LABEL DESCRIPTION
IGMP Snooping
Enable IGMP
Snooping
Select this option to enable IGMP Snooping to forward group multicast traffic only to ports that
are members of that group.
Unknown
Multicast Drop
Select this option to discard the frame when the Switch receives an unknown multicast frame.
Otherwise, the Switch sends the frame to all ports.
IGMP Static
Router Port
The Switch treats an IGMP query port as being connected to an IGMP multicast router (or
server). The Switch forwards IGMP join or leave packets to an IGMP query port.
Select a port to be used as an IGMP query port.
Or, select Auto to allow any port to be used as an IGMP router port after receiving an IGMP
query.
Note: If link aggregation is enabled, the ports in a link aggregation group will not be
available in this field.
Apply Click Apply to save your changes to the Switch.
