Learn how to configure a Cisco Switch Link Aggregation using the command-line, by following this simple step-by-step tutorial, you will be able to create a new Link aggregation and configure the link aggregation in access mode or as a trunk that allows the. Port aggregation allows you to group multiple physical ports into one unit. Port aggregation is useful for implementing load balancing and provides a redundant link backup. The following list details the basic. We have learned LACP (Link Aggregation Control Protocol) and Link Aggregation before detailly. In this lesson we will focus LACP Cisco Configuration. In our Cisco LACP Example, we will bundle two links between two routers into one. In this article we will describe how to configure both LACP and PAgP EtherChannels on Cisco switches. An EtherChannel is a Link Aggregation technology whereby two switches are connected together with multiple interfaces which are bundled together to form a single logical interface (“Port-Channel”). Port Aggregation Protocol (PAgP) is a Cisco proprietary protocol for EtherChannel Configurations. It dynamically adds and manages interfaces in an EtherChannel.
