After a group is deleted, if other IGMP membership report messages occur, the
interfaces can join the corresponding group again.

5.2.11 Configuring the Filtering Rule of Multicast Groups

On the IGMP snooping-enabled switch, you can configure ACL rules whether the
specified multicast group can be joined to a VLAN or not. This feature filters every
received IGMP join packet. According to the destination group address of the packets
and the ACL rule bound to the VLAN, the switch determines whether to discard the
packets or let them pass.
By setting the filtering rule of multicast groups in the VLAN, you can control access to IP
multicast groups. You can only configure one ACL rule for each VLAN, and the new
configured rule will replace the old one.
Perform the following configuration in VLAN view.
Table 5-11 Configure the aging time of multicast group members
Set the filtering rule of multicast groups
in the specified VLAN
Cancel the filtering rule of multicast
groups in the specified VLAN
By default, no filtering rule is set for a VLAN. In this case, a host can be joined to any
multicast group.
Caution:
If an inexistent acl-number is bound to the VLAN, or if the bound acl-number is not
configured with a rule, a host is still allowed to join any multicast group.
If no acl-number exists, you can also configure the filtering rule of multicast groups
in VLAN view. That is, this rule is not restricted by the ACL itself, and is valid for all
members in the specified VLAN.
