♦ Total Tx errors: The total number of transmit errors. The following
additional counters are displayed to indicate the reason for the failure:
Excessive Retries (Exces RTx): The number of dropped frames,
which are the frames unsuccessfully retransmitted until the
maximum permitted number of retransmissions without being
acknowledged.
Filtered: .
Underrun: The number of frames that were aborted because the
rate of submitting frames for transmission exceeds the available
transmission capability.
Other: The number of frames that were not transmitted due to a
problem other than those represented by the other counters.
♦ Total received frames from wireless: The total number of frames
received from the wireless media. 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 data frames
received from the wireless media, including duplicate frames. Refer to
Duplicate frames discarded below.
♦ Total Rx errors: 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 frames that were not received properly due to a
hardware problem.
CRC: The number of frames received from the wireless media
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.
Other: The number of frames that were not received properly due to
a problem other than those represented by the other counters.
♦ Bad frames received: The number of frames received from the wireless
media 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.
