ip igmp snooping
Use this command to enable IGMP Snooping. When this command is used in the Global
Configuration mode, IGMP Snooping is enabled at the switch level. When this command is
used in Interface Configuration mode, IGMP Snooping is enabled for the specified VLANs.
Use the no variant of this command to either globally disable IGMP Snooping, or disable
IGMP Snooping on a specified interface.
Syntax
ip igmp snooping
no ip igmp snooping
Default
By default, IGMP Snooping is enabled both globally and on all VLANs.
Mode
Global Configuration and Interface Configuration for a VLAN interface.
Usage
For IGMP snooping to operate on particular VLAN interfaces, it must be enabled both
globally by using this command in Global Configuration mode, and on individual VLAN
interfaces by using this command in Interface Configuration mode (both are enabled by
default.)
Both IGMP snooping and MLD snooping must be enabled globally on the switch for IGMP
snooping to operate. MLD snooping is also enabled by default. To enable it if it has been
disabled, use the
ipv6 mld snooping command on page 32.22
in Global Configuration
mode.
Ensure your VLAN is configured first: see
Examples

Note
IGMP snooping cannot be disabled on an interface if IGMP snooping has
already been disabled globally. IGMP snooping can be disabled on both an
interface and globally if disabled on the interface first and then disabled
globally.
