active in spite of this setting.
•
IGMP SSM Range
SSM (Source-Specific Multicast) Range allows the SSM-aware hosts and routers
run the SSM service model for the groups in the address range.
•
Leave Proxy Enable
Enable IGMP Leave Proxy. This feature can be used to avoid forwarding
unnecessary leave messages to the router side.
•
Proxy Enable
Enable IGMP Proxy. This feature can be used to avoid forwarding unnecessary
join and leave messages to the router side.
•
Router Port
Specify which ports act as IGMP router ports. A router port is a port on the
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.
•
Fast Leave
Enable the fast leave on the port.
•
Throtting
Enable to limit the number of multicast groups to which a switch port can belong.
