Viewing PoE Configuration and Status

Displaying the Switch's Global PoE Power Status

Syntax: show power-management

Displays the switch's global PoE power status, including:

• Max Power: Lists the maximum PoE wattage available to

provision active PoE ports on the switch.

• Power In Use: Lists the amount of PoE power presently in use.

• 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%)

For example, in the default PoE configuration, when the switch is running

with several ports supporting PD loads, show power-management displays data

similar to the following on a Switch 2626-PWR device:
