(Optional) Configuring a Static Member Port

(Optional) Configuring a Static Member Port


Group member ports are connected to user hosts, and can be learned dynamically or configured manually. After MLD snooping is enabled in a VLAN, all interfaces in the VLAN learn multicast protocols packets by default. When an interface receives an MLD Report message, it becomes a dynamic member port. A dynamic member port has an aging timer.

If the user hosts connected to an interface need to receive multicast packets of a specific group or sent from a specific source to a specific group, add the interface to the group or source-group manually. The interface then becomes a static member port. Static member ports will never age.


  1. Run:


    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The interface view is displayed.

  3. (Optional) Run:

    undo mld-snooping learning vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }

    Dynamic learning of member ports is disabled.

    By default, dynamic learning of member ports is enabled. If this function is enabled, the interfaces that need to forward multicast data to hosts must be manually added to a multicast group.

  4. Run:

    mld-snooping static-group group-ipv6-address [ source source-ipv6-address ] vlan vlan-id

    The interface is manually added to a multicast group.
