Command Usage
◆ 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.
Example
Console(config)#ip igmp snooping proxy-reporting
Console(config)#
