ECWmin cannot be greater than ECWmax.
If all clients operate in 802.11b radio mode, you are recommended to 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, the TXOPLimit parameters in Table 73 ar
e recommended.
Once you enable CAC for an AC, it is enabled automatically for all ACs with higher priority. 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.
