Temporary PoE+ power drop

Symptom

Cause

If LLDP is disabled at runtime, and a PD is using PoE+ power that has been negotiated through LLDP, there is a temporary power drop; the port begins using PoE+ power through the PLC. This event is recorded in the Event Log.When LLDP is enabled again, it causes a temporary power drop. This event is also recorded in the Event Log.
