Operating note
The advertisement of power with TLVs for LLDP PoE+ is enabled by default. If LLDP is disabled at runtime and a
PD is using PoE+ power that has been negotiated through LLDP, there will be a temporary power drop. The port
will begin 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)
Viewing the global PoE power status of the switch
Syntax:
show power-over-ethernet [brief | [[ethernet] <port-list>] | [slot <slot-id-range> | all>]]
Displays the switch's global PoE power status, including:
• Total Available Power
Lists the maximum PoE wattage available to provision active PoE ports on the switch. This is the amount of
usable power for PDs.
• Total Failover Power
Lists the amount of PoE power available in the event of a single power supply failure. This is the amount of
power the switch can maintain without dropping any PDs.
• Total Redundancy Power
Indicates the amount of PoE power held in reserve for redundancy in case of a power supply failure.
• Total Remaining Power
The amount of PoE power still available.
