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.

    <port-list>

    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.
