Description
Use the
uni multicast-control multicast-address
command to configure the access (permit, preview,
or deny) to multicast channels for the users connected to the specified UNI.
Use the
undo
uni multicast-control multicast-address
command to remove the configuration.
Note that this command is available in multicast control mode only.
If this command is executed with the
source-ip
keyword, the OLT will process the received IGMPv3
packets as follows:
For IS_IN, TO_IN, or ALLOW IGMPv3 packets, if the multicast IP address and source IP address
carried in the packets are within the range configured for the multicast rights, the OLT creates the
multicast table entries; otherwise, the OLT discards the packets.
If the packet type is IS_EX or TO_EX, the OLT discards the packets.
If the packet type is BLOCK, the OLT directly deletes the corresponding multicast table entries
without checking the packet rights.
For details about IS_IN, TO_IN, ALLOW, IS_EX, TO_EX, and BLOCK IGMPv3 packets, see
IGMP
