LLDP
Identifying the network topology
LLDP (Link Layer Discovery Protocol) is defined in the IEEE 802.AB standard.
LLDP is a method used to discover the network topology. Network components exchange
information with their neighbor devices using LLDP.
Network components that support LLDP have an LLDP agent. The LLDP agent sends
information about itself and receives information from connected devices at periodic
intervals. The received information is stored in the MIB.
PROFINET uses LLDP for topology diagnostics. In the default setting, LLDP is enabled for
all ports; in other words, LLDP frames are sent and received on all ports. With this function,
you have the option of enabling or disabling sending and/or receiving per port.
