ECWmin must be no greater than ECWmax. The two parameters must be enabled or disabled
simultaneously.

When an AP uses 802.11b radio cards, it is recommended that you set TXOPLimit values of
AC-BK, AC-BE, AC-VI, and AC-VO to 0, 0, 188, and 102.
Examples
# Set AIFSN to 2 for AC-VO of APs.

Parameters
ac-vo
: Specifies AC-VO (voice traffic).
ac-vi
: Specifies AC-VI (video traffic).
all:
Specifies all the EDCA parameters.
cac
: Enables CAC on the client. AC-VO and AC-VI support CAC, which is disabled by default. AC-BE
and AC-BK do not support CAC.
aifsn-value
: AIFSN parameter of EDCA, which ranges from 2 to 15.
ecwmin-value
: ECWmin parameter of EDCA, which ranges from 0 to 15.
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 EDCA parameters of AC-VO or AC-VI for the clients in a
BSS.
Use the
undo wmm edca client
command to restore the default.
The following table lists the default EDCA parameters of AC-VI and AC-VO for clients.
