Documentation Updates

The latest version of the online help and/or User Guide for the CiscoWorks Wireless LAN Solution Engine does not include additions and corrections to the following sections:

Disabling or Enabling Telnet and Selecting SSH Type

This topic incorrectly states that Telnet is enabled by default. It is disabled by default.

Adding an AAA Server

The procedure for configuring a RADIUS AAA server states that only ACS servers can be configured as RADIUS AAA servers. However, CAR RADIUS servers can also be configured as RADIUS AAA serves.

Displaying Data Rate

This topic incorrectly states that the highest basic rate set of the APs is displayed on the Location Manager floor map. The topic should read that the highest operational rate set, whether it is a basic rate or the enabled rate, of the APs is displayed on the floor map.

Managing Processes

This topic incorrectly omits the WirelessSvcMgr process. The WirelessSvcMgr is the Radio Manager virtual machine.

Radio Management

The Radio Management chapter should clearly state that if you are using WDS on your wireless LAN, you must:

1. Configure the access point that is providing WDS.

2. Configure the WLSE to authenticate with the access point providing WDS.

Refer to the online help for the CiscoWorks Wireless LAN Solution for specific instructions.

In addition, the online help should state the following requirements:

The Radio Management portion of WLSE requires the following combinations of products and versions:

WLSE (Release 2.5)

IOS AP Release (12.2(13)JA

Cisco Aironet 11b-Client with 12.08 release

Radio Management functionality, such as client walkabout and radio monitoring, works when the client image is release 12.08 only. In addition, Radio Management functionality supports 802.11b radios only.

Naming Guidelines

The WLSE does not allow duplicate job names. Firmware, configuration, and radio management jobs must have unique names.

Known and Resolved Problems

Table 2 describes the problems known to exist in this release; Table 3 describes problems solved since the last release.


Note To obtain more information about known problems, access the Cisco Software bug Toolkit at http://www.cisco.com/cgi-bin/Support/Bugtool/home.pl. (You will be prompted to log into Cisco.com.)


Table 2 Known Problems in the WLSE 

Bug ID
Summary
Explanation

CSCea91955

Fault Notification Syslog messages from WLSE are displayed in a truncated form on the Resource Manager Essentials (RME) 3.4 Syslog Standard Report.

The RME 3.4 Syslog Standard Report displays fault notification syslog messages sent in XML message format or in plain text message format in a truncated form.

To work around this problem and view the syslog messages in an untruncated form, see the following flat syslog file located in:

On the Solaris 2.8 based RME 3.4 server: /var/log/syslog_info

On the Windows 2000 based RME 3.4 server: C:/Program Files/CSCOpx/log/syslog.log

CSCeb23307

Entering dates under the Advanced Options for Device Discovery can generate an error message even if the dates are valid.

When you select Devices > Discover > Discover > Advanced Options, and set the Filters Valid From date, only the day and month are checked for validity, not the year. Therefore, if you enter a date range such as 12/30/2003 to 01/20/2004, you will get an error message stating that the "Start Date is greater than End Date," even though the date range is valid.

To work around this problem, do not enter date interval values when using the MAC filtering option.

CSCeb23714

You will get an error if you use the pound (#) sign in the password for device Telnet credentials.

When you use a pound (#) sign in the password field under Devices > Discover > Device Credentials > Telnet/SSH/User Password, a 500 Internal Server Error displays.

To work around this problem, do not use pound (#) sign in the password.

CSCeb36372

The Client Historical Association report does not contain a disassociation time.

The Client Historical Association report does not have the information about last time a client associated with the access point, the time it disconnected from the access point, the duration of the association, or the association state.

There is no workaround for this problem.

Note In the current release, only association times of a client are supported. Disassociation time of the client is not available in this release.

CSCeb85931

In the Assisted Site Survey Wizard, the lock method should be implemented

You can have a maximum of five Assisted Site Survey Wizard sessions, each using separate APs and clients, running at one time. There is currently no lock mechanism that prevents you from running more than one session on the same APs and clients.

