(Optional) Configuring a Static Member Port

(Optional) Configuring a Static Member Port

Context

A member port is on a Layer 2 device and connects to receiver hosts which are multicast group members. The member port can be configured manually or learned dynamically by multicast protocols. When IGMP snooping is enabled in a VLAN, all interfaces in this VLAN learn forwarding entries from multicast packets. When an interface receives IGMP Report messages, the Layer 2 device sets this interface as a dynamic member port. A dynamic member port has an aging time.

If the hosts connected to an interface need to receive the multicast data sent to a specific multicast group or sent from a source to a group for a long time, add the interface statically to the group or source-group. The manually added interface is a static member port. Static member ports will not age out.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The interface view is displayed.

  3. (Optional) Run:

    undo igmp-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. To forward multicast data, the interfaces must be statically added to a multicast group after disabling dynamic learning of member ports.

  4. Run:

    l2-multicast static-group [ source-address source-ip-address ] group-address group-ip-address vlan { vlan-id1 [ to vlan-id2 ] } &<1-10>

    The interface is manually added to a multicast group and becomes a static member port.

    Or run:

    l2-multicast static-group [ source-address source-ip-address ] group-address group-ip-address1 to group-ip-address2 vlan vlan-id

    The interface is added to multiple multicast groups.
