Alvarion BreezeNET B System Manual page 89

In addition, a summary table displays information about the Forwarding
Database (Bridging Info). The summary table includes the current number of
entries, the aging time specified by the Bridge Aging Time parameter and the
maximum number of entries permitted for this table, which is 1016.
4.2.5.5 Per Modulation Level Counters
The Per Modulation Level Counters display statistics relating to wireless link
performance at different radio modulation levels. The Per Modulation Level
Counters menu includes the following options:
Display Counters: Select this option to display the current values of the Per
Modulation Level Counters.
Reset Counters: Select this option to reset the Per Modulation Level
Counters.
The statistics show the number of frames accumulated in different categories
since the last reset.
The Per Modulation Level Counters display the following information for each
modulation level supported by the unit:
SUCCESS: The total number of successfully transmitted frames at the
applicable modulation level.
FAILED: The total number of failures to successfully transmit a frame during
a HW Retry cycle at the applicable rate.
In the RB, the Average Modulation Level (AML) is also displayed. This is the
average modulation level (rounded to the nearest integer) since the last time the
Per Modulation Level counters were reset. The average is calculated using the
SUCCESS count at each modulation level as weights.
4.2.5.6 Link Capability
The Link Capability option provides information on HW and SW capabilities of
relevant units. In a BU, the information provided in the Link Capability reports is
for the associated RB. In an RB, the Link Capability reports include information
on all BUs in the neighboring BUs table (all BUs with whom the RB can
communicate).
