NOTE:
• 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 802.11
radio mode in the
network, H3C recommends the TXOPLimit parameters in Table 131.
• Once you enable CAC for an access cate
ory, it is enabled automatically for all hi
her 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.
