5. Click OK to accept Automatic/WMM as the Access Category. Wireless traffic is placed in the four queues

according to its 802.1p priority (default) or DSCP value.

Note that for each queue, four parameters are defined:

o AIFSN, Arbitration IFS Number, the default time before countdown.

o CW minimum (CWmin), the minimum contention window.

o CW maximum (CWmax), the maximum contention window.

o Transmit Ops (TXOP), the opportunity to transmit. This is the time during which a station that has won

the control of the shared medium can retain it.

For more information on WMM configuration on the WESM, please refer to ProCurve Application Note AN-

M12, Using 802.11e and WMM on the ProCurve Wireless Edge Services Module.

1. From the Settings Menu, open Network Profiles.

2. Edit the Network Profile you want to modify, using the Change button.

3. Choose 3. WLAN Configuration.

4. Choose 9. Call Power Save Mode.

5. Choose 1. U-APSD/PS-Poll and then Save.

6. Click Back several times to exit the different menus.
