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.
