power inline policeChapter 2<strong>Catalyst</strong> <strong>3750</strong>-E <strong>and</strong> <strong>3560</strong>-E <strong>Switch</strong> <strong>Cisco</strong> <strong>IOS</strong> Comm<strong>and</strong>s3. The switch automatically sets the power usage of the device by using CDP power negotiation or bythe IEEE classification <strong>and</strong> LLPD power negotiation.Use the first or second method in the previous list to manually configure the cutoff-power value byentering the power inline consumption default wattage global configuration comm<strong>and</strong>, the powerinline consumption wattage interface configuration comm<strong>and</strong>, or the power inline [auto | static max]max-wattage comm<strong>and</strong>.NoteIf you do not manually configure the cutoff-power value, the switch automatically determines the valueby using CDP power negotiation. If the switch cannot determine the value by using one of these methods,it uses the default value of 15.4 W. For more information about the cutoff power value, the powerconsumption values that the switch uses, <strong>and</strong> the actual power consumption value of the connecteddevice, see the “Power Monitoring <strong>and</strong> Power Policing” section in the “Configuring InterfaceCharacteristics” chapter of the software configuration guide for this release.If power policing is enabled, the switch polices power usage by comparing the real-time powerconsumption to the maximum power allocated on the PoE port. If the device uses more than themaximum power allocation (or cutoff power) on the port, the switch either turns power off to the port,or the switch generates a syslog message <strong>and</strong> updates the LEDs (the port LEDs are blinking amber) whilestill providing power to the device.• To configure the switch to turn off power to the port <strong>and</strong> put the port in the error-disabled state, usethe power inline police interface configuration comm<strong>and</strong>.• To configure the switch to generate a syslog message while still providing power to the device, usethe power inline police action log comm<strong>and</strong>.If you do not enter the action log keywords, the default action is to shut down the port, turn offpower to it, <strong>and</strong> put the port in the PoE error-disabled state. To configure the PoE port toautomatically recover from the error-disabled state, use the errdisable detect cause inline-powerglobal configuration comm<strong>and</strong> to enable error-disabled detection for the PoE cause <strong>and</strong> theerrdisable recovery cause inline-power interval interval global configuration comm<strong>and</strong> to enablethe recovery timer for the PoE error-disabled cause.CautionIf policing is disabled, no action occurs when the powered device consumes more than the maximumpower allocation on the port, which could adversely affect the switch.ExamplesThis example shows how to enable policing of the power consumption <strong>and</strong> configuring the switch togenerate a syslog message on the PoE port on a switch:<strong>Switch</strong>(config)# interface gigabitethernet1/0/2<strong>Switch</strong>(config-if)# power inline police action logYou can verify your settings by entering the show power inline police privileged EXEC comm<strong>and</strong>.Related Comm<strong>and</strong>s Comm<strong>and</strong> Descriptionerrdisable detect Enables error-disabled detection for the PoE cause.cause inline-powererrdisable recoverycause inline-powerConfigures the PoE recovery mechanism variables.2-442<strong>Catalyst</strong> <strong>3750</strong>-E <strong>and</strong> <strong>3560</strong>-E <strong>Switch</strong> Comm<strong>and</strong> ReferenceOL-9776-08
