ACLs configured on the inbound port. If allowed, the switch then adds the port to the
forward port list of the multicast group; otherwise, it drops the IGMP report packet and
no data flow then will be sent to this port. Thus the switch can control users’ multicast
program ordering.
User-defined ACL rule is a multicast address or multicast address range (224.0.0.1 to
239.255.255.255)
z If the rule is set as permit, the port can be added to the groups contained in the
permitted ACL range, but not to the groups outside the permitted ACL range.
z If the rule is set as deny and no other ACL is set as permit, the port cannot be
added to the groups within the denied ACL range, nor to the groups outside the
denied ACL range.
Note:
z Each VLAN of each port can only be configured with one ACL rule.
z If no ACL rule is configured or the configured port doesn’t belong to the specified
VLAN, the filtering configured by this command will not take effect.
z Most devices just broadcast unknown multicast packets, s o to prevent the case
where multicast data flow is sent as unknown multicast packets to the filtered ports,
this function is generally configured in combination with the unknown multicast
dropping function.
For the related command, see unknown-multicast drop enable.
Example
# Configure ACL 2000 to permit the accessing to multicast group
225.0.0.0~225.255.255.255.
z Configure ACL
[Quidway] acl number 2000
[Quidway-acl-basic-2000] rule permit source 225.0.0.0 0.255.255.255
z Create VLAN 2, and add Ethernet 0/1 to it.
[Quidway] vlan 2
[Quidway-vlan2] port Ethernet 0/1
z Set the filtering of IGMP Snooping Report packets applied to ACL 2000 of VLAN 2
on Ethernet 0/1.
[Quidway] interface Ethernet 0/1
[Quidway-Ethernet0/1] igmp-snooping group-policy 2000 vlan 2
# Configure ACL 2001 to deny the accessing to multicast group
225.0.0.0~225.255.255.255 and permit the accessing outside the range.
