The LAG balances traffic across the member links within an aggregated Ethernet bundle and effectively increases the uplink bandwidth. Another advantage of link aggregation is increased availability, because the LAG is composed of multiple member links. It helps in managing higher traffic loads between switches. Switch-to-Client Aggregation: This is beneficial. An Aggregation or "Top-of-Rack" switch is designed to connect everything in a rack at high speeds, then have an even bigger pipe out to the rest of the network. 3ad link aggregation enables you to group Ethernet interfaces to form a single link layer interface, also known as a link aggregation group (LAG) or bundle. This increases the total available bandwidth, provides redundancy in case of link failure, and ensures more stable wired performance in. This document describes the concepts of stacking and Multichassis Link Aggregation Group (M-LAG), their functions on the network, as well as their differences.
