The default is still to send on all interfaces. e.g. { "execute": "announce-self", "arguments": { "initial": 50, "max": 550, "= rounds": 5, "step": 50, "ifaces": ["vn2","vn1"] } } Note: There's still only one timer for the qmp command, so that performing an 'announce-self' on one list of interfaces followed by another 'announce-self' on another list will stop the announces on the existing set.
