configure
Enter global configuration mode.
interface {fastEthernet port | range fastEthernet port-list | gigabitEthernet port | range
gigabitEthernet port-list | ten-gigabitEthernet port | range ten-gigabitEthernet port-list |
port-channel port-channel-id | range port-channel port-channel-list }
Enter interface configuration
ip igmp snooping
Enable IGMP Snooping for the port. By default, it is enabled.
ip igmp snooping immediate-leave
(Optional) Enable Fast Leave on the specified port.
Fast Leave can be enabled on a per-port basis or per-VLAN basis. When enabled on a per-port
basis, the switch will remove the port from the corresponding multicast group of all VLANs
before forwarding the leave message to the querier.
You should only use Fast Leave for a port when there is a single receiver connected to the
port. For more details about Fast Leave, see
show ip igmp snooping interface [fastEthernet [ port-list ] | gigabitEthernet [ port-list ] | ten-
gigabitEthernet [ port-list ] | port-channel [ port-channel-list ] ] basic-config
Show the basic IGMP Snooping configuration on the specified port(s) or of all the ports.
end
