How to aggregate data from different switches
This article provides a comprehensive explanation of link aggregation — covering LACP, static vs dynamic link aggregation, and MLAG (Link Aggregation Plus) — along with real configuration examples from Cisco and Huawei switches. What Is Link Aggregation?Switch aggregation is transforming how networks handle data traffic. By combining multiple switches into a cohesive system, organizations can improve efficiency, scalability, and management. A round-robin algorithm is used for load balancing traffic across the interfaces in an aggregated link. This is the same as a port channel in Cisco speak, and you might hear these referred to.
