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

96
Default command level
2: System level
Parameters
ac-vo: Specifies the AC-VO (voice traffic) queue.
ac-vi: Specifies the AC-VI (video traffic) queue.
all: Specifies all the EDCA parameters.
cac: Enables CAC. The AC-VO and AC-VI queues support CAC, which is disabled by default. The AC-BE
and AC-BK queues 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.
Usage guidelines
For description on each EDCA parameter, see WLAN Configuration Guide.
ECWmin must not be greater than ECWmax. The two parameters must be enabled or disabled
simultaneously.
When all the clients are 802.11b terminals, HP recommends that you set the TXOPLimit to 188 and 102
for the AC-VI and AC-VO queues, respectively.
If both 802.11b and 802.11g clients are present, HP recommends that you use the default TXOPLimit
settings in Table 24.
If CA
C is enabled for an AC queue, CAC is also enabled for AC queues with higher priority. For example,
if you use the wmm edca client command to enable CAC for the AC-VI queue, CAC is also enabled for
the AC-VO queue. However, enabling CAC for the AC-VO queue does not enable CAC for the AC-VI
queue.
Examples
# Set AIFSN to 3 for the AC-VO queue.
<Sysname> system-view
[Sysname] interface WLAN-Radio2/0
[Sysname-WLAN-Radio2/0] wmm edca client ac-vo aifsn 3
wmm edca client (ac-be and ac-bk)
Use wmm edca client to set the EDCA parameters of the AC-VO or AC-VI queue for the clients in a BSS.
Use undo wmm edca client to restore the default.
Syntax
wmm edca client { ac-be | ac-bk } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax
ecwmax-value | txoplimit txoplimit-value } *
undo wmm edca client { ac-be | ac-bk } { aifsn | ecw | txoplimit | all }
Default
The following table lists the default EDCA parameter settings for the AC-BK and AC-BE queues for clients.
