H3C S7500E Series Command Reference Manual page 120

rule: Specifies the access right of users connected to the specified UNI port to the specified multicast
channel, which can be deny, permit, or preview time-slice.
deny: Denies users access to the specified multicast channels.
permit: Grants users access to the specified multicast channels.
channel-number: Number of channels that can be accessed at the same time when the permit
keyword is used, in the range 1 to 5.
preview time-slice: Grants users preview right to multicast channels with specified lengths.
preview-time: Allowed preview time, in minutes. It is in the range 1 to 3.
interval-time: Allowed preview interval., in minutes. It is in the range 1 to 10.
preview-times: Allowed preview times, in the range 1 to 3.
reset-interval-time: Preview reset interval, namely, time elapsed (in minutes) after the preset number of
preview times is reached and before the next preview can be performed. It is in the range 1 to 43200.
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 of the current ONU.
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
Operation in the IP Multicast Volume.
When using the uni multicast-control command to configure users' preview right to multicast channel
services, if you assign preview right to multiple multicast channels for users connected to a UNI, only
one of these specified multicast channels is allowed to be accessed at any given point in time.
