CSCeb36372
|
The Client Historical Association report does not contain a disassociation time.
|
The Client Historical Association report does not have information about the last time a client associated with the AP, the time it disconnected from the AP, 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.

CSCec41188
|
You cannot add an AP-based LEAP server to the WLSE if it is already a managed by WLSE.
|
You cannot add an AP-based LEAP/EAP-FAST server to WLSE if that AP is already being managed by WLSE. The WLSE views it as a duplicate device.
There is no workaround for this problem.
|
CSCed94324
|
Detach/IP Address Change events during Roam event stress-2gclient.
|
If you select Reports > Wireless Clients > Client EAP UserName or MAC Address > Client Historical Association, sometimes an IP Address Change event is reported immediately after a Roam event, even though no IP address change has occurred for the specified client. In addition, sometimes a Detach From WDS event is reported immediately after a Roam event, even though the specified client has not left the WDS indicated in the previous Roam event.
This problem occurs for certain clients that are authenticated using LEAP and are not using the CCKM fast-roaming feature.
To work around this problem, ignore the IP Address Change and the Detach From WDS events if they occur immediately after a Roam event.

CSCef90440
|
Database exception while creating templates in multiple WLSE sessions.
|
When you try to create WLSE configuration templates in two separate browser windows simultaneously, one configuration template does not get saved.
To work around this problem, create templates in a single browser window at one time.
|
CSCsa35554
|
Weekly and monthly data aggregation does not happen at the beginning of the week/month.
|
The first weekly/monthly aggregation does not start at the beginning of the week/month. The first aggregation might happen earlier than the beginning of the week/month.
After the first weekly/monthly aggregation, all subsequent weekly/monthly aggregation occurs every 7 days for weekly or every 30 days for monthly aggregation from the first time the aggregation occurred.
There is no workaround to this problem.
|
CSCsa39854
|
WLSE deletes lines with "!" in the template.
|
If you have an exclamation point (!) in the IOS command line interface (for example, snmp-server community pub!!lic RO), WLSE deletes the lines with the "!" character when importing the configuration or when the archived configuration file containing the "!" character is exported as a configuration template.
To work around this problem, edit the custom command section of the template by manually adding the lines containing the "!" character.
|
CSCsa41193
|
Archive shows the type as Non-IOS and exporting the template fails.
|
If you have a pound sign (#) in the IOS configuration, for example, snmp-server community pub#lic ro, and you select Configure > Archives > View Archive and select Export to Template, the job fails and you get an error message. The View Archive screen shows the type as non- IOS even for APs running IOS images.
There is no workaround to this problem.
|
CSCeg84720
|
The AP 1210 automanage criteria needs a change from 2.7 to 2.9.
|
During an upgrade from Release 2.7 to 2.9, the AP 1210 Device Type auto-manage criteria will not work for AP 1210 devices with a single radio.
In the WLSE 2.9 release, AP 1210 device type criteria will match with devices with a dual radio only. There is a new criteria defined for AP 1210 devices with single radio AP 1210-SR.
To work around this problem, Edit the auto manage criteria for the auto manage template to include both AP 1210 (for dual radio) as well as AP 1210-SR (for single radio) device types.

Template GUI does not check for incompatible encryption type.
|
Under Configure > Templates > Security > SSID 802.11b/g/a, when you enter the Authenticated Key Management options as WPA or CCKM, without configuring the Encryption Modes option as Ciphers under Configure > Templates > Security > WEP 802.11b/g/a., the device reports the following error: Dot11Radio0 Error: Encryption mode cipher is not configured.
|
CSCeg17204
|
Incorrect CLI command is generated when AAA group name has space characters.
|
When the AAA group server name contains spaces, for example "aaa group server radius rad_eap" instead of "rad_eap" the following incorrect CLI command is generated:
aaa group server radius aaa group server radius rad_eap
The correct group name should be "rad_eap" to generate the following CLI command:
aaa group server radius rad_eap
|
CSCeg46839
|
WLSE autonegotiating even with speed/duplex hard coded.
|
The WLSE cannot detect a full duplex setting on the switch port, falls back to a half duplex setting, and causes a duplex mismatch.
|
CSCeg55064
|
Verifier check for AP registration with HSRP WDS needs fix.
|
Under Location Manager the AP's registration is checked for AP-WDS and non-redundant WLSM-WDS.
