BNM IEEE LLDP Info

The LLDP Object is an instance of Type LldpInformationType and represents the same structure as the YANG container lldp defined in the IEEE 802.1ABcu-2021. This object shall be read-only. The content is filled by the LLDP agent, based on the current configuration and operation. This LLDP agent behaves according to IEEE 802.1AB-2016 and is configured via mechanisms defined in IEEE 802.1AB-2016.

Note: The behaviour of an LLDP agent can be further specified and limited by profiles (either IEEE or OPC). This specification only represents data received and transmitted by this agent and is independent of the agent configuration.

Annex A.4 shows an example for the topology discovery using the information models of two neighbour OPC UA Servers.
