You can use Joi.number().integer() in the validate section:

server.route({
    method: 'GET',
    path:'/users/{limit?}',
    config: {
        validate: {
            params: {
                limit: Joi.number().integer()
            }
        }
    },
    handler: function (request, reply) {
        reply('ok');
    }
});
