Response -

But when in implemented network client function after making uri as -
v2.0/ports.json?device_id=d61674ce-ef3e-4371-a227-1e841944686a

request is successful but in body I can't see any port. i.e. body is empty while there is one port connected to router as shown above using curl.

My client function is as -

    def list_router_port(self, uuid):
        print uuid
        uri = '%s/ports?device_id=%s' % (self.uri_prefix, uuid)
        print uri
        resp, body = self.get(uri, self.headers)
        print resp
        print body
        body = json.loads(body)
        return resp, body
