ip igmp snooping version

This command configures the IGMP snooping version. Use the no form to restore the default.

ip igmp snooping version {1 2} no ip igmp snooping version

1 - IGMP Version 1

2 - IGMP Version 2

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, including ip igmp query-max-response-timeand ip igmp query-timeout.

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.
