• The leave-proxy feature does not function when a switch is set as the querier.
Example
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
show ip igmp snooping
This command shows the IGMP snooping configuration.
Default Setting
None
Command Mode
Privileged Exec
