Table 73 Default EDCA parameters for clients
AC TXOP Limit AIFSN ECWmin ECWmax
AC-BK 0 7 4 10
AC-BE 0 3 4 10
AC-VI 94 2 3 4
AC-VO 47 2 2 3
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 are 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.
