NOTE:

ECWmin cannot be greater than ECWmax.

On an AP operating in 802.11b radio mode, HP recommends that you set the TXOP-Limit to 0, 0, 188,
and 102 for AC-BK, AC-BE, AC-VI, and AC-VO.

Setting EDCA parameters for wireless clients

Configuration restrictions and guidelines

Follow these restrictions and guidelines when you set EDCA parameters for wireless clients:

ECWmin cannot be greater than ECWmax.

If all clients operate in 802.11b radio mode, set TXOPLimit to 188 and 102 for AC-VI and AC-VO.

If some clients operate in 802.11b radio mode and some clients operate in 802.11g radio mode in
the network, HP recommends the TXOPLimit parameters in

Table 231

.

Once you enable CAC for an access category, it is enabled automatically for all higher priority

access categories. For example, if you enable CAC for AC-VI, CAC is also enabled for AC-VO.
However, enabling CAC for AC-VO does not enable CAC for AC-VI.

Configuration procedure

By default, the Wireless QoS tab is displayed.

2.
