Default Setting
IGMP Version 2
Command Mode
Global Configuration
Command Usage
• All systems on the subnet must support the same version. If there are legacy
devices in your network that only support Version 1, you will also have to
configure this switch to use Version 1.
• Some commands are only enabled for IGMPv2 and/or v3, including ip igmp
snooping querier, ip igmp snooping query-max-response-time, ip igmp
snooping query-interval, and ip igmp snooping immediate leave.
Example
The following configures the switch to use IGMP Version 1:
Console(config)#ip igmp snooping version 1
Console(config)#

ip igmp snooping leave-proxy

This command enables IGMP leave proxy on the switch. Use the no form to disable
the feature.
Syntax
[no] ip igmp snooping leave-proxy
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
• The IGMP snooping leave-proxy feature suppresses all unnecessary IGMP
leave messages so that the non-querier switch forwards an IGMP leave
packet only when the last dynamic member port leaves a multicast group.
• The leave-proxy feature does not function when a switch is set as the querier.