To work around this problem, do not run more than one session of the Assisted Site Survey Wizard on the same APs and clients.

CSCec03535

Switch port detection does not work under some conditions.

If you have a switch in a network that relies on trunking to pass packets and manage APs, but rogue AP ports are not trunk enabled, switch port detection fails.

To work around this problem, enable trunking on the rogue AP's switch port.

CSCec33330

A configuration job for a template which includes a banner command that spans multiple lines, will not complete successfully.

If the configuration template used in the configuration job has banner command spanning multiple lines in the Custom Values section, the job may either report a failure or continue to appear in a Running state.

To work around this problem either remove the banner command or make sure it only spans a single line, then run the configuration job again.

CSCec38013

When you upgrade to Release 2.5, the fault "Ethernet BVI1 port is down" on IOS access points is not deleted.

The IOS access point fault "Ethernet BVI1 port is down" in a Release 2.0 WLSE is not deleted after an upgrade to WLSE Release  2.5.

To work around this problem, after you upgrade to Release 2.5:

1. Disable fault polling for the access point Ethernet Port Status Threshold.

2. Manually clear the 'Ethernet BVI1 port is down' faults for the IOS access points.

CSCec40088

WDS server data defined in Release 2.0 Wireless Services templates is not retained after an upgrade to Release 2.5.

If you created a template in Release 2.0, by selecting Configure > Templates > IOS > Wireless Services > WDS, and added server data, the data will not retained when you upgrade to Release 2.5.

To work around this problem, you will have to add the server data after you have upgraded to Release 2.5.

CSCec41188

You cannot add a LEAP server to the WLSE if it is already a managed access point.

You cannot add an access point, which is running the local RADIUS service and is managed as an access point by the WLSE, as a LEAP server. The WLSE will view it as a duplicate device.

There is no workaround for this problem.

CSCec42478

Dual band, non-IOS 1200 access points do not generate a Leap Disabled fault for the 802.11a RF port.

When LEAP is disabled on the 802.11a RF port of a non-IOS, 1200 access point, it is not reported under Faults > Display Faults.

This is a problem with the access point software, not the WLSE. Please refer to Bug ID CSCec47797.

There is no workaround for this problem.

CSCec52282

You cannot use the CLI command ip domain-name to reset your domain.

The CLI command IP domain-name does not work correctly.

To work around this problem, use the CLI command erase config to erase the previous WLSE configuration, then run the setup program and enter your network information.

CSCec53133

No Client Walkabout data is collected when you select "Use AP Current Power Setting."

When you chose the AP Power Setting in Client Walkabout, the "Use AP Current Power Setting" option does not work.

To work around this problem, select one of the other options: Use AP Maximum Power Setting or Use No More than user-defined mW.

CSCec54430

There are no SSIDs listed under Faults > Manage Fault Profiles > Access Point Policies > EAP per SSID Enforced for non-IOS, dual band, 1200 access points.

Dual band, non-IOS 1200 access points running version 12.03T, fail to list the Available SSIDs for Radio 802.11a in the EAP per SSID Enforced policy under Faults > Manage Fault Profiles.

There is no workaround for this problem.

CSCec57354

AP350 radio interface might be disabled due to excessive scans after running for 11/2 days

After running scans for 1 1/2 days, the AP radio interface might be disabled in some network environments.

To work around this problem, do not schedule frequent AP radio scans in a 24-hour period. Instead, use Radio Monitoring, which is not service disrupting, to collect ongoing radio measurement data. Power cycle the AP if the radio interface is disabled.

CSCec57502

When you export trend report data in a CSV format, some of the attributes are incomplete.

When you use CSV format to export trend report data, the data in the CSV file is incomplete.

There is no workaround for this problem.

CSCec59512

Duplicate EAP Disabled per SSID faults are generated for the 11b radio of dual band 1200 access point.

