Igmp Host-Join Port - 3Com 8807 Command Reference Manual

IGMP Configuration Commands 609
Description
Use the igmp group-policy command to configure the filtering rule of multicast
groups on a specified VLAN so as to control the access to IP multicast groups. You
can configure only one ACL rule for each VLAN, and the new configured rule will
replace the old one.
Use the undo igmp group-policy command to cancel the configuration.
By default, no filtering rule is set in a VLAN. In this case, a host can join any
multicast group.
