Chapter 11 Configuring Interface Characteristics

Configuring Ethernet Interfaces

Caution You should carefully plan your switch power budget, enable the power monitoring feature, and make certain not to oversubscribe the power supply.

Note When you manually configure the power budget, you must also consider the power loss over the cable between the switch and the powered device.

When you enter the power inline consumption default wattage or the no power inline consumption default command, this caution message appears:

%CAUTION: Interface Gi1/0/1: Misconfiguring the 'power inline consumption/allocation' command may cause damage to the switch and void your warranty. Take precaution not to oversubscribe the power supply.

It is recommended to enable power policing if the switch supports it. Refer to documentation.

For more information about the IEEE power classifications, see the “Power over Ethernet Ports” section on page 11-6.

Beginning in privileged EXEC mode, follow these steps to configure the amount of power budgeted to a powered device connected to each PoE port on a switch:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	no cdp run	(Optional) Disable CDP.
Step 3
	power inline consumption default	Configure the power consumption of powered devices connected to each
	wattage	the PoE port on the switch. The range for each device is 4000 to
		15400 mW. The default is 15400 mW.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	show power inline consumption	Display the power consumption status.
	default
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To return to the default setting, use the no power inline consumption default global configuration command.

Beginning in privileged EXEC mode, follow these steps to configure amount of power budgeted to a powered device connected to a specific PoE port:

	Command		Purpose
Step 1	configure terminal		Enter global configuration mode.
Step 2	no cdp run		(Optional) Disable CDP.
Step 3	interface interface-id		Specify the physical port to be configured, and enter interface
			configuration mode.
Step 4	power inline consumption default		Configure the power consumption of a powered device connected to a
	wattage		PoE port on the switch. The range for each device is 4000 to 15400 mW.
			The default is 15400 mW.