Dual band, 1200 access points generate duplicate EAP Disabled per SSID faults under Faults > Display Faults.

There is no workaround for this problem.

CSCec64486

Firmware conversion jobs are reported as successful even though they are not.

Sometimes firmware conversions from non-IOS to IOS are terminated quickly and display as successful. However, the Job Run log indicates an error downloading the non-IOS configuration.

To work around this problem, increase the SNMP timeout and retries for those devices, then run the job again.

CSCec70880

Disabling Interference Detection causes hung Radio Management processes

If you disable the Interference Detection fault setting (Faults>Manage Network-Wide Settings>Interference Detection), this can result in hung Radio Management operations (for example, radio scan).

To work around this problem, never disable Interference Detection. If you are not interested in the interference faults, set the fault settings to the maximum values to reduce the number of interference faults generated.

CSCec70915

"SNMP unreachable" APs can cause Client Walkabout to never stop.

If any APs included in a client walkabout session are "SNMP unreachable," client walkabout does not stop. This prevents other jobs (for example, radio scan and other client walkabout tasks) from running. The user interface indicates that the task has stopped, but the task is still running in the background.

To work around this problem, make sure all APs you select for a client walkabout session are SNMP reachable before starting the client walkabout. If the client walkabout never stops, you need to restart WLSE.

CSCec72920

After converting an non-IOS access point to an IOS access point, the correct native VLAN may not be configured.

If you convert from a non-IOS access point to an IOS access point, and the non-IOS access point does not have a native VLAN configured, a VLAN will be automatically assigned as the native VLAN. However, the assigned native VLAN may not be correct.

To work around this problem, log in to the access point and change the native VLAN to the correct one.

CSCsa03154

When you log in, you get the following error message: User role empty.

After applying a patch, you may get an error message when you log in.

To work around this problem, reboot the machine.

CSCsa08621

When you use the CLI command interface to set the WLSE to half-duplex, the WLSE crashes.

Setting the WLSE interface duplex mode may cause a catastrophic segmentation fault that corrupts the WLSE flash.

There is no workaround for setting the duplex mode.

Recovery requires erasing WLSE configuration in flash and rerunning the setup script.

To recover, do the following:

1. Connect to the WLSE console port

2. Power cycle the WLSE

3. When the WLSE powers up, wait for the GRUB loader to present you with OS options

4. At the GRUB loader, select CiscoBreR. This will boot you into the recovery image and present you with a Linux shell prompt.

5. At the shell prompt, type the command erase config. This will erase the flash (leaving the WLSE database intact), then reboot the WLSE.

6. When the WLSE reboots, you will be forced to rerun the setup script.


Table 3 Resolved Problems in the WLSE 

Bug ID
Summary
Explanation

CSCdz34064

The number of clients seen in the AP Associations report and the Group Client Association report do not match.

The data in the Number of Clients Connected field in the Group Client Association report is collected using the performance inventory. The client information displayed in the AP Associations Report is collected using the client inventory.

Because the inventory polling frequencies for client and performance inventory are mismatched, the data in these reports do not always match.

There is no workaround for this problem.

However, in the case of some access points, you can use the Run Inventory Now and Scheduled Inventory features to synchronize the data.

CSCea61722

The 1200 access point Cisco IOS images do not show up when importing from Cisco.com.

When you try to import a Cisco IOS image for the AP 1200 from Cisco.com by selecting Firmware > Import > From Cisco.com, the image does not show up.

To work around this problem, download the firmware image from Cisco.com, then import it to the WLSE by selecting Firmware > Import > From Desktop.

CSCea88793

A non-IOS to Cisco IOS access point conversion job is successful but is reported as not verified.

When you run a non-IOS to IOS conversion job, the results are displayed as not verified even though the job is successful. The timeout and retries values need to be increased.