However, it does not check HSRP for redundant WLSM-WDS correctly.
|
CSCeg55576
|
Radio Management will not function when an AP is replaced with a different model but the same IP.
|
If an AP is replaced with a new AP of a different model, but using the same IP address, the old device (which has a different MAC address than the new one) shows up under "Duplicate IP" devices. If "daemons.log" is opened in WLSE under Admin > Appliance > Status > View Log File, the following exceptions are seen:
java.lang.ClassCastException: com.cisco.swan.co.EthernetInterface
at com.cisco.swan.nmif.DeviceRelationManager.processDevice(DeviceRelationManager.java:134)

EAP Username is missing in client reports.
|
The EAP username column is missing from the client reports.
|
CSCsa35793
|
After using the command no http-server accept <ip> <mask>, WLSE redundancy fails.
|
When you issue the command line interface commands http-server accept <ip> <mask> and no http-server accept <ip> <mask>, then the server will block HTTP access.
If the server has redundancy configured, then the server will remain in a starting state indefinitely because the HTTP access is blocked.
HTTPS access will still function and the redundancy feature can be disabled.
|
CSCsa36237
|
WLSE aborts active TFTP upgrade when per device timeout expires.
|
When the WLSE tries to push a firmware image to an AP over a WAN connection, sometimes the firmware job fails. This is due to an insufficient default timeout value for "Per device job operation timeout," which is set to 600 seconds under the Firmware > Advanced Parameters.
With the "Per device job operation timeout" value increased to 7200 seconds, there is enough time for a firmware upgrade for each device over a WAN connection.
|
CSCsa36862
|
An IOS template with dual radio configuration fails for APs with single radio, such as AP 1210.
|
An IOS configuration template containing configurations for both radio 11b/g and radio 11a fails when applied to dual radio capable APs such as the 1210 with single radio.
|
CSCsa36966
|
Images import for AP350 and AP1200 missing 12.05 link.
|
The firmware images for version 12.05 are not listed for AP350 and AP1200 devices when you try to import from Cisco.com.
|
CSCsa37758
|
Need to find root cause analysis of why /opt is getting 100% full.
|
The /opt partition in WLSE fills up with database dump files which prevents proper operation of the WLSE.
|
CSCsa38974
|
QoS policies with WMM generate CLI with DISAB.
|
When you create a new Services: QoS Policies 802.11b/g template under Configure > Templates > IOS, if DISAB appears in the Transmit Opportunity column, you cannot apply the template to any devices.
|
CSCsa39508
|
AAA reports should report meaningful information when no records are returned.
|
If you do not enable AAA server response time under Faults > Manage Faults the following message is shown for AAA under Reports > Trends: INFO: Graph will be available only after inventory runs twice.
The error message needs to provide the steps to correct the problem.
|
CSCsa39732
|
Switches, when pointed at, highlight the radio port information.
|
If you select Reports > Current > Device Type > Switches and point your cursor at the switches in that group, radio port information is displayed. The switches do not have radio ports and this information should not be displayed.
|
CSCsa39738
|
A non-IOS template with Receive Antenna as diversity gives error message.
|
When you create a non-IOS template by selecting the 11b Radio Hardware, and select Receive Antenna as Diversity, then save the template, the following error message appears:
Following key-value(s), in the current configuration template, are not supported:
Key: dot11CurrentRxAntenna.2
Value: diversity
|
CSCsa42074
|
TACACS server configuration is not supported by WLSE
|
When you try to save your IOS TACACS+ server configuration, the WLSE displays the following error:
Error processing configuration / No valid device versions supported.
|
CSCsa42391
|
Standby WLSE can take over the VIP address.
|
When you have redundant WLSEs, and you Telnet or log in using VIP address, you might access the standby rather than the active WLSE.
|
CSCsa42474
|
Image push using SNMP is not successful.
|
Using an incompatible image naming convention causes the upload to fail and erases the flash. A validation while importing the image from desktop or while editing the image details needs to check if the image name is in the proper format.
|
CSCsa44285
|
The 3560 switches are not yet supported in WLSE 2.9.
|
When these switches are not supported in WLSE, the WLSE does not contain any information about them.
