Show additional edge device information in Araneo based on LLDP

Show additional edge device information in Araneo based on LLDP

Introduction

Starting from Araneo version 1.9.0, Araneo will show additional information of edge devices if the edge devices support LLDP (Link Layer Discovery Protocol).
If the LLDP information contains an IPv4 management address, it is possible to double click the edge device. Araneo will launch a webpage to this IP address. If the device is reachable from your computer and if it has a webpage available on this IP address, it will be shown.
It is also possible to edit the information of an edge device manually.

Fields

Vendors who would like to have this information visible in the Araneo software should support the following LLDP TLV's:
  1. MAC address: this field is derived from the LLDP Chassis Id TLV if the subtype is 'MAC address'. The chassis ID also allows to link multiple ports of the same unit (like primary/secondary) to the same device.
  2. Name: this field is derived from the LLDP System Name TLV
  3. Description: this field is derived from the LLDP System Description TLV
  4. Vendor: the vendor shown in Araneo is based on the MAC OUI, the first elements of the MAC address, which are registered by the device vendor. This information does not come from LLDP.
  5. IP address: this field is derived from the LLDP Management Address TLV 'Management Address' field.

Below is a figure explaining the link between the information in an LLDP packet from an edge device and what is shown in Araneo.
  1. On the left is a screenshot from a Wireshark capture of an LLDP packet transmitted by an edge device
  2. In the middle is a screenshot from the GigaCore API for LLDP neighbors on the port to which the edge device is connected: http://<GIGACORE_IP/api/lldp/neighbor/<PORT_NUMBER>
  3. On the right is a screenshot from Araneo to show how the LLDP information is visualized in the edge device
