LLDP Emulation

The optional LLDP Emulation feature allows a PSA-3000 or PSL-3000 test port to behave just like an 802.3at or 802.3bt PD that uses LLDP to convey its power demands.  802.3 PoE LLDP is a special variant of LLDP protocol that involves handshakes and protocol timing between a PSE and a PD.
