Overview of LLDP in Oracle Solaris

LLDP advertises information throughout a LAN for purposes of topology discovery. With this protocol, a system can advertise connectivity and management information to other systems on the network. This information can include system capabilities, management addresses, and other information relevant to network operations. This protocol also enables that same system to receive similar information about other systems that are on the same local network.

In Oracle Solaris, LLDP is also used to exchange data center bridging exchange protocol (DCBX) TLV units. DCBX provides configuration information about DCB features such as priority-based flow control (PFC) and enhanced transmission selection (ETS). For more information about DCB, see Chapter 8, Working With Data Center Bridging Features in Oracle Solaris.

With LLDP, the system administrator can easily detect faulty system configurations, particularly in complex networks that include virtual local area networks (VLANs), link aggregations, and so on. Information about the topology can be obtained readily without requiring to trace physical connections between servers, switches, and other devices that comprise the network.

Components of an LLDP Implementation

LLDP is implemented with the following components:

Information Sources of the LLDP Agent

The LLDP agent transmits as well as receives LLDP data units (LLDPDUs). The agent manages and stores the information contained in these LLDPDUs in two types of data stores:

LLDP Agent Modes of Operation

The LLDP agent operates in the following modes:

SMF Property for LLDP

The service management facility (SMFS) property auto-enable-agents controls how LLDP is enabled on the system. With this property, you can choose to enable LLDP globally across all the physical links or only one physical link at a time. The property can have one of three possible values:

Note that each time you customize the auto-enable-agents property, you must restart the LLDP SMF service for the new value to become effective.
