Figure 4-33 Add Priority Mapping Entry

3.Select the 802.1p Priority (from 0-7) for 802.1d Priorities 0-7.

4.Click OK.

5.Click Add in the IP Precedence/DSCP ranges and 802.1d Priority table.

6.Select the IP DSCP Range for each 802.1d Priority.

7.Click OK.

NOTE: Changes to Priority Mapping require a reboot of the AP to take effect.

Enhanced Distributed Channel Access (EDCA)

WME uses Enhanced Distributed Channel Access, a prioritized CSMA/CA access mechanism used by WME-enabled clients/AP in a WME enabled BSS to realize different classes of differentiated Channel Access.

A wireless Entity is defined as all wireless clients and APs in the wireless medium contending for the common wireless medium. EDCA uses a separate channel access function for each of the Access Categories (Index) within a wireless entity. Each channel access function in a wireless entity that contends for the wireless medium as if it were a separate client contending for the wireless medium. Different channel access functions in a given Wireless Entity contend among themselves for access to the wireless medium in addition to contending with other clients.

STA EDCA Table and AP EDCA Table

This page is used to configure the client (STA) and AP Enhanced Distributed Channel Access (EDCA) parameters. You can modify the EDCA values for both Wireless A and Wireless B.

The EDCA parameter set provides information needed by the client stations for proper QoS operation during the wireless contention period. These parameters are used by the QoS enabled AP to establish policy, to change policies when accepting new stations or new traffic, or to adapt to changes in the offered load. The EDCA parameters assign priorities to traffic types where higher priority packets gain access to the wireless medium more frequently than lower priority packets.

NOTE: Default recommended values for EDCA parameters have been defined; Proxim recommends not modifying EDCA parameters unless strictly necessary.
