A. Link Aggregation Types: Feature Comparison
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:
Chassis ID
Port ID
TTL (time to live)
End of PDU
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.
