 Total Rx events: The total number of frames that were not received properly.
The following additional counters are displayed to indicate the reason for the
failure:
» Phy: The number of Phy errors (unidentified signals).
» CRC: The number of frames received from the wireless medium containing
CRC errors.
» Overrun: The number of frames that were discarded because the receive
rate exceeded the processing capability or the capacity of the Ethernet
port.
» Decrypt: The number of frames that were not received properly due to a
problem in the data decryption mechanism.
» Other
 Total received concatenated frames: The total number of concatenated
frames received from the wireless medium, including duplicate frames. There
are also separate counts for concatenated frames that include one frame
(Single), two frames (Double) or more than two frames (More). For more details
refer to “Concatenation Parameters” on page 174
 Bad fragments received: The number of fragments received from the wireless
medium containing CRC errors.
 Duplicate frames discarded: The number of data frames discarded because
multiple copies were received. If an acknowledgement message is not received
by the originating unit, the same data frame can be received more than once.
Although duplicate frames are included in all counters that include data
frames, only the first copy is forwarded to the Ethernet port.
 Internally discarded MIR\CIR: The number of data frames received from the
Ethernet port that were discarded by the MIR/CIR mechanism to avoid
exceeding the maximum permitted information rate.
 TX retransmission %: The percentage of frames that were not transmitted
properly and had to be retransmitted.
 TX CRC %: The percentage of Cyclic Redundancy Check errors that occurred
over the air link.
