Command Usage
◆ When proxy reporting is enabled with this command, reports received from
downstream hosts are summarized and used to build internal membership
states. Proxy-reporting devices may use the all-zeros IP source address when
forwarding any summarized reports upstream. For this reason, IGMP
membership reports received by the snooping switch must not be rejected
because the source IP address is set to 0.0.0.0.
