Network Map

LibreNMS shows a dynamic network map from the data of your devices. These menu options open the maps:

  • Overview -> Maps -> Network
  • Overview -> Maps -> Device Group Maps
  • The Neighbours -> Map tab when viewing a single device The Neighbours tab appears only for a device with xDP neighbours

A network map uses one of these sources:

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

By default, LibreNMS uses both sources. This configuration option enables and disables each source:

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

Remove mac or xdp from the list. xDP uses FDP, CDP, or LLDP, from the device type.

The global map can become large. A large map draws slowly and responds slowly. On a large network, use the network map of the device neighbour page. You can also build device groups and use the device group maps.

Settings

The Vis JS Options configure the map display.
