Usage Guidelines

The no form of this command enables the flooding of unregistered IPv4 multicast frames in an IGMP-snooping-enabled VLAN.

Support for this command on RUCKUS ICX 7750 devices was introduced in FastIron 8.0.10d. In releases prior to FastIron 8.0.30, support for this command on the RUCKUS ICX 7750 was for devices in standalone mode only.

Support for this command on the RUCKUS ICX 7450 and RUCKUS ICX 7250 was introduced in FastIron 8.0.30.

After the hardware forwarding database (FDB) entry is made, the multicast traffic is switched only to the VLAN hosts that are members of the multicast group. This can avoid congestion and loss of traffic on the ports that have not subscribed to this IPv4 multicast traffic.

Examples

The following example disables flooding of unregistered IPv4 multicast frames. 

device(config)# ip multicast disable-flooding
