DefaultMethod in Route file not working

Hi, The default method in the routes file setting does not seem to be working. Can someone please help?

* --------------------------------------------------------------------
* Router Setup

*/
$routes->setDefaultNamespace('App\Controllers');
$routes->setDefaultController('Console');
$routes->setDefaultMethod('portfunc');
$routes->setTranslateURIDashes(false);
$routes->set404Override();
$routes->setAutoRoute(true);


<?php

namespace App\Controllers;

class Console extends BaseController
{
    public function index()
    {
        echo "Console";
    }
    public function portfunc() {
        echo "Console port";
    }
}

Correct me if I'm wrong, I think, the controller should point to the default function set as portfunc().
Kindly intervene. Thanks

<?php

namespace App\Controllers;

class Console extends BaseController
{
    public function index()
    {
        echo "Console";
    }
    public function portfunc() {
        echo "Console port";
    }
}




   public function index()
    {
        echo "Console";
