Configuring a Power Management Mode on a PoE Port

PoE commands are supported only when the switch is running the LAN base image. Power over Ethernet

Plus (PoE+) is supported only on Catalyst 2960-S switches.

For most situations, the default configuration (auto mode) works well, providing plug-and-play

operation. No further configuration is required. However, use the following procedure to give a PoE port

higher priority, to make it data only, or to specify a maximum wattage to disallow high-power powered

devices on a port.

When you make PoE configuration changes, the port being configured drops power. Depending on the

new configuration, the state of the other PoE ports, and the state of the power budget, the port might not

be powered up again. For example, port 1 is in the auto and on state, and you configure it for static mode.

The switch removes power from port 1, detects the powered device, and repowers the port. If port 1 is

in the auto and on state and you configure it with a maximum wattage of 10 W, the switch removes power

from the port and then redetects the powered device. The switch repowers the port only if the powered

device is a Class 1, Class 2, or a Cisco-only powered device.

Beginning in privileged EXEC mode, follow these steps to configure a power management mode on a

PoE-capable port:

configure terminal

interface interface-id

Enter global configuration mode.

Specify the physical port to be configured, and enter interface

configuration mode.
