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.
Example
Console(config)#ip igmp snooping leave-proxy
Console(config)#
