creating database backup file backup/cms-db-06-28-2012-15-08_5.0.1.0.15.dump
Backup file backup/cms-db-06-28-2012-15-08_5.0.1.0.15 is ready.
Please use `copy' commands to move the backup file to a remote host.
CM# cd /local1/backup
CM# copy disk ftp 10.11.5.5 / 06-28-backup.dump cms-db-06-28-2012-15-08_5.0.1.0.15.dump
 
   

Step 2 Install the downgrade Cisco WAAS software image by using the copy ftp install EXEC command.

CM# copy ftp install 10.11.5.5 waas/4.4 waas-universal-4.4.5c.4-k9.bin
 
   

Step 3 Reload the device.


Downgrading the database may trigger full updates for registered devices. In the Central Manager GUI, ensure that all previously operational devices come online.

Cisco WAE and WAVE Appliance Boot Process

To monitor the boot process on Cisco WAE and WAVE appliances, connect to the serial console port on the appliance as directed in the Hardware Installation Guide for the respective Cisco WAE and WAVE appliance.

Cisco WAE and WAVE appliances may have video connectors that should not be used in a normal operation. The video output is for troubleshooting purposes only during BIOS boot and stops displaying output as soon as the serial port becomes active.

Operating Considerations

This section includes operating considerations that apply to Cisco WAAS Software Version 5.3.1x and contains the following topics:

Central Manager Report Scheduling

Cisco WAAS Express Policy Changes

Virtual Blade Configuration From File

Using Autoregistration with Port-Channel and Standby Interfaces

Disabling WCCP from the Central Manager

Changing Device Mode To or From Central Manager Mode

TACACS+ Authentication and Default User Roles

Internet Explorer Certificate Request

Default Settings with Mixed Versions

Central Manager Report Scheduling

In the Cisco WAAS Central Manager, we recommend running system wide reports in device groups of 250 devices or less, or scheduling these reports at different time intervals, so multiple system wide reports are not running simultaneously.

Cisco WAAS Express Policy Changes

Making policy changes to large numbers of Cisco WAAS Express devices from the Central Manager may take longer than making policy changes to Cisco WAAS devices.

Virtual Blade Configuration From File

If you copy the device configuration to the running-config from a file (for example, with the copy startup-config running-config command), configuration changes from the file are applied to the device without confirmation. If a virtual blade disk configuration exists in the configuration file and it is different from the actual device configuration, the device virtual blade disk configuration is removed and replaced with the disk configuration from the file. You lose all data on the virtual blade disks.

Using Autoregistration with Port-Channel and Standby Interfaces

Autoregistration is designed to operate on the first network interface and will not work if this interface is part of a port-channel or standby. Do not enable the auto-register global configuration command when the interface is configured as part of a port-channel or standby group.

Disabling WCCP from the Central Manager

If you use the Central Manager to disable WCCP on a Cisco WAAS device, the Central Manager immediately shuts down WCCP and closes any existing connections, ignoring the setting configured by the wccp shutdown max-wait global configuration command (however, it warns you). If you want to gracefully shut down WCCP connections, use the no enable WCCP configuration command on the Cisco WAAS device.

Changing Device Mode To or From Central Manager Mode

If you change the device mode to or from Central Manager mode, the DRE cache is erased.

TACACS+ Authentication and Default User Roles

If you are using TACACS+ authentication, we recommend that you do not assign any roles to the default user ID, which has no roles assigned by default. If you assign any roles to the default user, external users that are authenticated by TACACS+ and who do not have the waas_rbac_groups attribute defined in TACACS+ (meaning they are not assigned to any group) can gain access to all the roles that are assigned to the default user.

Internet Explorer Certificate Request

If you use Internet Explorer to access the Central Manager GUI Version 4.3.1 or later and Internet Explorer has personal certificates installed, the browser prompts you to choose a certificate from the list of those installed in the personal certificate store. The certificate request occurs to support Cisco WAAS Express registration and is ignored by Internet Explorer if no personal certificates are installed. Click OK or Cancel in the certificate dialog to continue to the Central Manager login page. To avoid this prompt, remove the installed personal certificates or use a different browser.

Default Settings with Mixed Versions

If a Central Manager is managing Cisco WAAS devices that have different versions, it is possible that a feature could have different default settings in those different versions. If you use the Central Manager to apply the default setting for a feature to mixed devices in a device group, the default for the Central Manager version is applied to all devices in the group.

Added the keywords and arguments cpu percent enable and softirq enable to configure the CPU threshold level, enabling the CPU load monitoring, and enabling softirq CPU load monitoring.


Using Previous Client Code

If you have upgraded to Cisco WAAS Version 5.3.1 and are using the WSDL2Java tool to generate client stubs that enforce strict binding, earlier version client code (prior to 4.3.1) may return unexpected exceptions due to new elements added in the response structures in 4.3.1 and later releases. The observed symptom is an exception related to an unexpected subelement because of the new element (for example, a deviceName element) in the XML response.

To work around this problem, we recommend that you patch the WSDL2Java tool library to silently consume exceptions if new elements are found in XML responses and then regenerate the client stubs. This approach avoids future problems if the API is enhanced with new elements over time.

You must modify the ADBBeanTemplate.xsl file in the axis2-adb-codegen-version.jar file.

To apply the patch, follow these steps:


Step 1 List the files in the axis2-adb-codegen-version.jar file:

# jar tf axis2-adb-codegen-1.3.jar

META-INF/maven/org.apache.axis2/axis2-adb-codegen/pom.xml
META-INF/maven/org.apache.axis2/axis2-adb-codegen/pom.properties
 
   

Step 2 Change the ADBBeanTemplate.xsl file by commenting out the following exceptions so that the generated code consumes the exceptions:

<xsl:if test="$ordered and $min!=0">
  else{
    // A start element we are not expecting indicates an invalid parameter was passed
    // throw new org.apache.axis2.databinding.ADBException("Unexpected subelement " + 
reader.getLocalName());
  }
</xsl:if>
 
   
.
.
.
 
   
  while (!reader.isStartElement() &amp;&amp; !reader.isEndElement())
    reader.next();
  //if (reader.isStartElement())
    // A start element we are not expecting indicates a trailing invalid property
    // throw new org.apache.axis2.databinding.ADBException("Unexpected subelement " + 
reader.getLocalName());
</xsl:if>
 
   
.
.
.
 
   
<xsl:if test="not(property/enumFacet)">
  else{
    // A start element we are not expecting indicates an invalid parameter was passed
    // throw new org.apache.axis2.databinding.ADBException("Unexpected subelement " + 
reader.getLocalName());
  }
 
   

Step 3 Re-create the jar file and place it in the CLASSPATH. Delete the old jar file from the CLASSPATH.

Step 4 Use the WDL2Java tool to execute the client code using the modified jar.
