Network Map

LibreNMS has the ability to show you a network mab based on:

• xDP Discovery
• MAC addresses

By default, both are are included but you can enable / disable either one using the following config option:

$config['network_map_items'] = array('mac','xdp');

Either remove mac or xdp depending on which you want.

A global map will be drawn from the information in the database, it is worth noting that this could lead to a large network map. Network maps for individual devices are available showing the relationship with other devices.
