flood enable|disable
Configures the switch to flood unregistered IP multicast reports to all ports. The default setting is
enabled.
Note: If IGMP hosts reside on different VLANs, you must disable IGMP flooding to ensure that
multicast data is forwarded across the VLANs.
cpu enable|disable
Configures the switch to forward unregistered IP multicast traffic to the MP, which adds an entry in
the IPMC table, as follows:
 If no Mrouter is present, drop subsequent packets with same IPMC.
 If an Mrouter is present, forward subsequent packets to the Mrouter(s) on the ingress VLAN.
The default setting is enabled.
