Configure Link Layer Discovery Protocol
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.
LLDP is a one-way protocol without any request/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 disabled 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:
