Switch(config)#ip multicast destination-control
Switch(config)#ip multicast destination-control 10.0.0.0/8 access-group 6000
In this way, users of this network segment can only join groups other than 238.0.0.0/8.
3. Multicast
strategy
Server 210.1.1.1 is distributing important multicast data on group 239.1.2.3, we can
configure on its join-in switch as follows:
Switch(config)#ip multicast policy 210.1.1.1/32 239.1.2.3/32 cos 4
In this way, the multicast stream will have a priority of value 4 (Uausally this is pretty
higher, the higher possible one is protocol data; if higher priority is set, when there is too
many multicast data, it might cause abnormal behavior of the switch protocol) when it
gets to other switches through this switch.

effects you expect to the after-sale service staff of our company.
