Level: 8 In the global configuration mode, you can enable or disable the IGMP Snooping global state, and in the interface configuration mode, you can enable or disable the IGMP Snooping interface state.

DXS-3600-32S#configure terminal DXS-3600-32S(config)#ip igmp snooping DXS-3600-32S(config)# Example This example shows how to disable the IGMP Snooping state on interface VLAN 1. DXS-3600-32S#configure terminal DXS-3600-32S(config)#vlan 1 DXS-3600-32S(config-vlan)#no ip igmp snooping DXS-3600-32S(config-vlan)# 24-2 ip igmp snooping fast-leave This command is used to enable IGMP Snooping fast leave function. Use the no form of this command to disable this function. ip igmp snooping fast-leave no ip igmp snooping fast-leave Parameters Default Command Mode Command Default Level Usage Guideline None. By default, this option is disabled. Interface Configuration Mode. Level: 8 IGMP Snooping fast-leave processing allows removing a member interface from the membership entry without sending out IGMP group-specific queries, so that make the leaving more quickly. Upon receiving a group-specific IGMPv2 leave message or IGMPv3 TO_INCLUDE(NULL), if the host is the last member of group on the interface, IGMP Snooping immediately removes the interface from the membership table entry for that multicast group. To verify your configuration, use show ip igmp snooping. 266
