STP and EtherChannel Operation and Configuration by Ross Bagurdes

Understanding how Ethernet works in an enterprise environment is one of the most common skills required by a network engineer. In this course, STP and EtherChannel Operation and Configuration, you will learn about creating redundant layer 2 networks with spanning tree protocol. First, you will explore rapid spanning tree protocol. Next, you will discover building redundant links between switches using EtherChannel, understanding how VLAN trunking protocol works. Finally, you will wrap up by examining switch stacking with Cisco's stackwise technology. By the end of this course, you will be able to design implement redundant layer 2 networks that can converge in less than a second, as well as increase the bandwidth between switch uplinks using EtherChannel.
