4.7 Configuring LLDP Settings

Link Layer Discovery Protocol (LLDP) is a Layer 2 protocol (IEEE standard 802.1AB) used to determine
the capabilities of devices such as repeaters, bridges, access points, routers and wireless clients.
LLDP enables devices to advertise their capabilities and media-specific configurations. LLDP provides
a method of discovering and representing the physical network connections of a given network
management domain. The LLDP neighbor discovery protocol allows you to discover and maintain
accurate network topologies in a multi-vendor environment.
The information is in a Type Length Value (TLV) format for each data item. TLV information is
transmitted in a LLDP protocol data unit (LLDPDU), enclosed in an Ethernet frame and sent to a
destination MAC address. Certain TLVs are mandatory, and always sent once LLDP is enabled, while
other TLVs are optionally configured. LLDP defines a set of common advertisement messages, a
protocol for transmitting the advertisements and a method for storing information in received
advertisements. A switch can receive and record the TLVs, but not transmit them. The information
distributed using LLDP is stored by its recipients in a standard MIB, making it possible for the
information to be accessed by a NMS using a management protocol such as SNMP.
LLDP transmits periodic advertisements containing device information and media-specific
configuration information to neighbors attached to the same network. LLDP agents cannot solicit
information from other agents by using LLDP.
