After the switches learn which ports are requesting access to the IP Multicast
stream, all other ports not responding to the queries are blocked from receiving the
IP Multicast (see Figure 1-28
).

The consolidated proxy report generated by the switch remains transparent to
layer 3 of the International Organization for Standardization, Open Systems
Interconnection (ISO/OSI) model. (The switch IP address and MAC address are
not part of proxy report generation.) The last reporting IGMP group member in
each VLAN represents all of the hosts in that VLAN and IGMP group.
