3. Change the following settings as needed:
Status— Enable or disable IGMP Snooping. When you enable
IGMP, the switch begins to build its multicast tables as queries
from the multicast router and reports from the host nodes arrive on
its ports. When you disable IGMP, the switch floods the multicast
packets on all of the ports except the port that received the packet.
Host Topology— Specify the IGMP host topology. Choose
between “Single” and “Multiple.” Select “Single” when the switch
has one-host-node per port. Select “Multiple” when the switch has
more than one host-node per port. By default, the switch is set to
“Single.”
Host/Router Timeout— Specify the host/router time in seconds
that the switch times out when it finds inactive host nodes and
multicast routers. The range is from 0 to 86,400 seconds (24
hours). The default is 260 seconds. Setting the timeout to zero (0)
disables the timer.
