When proxy reporting is enabled with this command, the switch
•
performs "IGMP Snooping with Proxy Reporting" (as defined in DSL
Forum TR-101, April 2006), including last leave, and query
suppression. Last leave sends out a proxy query when the last member
leaves a multicast group, and query suppression means that specific
queries are not forwarded from an upstream multicast router to hosts
downstream from this device.
If the IGMP proxy reporting is configured on a VLAN, this setting takes
•
precedence over the global configuration.
E
XAMPLE
Console(config)#ip igmp snooping proxy-reporting
Console(config)#
This command enables the switch as an IGMP querier. Use the no form to
disable it.
