Commands to Configure IGMP Snooping

ip igmp snooping

The ip igmp snooping command, in Global Configuration mode, enables IGMP snooping on
all existing VLAN interfaces. The no form of this command disables IGMP snooping on all
existing VLAN interfaces.
By default, IGMP snooping is globally disabled on the switch. When enabled or disabled
globally, it is also enabled or disabled in all existing VLAN interfaces. IGMP snooping is by
default enabled on all VLANs, but can be enabled or disabled on a per-VLAN basis. After
you configure a VLAN interface for multicast routing, no configuration is needed for the
switch to access external multicast routers dynamically by using IGMP snooping.
When you enable IGMP snooping, the switch automatically learns the interfaces to which
multicast routers are connected. When you disable IGMP snooping, the entire configuration is
erased.
Global IGMP snooping overrides VLAN IGMP snooping. If global snooping is disabled, you
cannot enable VLAN snooping. If global snooping is enabled, you can enable or disable
VLAN snooping.
Command Syntax
device-name(config)#ip igmp snooping

ip igmp snooping vlan

The ip igmp snooping vlan command, in Global Configuration mode, enables IGMP
snooping on the specified VLAN. By default, IGMP snooping is enabled on all the VLANs.
