Traffic control
IGMP Forward All per port
U
This column of the table allows you to switch on/off the IGMP Snoo-
ping function "Forward All" when the global IGMP Snooping is swit-
ched on. With the "Forward All" setting, the Switch forwards all the
data packets with a Multicast address in the target address field to
this port.
Note: If a number of routers are connected to a subnetwork, then 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.
Static Query Port
U
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.
Learned Query Port
U
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.
GMRP per port
U
This table column enables you to switch on/off the GMRP for each
port when the global GMRP is switched on. When you switch off the
GMRP at a port, no registrations can be made for this port, and
GMRP packets cannot be sent out of this port.
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.
