2: System level
Parameters
service-template service-template-number: Specifies a service template by its number. The value range for the service-template-number argument is 1 to 1024.
percent percent: Specifies the percentage of the guaranteed bandwidth to the total bandwidth. The value range for the percent argument is 1 to 100.

client-rate-limit direction (WLAN service-based)
Use client-rate-limit direction to configure WLAN service-based client rate limiting.
Use undo client-rate-limit direction to restore the default.
Syntax
client-rate-limit direction { inbound | outbound } mode { dynamic | static } cir cir
undo client-rate-limit direction { inbound | outbound }
Default
WLAN service-based client rate limiting is disabled.
Views
Service template view
Default command level
2: System level
Parameters
inbound: Specifies the traffic from clients to APs (the outgoing traffic of clients).
outbound: Specifies the traffic from APs to clients (the incoming traffic of clients).
dynamic: Specifies the dynamic mode, where the rate limit for each client is the configured CIR/the number of online clients.
static: Specifies the static mode, where the rate limit for each client is the configured CIR.
cir cir: Specifies the rate limit (in kbps) for each client in static mode or specifies the total rate limit for all clients in dynamic mode. This argument ranges from 16 to 866700.
Usage guidelines
WLAN service-based client rate limiting can limit the rate of traffic from clients to APs or the rate of traffic from APs to clients. You can configure client rate limiting for both incoming traffic and outgoing traffic in the same service template.
Examples
# Configure WLAN service-based client rate limiting to limit the outgoing traffic rate of each client to 567 kbps and the total incoming traffic rate of all clients to 89 kbps.
<Sysname> system-view
[Sysname] wlan service-template 1 clear
[Sysname-wlan-st-1] client-rate-limit direction inbound mode static cir 567
[Sysname-wlan-st-1] client-rate-limit direction outbound mode dynamic cir 89

Default command 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.

ac-be: Specifies the AC-BE (best-effort traffic) queue.
ac-bk: Specifies the AC-BK (background traffic) queue.
all: Specifies all the EDCA parameters.

txoplimit-value: Specifies the 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: Specifies the ECWmin parameter of EDCA, which ranges from 0 to 15. The range of this argument is limited by the radio chip capability.
ecwmax-value: Specifies the ECWmax parameter of EDCA, which ranges from 0 to 15. The range of this argument is limited by the radio chip capability.
aifsn-value: Specifies the AIFSN parameter of EDCA, which ranges from 1 to 15. The range of this argument is limited by the radio chip capability.
Usage guidelines
For description on each EDCA parameter, see WLAN Configuration Guide.
ECWmin must be no greater than ECWmax. The two parameters must be enabled or disabled simultaneously.
When an AP uses 802.11b radio cards, H3C recommends that you set TXOPLimit values of the AC-BK, AC-BE, AC-VI, and AC-VO queues to 0, 0, 188, and 102, respectively.
Examples
# Set AIFSN to 2 for the AC-VO queue of the radio.
<Sysname> system-view
[Sysname] interface wlan-radio 1/0/1
[Sysname-WLAN-Radio1/0/1] wmm edca radio ac-vo aifsn 2
wmm edca client (ac-vo and ac-vi)
Use wmm edca client to set EDCA parameters for the AC-BE or AC-BK queue for clients.
Use undo wmm edca client to restore the default of the specified or all EDCA parameters for the specified AC queue.
Syntax
wmm edca client { ac-vo | ac-vi } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax ecwmax-value | txoplimit txoplimit-value | cac } *
undo wmm edca client { ac-vo | ac-vi } { aifsn | ecw | txoplimit | cac | all }

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: Specifies the AIFSN parameter of EDCA, which ranges from 2 to 15.
ecwmin-value: Specifies the ECWmin parameter of EDCA, which ranges from 0 to 15.
ecwmax-value: Specifies the ECWmax parameter of EDCA, which ranges from 0 to 15.
txoplimit-value: Specifies the 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, H3C 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, H3C recommends that you use the default TXOPLimit settings in Table 6.
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.
Examples
# Set AIFSN to 3 for the AC-VO queue.
<Sysname> system-view
[Sysname] interface wlan-radio 1/0/1
[Sysname-WLAN-Radio1/0/1] 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 }

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, H3C recommends that you set the TXOPLimit value to 0 for both the AC-BK and AC-BE queues.
If both 802.11b and 802.11g clients are present, H3C recommends that you use the default TXOPLimit settings for the AC-BK and AC-BE queues.
Examples
# Set AIFSN to 5 for the AC-BE queue.
<Sysname> system-view
[Sysname] interface wlan-radio 1/0/1
[Sysname-WLAN-Radio1/0/1] wmm edca client ac-be aifsn 5
wmm enable
Use wmm enable to enable the WMM function.
Use undo wmm enable to disable the WMM function.
Syntax

Usage guidelines
The 802.11n and 802.11ac protocols stipulate that all 802.11n and 802.11ac clients support WLAN QoS. Therefore, when the radio operates in 802.11an, 802.11gn, or 802.11ac mode, you must enable WMM. Otherwise, the associated 802.11n or 802.11ac clients may fail to communicate.
Examples
# Disable the WMM function.
<Sysname> system-view
[Sysname] interface wlan-radio 1/0/1
[Sysname-WLAN-Radio1/0/1] undo wmm enable
wmm svp map-ac
Use wmm svp map-ac to map SVP packets to a specific AC queue.
Use undo wmm svp map-ac to restore the default.
Syntax
wmm svp map-ac { ac-vo | ac-vi | ac-be | ac-bk }
undo wmm svp map-ac
Default
SVP packet mapping is disabled.
