If an empty filter or empty filter set is assigned to a profile Enet connection, no IGMP Report received
from the respective server port is snooped.
•
If a filter rule is deleted from a multicast filter in use by a profile connection, it can take several seconds
(up to the idle timeout setting) for the server port to be removed from the IGMP group table.
With only IGMP Snooping enabled:
•
Multicast traffic for registered groups is forwarded to all member ports.
•
Unregistered multicast traffic is flooded to all VC ports.
•
Multicast traffic targeted to link-local addresses (224.0.0.0 – 224.0.0.255) is flooded to all VC ports
in the configured network.
•
Any other L2 multicast traffic is forwarded to all VC ports in the network.
With the "No Flood" feature enabled (IGMP snooping must be enabled to use this feature):
•
Multicast traffic for registered groups is forwarded to all member ports.
•
Unregistered multicast traffic from server downlink ports is forwarded to the active uplink port
configured for the corresponding Ethernet network.
•
Multicast traffic targeted to link-local addresses (224.0.0.0 – 224.0.0.255) is flooded to all VC ports
in the configured network.
•
Any other L2 multicast traffic is forwarded to all VC ports in the network.
With multicast filters configured for profile connections (IGMP Snooping must be enabled to use multicast
filters):
•
Multicast traffic for registered groups is forwarded to all member ports.
•
Unregistered multicast traffic is flooded to all VC ports on the configured VLAN by default. To prevent
flooding of unregistered multicast traffic, enable the “No Flood feature”.
•
Multicast traffic targeted to link-local addresses (224.0.0.0 – 224.0.0.255) is flooded to all VC ports
in the configured network.
•
Any other L2 multicast traffic is forwarded to all VC ports in the network.
With IGMP Snooping disabled, multicast traffic is flooded to all VC ports.
Modifying a multicast filter or filter set that is in use by one or more profile connections impacts all profile
connections.
