IGMP Snooping Configuration Guide
Proxy reporting is enabled by default in Supermicro switches. Users can disable or enable the proxy
reporting feature by following the steps below.
Step Command
Step 1 configure terminal
Step 2 ip igmp snooping proxy-reporting
Step 3 end

Step 4
Step 5 write startup-config
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.

SMIS(config)# ip igmp snooping proxy-reporting
SMIS(config)# end
1.13 Sending Queries when Topology Changes
When spanning tree topology changes, multicast traffic is often flooded. To quickly recover from the
flood, 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.
