Access category TXOP Limit AIFSN ECWmin ECWmax
AC-BE 0 3 4 6
AC-VI 94 1 3 4
AC-VO 47 1 2 3
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
1. Select QoS > Wireless QoS from the navigation tree.
By default, the Wireless QoS tab is displayed.
2. Click the icon in the Operation column for the desired AP.
3. On the client EDCA list, click the icon in the Operation column for the desired priority type
(AC_BK, for example).
