•Troubleshooting
Using Reports
The following changes and additions have been made to the Using Reports topics in the online help and user guide:
•Using URL-Based Exporting Report Data
•Displaying Trend Reports
Using URL-Based Exporting Report Data
The following information is missing from the online help and user guide. This feature allows you to manually enter a URL in the WLSE to export report data, rather than using the GUI export function.
Procedure
Step 1 Log in to the WLSE.
Step 2 In the browser, enter the following URL:
http://{WLSE name:port | ipaddress:port}/servlet/com.cisco.nm.wlse.util.WLSEReportsExportServlet?{parameters}
The parameters are as follows and are case sensitive:
reporttype={Wireless Client | group | device}
id={group name | client macaddress | device name | device ip address}
family= {Router | Switch | AccessPoint | Wireless Client | EAP | RADIUS | EAP-MD5 | group}
reportName ={name} Enter the name of the report.
filetype= {csv | xml | pdf}
reportcategory={current | trends}
tzOffset={time}The time zone offset in minutes for GMT/UTC. Add a + (plus) or - (minus) as appropriate. For example, -300 minutes means 5 hours.
For trend reports, you must add the following parameters:
startdate={YYYY-MM-DD-hh-mm-ss}
enddate={YYYY-MM-DD-hh-mm-ss}
Note The start date and end date are interpreted relative to the time zone offset provided.
topNVal This is required only to display Top N Reports.
An example of a URL to generate CSV output for Group Performance Report: RF Utilization, for a group of 350 access points, with start date and time of December 21 00:00:00 GMT+05:30 2002, and an end date and time of December 21 23:59:59 GMT+05:30 2002 is as follows:
http://172.10.29.117:1741/servlet/com.cisco.nm.wlse.util.WLSEReportsEx

Displaying Trend Reports
The following sections in the Displaying Trends section of the online help and user guide are missing information:
•Required Aggregation Cycles for Displaying Reports
•Displaying a Group Report
•Displaying the Server Response Time Graph
Required Aggregation Cycles for Displaying Reports
A minimum number of aggregation cycles are required for the following trend reports to display data:
Report
|
Minimum Aggregation Cycle Required
|
Group Performance Report: RF Utilization
|
One cycle1
|
Group Performance Report: Ethernet Utilization
|
Top N Number of Associations
|
Top N Percentage Errors
|
AP and Bridge Performance: Tabular
|
Two cycles
|
AP and Bridge Performance: Graph
|
AP and Bridge Ethernet Transmission Statistics
|
AP and Bridge RF Transmission Statistics
|
Displaying a Group Report
The group report for a group containing 100 or more access points might take several minutes to appear due to the amount of trend data that must be retrieved.
Displaying the Server Response Time Graph
The Server Response Time graph has been modified in the following ways:
•It is no longer a graph; it is a bar chart.
•It displays a -1 value when the server cannot be reached.
•It displays a 0 value when the value is less than 0.5.
•The time is displayed in seconds; not milliseconds.
Configuring Devices
The following changes and additions have been made to the Configuring Devices topics in the online help and user guide:
•Using Express Template
•Importing a Template
•Automating Configurations
Using Express Template
The following information has changed in the Using Express Template section:
•The field Ensure Compatibility with Cisco has been changed to Ensure Compatibility with non-Aironet.
•The field Ensure Compatibility with 1MB/sec Clients has been added.
Importing a Template
The following information is missing from the Importing a Template section: When importing a template from a file, if no template name is entered in the Template Name field, the existing file name will appear as the default template name.
Automating Configurations
The following information is missing from the Assigning an Auto-Managed Configuration section: Auto-managed templates that are uploaded to access points using SNMP protocol will work only for software versions 11.08T or later. Earlier versions do not support configuration updates using SNMP protocol.
Updating Device Firmware
The Updating Device Firmware section incorrectly states that you can enter a hostname in the field under Proxy Information called Proxy IP. You can only enter the IP address of the proxy server.
Troubleshooting
The Troubleshooting section is missing the following information for Configuration:
Symptom
|
Probable Cause
|
Possible Solution
|
A configuration undo job for adding a user shows as successful but the user is not removed from the access point.
|
Because there is no way to get user table information from the access point, the WLSE can undo only newly added users. If an existing user is modified, the undo function will not be able to restore the previous settings for the user.
|
Not applicable.
|
Known and Resolved Problems
This section contains the following tables:
•Table 1 describes the problems known to exist in this release.
•Table 2 describes the browser-related problems known to exist in this release.
•Table 3 describes problems resolved since the last release of WLSE.

