configuration.

Multicast Strategy Configuration

Multicast Strategy uses the manner of specifying priority for specified multicast data to achieve

and guarantee the effects the specific user requires. It is noticeable that multicast data can not

get a special care all along unless the data are transmitted at TRUNK port. The configuration is

very simple, it has only one command, i.e. to set priority for the specified multicast. The

commands are as follows:

Command

Explanation

Global Configuration Mode

[no] ip multicast policy <IPADDRESS/M>

<IPADDRESS/M> cos <priority>

Configure multicast strategy, specify

priority for sources and groups in

specific range, and the range is <0-7>.

34.2.3 DCSCM Configuration Examples

Source Control

In order to prevent an Edge Switch from putting out multicast data ad asbitsium, we configure

Edge Switch so that only the switch at port Ethernet1/5 is allowed to transmit multicast, and

the data group must be 225.1.2.3. Also, switch connected up to port Ethernet1/10 can transmit

multicast data without any limit, and we can make the following configuration.

EC(config)#access-list 5000 permit ip any host 225.1.2.3

EC(config)#access-list 5001 permit ip any any

EC(config)#ip multicast source-control

EC(config)#interface ethernet1/5

EC(Config-If-Ethernet1/5)#ip multicast source-control access-group 5000

EC(config)#interface ethernet1/10

EC(Config-If-Ethernet1/10)#ip multicast source-control access-group 5001

Destination Control

We want to limit users with address in 10.0.0.0/8 network segment from entering the group of

238.0.0.0/8, so we can make the following configuration:

Firstly enable IGMP snooping in the VLAN it is located (Here it is assumed to be in VLAN2)

EC(config)#ip igmp snooping

EC(config)#ip igmp snooping vlan 2

After that, configure relative destination control access-list, and configure specified IP

address to use that access-list.

Switch(config)#access-list 6000 deny ip any 238.0.0.0 0.255.255.255
