! Total submitted frames (bridge): The total number of data frames
submitted to the internal bridge for transmission to the wireless
media. The count does not include control and wireless
management frames, or retransmissions. There are also separate
counts for each priority queue to which the frames were routed,
which are High, Mid and Low (currently the High queue is not used
for data frames).
! Frames dropped (too many retries): The number of dropped
frames, which are the frames unsuccessfully retransmitted until the
maximum permitted number of retransmissions without being
acknowledged. 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 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 the frames
unsuccessfully retransmitted until the maximum permitted
number of retransmissions without being acknowledged.
# 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 4-81 for more information)
# 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.
! 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.
