Hello,

Hi,
I don't think Ryu returns wrong dpid.
$ sudo ryu-manager ryu.app.simple_switch_13 ryu.app.ofctl_rest
loading app ryu.app.simple_switch_13
loading app ryu.app.ofctl_rest
loading app ryu.controller.ofp_handler
instantiating app None of DPSet
creating context dpset
creating context wsgi
instantiating app ryu.app.ofctl_rest of RestStatsApi
instantiating app ryu.app.simple_switch_13 of SimpleSwitch13

$ curl -X GET http://localhost:8080/stats/switches | python -mjson.tool

Maybe I think json parse tool(you use) has some problems.
In my enviroment, "jq" returned different dpid.
$ curl -X GET http://localhost:8080/stats/switches | jq .
[
6790944927334400000
]
But, I don't know why...
Refer to
https://github.com/stedolan/jq/issues/143
https://github.com/stedolan/jq/issues/178
It seems that some JSON parsers and JavaScript engines do not support 64-bit
integer and round the value down automatically.
Thanks
