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.

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 F-2 lists client reason codes and descriptions. Table y lists client status codes and descriptions.

Client Reason Codes

Table F-2 Client Reason Code Descriptions and Meanings
Client Reason Code	Description	Meaning
0	noReasonCode	Normal operation.
1	unspecifiedReason	Client associated but no longer authorized.
2	previousAuthNotValid	Client associated but not authorized.
3	deauthenticationLeaving	The access point went offline, deauthenticating the client.
4	disassociationDueToInactivity	Client session timeout exceeded.
5	disassociationAPBusy	The access point is busy, performing load balancing, for example.
6	class2FrameFromNonAuthStation	Client attempted to transfer data before it was authenticated.
7	class2FrameFromNonAssStation	Client attempted to transfer data before it was associated.
8	disassociationStaHasLeft	Operating System moved the client to another access point using non-aggressive load balancing.
9	staReqAssociationWithoutAuth	Client not authorized yet, still attempting to associate with an access point.
99	missingReasonCode	Client momentarily in an unknown state.

Client Status Codes

Using Lightweight Access Point LEDs

Table F-3 Client Status Code Descriptions and Meanings
