Step 3 Select the multicast protocol.
Run the igmp mode { proxy | snooping } command to select the L2 multicast protocol. By
default, the multicast function is disabled in the system.
In IGMP snooping mode, proxy can be enabled for the report packet and leave packet. When a
multicast user joins or leaves a multicast program, the MA5616 can implement IGMP proxy.
IGMP snooping and IGMP proxy are controlled separately.
l Run the igmp report-proxy enable command to enable the proxy of the snooping report
l Run the igmp leave-proxy enable command to enable the proxy of the snooping leave

Dynamic generation mode: A program is generated according to the request of the user. In
this mode, the program list is not required; however, the functions such as program
management, user multicast bandwidth management, program preview, and program
prejoin are not supported.
Run the igmp match mode disable command to configure the dynamic generation mode.
CAUTION
When you run the igmp match mode { enable | disable } command to switch the program
matching mode:
l This command can be executed only when the IGMP mode is disabled.
l The system will delete all the programs in this multicast VLAN. In this case, if a user
is online, the system will force the user to go offline.
Run the igmp match group command to configure the IP address range of the program
group that can be dynamically generated in the multicast VLAN. After the configuration,
the user can request for only the programs whose IP addresses are within the specified
range.
In multicast VLAN mode, run the igmp uplink-port command to configure the multicast
uplink port. After the configuration, all the packets from the multicast VLAN are forwarded
or received through this uplink port.
In BTV mode, run the igmp uplink-port-mode command to change the mode of the
multicast uplink port. By default, the multicast uplink port is in default mode. On the MSTP
network, the multicast uplink port adopts the MSTP mode.
l Default mode: If a multicast VLAN contains only one uplink port, the IGMP packets
that go upstream can be sent only through this port. If a multicast VLAN contains
multiple uplink ports, the IGMP packets that go upstream are sent through all the uplink
ports.
l MSTP mode: This mode is applicable to the MSTP network.
packet. When the first user requests for a program, after authenticating the user, the
MA5616 sends the user report packet to the network side and obtains a corresponding
multicast stream from the multicast router. The MA5616 does not send the report packets
from the subsequent users for joining the same program to the network side any more.
packet. When the last user requests for leaving a program, the MA5616 sends the user leave
packet to the network side and notifies the upper-layer device of stopping sending multicast
