Command Mode

Interface Configuration (VLAN)

Command Usage

The IGMP snooping immediate-leave feature enables a Layer 2 LAN interface to be removed from the multicast forwarding table without first sending an IGMP group-specific query to the interface. Upon receiving a group-specific IGMPv2 leave message, the switch immediately removes the interface from the Layer 2 forwarding table entry for that multicast group, unless a multicast router was learned on the port.

Example

Console(config)#interface vlan 1

Console(config-if)#ip igmp snooping immediate-leave

Console(config-if)#

show ip igmp snooping

This command shows the IGMP snooping configuration.
