The EcoNAT system supports Link Layer Discovery Protocol (LLDP) and sends packets to its active ports at 30-s intervals, advertising its presence and capabilities to neighbor nodes. This can be disabled by setting the lldp parameter to off in the system.nat_defaults branch. Also, the value of the lldp_hostname parameter can be changed in the system.nat_defaults branch. This value is inserted in the System Name (TLV Type 5) field of an LLDP frame.
Additionally, the neighbor nodes that use LLDP protocol can be viewed. To do this, run the show neighbours <interface name> command for a specific interface, or show neighbours all for all interfaces.
