wmm cac policy
Syntax
wmm cac policy { channelutilization [ channelutilization-value ] | users [ users-number ] }
undo wmm cac policy
View
WLAN-radio interface view
Default Level
2: System level
Parameters
channelutilization: Uses the channel utilization-based admission policy for CAC.
channelutilization-value: Maximum channel utilization in percentage, 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 is in the range of 0 to 100. It is 65 by default. 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 AC-VO and AC-VI.
Description
Use the wmm cac policy command to configure the access control policy used for CAC.
Use the undo wmm cac policy command 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%.

Description
Use the wmm edca client command to set the EDCA parameters of AC-VO or AC-VI for the clients in a BSS.
Use the undo wmm edca client command to restore the default.

l For description on each EDCA parameter, see WLAN QoS in the WLAN Configuration Guide.
l ECWmin must not be greater than ECWmax. The two parameters must be enabled or disabled simultaneously.
l When all the clients are 802.11b terminals, it is recommended that you set the TXOPLimit to 188 and 108 for AC-VI and AC-VO respectively.
l If both 802.11b and 802.11g clients are present, it is recommended that you use the default TXOPLimit settings in Table 1-4.
l IF CAC is enabled for an AC, CAC is also enabled for ACs with higher priority. For example, if you use the wmm edca client command to enable CAC for AC-VI, CAC is also enabled for AC-VO. However, enabling CAC for AC-VO does not enable CAC for AC-VI.

l ECWmin must not be greater than ECWmax. The two parameters must be enabled or disabled simultaneously.
l When all the clients are 802.11b terminals, it is recommended that you set the TXOPLimit value to 0 for both AC-BK and AC-BE.

View
WLAN-radio interface view
Default Level
2: System level
Parameters
None
Description
Use the wmm enable command to enable the WMM function.
Use the undo wmm enable command to disable the WMM function.
The WMM function is enabled by default.
The 802.11n protocol stipulates that all 802.11n clients support WLAN QoS. Therefore, when the radio works 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.

Parameters
ac-vo: Specifies the AC-VO (voice traffic) queue.
ac-vi: Specifies the AC-VI (video traffic) queue.
ac-be: Specifies the AC-BE (best-effort traffic) queue.
ac-bk: Specifies the AC-BK (background traffic) queue.
Description
Use the wmm svp map-ac command to map SVP packets to a specific AC.
