Use the no form of this command to disable IGMP Snooping function. ip igmp snooping no ip igmp snooping Syntax None Default IGMP snooping is disabled on all VLAN interfaces Command Mode The IGMP snooping global state is disabled by default. The global function control is not stored in NVRAM. VLAN interface configuration or Global configuration Usage Guideline Under interface configuration for an interface, the corresponding VLAN must first be created. When the user executes the command under global configuration, it will enable/ disable all existing VLAN IGMP snooping function. However the command takes effect only in the running configuration and it will not be kept in NVRAM for the next start up configuration. For a VLAN interface, the command can be kept in NVRAM for the next startup system configuration mode. To disable IGMP snooping on a VLAN interface, use the no ip igmp snooping under VLAN interface configuration mode. The command will, under global configuration mode, enable IGMP snooping functions for all existing VLANs. Similarly, no ip igmp snooping will disable IGMP snooping function for all of the existing VLANs. As a VLAN is deleted, the related IGMP snooping setting for the VLAN is also removed from system configuration. CLI Reference Guide 262
