This article is all about how to configure EtherChannel on cisco switches. In this tutorial, we learn about how EherChannel works, how to configure EtherChannel, why we configure EtherChannel and uses of EtherChannel on cisco switches. EtherChannel is a technique in which we combine two and more than two physical interfaces (ethernet ports) of the cisco switches. After that use them as a single logical interface(port). EtherChannel provides incremental trunk speeds between Fast Ethernet, Gigabit Ethernet, and 10 Gigabit ethernet. By using EtherChannel we can combine the bandwidth of multiple ports. It also provides redundancy because if any port fails then still there is no connection loss. If one port fails then another port still active and provide communication and hence provide redundancy. Always remember that in windows EtherChannel technique is known as NIC Teaming and In Linux, this is known as Ethernet Bridging. So let’s start here how we configure EtherChannel on cisco switches.
