LLDP configuration
The main function of
Link Layer Discovery Protocol (LLDP)
is the exchange of information about
status and specifications between network devices. Information that LLDP gathers is stored on devices
and can be requested by the master computer via SNMP. Thus, the master computer can model the
network topology based on this information.
The switches support transmission of both standard and optional parameters, such as:
device name and description;
port name and description;
MAC/PHY information;
etc.
