Virtual Connect networks 117
• 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.
