SNR S2940-8G-v2 Switch Configuration Guide
IPv4 Multicast Protocol
Priority Strategy Multicast.
The Multicast Packet Source Controllable technology of Security Controllable Multicast tech-
nology 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.
40.2.2 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 no-
ticeable that, after enabling source control globally, all mul-
ticast 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.
The next is to configure the rule of source control. It is configured in the same manner as for
ACL, and uses ACL number of 5000-5099, every rule number can be used to configure 10 rules. It
is noticeable that these rules are ordered, the front one is the one which is configured the earliest.
