Ethernet switch that leads towards the Layer 3 multicast device or IGMP querier.
The Switch forwards IGMP join or leave packets to an IGMP router port.

Auto:
Select "Auto" to have the Industrial Managed Switch automatically
uses the port as IGMP Router port if the port receives IGMP query
packets.

Fix:
The Industrial Managed Switch always uses the specified port as
an IGMP Router port. Use this mode when you connect an IGMP
multicast server or IP camera which applied with multicast protocol to
the port.

None:
The Industrial Managed Switch will not use the specified port as an
IGMP Router port. The Industrial Managed Switch will not keep any
record of an IGMP router being connected to this port. Use this mode
when you connect other IGMP multicast servers directly on the non-
querier Industrial Managed Switch and don't want the multicast
stream to be flooded by uplinking switch through the port that is
connected to the IGMP querier.
Enable the fast leave on the port.
Enable to limit the number of multicast groups to which a switch port can belong.
