By default numerous interface types and interface descriptions are excluded from this graph. The excluded defailts are:
```php
$config['device_traffic_iftype'][] = '/loopback/';
$config['device_traffic_iftype'][] = '/tunnel/';
$config['device_traffic_iftype'][] = '/virtual/';
$config['device_traffic_iftype'][] = '/mpls/';
$config['device_traffic_iftype'][] = '/ieee8023adLag/';
$config['device_traffic_iftype'][] = '/l2vlan/';
$config['device_traffic_iftype'][] = '/ppp/';
$config['device_traffic_descr'][] = '/loopback/';
$config['device_traffic_descr'][] = '/vlan/';
$config['device_traffic_descr'][] = '/tunnel/';
$config['device_traffic_descr'][] = '/bond/';
$config['device_traffic_descr'][] = '/null/';
$config['device_traffic_descr'][] = '/dummy/';
```
If you would like to re-include l2vlan interfaces for instance, you first need to `unset` the config array and set your options:
```php
unset($config['device_traffic_iftype']);
$config['device_traffic_iftype'][] = '/loopback/';
$config['device_traffic_iftype'][] = '/tunnel/';
$config['device_traffic_iftype'][] = '/virtual/';
$config['device_traffic_iftype'][] = '/mpls/';
$config['device_traffic_iftype'][] = '/ieee8023adLag/';
$config['device_traffic_iftype'][] = '/ppp/';
```
