RabbitMQ max-hops where to declare this?

I am trying to figure out how to set the max-hops against a federated policy that I want to make, but the documentation doesn’t say where to put this within the command.

www.rabbitmq.com/federated-exchanges.html

Is it just like this, note I have put max-hops at the end:

rabbitmqctl set_policy ha-fed "^MyExchange" '{"federation-upstream-set":"all", "ha-sync-mode":"automatic"' --priority 10 --apply-to exchanges --max-hops 1

or does the max-hops go inside the JSON block?

The documentation doesn’t help by saying max-hops=1 which is neither a JSON colon declaration or a command line one with the space?

Any help would be greatly appreciated, many thanks
