Description
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. Selections are as follows:
Auto
–
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 connecting an IGMP multicast server
or IP camera with multicast protocol to the port.
None
–
The industrial managed switch will not use the specified port as an
IGMP router port and will not keep any record of an IGMP router being
connected to this port. Use this mode when connecting other IGMP multicast
servers directly to the non-querier industrial managed switch, and you don’t
want the multicast stream to be flooded to the uplink switch through the port
that 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.
All
means all ports wil have one specific setting.

IGMP snooping VLAN configuration
The IGMP Snooping VLAN Configuration page shows up to 99 entries from the VLAN
table (default is 20 entries per page). The range of entries per page can be typed into
the
Start from VLAN
and
entries per page
fields. When initially accessing the page, it
shows the first 20 entries from the beginning of the VLAN table. The first entry shown
will be the one with the lowest VLAN ID found in the VLAN table.
