I will go with D. {master:0}[edit protocols lldp] root@vQFXRE2# show interface all; interface xe-0/0/1 { power-negotiation; } LLDP and LLDP-MED also provide PoE power management capabilities. LLDP power negotiation allows the switch to manage PoE power by negotiating with LLDP-enabled powered devices to dynamically allocate PoE power as needed. LLDP power priority allows an LLDP-enabled powered device to set the PoE power priority on the switch interface to which it connects. https://www.juniper.net/documentation/us/en/software/junos/user-access/topics/topic-map/device-discovery-using-lldp-lldp-med.html#d146e357 https://www.juniper.net/documentation/us/en/software/junos/user-access/topics/topic-map/device-discovery-using-lldp-lldp-med.html#id-understanding-lldp-and-lldp-med-on-ex-series-switches.
