Parameters
service-template service-template-number: Specifies a service template by its number.
percent percent: Specifies the percentage of the guaranteed bandwidth to the total bandwidth.
all: Specifies all service templates.
Description
Use bandwidth-guarantee service-template to configure a guaranteed bandwidth percent for the specified BSS.

Views
Service template view
Default level
2: System level
Parameters
inbound: Specifies the direction from client to AP.
outbound: Specifies the direction from AP to client.
dynamic: Specifies the dynamic mode, where the rate limit of a client is the configured total rate/the number of online clients.
static: Specifies the static mode, where the rate limit of a client is the configured value.

undo wmm cac policy
View
Radio-policy view
Default level
2: System level
Parameters
channelutilization: Uses the channel utilization-based admission policy for CAC.
channelutilization-value: Maximum channel utilization rate, which specifies the medium time of the accepted AC-VO traffic and AC-VI traffic to the valid time during the unit time. This argument ranges from 0 to 100. It is 65 by default. The unit is % (percentage). The valid time refers to the time available for transmitting and receiving data.
users: Uses the users-based admission policy for CAC.
users-number: Maximum number of clients allowed to be connected, which ranges from 0 to 64. This argument is 20 by default. A client is counted only once, even if it is using both the AC-VO and AC-VI queues.
Description
Use wmm cac policy to configure the access control policy for CAC.
Use undo wmm cac policy to restore the default.
By default, the users-based admission policy applies, with the maximum number of admitted users being 20.
Related commands: wmm edca client.
Examples
# Configure CAC to use the channel utilization-based admission policy, with the channel utilization rate being 70%.

all: Specifies all the EDCA parameters.
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.

Description
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.

NOTE: · For more information about 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, 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, use the default TXOPLimit settings in Table 7. · If CAC 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. |

NOTE: The 802.11n protocol stipulates that all 802.11n clients support WLAN QoS. Therefore, when the radio operates in 802.11an or 802.11gn mode, you should enable WMM. Otherwise, the associated 802.11n clients may fail to communicate. |
Examples
# Disable the WMM function.
<Sysname> system-view
[Sysname] wlan radio-policy radio1
[Sysname-wlan-rp-radio1] undo wmm enable
wmm svp map-ac
