Traffic cannot be forwarded between protected ports at L2, all traffic passing between protected ports must be forwarded through an L3 device. Switch(config-if)# switchport protected

Chapter 2 74 © 2007 – 2010, Cisco Systems, Inc. All rights reserved. Cisco Public EtherChannel Technology Up to 8 physical links can be bundled into a single logical EtherChannel link. Usually EtherChannel is used for trunk links. Configuration applied to port channel interface affects all physical interfaces assigned to the port channel. Load balancing takes place between the physical links in an EtherChannel. EtherChannels can be L2 or L3 interfaces.
