IEEE 802.3at “PoE Plus”
IEEE 802.3at to provide higher power PoE, with management
Many management needs aligned with LLDP-MED “Extended Power via MDI” TLV (aka Extended PoE TLV)
High synergy, since wired Ethernet IP Phones and other VoIP endpoints are a large category of devices, almost all using PoE
LLDP-MED Extended PoE TLV accepted as basis for PoE management
3 proposals at March IEEE 802.3 plenary, all use LLDP-MED data content (unclear which accepted … meeting was just last week)
