When the radio card of a device is 802.11b, H3C recommends that you 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.

Configuration procedure

Step Command

Remarks

219.

Enter system view.

system-view

N/A

220.

Enter WLAN-radio interface
view.

interface wlan-radio radio-number N/A

221.

Enable WMM.

wmm enable

By default, WMM is enabled.
The 802.11n protocol stipulates
that all 802.11n clients support

WLAN QoS. Therefore, when the

radio operates in 802.11gn
mode, you should enable WMM.

Otherwise, the associated

802.11n clients might fail to

communicate.

222.

Set the EDCA parameters of
AC-VO or AC-VI queues for

clients.

wmm edca client { ac-vo | ac-vi }
{ aifsn aifsn-value | ecw ecwmin
ecwmin-value ecwmax ecwmax

-value | txoplimit txoplimit-value |

cac } *

Optional.
By default, a client uses the default
EDCA parameters shown in

Table

3

.

223.

Set the EDCA parameters of
AC-BE or AC-BK queues for

clients.

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

ecwmin-value ecwmax ecwmax

-value | txoplimit txoplimit -value } *

Optional.
By default, a client uses the default

EDCA parameters shown in

Table

3

.

224.

Set the EDCA parameters and
specify the ACK policy for the

radio.

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 } *

Optional.
By default, an AP uses the default
EDCA parameters shown in

Table

4

and uses the Normal ACK

policy.

225.

Set the CAC policy.

wmm cac policy { channelutilization
[ channelutilization-value ] | users

[ users-number ] }

Optional.
By default, the users-based

admission policy applies, with the

maximum number of users being
20.

226.

Map SVP packets to a

specified AC queue.

wmm svp map-ac { ac-vi | ac-vo |
ac-be | ac-bk }

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.
