Aggregating multiple links between physical interfaces creates a single logical point-to-point trunk link or a LAG. The LAG balances traffic across the member links within an aggregated Ethernet bundle and effectively increases the uplink bandwidth. LACP (Link Aggregation Control Protocol): LACP is an industry-standard protocol (802. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. 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. The regular Aggregation switch is best used to connect all devices in a rack.
