Access Point Faults

Table 2-1 Access Point Faults 

Fault Description	Type	Explanation	Related Setting	Recommended Action
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 > Registration Error	Verify that the WLCCP AP credentials are configured correctly so that the AP can register with a WDS in its subnet. For more information, see the managing devices information in the online help or the User Guide for the CiscoWorks Wireless LAN Solution Engine, Release 2.7.
AP registered with an Unmanaged WDS: ipAddressOfTheUnManagedWDS	IOS	AP is registered with a WDS but that WDS is not managed by WLSE. When this fault is cleared, the following message displays: AP registered with a managed WDS.	Manage Fault Settings > Access Point > Registration Error	Manage the WDS.

Manage Fault Settings > Access Point Policies > Key Rotation per VLAN	Log in to the access point and enable the broadcast key rotation interval.
Device state is rogue access point	IOS	The WLSE detected a rogue access point. (This is an access point that is not being managed and is unknown to the WLSE.)	Manage Network-Wide Settings > Rogue AP Detection	Use Location Manager to locate the rogue access point.
Device was not reachable via SNMP	Non-IOS and IOS	The SNMP Agent could be down. When this fault is cleared, the following message displays: Device was reachable via SNMP.	Manage Fault Settings > Access Point Thresholds > SNMP Reachable	Make sure SNMP is enabled on the device and that the agent is not down. Take a MIB walk of the device to make sure sysup time is returning 0, which indicates Device is reachable.
		The SNMP community string in the access point has been changed, and then a discovery job is run.	Not applicable.	Change the SNMP community string on the WLSE to match the new community string on the access point, then run discovery again.
Duplicate IP is found	Non-IOS and IOS	WLSE discovery detects a second device with the same IP address in the network. When this fault is cleared, the following message displays: Duplicate IP is not found.	Manage Fault Settings > Access Point Policies > DuplicateIP Status	Do one of the following: •Assign a new IP address to the device. •If you have substituted a device for the device with the same IP, and want to continue to use that IP, then delete the original device, and run discovery again.
		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.		Delete the device, and run discovery again.
EAP per SSID for Mixed Supplicant is disabled	Non-IOS and IOS	The Network EAP or the Open authentication is disabled on this SSID. When this fault is cleared, the following message displays: EAP per SSID for Mixed Supplicant is enabled.

If the threshold is set correctly, review your network to determine the action necessary to clear the fault condition.
Ethernet bandwidth utilization is Overloaded (utilization %)	Non-IOS and IOS	The fault threshold set for the overloaded state has been exceeded. When this fault is cleared, the following message displays: Ethernet bandwidth utilization is OK.	Manage Fault Settings > Access Point Thresholds > Ethernet Port Utilization	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.

When this fault is cleared, the following message displays: HotStandBy is disabled.	Manage Fault Settings > Access Point Policies > HotStandby Status	For non-IOS access points: 1. Check the primary access point, the Ethernet port, or the Radio port to see why the hot standby access point has been activated. 2. Correct the condition. For example, if the Radio Port on the formerly active access point was in a disabled state, then enable it using the access point GUI. 3. Launch the GUI for access point that is currently in Active Takeover mode. 4. Select the Hot Standby section and click Start Hot Standby mode to reconfigure the access point to Hot Standby mode.
				For IOS access points: 1. Check the primary access point, the Ethernet port, or the Radio port to see why the hot standby access point has been activated. 2. Correct the condition.
