U Static Query Port
A Switch sends IGMP report messages to the ports at which it
receives IGMP queries. This column allows you to also send IGMP
report messages to other selected ports.
U Learned Query Port
A Switch sends IGMP report messages to the ports at which it
receives IGMP queries. This column displays the ports on which the
Switch has received IGMP queries.
U GMRP Service Requirements per port
The "GMRP service requirements" of the GMRP standard describe
the GMRP service requirements of the terminal device on the entire
network.
D With the "selective" setting (GMRP default setting: forward all un-
registered groups) the switch sends to this port all data packets
with a multicast address in the target address field,
– which is entered in the filter table for this port
or
– for which no entry exists in the filter table.
D With the "all" setting (GMRP default setting: forward all groups)
the switch sends to this port all data packets with a multicast
address in the target address field.
Note: If the Switch is connected to a HIPER-Ring, in the case of a ring
interruption you can ensure quick reconfiguration of the network for data
packets with registered multicast target addresses by:
D switching on the IGMP at the ring ports and globally, and
D switching on the “IGMP Forward All” per port on the ring ports.
