MC-LAG Insights

What is MC-LAG?

MC-LAG (Multi-Chassis Link Aggregation Group) is a network technology that provides link aggregation across multiple physical switches or routers. It allows a device to connect to two or more independent chassis using a single logical link, providing increased bandwidth and redundancy. If one of the chassis fails, traffic can continue to flow through the remaining active chassis.
