The Multicast Packet Source Controllable technology of Security Controllable Multicast technology is mainly

processed in the following manners:

1． On the edge switch, if source under-control multicast is configured, then only multicast data from

specified group of specified source can pass.

2． For RP switch in the core of PIM-SM, for REGISTER information out of specified source and

specified group, REGISTER_STOP is transmitted directly and table entry is not allowed to set up.

(This task is implemented in PIM-SM model).

The implement of Multicast User Controllable technology of Security Controllable Multicast technology is

based on the control over IGMP report message sent out by the user, thus the model being controlled is

IGMP snooping and IGMP model, of which the control logic includes the following three, i.e. to take control

based on VLAN+MAC address transmitting packets, to take control based on IP address of transmitting

packets and to take control based on the port where messages enter, in which IGMP snooping can use the

above three methods to take control simultaneously, while since IGMP model is located at layer 3, it only

takes control over the IP address transmitting packets .

The Service-Oriented Priority Strategy Multicast of Security Controllable technology adopts the following

mode: for multicast data in limit range, set the priority specified by the user at the join-in end so that data can

be sent in a higher priority on TRUNK port, consequently guarantee the transmission is processed in

user-specified priority in the entire network.

48.8.2 DCSCM Configuration Task List

1. Source Control Configuration

2. Destination Control Configuration

3. Multicast Strategy Configuration

1． Source Control Configuration

Source Control Configuration has three parts, of which the first is to enable source control. The command of

source control is as follows:

Command

Explanation

Global Configuration Mode

[no] ip multicast source-control

(Required)

Enable source control globally, the “

no ip

multicast source-control

” command disables

source control globally. It is noticeable that, after

enabling source control globally, all multicast

packets are discarded by default. All source

control configuration can not be processed until

that it is enabled globally, while source control

can not be disabled until all configured rules are

disabled.
