4 Command Line Interface

• The leave-proxy feature does not function when a switch is set as the querier.

Example

Console(config)#ip igmp snooping leave-proxy

Console(config)#

ip igmp snooping immediate-leave

This command enables IGMP immediate leave for specific VLAN. Use the no form to disable the feature for a VLAN.

Syntax

[no] ip igmp snooping immediate-leave

Default Setting

Disabled

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.

Default Setting

None

Command Mode

Privileged Exec
