MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6 Stopping Multi-Source Replicas

The STOP SLAVE statement can be used to stop a multi-source replica. By default, if you use the STOP SLAVE statement on a multi-source replica all channels are stopped. Optionally, use the FOR CHANNEL channel clause to stop only a specific channel.

For the full syntax of the STOP SLAVE command and other available options, see Section, “STOP SLAVE Statement”.