To work around this problem, and to ensure that future jobs are successful, do the following:

1. Access the Job Properties dialog box by entering the following URL: http://wlse IP address:1741/debug/jobprops.jsp.

2. Increase the value for

Vxworks to IOS SNMP timeout.

Vxworks to IOS SNMP retries.

Device reboot wait timeout.

CSCeb19507

An error message appears in the Install Software Updates window in two possible circumstances:

After having upgraded to Release 2.0 from a previous release of the WLSE.

On a newly installed WLSE, Release 2.0.

After having upgraded to a WLSE 2.0 or after newly installing a WLSE 2.0, if you either:

1. Use the CLI command hostname to change the hostname to one that is not configured under IP Name Server on the WLSE.

2. Use the CLI commands services stop then services start to stop then start services.

then the WLSE will not accept the host name change, and the following problems occur:

An error message appears in the Install Software Updates window.

You cannot e-mail any log files (e.g. tomcat.log) in the View Log File window.

The "AAA Server is Not Available" fault is erroneously generated and stays in active state indefinitely even though the AAA servers are actually available.

Fault notification e-mails display the previous hostname, not the current one.

To work around this problem, use the CLI command reload after having executed foregoing two steps.

CSCeb32794

Specific trap host configuration using IOS configuration templates removes previously configured trap host configurations.

Whenever a specific trap host is defined using the IOS configuration template, all previous specific trap host configuration commands are removed from the access point by the WLSE.

For example, if you use the WLSE to configure host xxx.xxx.xxx.xxx to be the trap receiver for receiving hot standby switchover type traps, then push it to the access point, the access point will have this host as the trap receiver for switchover type traps. If the access point already has another trap receiver, yyy.yyy.yyy.yyy, configured to receive association and disassociation type traps, it will be removed.

This is because the WLSE generates commands to disable all non switchover type traps (because this is the only type we selected in the template) from being generated.

To work around this problem, select trap types that are already configured on the access point, in addition to the new trap type.

Using the example above, if switchover and associate and disassociate type traps are selected, then the WLSE will not disable the associate and disassociate type traps.

You can also use commands in the custom templates to work around this problem.

CSCeb40356

When you rediscover an already-discovered device, inventory is not run automatically.

When discovery is run on an already-discovered device, even though it is auto-managed, the inventory feature is not triggered.

To work around this problem, you must run an on-demand inventory by selecting Administration > Discover > Inventory > Run Inventory Now, or wait for the next available inventory cycle.

CSCeb46145

The non-IOS to Cisco IOS upgrade images are not available from Cisco.com.

When you try to download an upgrade image from Cisco.com, the image does not show up.

To work around this problem, download the firmware image from Cisco.com to your desktop, then import it to the WLSE by selecting Firmware > Import > From Desktop.

CSCeb50004

The View current faults for this setting link under Faults > Manage Profiles cannot be used to clear Vlan WEP key length policy violation faults.

When you display WEP Encryption per VLAN security policy profile under Faults > Manage Profiles, then click View current faults for this setting, the window for the previously selected link in a different policy window appears. This means that the VLAN WEP key length policy violation fault cannot be cleared using this link.

To work around this problem:

1. Select Faults > Display Faults

2. Select the Vlan WEP key length policy violation faults for the affected access points

3. Click Clear.

When you select the WEP Key Length security policy window under Faults > Manage Profiles, then click View current faults for this setting, the window for the previously selected link in a different policy window appears. This means the WEP key length policy violation fault cannot be cleared using this link.

To work around this problem:

1. Select Faults > Display Faults

2. Select the Vlan WEP key length policy violation faults for the affected access points

3. Click Clear.

CSCeb52919

Initial configuration of RADIUS TACACS+, or MS NT Domain authentication fails.

When you configure the RADIUS, TACACS+, or MS NT Domain authentication modules for the first time, the WLSE does not accept the configuration; it retains the original Local Authentication module.

To work around this problem, configure the RADIUS, TACACS+, or MS NT Domain authentication modules a second time.
