ecwmax-value
: ECWmax parameter of EDCA, which ranges from 0 to 15.
txoplimit-value
: TXOPLimit parameter of EDCA, which ranges from 0 to 65535 (in units of 32
microseconds). The TXOP value of 0 indicates that only one MPDU can be transmitted.
Description
Use the
wmm edca client
command to set the set of EDCA parameters for the specified AC (AC-BE or
AC-BK) for clients.
Use the
undo wmm edca client
command to restore the default of the specified or all EDCA
parameters for the specified AC.
The following table lists the default EDCA parameter settings for AC-BK and AC-BE for clients.

ECWmin must not be greater than ECWmax. The two parameters must be enabled or disabled
simultaneously.
z
When all the clients are 802.11b terminals, it is recommended that you set the TXOPLimit value to
0 for both AC-BK and AC-BE.
z
If both 802.11b and 802.11g clients are present, it is recommended that you use the default
TXOPLimit settings for AC-BK and AC-BE.
