Disabling IGMP Snooping on a VLAN

When IGMP snooping is enabled globally, you can still disable it for a specific VLAN. For example, the following commands cause IGMP snooping to be disabled for VLAN 20. This setting overrides the global setting.

device# configure terminal
device(config)# vlan 20
device(config-vlan-20)# multicast disable-igmp-snoop
