Information the LLDP Agent Advertises

The LLDP agent transmits system and connectivity information in LLDP packets or LLDPDUs. These packets contain information units that are individually formatted in Type-Length-Value (TLV) format. Thus, the information units are also called TLV units. Certain TLV units are mandatory and are included in LLDP packets by default when LLDP is enabled. You cannot use the lldpadm command to exclude any of these units. The mandatory TLV units are as follows:

The Chassis ID is the same information that is generated by the hostid command. The Port ID is the MAC address of the physical NIC. Multiple LLDP agents can be enabled on a single system depending on the number of links. The Chassis ID and Port ID combination uniquely identifies an agent and distinguishes it from other agents on the system.

Optional TLV units can be added to an LLDP packet. These optional TLV units are means for vendors to insert vendor-specific TLV units to be advertised. The TLV units are identified by individual organization unique identifiers (OUIs) and are typed according to whether these OUIs follow IEEE 802.1 specifications or IEEE 802.3 specifications. LLDP agent properties can be configured to enable or disable the transmission of these optional TLV units.

The following table lists each TLV type or group, its corresponding property name, as well as the TLV units for each property, and their descriptions. You configure any one of these properties to specify the TLV units to be included in the packets when LLDP is enabled.

Table 7-1 TLV Units That Can Be Enabled for an LLDP Agent

TLV Type
Property Name
TLV units
Basic management
sysname, portdesc, syscapab, sysdesc, mgmtaddr
Specifies the system name, port description, system capability, system description, and management address to be advertised.
802.1 OUI
vlanname, pvid, linkaggr, pfc, appln, evb, etscfg
Specifies the following to be advertised: VLAN name, port VLAN ID, link aggregation, TLV units for priority-based flow control, application, enhanced transmission selection, and edge virtual bridging.
802.3 OUI
Specifies the maximum frame size to be advertised.
Oracle-specific OUI (which is defined as 0x0003BA)
Specifies the VNIC to be advertised if a virtual network is configured.
