Multicast Filtering Commands
This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts that want to
receive a specific multicast service. It identifies the ports containing hosts requesting a service and sends data
out to those ports only. It then propagates the service request up to any neighboring multicast switch/router to
ensure that it will continue to receive the multicast service.

Command Usage: All systems on the subnet must support the same

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-time and ip igmp query-timeout.
Example: The following configures the switch to use IGMP Version 1:
Console(config)#ip igmp snooping version 1
Console(config)#
