Devices FAQs and Troubleshooting
Symptom After creating a customized device name format, truncation of device names in displays such
as device trees makes it difficult or impossible to distinguish one device from another.
Possible Cause In device trees, only 30 characters can be displayed.
Recommended Action Reconstruct the device identifier string so that the unique portion of the name
comes first; for example, place the IP address first.
Symptom Instead of a proper device name or IP address, the WLSE is displaying device names as
%dns%, %hostname%, or %description%.
Possible Cause The default device identifier used by the WLSE in its displays is the device’s
hostname. If no hostname is assigned to the device, %hostname% is used instead. For the %dns%
or %description% name, a user has changed the default device identifier but there is no DNS name
or the user has not assigned a description. The default device identifier string is set under Devices >
Discover > DISCOVER > Advanced Options.
Recommended Action If you use the IP address as the default identifier, the device name display will
always be correct. For more information, see the online help or the User Guide for the CiscoWorks
Wireless LAN Solution Engine, Release 2.13 on Cisco.com.
Symptom After a device is moved from unmanaged to managed, the name format is not applied.
Possible Cause When devices are moved from unmanaged to managed, the current name format
choice is not applied until the next inventory runs.
Recommended Action Run an inventory on the device. Select Devices > Discover > Inventory > Run
Inventory.
Symptom The IP address of a device was changed, but the Device Details display does not reflect this
change.
Possible Cause The device tree under MANAGED DEVICES shows the state of the system at the
time you select the Managed Devices option. Therefore, if device details change or the device
changes to another state after you display the page, these changes not automatically displayed.
Recommended Action If you refresh the page from the browser or navigate to another page and then
return to Managed Devices, the page will be updated to show changes that have occurred.
Symptom When trying to discover a WLSM, the error message “device is not supported” is listed in the
discovery log.
Possible Cause WLSM does not support CDP and cannot be discovered by using the regular
discovery job mechanism
Recommended Action None. WLSM will be discovered through WLCCP, as long as WDS is properly
configured. For more information on configuring WDS for the WLSM, see the document
Configuring Devices for Management by the CiscoWorks Wireless LAN Solution Engine on
