Compared to access switches, aggregation switches typically offer higher performance, faster port speeds, and more powerful processing capabilities. It does this by splitting traffic across multiple ports instead of forcing clients to use a single uplink port on a switch. The following list details the basic. IEEE 802. 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. It increases bandwidth in homes and data centers.
