Total Tx events: The total number of transmit events. Typically,
transmission events include cases where transmission of a frame
was delayed or was aborted before completion. The following
additional counters are displayed to indicate the reason for and the
nature of the event:
¾ 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.
¾ Delayed: The number of frames whose transmission was delayed
because they were in the queue for transmission when the SW
Retry mechanism was activated for a previous frame designated
to the same address. (refer to
Adaptive Modulation Algorithm
on
page 4-60 for more information)
¾ Underrun: The number of times that transmission of a frame
was aborted because the rate of submitting frames for
transmission exceeds the available transmission capability.
¾ Others: The number of frames whose transmission was not
completed or delayed 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 events: The total number of frames that were not received
properly. The following additional counters are displayed to indicate
the reason for the failure:
¾ Phy: The number of frames that were not received properly due
to a hardware problem.
¾ CRC: The number of frames received from the wireless media
containing CRC errors.
¾ Overrun: The number of frames that were discarded because the
receive rate exceeded the processing capability or the capacity of
the Ethernet port.
