Configuring Multicast-to-Unicast Conversion

Configuring Multicast-to-Unicast Conversion


You can enable the function of converting multicast packets to unicast packets in scenarios that have high requirements on multicast stream transmission, such as a high-definition video on-demand scenario.

After the function is enabled, an AP listens on Report and Leave packets to maintain multicast-to-unicast entries. When sending multicast packets to the client, the AP converts the multicast packets to unicast packets based on the multicast-to-unicast entries to improve multicast stream transmission efficiency.

After adaptive multicast-to-unicast conversion is enabled, when the air interface performance becomes a bottleneck during multicast-to-unicast conversion, an AP automatically switches the multicast group containing the minimum number of STAs to the multicast mode. After the air interface performance is improved and keeps being improved for a period of time, the AP automatically switches the multicast group containing the maximum number of STAs to the unicast mode. In this way, the air interface performance is automatically adjusted without manual intervention, improving wireless user experience.

Pre-configuration Tasks

Before configuring multicast-to-unicast conversion, complete the following tasks:


  1. Run:


    The system view is displayed.

  2. Run:


    The WLAN view is displayed.

  3. Run:

    traffic-profile name profile-name

    A traffic profile is created, and the traffic profile view is displayed.

    By default, the system provides the traffic profile default.

  4. Run:

    traffic-optimize multicast-unicast enable

    Multicast-to-unicast conversion is enabled in the traffic profile.

    By default, the function of converting multicast packets to unicast packets is disabled in a traffic profile.

  5. (Optional) Run:

    undo traffic-optimize multicast-unicast dynamic-adaptive disable

    Adaptive multicast-to-unicast conversion is enabled.

    By default, adaptive multicast-to-unicast conversion is enabled in a traffic profile.

  6. Run:


    Return to the WLAN view.

  7. Run:

    vap-profile name profile-name

    The VAP profile view is displayed.

  8. Run:

    traffic-profile profile-name

    The traffic profile is bound to the VAP profile.

    By default, the traffic profile default is bound to a VAP profile.

  9. Run:


    Return to the WLAN view.

  10. Run:

    commit { all | ap-name ap-name | ap-id { ap-id1 [ to ap-id2 ] } &<1-10> }

    Configurations are delivered to APs.

Verifying the Configuration

  • Run the display traffic-profile { all | name profile-name } command to check the multicast-to-unicast configuration in a traffic profile.
