Viewing the global PoE power status of the switch


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.

    Displays PoE information for each port. See Viewing PoE status on all ports.


    Displays PoE information for the ports in port-list. See Viewing the PoE status on specific ports.

The show power-over-ethernet displays data similar to that shown in Output for the show power-over-ethernet command.
