Total received frames from wireless: The total number of frames received
from the wireless medium. The count includes data frames as well as control
and wireless management frames. The count does not include bad frames and
duplicate frames. For a description of these frames, refer to Bad frames
received and Duplicate frames discarded below.
Total received data frames: The total number of data frames received from
the wireless medium, including duplicate frames. Refer to Duplicate frames
discarded below.
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 section 4.2.6.5.9.
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.
