Error and Event Messages


This appendix lists the CLI error and event messages.

Association Management Messages

Error Message    DOT11-3-BADSTATE: [mac-address] [chars] [chars] -> [chars]

Explanation    802.11 Association and management uses a table-driven state machine to keep track and transition an Association through various states. A state transition occurs when an Association receives one of many possible events. When this error occurs, it means that an Association received an event that it did not expect while in this state.

Recommended Action    The system can continue but may lose the Association that generates this error. Copy the message exactly as it appears and report it to your technical service representative.

Error Message    DOT11-6-ASSOC: Interface [interface], Station [char] [mac] Associated

Explanation    A station associated to an access point.

Recommended Action    None.

Error Message    DOT11-6-ADD: Interface [interface], Station [mac] Associated to Parent 
[mac]

Explanation    A station associated to an access point.

Recommended Action    None.

Error Message    DOT11-6-DISASSOC: Interface [interface], Deauthenticating Station 
[mac] [char]

Explanation    A station disassociated from an access point.

Recommended Action    None.

Error Message    DOT11-6-ROAMED: Station [mac-address] Roamed to [mac-address]

Explanation    A station roamed to a new access point.

Recommended Action    None.

Error Message    LEAPCL-3-FAILED: AP Authentication to the WDS failed

Explanation    The access point failed to authenticate to the WDS device because the username or password were incorrect.

Recommended Action    Correct the username and password configuration on either the access point or the authentication server.

Error Message    LEAPCL-3-TIMEOUT: AP Timed out authenticating to the WDS

Explanation    The access point failed to authenticate to the WDS device in the required time.

Recommended Action    None.

802.11 Subsystem Messages

Error Message    DOT11-6-FREQ_INUSE: Radio frequency [int] is in use

Explanation    When scanning for an unused frequency, the unit recognized another radio using the displayed frequency.

Recommended Action    None.

Error Message    DOT11-6-FREQ_USED: Radio frequency [int] selected

Explanation    After scanning for an unused frequency, the unit selected the displayed frequency.

Recommended Action    None.

Error Message    DOT11-4-NO_SSID: No SSIDs configured, radio not started

Explanation    All SSIDs were deleted from the configuration. At least one must be configured for the radio to run.

Recommended Action    Configure at least one SSID on the access point.

Error Message    DOT11-4-LOADING_RADIO: Interface [interface] loading the radio 
firmware ([chars])

Explanation    The radio has been stopped to load new firmware.

Recommended Action    None.

Error Message    DOT11-2-RADIO_FAILED: Interface [interface] failed — [chars]

Explanation    The radio driver found a severe error and is shutting down.

Recommended Action    None.

Error Message    DOT11-4-LINK_DOWN: Radio parent lost: [chars]

Explanation    The connection to the parent access point was lost for the displayed reason. The unit will try to find a new parent access point.

Recommended Action    None.

Error Message    DOT11-4-CANT_ASSOC: Cannot associate: [chars]

Explanation    The unit could not establish a connection to a parent access point for the displayed reason.

Recommended Action    Verify that the basic configuration settings (SSID, WEP, and others) of the parent access point and this unit match.

Error Message    DOT11-4-MAXRETRIES: Packet to client [mac] reached max retries, remove 
the client

Explanation    A packet sent to the client has not been successfully delivered many times, and the max retries limit has been reached. The client is deleted from the association table.

Recommended Action    None.

Error Message    DOT11-AUTH_FAILED: Station [mac-address] authentication failed

Explanation    The station failed authentication. Severity level: 7.

Recommended Action    Verify that the user entered the correct username and password, and check that the authentication server is online.

Error Message     Severity level: 7.DOT11-TKIP_MIC_FAILURE: TKIP Michael MIC failure was 
detected on a packet (TSC=0x0) received from [mac-address]

Explanation    TKIP Michael MIC failure was detected on a unicast frame decrypted locally with the pairwise key. Severity level: 4.

Recommended Action    A failure of the Michael MIC in a packet usually indicates an active attack on your network. Search for and remove potential rogue devices from your wireless LAN.

Error Message    DOT11-TKIP_MIC_FAILURE_REPORT: Received TKIP Michael MIC failure 
report from the station [mac-address] on the packet (TSC=0x0) encrypted and 
protected by [key] key

Explanation    The access point received an EAPOL-key from a station notifying the access point that TKIP Michael MIC failed on a packet transmitted by this access point. Severity level: 4.

Recommended Action    None.

Error Message    DOT11-TKIP_MIC_FAILURE_REPEATED: Two TKIP Michael MIC failures were 
detected within [number] seconds on [interface] interface. The interface will be 
put on MIC failure hold state for next [number] seconds

Explanation    Because MIC failures usually indicate an active attack on your network, the interface will be put on hold for the configured time. During this hold time, stations using TKIP ciphers are disassociated and cannot reassociate until the hold time ends. At the end of the hold time, the interface operates normally. Severity level: 3.

Recommended Action    Michael MIC failures usually indicate an active attack on your network. Search for and remove potential rogue devices from your wireless LAN. If this is a false alarm and the interface should not be on hold this long, use the countermeasure tkip hold-time command to adjust the hold time.

Error Message    Multicast received for AP sa [mac-address], da [mac-address], ra 
cbcb.cbcb.cbcb ta [mac-address]

Explanation    The access point received a direct broadcast/multicast frame in which the dot11 MAC header's RA address field is a broadcast/multicast address.

Recommended Action    None. However, if your access point displays this message frequently, capture these frames with a sniffer for further analysis.

Recommended Action   

Inter-Access Point Protocol Messages

Error Message    DOT11-6-ROAMED: Station [mac-address] Roamed to [mac-address]

Explanation    A station has roamed to a new access point.

Recommended Action    None.

Error Message    DOT11-STANDBY-REQUEST: Hotstandby request to shut down radios from 
[mac-address]

Explanation    A standby access point has requested this access point to shut down its radio interfaces because a failure has been detected on one of this access point's radio interfaces. Severity level: 6.

Recommended Action    None.

Severity level: 4. Severity level: 4.Local Authenticator Messages

Error Message    RADSRV-4-NAS_UNKNOWN: Unknown authenticator: [ip-address]

Explanation    The local RADIUS server received an authentication request but does not recognize the IP address of the network access server (NAS) that forwarded the request.

Recommended Action    Make sure that every access point on your wireless LAN is configured as a NAS on your local RADIUS server.

Error Message    RADSRV-4-NAS_KEYMIS: NAS shared key mismatch.

Explanation    The local RADIUS server received an authentication request but the message signature indicates that the shared key text does not match.

Recommended Action    Correct the shared key configuration on either the NAS or on the local RADIUS server.

Error Message    RADSRV-4-BLOCKED: Client blocked due to repeated failed 
authentications

Explanation    A user failed authentication the number of times configured to trigger a block, and the account been disabled.

Recommended Action    Use the clear radius local-server user username privileged EXEC command to unblock the user, or allow the block on the user to expire by the configured lockout time.
