Use the undo igmp host-join command to remove the current port as a simulated member host for the
specified multicast group or source-group.
Unlike a static member port, a port configured as a simulated member host will age out like a dynamic
member port.

Before configuring a port as a simulated host, enable IGMP Snooping in VLAN view first.
z
The current port must belong to the specified VLAN; otherwise this configuration does not take
effect.
Examples
# Configure Ethernet 1/0/1 in VLAN 1 as a simulated member host for multicast source 1.1.1.1 and
multicast group 225.0.0.1.
