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.
Applications
PROFINET uses LLDP for topology diagnostics. In the default setting, LLDP is enabled for
ports p1 - P4; in other words, LLDP frames are sent and received on the ports.
The information sent is stored on every device with LLDP capability in an LLDP MIB file.
Network management systems can access these LLDP MIB files using SNMP and therefore
recreate the existing network topology. In this way, an administrator can find out which
network components are connected to each other and can localize disruptions.
On this page, you have the option of enabling or disabling sending and/or receiving per port.
