Disabling the Flooding of Unregistered IPv4 Multicast Frames in an IGMP-Snooping-Enabled VLAN

Unregistered IPv4 multicast frames can be disabled in an IGMP-snooping-enabled VLAN. The following task disables the flooding of unregistered IPv4 multicast frames in an IGMP-snooping-enabled VLAN.

Disabling the flooding of unregistered IPv4 multicast frames in an IGMP-snooping-enabled VLAN is supported on the following platforms:

  • RUCKUS ICX 7850 (standalone, stacking and SPX stack configuration)
  • RUCKUS ICX 7750 (standalone, stacking and SPX stack configuration)
  • RUCKUS ICX 7650 (standalone, stacking and SPX stack configuration)
  • RUCKUS ICX 7550 (standalone, stacking and SPX stack configuration)
  • RUCKUS ICX 7450 (standalone and stacking)
  • RUCKUS ICX 7250 (standalone and stacking)
  • RUCKUS ICX 7150 (standalone and stacking)

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

  1. Use the configure terminal command to enter global configuration mode. 
    device# configure terminal
  2. Use the ip multicast disable-flooding command to disable the flooding of unregistered IPv4 multicast frames. 
    device# ip multicast disable-flooding

The following example disables flooding of unregistered IPv4 multicast frames. 

device# configure terminal
device(config)# ip multicast disable-flooding
