The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations 
on an 802 LAN to advertise major capabilities and physical descriptions. This information is 
viewed by a network manager to identify system topology and detect bad configurations on 
the LAN.

From the LLDP configuration menu, you can access the following links:

LLDP is a one-way protocol; there are no request and response sequences. Information is 
advertised by stations implementing the transmit function, and is received and processed by 
stations implementing the receive function. The transmit and receive functions can be 
enabled or disabled separately per port. By default, both transmit and receive are enabled on 
all ports. The application is responsible for starting each transmit and receive state machine 
appropriately, based on the configured status and operational state of the port.

The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an 
enhancement to LLDP with the following features:

Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority, and DiffServ settings), 
enabling plug and play networking.

Device location discovery for creation of location databases.

Extended and automated power management of Power over Ethernet endpoints.

Inventory management, enabling network administrators to track their network devices 
and determine their characteristics (manufacturer, software and hardware versions, serial 
or asset number).
