The database is accessible by a Network Management Station (NMS) using a management protocol
such as the Simple Network Management Protocol (SNMP).
Network connectivity device - A forwarding 802 LAN device, such as a router, switch, or wireless
access point.
Station - A node in a network.
TLV (Type-Length-Value) - An information element in an LLDPDU that describes the type of information
being sent, the length of the information string, and the value (actual information) that will be
transmitted.
TTL (Time-to-Live) - Specifies the length of time that the receiving device should maintain the
information acquired through LLDP in its MIB.
LLDP overview
LLDP enables a station attached to an IEEE 802 LAN/MAN to advertise its capabilities to, and to
discover, other stations in the same 802 LAN segments.
The information distributed by LLDP (the advertisement) is stored by the receiving device in a standard
Management Information Base (MIB), accessible by a Network Management System (NMS) using a
management protocol such as the Simple Network Management Protocol (SNMP). The information also
can be viewed from the CLI, using show LLDP commands.
The following diagram illustrates LLDP connectivity
