Network Map

LibreNMS has the ability to show you a dynamic network map based on data collected from devices. These maps are accessed through the following menu options:

  • Overview -> Maps -> Network
  • Overview -> Maps -> Device Group Maps
  • The Neighbours -> Map tab when viewing a single device (the Neighbours tab will only show if a device has xDP neighbours)

These network maps can be based on:

  • xDP Discovery
  • MAC addresses (ARP entries matching interface IP and MAC)

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

lnms config:set network_map_items '["mac","xdp"]'

Either remove mac or xdp depending on which you want. XDP is based on FDP, CDP and LLDP support based on the device type.

The map display can be configured by altering the
