EtherChannel Overview

In some cases, you might want to group multiple switch ports together for them to appear as a single port. EtherChannel port groups provide you with this ability. These port groups behave as a single logical port for high-bandwidth connections between switches or between switches and servers. An EtherChannel balances the traffic load across the links in the channel and provides redundancy in the case of a link failure within the EtherChannel by sending traffic that was previously carried over the failed link to the remaining links. You can create an EtherChannel port group by grouping multiple trunk ports into one logical trunk port or by grouping multiple access ports into one logical access port. When you configure an ...