Without this, there is no provision in WLSE to indicate which APs are connected to which switch.
|
CSCsa45411
|
Lost standby message sent out during data synchronization.
|
In a redundant operation, where the standby WLSE response is slow during data synchronization, the active WLSE might not get a response in the required time and it will send out a "lost standby" message.
|
CSCsa46081
|
Self-healing sometimes triggered when no radio has failed.
|
Self Healing may be triggered on a radio that is in fact operational. Self Healing monitors a radio by using other radios in the same building to validate that the monitored radio is transmitting. Some false healing may occur in dense deployments or those experiencing interference.
For self-healing to work satisfactorily, the monitored APs on a floor should have at least two other APs (vouching APs) in the building such that the vouching APs can hear the monitored AP reliably and consistently.
If a monitored AP has only one other AP that fluctuates between being able and not able to hear the monitored radio, self healing compensation (and fault) will occur.
Either the radio should have at least two radios that can hear its beacons or none. In the case of none then we will monitor the AP via the WDS registration. This issue is when a monitored AP fluctuates between being heard and not being heard. Interference can cause this as well.
|
CSCsa46147
|
Redundancy email address cannot contain hyphens.
|
The email address used to for notifications in a redundant WLSE environment cannot contain a hyphen '-' in the hostname portion of the address.
|
CSCsa46167
|
With 2 APs reporting about a rogue, the WLSE reports the rogue location incorrectly.
|
For rogue detection to work properly, the following are critical pre-requisites:
•All APs must be running software version 12.2(15)JA or later
•On a per floor basis, there needs to be an adequate number of APs for Radio Management tasks (in addition to serving wireless clients)
•Floor plan information must be accurate
When the pre-requisites are not met, the results can be skewed.
For example, when only two APs report the existence of a rogue AP, the WLSE incorrectly indicates, with a 90 to 100% certainty, its the rogue's location.
When more than two APs report the rogue's presence, the results are more accurate as to the location of the rogue AP.
|
CSCsa46173
|
Participating clients have too many additional lines in ad-hoc networks.
|
When you select Faults > Display Faults, then view the "Ad-hoc network creation detected" fault, a list of participating clients (if available) is shown.
One hundred lines are shown when you display this page, even if only 50 participating clients are listed.
|
CSCsa47230
|
An AAA server added to the wlse shows up as %hostname%.
|
After adding an AAA server to the WLSE, it appears as %hostname% in various UI displays in the WLSE (Reports, Devices, etc.).
|
CSCsa47363
|
The WLSE is not sending WEP commands to multiple devices.
|
When a template containing WEP key configuration is uploaded to multiple devices, only one device receives the configuration. However, all the other commands in the template are applied to all the devices.
|
CSCsa48103
|
No old record deletion from radio management database tables.
|
The radio management database records are not deleted which could fill the disk with records.
|
CSCsa52814
|
WLSE 2.9 email notification may not work after upgrade
|
Although faults are displayed under Faults > Display Faults, email notifications of those faults may not be sent.
|
CSCsa53633
|
Admin Access configuration should be sent last.
|
When you use the following templates:
•Configure > Template > Security > Server Manager
•Configure > Template > Security > Admin Access
the access point becomes inaccessible because the Server Manager configuration overwrites the Admin Access commands.
|
CSCsa63599
|
500 Error in Radio Monitor after upgrade to WLSE 2.9.1.
|
After upgrading to WLSE 2.9.1, a 500 error may occur when you select Radio Manager > Radio Monitoring.
