Disabling the flooding of unregistered IPv4 multicast frames in an IGMP-snooping-enabled VLAN

NOTE
Disabling the flooding of unregistered IPv4 multicast frames in an IGMP-snooping-enabled VLAN is supported on the following platforms:
  • The Brocade ICX 7750 (standalone and stacking)
  • The Brocade ICX 7450 (standalone and stacking)
  • The Brocade ICX 7250 (standalone and stacking)
  • The Ruckus ICX 7150 (standalone and stacking)

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

To disable the flooding of unregistered IPv4 multicast frames in an IGMP-snooping-enabled VLAN, use the ip multicast disable-flooding command in global configuration mode.

The following example disables flooding of unregistered IPv4 multicast frames. 

device(config)# ip multicast disable-flooding
