Link Layer Discovery Protocol (LLDP)
The IEEE 802.1AB defined standard, Link Layer Discovery Protocol (LLDP), allows stations residing on an IEEE
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; there are no 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/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.
LLDP Configuration
Use the LLDP Configuration page to specify global LLDP parameters and to configure the protocol on
individual ports.
To display the LLDP Configuration page, click LLDP > LLDP Configuration in the navigation pane.