Summary
|
Explanation
|
CSCdx51276
|
Two roles with the same name can be created, but only one role will be allowed tab and subtab access.
|
Two user roles with the same name, each given different tab and subtab access privileges, can be created. However, only one of the roles will be assigned all the access privileges; the other role will be empty.
To work around this problem, give each user role a unique name.
|
CSCdy67138
|
Large configuration files cause SNMP jobs to fail on versions prior to 12.00T.
|
Access points fail to upload configuration files greater than 4Kbytes.
To work around this problem create several small configuration templates to upload.
|
CSCdz19851
|
The values for the 11a radio data rates in a template imported from an AP1200 are blank.
|
When you import a configuration from a 1200 AP, the 11a radio's data rates are not imported correctly, and are displayed as blank.
There is no workaround for this problem.
|
CSCdz23682
|
Some characters used in text entry fields for creating a template cause errors.
|
When creating a template, use of the following characters in any of the text entry fields could cause errors:
•+ (plus)
•# (pound)
•& (ampersand)
•\ (slash)
To work around this problem, do not use these characters in any text entry fields.
|
CSCdz24905
|
Substituting devices on the network creates duplicate entries for the devices.
|
When you:
1. Perform an initial discovery of an access point and manage it with the WLSE.
2. Replace that device with another access point using the same IP address.
3. Run discovery again.
The new access point shows up as part of the new devices group and the old access point remains listed in the managed group.
To work around this problem:
1. Delete the device from the managed list before replacing it.
2. Clear arp cache on the connected switches/routers for network connectivity.
|
CSCdz34064
|
Data in the Current Client Association Reports is inaccurate.
|
When a client associates with an access point, it is reflected in the Current Client Association Report. However, when the client subsequently disassociates from the access point, the client will still show up as associated in the report.
To work around this problem, you must view the information for the access point in the Group Report, which displays accurate data. Note the value listed in the Number of Clients connected column and the timestamp in the As Of column.
You can then view the Current Client Association Report, and based on the timestamp you got from the Group Reports be able to discern which clients are currently associated.
|
CSCdz37464
|
You cannot add a new policy group to an access point with version 12.00T.
|
This is a bug in the 12.00T software; not the WLSE. When you try to add a new policy group to an access point with version 12.00T it returns errors.
There is no workaround for this problem.
|
CSCdz41224
|
Unmanaging or deleting a device while running a firmware job will leave the job pending for that device.
|
If you create and run a firmware job for a group of devices, then delete or unmanage a device within the group when the job is only partially complete, the job will be listed as completed with a start and end time. However, the device that was unmanaged or deleted will show a status of "not verified" with a blank end time, and the job remains pending.
There is no workaround for this problem.

CSCdz42008
|
When upgrading from Release 1.1 to 1.3, the login screen does not accept a valid username and password. It refreshes without any error message.
|
When upgrading from Release 1.1 to Release 1.3 using a 1.3 recovery CD on a Windows PC with Microsoft Internet Explorer 6.0, the login screen does not accept a valid username and password.
To work around this problem:
1. Select Tools > Internet Options > Privacy.
2. Change privacy setting to Low.

|
Configuration job fails using Netscape Navigator
|
The first job created using Netscape Navigator is successful, but subsequent jobs may not be.
To work around this problem, disable cache on your browser as follows:
1. Select Edit > Preferences > Advanced > Cache.
2. Select Every Time in the Document in cache compared to document on network.
|
CSCdy85555
|
Resizing the Import or Export window on Netscape 4.79 causes the screen to revert to the main Templates window.
|
When the Configure > Templates > Import and Configure > Templates > Export windows are resized in Netscape 4.79, it causes the browser to revert to the main Templates window and will not relaunch the Import or Export window when the Import and Export buttons are clicked.
To work around this problem, close the browser and log in again.
|
None
|
Window resizing in Netscape Navigator causes page reloads.
|
When a window whose content is not cached is resized, Netscape Navigator sends a page request to the server.
This can cause any of the following problems:
•Work that is in progress could be interrupted, and the default page of the last module accessed from the navigation bar could be displayed.
•Any data that was being entered in a dialog box could be lost.
•Some of the pages may not show correct information, particularly those containing the date and time.
|
CSCdz17889
|
Trend data displayed under Reports > Device Center using Netscape 4.79 does not show up.
|
Trend reports display correctly from Reports > Trends.
To work around this problem do one of the following:
•Use Microsoft Internet Explorer to view trend data from Reports > Device Center.
•If using Netscape 4.79 to view trend reports, use Reports > Trends.

|
No warning is given when you configure an incorrect location for a backup, or when the server you have designated for the backup location is down or unavailable.
|
When you perform a backup, no warning is issued and no data is saved if you have configured the backup location incorrectly.
However, if you have configured the location correctly, you can use the Test button to verify that the location is accessible.
