The LACP is part of the IEEE802. 3ad standard that enables you to bundle several physical ports together to form a single logical channel. LACP enables a network device, such as a switch, to negotiate an automatic bundling of links by sending LACP packets to the peer device. This feature helps improve the cost effectiveness of a device by increasing cumulative bandwidth without necessarily requiring hardware. It does this by splitting traffic across multiple ports instead of forcing clients to use a single uplink port on a switch. Note that these performance improvements will only occur when multiple clients are passing traffic simultaneously through the aggregated ports. Who may be interested in. It provides a step-by-step guide on configuring LAG, including checking port status, ensuring loop guard is inactive, and setting up the link aggregation through the switch's settings menu. What is Link Aggregation (LAG)? Link Aggregation (LAG) is a technique that combines multiple network ports. A link aggregation can only exist between a pair of neighboring switches, where the switch ports that are aggregated on one switch cannot be connected to switch ports that are not aggregated on the other switch. Aggregating ports multiply the bandwidth and increase port flexibility for Sophos Switch.
