The Multicast page is displayed with the IGMP tab selected by default,
as shown in Figure 72.

3. Configure the following parameters as necessary.
Enable IGMP Snooping Status
Enables and disables IGMP snooping on the switch. A check in the
box indicates that IGMP snooping is enabled.
Multicast Host Topology
Defines whether there is only one host node per switch port or multiple
host nodes per port. Possible settings are Edge (Single-Host/Port) and
Intermediate (Multi-Host/Port).
The Single-Host/Port (Edge) setting is appropriate when there is only
one host node connected to each port on the switch. This setting
causes the switch to immediately stop sending multicast packets out a
switch port when a host node signals its desire to leave a multicast
group by sending a leave request or when the host node stops sending
reports and times out. The switch forwards the leave request to the
router and simultaneously ceases transmission of any further multicast
packets out the port where the host node is connected.
