LLDP Emulation

The IEEE 802.3 specifications require that Type 2, Type 3, and Type 4 PDs implement PoE LLDP and use the Power via MDI TLV for power negotiation. This requirement  therefore applies to any PD that draws more than 13 watts.  The PDA-600 family includes an option to flexibly emulate any PSE while capturing and analyzing the LLDP power negotiation protocol from a PD.
