Chapter 4 - Operation and Administration

an SU that does not support the Wireless Link Prioritization feature will send all the traffic as high priority.

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.

The Wireless Link Prioritization Parameters menu includes the following:
