Configuring PoE

Budgeting Power for Devices Connected to a PoE Port

grants a power request, the switch adjusts the power budget according to the powered-device IEEE classification. If the powered device is a class 0 (class status unknown) or a class 3, the switch budgets 15,400 mW for the device, regardless of the CDP-specific amount of power needed. If the powered device reports a higher class than its CDP-specific consumption or does not support power classification (defaults to class 0), the switch can power fewer devices because it uses the IEEE class information to track the global power budget.

By using the power inline consumption wattage interface configuration command or the power inline consumption default wattage global configuration command, you can override the default power requirement specified by the IEEE classification. The difference between what is mandated by the IEEE classification and what is actually needed by the device is reclaimed into the global power budget for use by additional devices. You can then extend the switch power budget and use it more effectively.

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.

Budgeting Power to All PoE ports

Perform this task to configure the amount of power budgeted to a powered device connected to each PoE port on a switch:

SUMMARY STEPS

1.configure terminal

2.no cdp run

3.power inline consumption default wattage

4.end

5.show power inline consumption default

DETAILED STEPS

	Command or Action	Purpose
Step 1	configure terminal	Enters global configuration mode.
	Example:
	Switch# configure terminal
Step 2	no cdp run	(Optional) Disables CDP.
	Example:
	Switch(config)# no cdp run
