NOTE:
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. An Example: message would look like the following:
W 08/04/13 13:35:50 02768 ports: Port A1 PoE power dropped.
Exceeded physical classification for a PoE Type1 device (LLDP process
disabled)
When LLDP is enabled again, it causes a temporary power drop. This event is also recorded in the
Event Log. An Example: message looks like the following:
W 08/04/13 13:36:31 02771 ports: Port A1 PoE power dropped.
Exceeded physical classification due to change in classification type (LLDP
process enabled)
