Low Priority Traffic Minimum Percent
When an SU with an SW version below 4.0 tries to associate with an AU that has
the Wireless Link Prioritization feature enabled, 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.
The Wireless Link Prioritization Parameters menu includes the following:
4.2.6.6.3.6.1 Wireless Link Prioritization Option
The Wireless Link Prioritization Option enables or disables the Wireless Link
Prioritization feature.
The default option is Disable.
4.2.6.6.3.6.2 Low Priority AIFS
The Low Priority AIFS defines the AIFS number of time slots that will be used by
the AU and the SUs served by it for low priority traffic.
The range is from 3 to 50 (time slots).
The default is 3.
4.2.6.6.3.6.3 Number of HW Retries for High Priority Traffic
The Number of HW Retries for High Priority Traffic defines the maximum number
of times that an unacknowledged high priority unicast packet can be
retransmitted. This is the value that will be used by the AU and by the SUs served
with it.
The range is from 1 to 14 times.
The default is 10 times.
4.2.6.6.3.6.4 Number of HW Retries for Low Priority Traffic
The Number of HW Retries for Low Priority Traffic defines the maximum number
of times that an unacknowledged low priority unicast packet can be
retransmitted. This is the value that will be used by the AU and by the SUs served
with it.
CAUTION
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.
