behind other BreezeACCESS 4900 units), is sent to the High queue, regardless of

the priority configuration.

The Wireless Link Counters include the following statistics:

 Total transmitted frames to wireless: The number of frames transmitted to

the wireless medium. The total includes one count for each successfully

transmitted unicast frame (excluding retransmissions), and the number of

transmitted multicast and broadcast frames, including control and wireless

management frames. In the AU, there are also separate counters for the

following:

» Beacons (AU only)

» 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 “Concatenation Parameters” on page 174.
