H3C Technologies H3C MSR 50 - Manual (Page 75)

• 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.
