The LLDP agent transmits and receives LLDP data units (LLDPDUs). The agent manages and stores information that is contained in these LLDPDUs in the following types of data stores:
Local management information base (MIB) – This data store contains network information that pertains to a system's specific link on which the LLDP agent is enabled. A local MIB contains both common and unique information. For example, the chassis ID is common information that is shared among all the LLDP agents on the system. However, port IDs for the system's datalinks are different. Therefore, each agent manages its own local MIB.
Remote MIB – Information in this data store is received from LLDP agents of peer hosts.
