The default value is 125 seconds.
Exits the configuration mode.
show ip igmp snooping vlan<vlan>
Displays the IGMP snooping

SMIS(config-vlan)# ip igmp snooping query-interval 300
SMIS(config-vlan)# end
7.7 Report Forward
When IGMP snooping is enabled, Supermicro switches forward IGMP host member reports to IGMP
routers. When a switch has not recognized any router ports, it forwards IGMP host member reports to all
ports except the port on which the host member report was received. When a switch recognizes a router
port, it forwards the IGMP host member reports to only the recognized router port.
The switch behavior can be changed to forward the IGMP host member reports to all the ports except the
port on which the host member report was received irrespective of router port learning.
Follow the steps below to configure a switch to forward the IGMP host member reports to all the ports
except the port on which the host member report was received.
