About the Aironet Current Errors report

This home-level Wireless Errors dashboard report displays information about all wireless access point (WAP) transmit and receive errors. If the WAP includes support for multiple radios, for example, 802.11g and 802.11n devices, the error values for each radio are provided in a separate column.

You can also click the (WAP) device name link, at the top of the report, to access the Device Status Dashboard. For more information, see Understanding the Device Status dashboard.

If you use the WhatsUp Flow Monitor plug-in with WhatsUp Gold, you can click the icon to drill down into the Flow Monitor reports for specific source and destination information about the wireless device and its conversation partners.

The following wireless client information is available in this report by default:

• Station ID. The default value is the station's assigned, unique MAC address. The associated OID is 1.2.840.10036.1.1.1.1.
• Carrier Set. Lists the WAP radio frequencies that are in operation. The associated OID is 1.3.6.1.4.1.9.9.272.1.1.2.1.1.1.

Receive Errors

• ACK Failures. Lists the number of times the Transmission Control Protocol acknowledgement (ACK) is not received when expected. The associated OID is 1.2.840.10036.2.2.1.9.
• FCS Errors. Lists the number of times a Frame Check Sequence (FCS) error is detected in a received MAC Protocol data unit (MPDU). The associated OID is 1.2.840.10036.2.2.1.12.
• WEP Undecryptable. Lists the number of times a frame is received with the Wired Equivalent Privacy (WEP) subbox of the Frame Control box set to one and with the WEPOn value for the key mapped to the Transmitter's (TA's) MAC address. This indicates that the frame should not have been encrypted or that frame is discarded due to the receiving station (STA) not implementing the privacy option. The associated OID is 1.2.840.10036.2.2.1.14.
• Frame MAC CRC Errors. Lists the number of times a frame received has any Message Authentication Code cyclic redundancy check (MAC CRC) errors. The associated OID is 1.3.6.1.4.1.9.9.272.1.2.1.1.1.2.
• SSID Mismatches. Lists the number of times a beacon or probe response frame is received for which the Service Set Identifier (SSIDs) in the frame do not match any of the supported SSIDs. The associated OID is 1.3.6.1.4.1.9.9.272.1.2.1.1.1.3.

Transmit Errors

• Transmit Failed. Lists the number of times a MAC Service Data Unit (MSDU) is not transmitted successfully due to the number of transmit attempts exceeding either the dot11ShortRetryLimit or dot11LongRetryLimit. The associated OID is 1.2.840.10036.2.2.1.3.
• Single Retries. Lists the number of times a MAC Service Data Unit (MSDU) is successfully transmitted after one retransmission. The associated OID is 1.2.840.10036.2.2.1.4.
• Multiple Retries. Lists the number of times a MAC Service Data Unit (MSDU) is successfully transmitted after one or more retransmissions. The associated OID is 1.2.840.10036.2.2.1.5.
• Deferred Energy Detect Errors. Lists the number of times a frame transmission is deferred due to energy detection errors. The associated OID is 1.3.6.1.4.1.9.9.272.1.2.1.1.1.1.
