No IGMP mappings are
configured by default.
If IGMPv3 is enabled on a VLAN interface of a switch that supports both IGMP Snooping and IGMP,
and if a port in that VLAN is configured as a simulated host, the simulated host will send IGMPv3 reports
even if you did not specify a multicast source when configuring simulated joining with the
igmp-snooping host-join
command. In this case, the corresponding multicast group will not be
created based on the configured IGMP SSM mappings. For details about the
igmp-snooping
host-join
command, refer to
IGMP Snooping Commands
