Configuring WMM

Configuring WMM

Context

Adjust WMM parameter settings as follows:
  • Manual adjustment: You can manually adjust EDCA parameter settings and ACK policies for APs and STAs.
  • Automatic adjustment: After multimedia air interface optimization is enabled, the system automatically adjusts EDCA parameter settings and ACK policies for APs and STAs.

For details about the configuration for automatic adjustment, see Configuring Multimedia Air Interface Optimization.

Pre-configuration Tasks

Before configuring WMM, perform the task of WLAN Service Configuration.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run wlan

    The WLAN view is displayed.

  3. Run radio-2g-profile name profile-name or radio-5g-profile name profile-name

    The 2G or 5G radio profile view is displayed.

  4. Run undo wmm disable

    WMM is enabled.

    By default, WMM is enabled.

    NOTE:

    802.11n and 802.11ac STAs must support WMM. If the WMM function is disabled in a radio, 802.11n and 802.11ac cannot work and STAs can access the network only in 802.11a/b/g mode.

    If the WMM function is disabled, the access of non-HT STAs fails to be denied.

  5. (Optional) Run wmm mandatory enable

    STAs that do not support WMM are forbidden to connect to a WMM-enabled AP.

    By default, STAs that do not support WMM are allowed to connect to a WMM-enabled AP.

    On a WLAN, wireless channels are open and all STAs have an equal chance to occupy the wireless channels. You can configure WMM to assign different priorities to packets and enable high-priority packets to preferentially use wireless channel resources, meeting differentiated service requirements. You can also disable STAs that do not support WMM from connecting to a WMM-enabled AP, which prevents those STAs from preempting channels of WMM-capable STAs.

  6. Run wmm edca-ap { ac-vo | ac-vi | ac-be | ac-bk } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax ecwmax-value | txoplimit txoplimit-value | ack-policy { normal | noack } } *

    EDCA parameters and ACK policies are set for APs.

    Table 9-7 lists the default EDCA parameter settings and ACK policies for APs.
    Table 9-7  Default EDCA parameter settings and ACK policies for APs
    Packet Type ECWmax ECWmin AIFSN TXOPLimit ACK Policy
    AC_VO 3 2 1 47 normal
    AC_VI 4 3 1 94 normal
    AC_BE 6 4 3 0 normal
    AC_BK 10 4 7 0 normal

    As shown in the table, queues of AC_VO, AC_VI, AC_BE, and AC_BK are in descending order of priority.

    NOTE:
    After the high-density function is enabled on an AP, the AP will optimize EDCA parameters of AC_BE packets, for example, adjusting the contention window size. In this way, the probability of user collisions will be reduced, and users can enjoy better service experience in high-density scenarios. If you configure EDCA parameters in the WMM profile on the AP, the configuration does not take effect on AC_BE packets.

  7. Run quit

    Return to the WLAN view.

  8. Run ssid-profile name profile-name

    The SSID profile view is displayed.

  9. Run wmm edca-client { ac-vo | ac-vi | ac-be | ac-bk } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax ecwmax-value | txoplimit txoplimit-value } *

    EDCA parameters are set for STAs.

    Table 9-8 lists the default EDCA parameter settings for STAs.
    Table 9-8  Default EDCA parameter settings for STAs
    Packet Type ECWmax ECWmin AIFSN TXOPLimit
    AC_VO 3 2 2 47
    AC_VI 4 3 2 94
    AC_BE 10 4 3 0
    AC_BK 10 4 7 0

    As shown in the table, queues of AC_VO, AC_VI, AC_BE, and AC_BK are in descending order of priority.

Verifying the Configuration

  • Run the display radio-5g-profile name profile-name or display radio-2g-profile name profile-name command to check the WMM configuration in a radio profile.

  • Run the display ssid-profile name profile-name command to check the WMM configuration in an SSID profile.
