Network Load Control
Settings per Port (Table)
"IGMP on"
This table column enables you to enable/disable the IGMP for each
port when the global IGMP Snooping is enabled. Disabling the IGMP
at a port prevents registration for this port.
"IGMP Forward All"
This table column enables you to enable/disable the "Forward All"
IGMP Snooping function when the global IGMP Snooping is
enabled. With the "Forward All" setting, the device sends to this port
all data packets with a Multicast address in the destination address
field.
Note: If a number of routers are connected to a subnetwork, you
must use IGMP version 1 so that all the routers receive all the
IGMP reports.
Note: If you use IGMP version 1 in a subnetwork, then you must also
use IGMP version 1 in the entire network.
"IGMP Automatic Query Port"
This table column shows you which ports the device has learned as
query ports, if "automatic" is selected in "Static Query Port".
"Static Query Port"
The device sends IGMP report messages to the ports at which it
receives IGMP queries (disable=default setting).
This column allows you to also send IGMP report messages to:
other selected ports (enable) or connected
Hirschmann devices (automatic).
"Learned Query Port"
This table column shows you at which ports the device has received
IGMP queries, if "disable" is selected in "Static Query Port".
