Page 304: Mls Qos Trust
12.2(20)SE The usage guidelines were revised to describe how the switch sets the trust state when a Cisco IP Phone is connected to a switch or routed port. Usage Guidelines Packets entering a quality of service (QoS) domain are classified at the edge of the domain. When the packets are classified at the edge, the switch port within the QoS domain can be configured to one of the trusted states because there is no need to classify the packets at every switch within the domain.
Page 305: Mls Qos Trust
The trusted boundary feature prevents security problems if users disconnect their PCs from networked Cisco IP Phones and connect them to the switch port to take advantage of trusted CoS or DSCP settings. You must globally enable the Cisco Discovery Protocol (CDP) on the switch and on the port connected to the IP phone.

Use the max max-wattage option to disallow higher-power powered devices. With this configuration, when the powered device sends Cisco Discovery Protocol (CDP) messages requesting more power than the maximum wattage, the switch removes power from the port. If the powered-device IEEE class maximum is greater than the maximum wattage, the switch does not power the device.
Page 343 If a port has a Cisco powered device connected to it, you should not use the power inline never command to configure the port. A false link-up can occur on the port, placing it into an error-disabled state.
