The Burst Interval, which defines the maximum duration of a burst, should be set
to a lower value for delay sensitive traffic. Typically the Burst Interval of the AU
should be set to higher value than that of the SUs, because of the higher number
of packets that should be transmitted by the AU.
When the Wireless Link Prioritization feature is enabled, the following
Performance parameters are not applicable:
 AIFS
 Number of Hardware Retries
 Burst Mode Option
 Burst Interval
When an SU with a SW version below 4.0 tries to associate with an AU that has
the Wireless Link Prioritization feature enable, the AU will generate a trap that will
include information about this SU. In this way the system administrator can be
alerted that the SU should be upgraded. This is necessary because otherwise an
SU that does not support the Wireless Link Prioritization feature will send all the
traffic as high priority.
NOTE
Verify that all SUs served by an AU with the Wireless Link Prioritization Option enabled use a SW
version that supports this feature (SW version 4.0 and higher). Otherwise, overall performance and
quality of service in the cell may be reduced since all data from an SU with SW version below 4.0
will be sent with high priority.
