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 (Usually 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.
16.5.5 ECSCM Troubleshooting
The effect of ECSCM module itself is similar to ACL, and the problems occurred are
usually related to improper configuration. Please read the descriptions above carefully. If
you still can determine the cause of the problem, please send your configurations and the
effects you expect to the after-sale service staff of our company.
