To do...
3.
Enable WMM.
4.
Set the EDCA parameters of
AC-VO or AC-VI queues for
clients.
5.
Set the EDCA parameters of
AC-BE or AC-BK queues for
clients.
6.
Set the EDCA parameters and
specify the ACK policy for the
radio.
7.
Set the CAC policy.
8.
Map SVP packets to a
specified AC queue.
If CAC is enabled for an AC queue, CAC is also enabled for the 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.
HP recommends you use the default EDCA parameter settings for APs and clients (except the TXOPLimit
parameter for devices using 802.1 1b radio cards) unless it is necessary to modify the default settings.
When the radio card of a device is 802.1 1b, set the TXOPLimit values of the AC-BK, AC-BE, AC-VI, and
AC-VO queues to 0, 0, 188, and 102, respectively.
The SVP packet mapping function takes effect only after you enable WMM.
Use the command...
wmm enable
wmm edca client { ac-vo | ac-vi }
{ aifsn aifsn-value | ecw ecwmin
ecwmin-value ecwmax ecwmax
-value | txoplimit txoplimit-value |
cac } *
wmm edca client { ac-be | ac-bk }
{ aifsn aifsn-value | ecw ecwmin
ecwmin-value ecwmax ecwmax
-value | txoplimit txoplimit -value } *
wmm edca radio { ac-vo | ac-vi |
ac-be | ac-bk } { aifsn aifsn-value |
ecw ecwmin ecwmin-value ecwmax
ecwmax -value | txoplimit txoplimit
-value | noack } *
wmm cac policy { channelutilization
[ channelutilization-value ] | users
[ users-number ] }
wmm svp map-ac { ac-vi | ac-vo |
ac-be | ac-bk }

Remarks
Required.
Enabled by default.
The 802.11n protocol stipulates
that all 802.11n clients support
WLAN QoS. When the radio
works in 802.11gn mode, you
should enable WMM. Otherwise,
the associated 802.11n clients
may fail to communicate.
Optional.
By default, a client uses the default
EDCA parameters shown in
3.
Optional.
By default, a client uses the default
EDCA parameters shown in
3.
Optional.
By default, an AP uses the default
EDCA parameters shown in
4
and uses the Normal ACK
policy.
Optional.
By default, the users-based
admission policy applies, with the
maximum number of users being
20.
Optional.
By default, the SVP packet
mapping function is disabled.
SVP packet mapping applies to
non WMM clients, and does not
take effect on WMM clients.
