Igmp-Snooping Host-Aging-Time - 3Com S7906E Command Reference Manual

Use the undo igmp-snooping group-policy command to remove a multicast group filter on the
current port(s).
By default, no multicast group filter is configured on an interface, namely a host can join any valid
multicast group.
Note that:
If you do not specify any VLAN when using this command in Ethernet interface view or Layer 2
aggregate interface view, the command will take effect for all VLANs the interface belongs to; if you
specify a VLAN or multiple VLANs, the command will take effect only if the interface belongs to the
specified VLAN(s).
If you do not specify any VLAN when using this command in port group view, the command will
take effect on all the ports in this group; if you specify a VLAN or multiple VLANs, the command will
take effect only on those ports in this group that belong to the specified VLAN(s).
If the specified ACL does not exist or the ACL rule is null, all multicast groups will be filtered out.
You can configure different ACL rules for a port in different VLANs; for a given VLAN, a newly
configured ACL rule will override the existing one.
