ROGUE_AP_DETECTED

May be a security issue.Use maps and trends to investigate.

ROGUE_AP_REMOVED

Detected rogue access point has timed out. The unit might have shut down or moved out of the coverage area.

AP_MAX_ROGUE_COUNT_EXCEEDED

The current number of active rogue access points has exceeded system threshold.

LINK_UP

Positive confirmation message.

LINK_DOWN

Port may have a problem or is administratively disabled.

LINK_FAILURE

Port may have a problem or is administratively disabled.

AUTHENTICATION_FAILURE

Attempted security breech. Investigate.

STP_NEWROOT

Informational message.

STP_TOPOLOGY_CHANGE

Informational message.

IPSEC_ESP_AUTH_FAILURE

Check WLAN IPSec configuration.

IPSEC_ESP_REPLAY_FAILURE

Check for attempt to spoof IP Address.

IPSEC_ESP_POLICY_FAILURE

Check for IPSec configuration mismatch between WLAN and client.

IPSEC_ESP_INVALID_SPI

Informational message.

IPSEC_OTHER_POLICY_FAILURE

Check for IPSec configuration mismatch between WLAN and client.

IPSEC_IKE_NEG_FAILURE

Check for IPSec IKE configuration mismatch between WLAN and client.

IPSEC_SUITE_NEG_FAILURE

Check for IPSec IKE configuration mismatch between WLAN and client.

IPSEC_INVALID_COOKIE

Informational message.

RADIOS_EXCEEDED

Maximum number of supported Cisco Radios exceeded. Check for controller failure in the same Layer 2 network or add another controller.

SENSED_TEMPERATURE_HIGH

Check fan, air conditioning and/or other cooling arrangements.

SENSED_TEMPERATURE_LOW

Check room temperature and/or other reasons for low temperature.

TEMPERATURE_SENSOR_FAILURE

Replace temperature sensor ASAP.

TEMPERATURE_SENSOR_CLEAR

Temperature sensor is operational.

POE_CONTROLLER_FAILURE

Check ports — possible serious failure detected.

MAX_ROGUE_COUNT_EXCEEDED

POWER_SUPPLY_CHANGE

Check for power-supply malfunction.

COLD_START

Cisco Wireless LAN Controller may have been rebooted.

WARM_START

Cisco Wireless LAN Controller may have been rebooted.

The Radios associated with Controller A.B.C.D1 exceeded license count of 36. The current number of radios on the controller is 36.

Indicates the user is trying to add more access points than the license count allows.

1 A.B.C.D represents the controller MAC address.


Using Client Reason and Status Codes in Trap Logs

The WCS Clients > Detail page lists the reason and status codes that you are likely to encounter when reviewing the trap logs. Table D-2 lists client reason codes and descriptions. Table y lists client status codes and descriptions.
