R2511-HP MSR Router Series WLAN Command Reference(V5)

noack: Specifies the AC queue to use the No ACK policy. The protocol defines two ACK policies: Normal
ACK and No ACK.
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. The range of this
argument is limited by the radio chip capability.
ecwmin-value: ECWmin parameter of EDCA, which ranges from 0 to 15. The range of this argument is
limited by the radio chip capability.
ecwmax-value: ECWmax parameter of EDCA, which ranges from 0 to 15. The range of this argument is
limited by the radio chip capability.
aifsn-value: AIFSN parameter of EDCA, which ranges from 1 to 15. The range of this argument is limited
by the radio chip capability.
Usage guidelines
For description on each EDCA parameter, see WLAN Configuration Guide.
ECWmin must be no greater than ECWmax. The two parameters must be enabled or disabled
simultaneously.
When an AP uses 802.11b radio cards, HP recommends that you set TXOPLimit values of the AC-BK,
AC-BE, AC-VI, and AC-VO queues to 0, 0, 188, and 102, respectively.
Examples
# Set AIFSN to 2 for the AC-VO queue of the radio.
<Sysname> system-view
[Sysname] interface WLAN-Radio2/0
[Sysname-WLAN-Radio2/0] wmm edca radio ac-vo aifsn 2
wmm edca client (ac-vo and ac-vi)
Use wmm edca client to set EDCA parameters for the AC-BE or AC-BK queue for clients.
Use undo wmm edca client to restore the default of the specified or all EDCA parameters for the specified
AC queue.
Syntax
wmm edca client { ac-vo | ac-vi } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax
ecwmax-value | txoplimit txoplimit-value | cac } *
undo wmm edca client { ac-vo | ac-vi } { aifsn | ecw | txoplimit | cac | all }
Default
The following table lists the default EDCA parameters of the AC-VI and AC-VO queue for clients.
