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
Displays the switch's global PoE power status, including:
• Pre-standard Detect
Shows whether PoE for pre-802.3af-standard powered devices is enabled on the switch. (Default: Off; shows
On when PoE for pre-802.3af-standard powered devices has been enabled.)
• Operational Status
Indicates whether PoE power is available on the switch. (Default: On; shows Off if PoE power is not available.
Shows Faulty if internal or external PoE power is oversubscribed or faulty.)
• Usage Threshold (%)
Lists the configured percentage of available PoE power provisioning the switch must exceed to generate a
usage notice in the form of an Event Log message and an SNMP trap. If this event is followed by a drop in
power provisioning below the threshold, the switch generates another SNMP trap and Event Log message.
Event Log messages are also sent to any optionally configured debug destinations. (Default: 80%)
• 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.
brief Displays PoE information for each port. See Viewing PoE status on all ports on page 99.

Displays PoE information for the ports in port-list. See Viewing the PoE status on specific
ports on page 101.
The show power-over-ethernet displays data similar to that shown in Output for the show power-over-
ethernet command on page 99.
