Syntax
wmm edca client { ac-be | ac-bk } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax

undo wmm edca client { ac-be | ac-bk }
Default
The default EDCA parameter values of AC-BE or AC-BK queues for clients are shown in Table 14.

Parameters
ac-be: Specifies the AC-BE (best-effort traffic) queue.
ac-bk: Specifies the AC-BK (background traffic) queue.
aifsn aifsn-value: Specifies the arbitration inter-frame spacing number (AIFSN), in the range of 1 to
15.
ecwmin ecwmin-value: Specifies the exponent form of CWmin (ECWmin), in the range of 0 to 15.
ecwmax ecwmax-value: Specifies the exponent form of CWmax (ECWmax), in the range of 0 to 15.
The value of ECWmax cannot be smaller than the value of ECWmin.
txoplimit txoplimit-value: Specifies the transmission opportunity limit (TXOP Limit) value, in the
range of 0 to 65535 (in units of 32 microseconds). If the value is 0, a client can send only one packet
each time it holds the channel.
Usage guidelines
As a best practice, set the TXOP Limit value to 0 for both the AC-BE and AC-BK queues if all the
clients are 802.11b clients.
As a best practice, use the default TXOPLimit values for both the AC-BK and AC-BE queues if both
802.11b and 802.11g clients exist in the WLAN.
Examples
# Set the AIFSN to 5 for the AC-BE queue.
<Sysname> system-view
[Sysname] interface wlan-radio 0/1
[Sysname-WLAN-Radio0/1] wmm edca client ac-be aifsn 5
wmm edca client (ac-vi and ac-vo)
Use wmm edca client to set EDCA parameters of AC-VI or AC-VO queues for clients.
