Management and Other Data frames, including successfully transmitted
unicast frames and multicast/broadcast data frames (excluding
retransmissions, excluding Beacons in AU)
Total Transmitted Unicasts (AU only): The number of unicast frames
successfully transmitted to the wireless medium, excluding retransmissions.
This count is useful for calculating the rates of retransmissions or dropped
frames, as only unicast frames are retransmitted if not acknowledged.
Total submitted frames (bridge): The total number of data frames submitted
to the internal bridge for transmission to the wireless medium. The count
does not include control and wireless management frames, or
retransmissions. There are also separate counts for each priority queue
through which the frames were routed (High, Mid and Low).
Frames dropped (too many retries): The number of dropped frames, which
are unsuccessfully retransmitted without being acknowledged until the
maximum permitted number of retransmissions. This count includes dropped
data frames as well as dropped control and wireless management frames.
Total retransmitted frames: The total number of retransmissions, including
all unsuccessful transmissions and retransmissions.
Total transmitted concatenated frames: The total number of concatenated
frames transmitted successfully to the wireless medium, excluding
retransmissions. 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
.
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:
Dropped: The number of dropped frames, which are unsuccessfully
retransmitted without being acknowledged until the maximum permitted
number of retransmissions.
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.
Others: The number of frames whose transmission was not completed or
delayed due to a problem other than those represented by the other
counters.
