• VLAN ID—Defines the VLAN ID of the group to be added.
• IP Version—Select the IP address type.
• IP Multicast Group Address—Define the IP address of the new Multicast
group.
• Source Specific—Indicates that the entry contains a specific source, and

a (*,G) entry, an IP group address from any IP source.
• IP Source Address—Defines the source address to be included.
Click Apply. The IP Multicast group is added, and the device is updated.
To configure and display the registration of an IP group address, select an address
and click Details. The IP Multicast Interface Settings page opens.
The VLAN ID, IP Version, IP Multicast Group Address, and Source IP Address
selected are displayed as read-only in the top of the window. You can select the
filter type:
• Interface Type equals to—Select whether to display ports or LAGs.
For each interface, select its association type. The options are as follows:
• Static—Attaches the interface to the Multicast group as a static member.
• Forbidden—Specifies that this port is forbidden from joining this group on
this VLAN.
• None—Indicates that the port is not currently a member of this Multicast
group on this VLAN. This is selected by default until Static or Forbidden is
selected.
Click Apply. The Running Configuration file is updated.
To support selective Multicast forwarding (IPv4), Bridge Multicast filtering must be
enabled (in the Properties page), and IGMP Snooping must be enabled globally
and for each relevant VLAN (in the IGMP Snooping page).
