Recommended Action
|
AP is in a Degraded state number associated clients
|
Non-IOS and IOS
|
The fault threshold set for the degraded state has been exceeded.
When this fault is cleared, the following message displays: AP is in OK state.
|
Manage Fault Settings > Thresholds > Access Point > Associated Clients
|
Verify that the fault threshold is set correctly.
If the threshold is set correctly, review your network to determine the action necessary to clear the fault condition.
|
AP is in an Overloaded state number associated clients
|
Non-IOS and IOS
|
The fault threshold set for the overloaded state has been exceeded.
When this fault is cleared, the following message displays: AP is in OK state.
|
Manage Fault Settings > Thresholds > Access Point > Associated Clients
|

If the threshold is set correctly, review your network to determine the action necessary to clear the fault condition.
|
AP is not registered with any WDS
|
IOS
|
The managed IOS access point is not registered with any WDS.
For Radio Manager functionality to work, all IOS access points must register with a WDS. If an access point is not registered, it will be excluded from all the Radio Manager procedures, which will provide incorrect results.
|
Manage Fault Settings > Access Point > Thresholds > Registration Error
|
Verify that the WLCCP credentials for wireless domain services (WDS) are configured correctly.
For more information, see the managing devices information in the online help or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.5.

|
When changing the MAC address of the FastEthernet interface to the MAC address of a radio interface, the WLSE might detect the access point as a duplicate device. This is because during discovery, the uniqueness of the device is based on its FastEthernet MAC address.
