the startup configuration.
The “no ip igmp snooping proxy-reporting” command disables the proxy reporting feature.
The example below shows the commands used to enable the proxy reporting feature.
Enable IGMP snooping proxy reporting.

SMIS(config)# ip igmp snooping proxy-reporting
SMIS(config)# end
7.11 Sending Queries WhenTopology Changes
When spanning tree topology changes, multicast traffic is often flooded. To quickly recover from flooding,
switches can be configured to send general IGMP queries to all ports when spanning tree topology
changes. This helps switches correctly recognize member ports based on the new spanning tree topology.
Supermicro switches do not send general IGMP queries by default when spanning tree topology changes.
Users can enable the switch to send general IGMP queries when spanning tree topology change events
occur. When enabled in RSTP mode, switches send general IGMP queries to all ports except for router
ports. In MSTP mode, switches send general IGMP queries to all ports except for the router ports of the
VLANs associated with topology changed MST instance.
Follow the steps below to enable the switch to send general IGMP queries when spanning tree topology
changes.
Step
Command
Description
Step 1
configure terminal
Enters the configuration mode.
Step 2
ip igmp snooping send-query enable
Enables the switch to send general
IGMP queries when spanning tree
topology changes.
Step 3
end
Exits the configuration mode.
Step 4
show ip igmp snooping globals
Displays the IGMP snooping
information.
Step 5
write startup-config
Optional step – saves this IGMP
snooping configuration to be part of
the startup configuration.
The “ip igmp snooping send-query disable” command configuresthe switch to not send
