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 system-view

    The system view is displayed.

  2. Run wlan

    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 quit

    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.

Verifying the Configuration

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