# Start or Pause synchronization

Pause or start synchronization by using the `start` and `stop` subcommands. If synchronization is stopped and then restarted, changes made at the Sync Source while synchronization was stopped will still be detected and applied. Synchronization for individual Sync Pipes can be started or stopped using the `--pipe-name` option. If the `--pipe-name` option is omitted, then synchronization is started or stopped globally.

The following command stops all Sync Pipes:

```shell
$ bin/realtime-sync stop --port 389 \
  --bindDN "uid=admin,dc=example,dc=com" \
  --bindPassword secret \
  --no-prompt
```

If a topology has two Sync Pipes, Sync Pipe1 and Sync Pipe2, the following command stops Sync Pipe1.

```shell
$ bin/realtime-sync stop --pipe-name "Sync Pipe1" \
  --port 389 \
  --bindDN "uid=admin,dc=example,dc=com" \
  --bindPassword secret --no-prompt
```
