Figure7- 31. Setup IEEE 802.1Q Multicast Forwarding Screen
Use the Multicast Forwarding Screen to define the following parameters:
MAC Address
The MAC address of the static source of multicast packets.
VID
The VLAN ID of the VLAN the above MAC address belongs to.
PortMap / State
Allows the selection of ports that will be members of the static multicast
group and ports that are either forbidden from joining dynamically, or that
can join the multicast group dynamically, using GMRP. The options are;
None – no restrictions on the port dynamically joining the multicast group,
Egress – the port is a static member of the multicast group, and Forbidden –
the port is restricted from joining the multicast group dynamically. For
example, if None is chosen, then an end station attached to the port can join
the multicast group using GMRP.
IGMP Snooping
When enabled for IGMP snooping, the Switch can open or close a port to a specific Multicast group member
based on IGMP messages sent from the device to the IGMP host or vice versa.
