3Com Switch 4500 Family - Multicast Static-Group Interface

2-16
Description
Use the igmp host-join command to configure the current port as a specified multicast group or source
and group member, namely configure the port as simulated member host for a specified multicast group
or source and group member.
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.
Related commands: igmp-snooping enable, multicast static-group interface, multicast
static-group vlan
z 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.

multicast group 225.0.0.1.
