What does the term "multi-chassis LAG" refer to in the context of AOS-CX switches?

The term "multi-chassis LAG" refers specifically to a technique for linking multiple switches in such a manner that they operate as a single virtual switch. This approach allows for aggregation of multiple physical links across different switches, effectively treating them as one logical link. By doing so, it enhances bandwidth and provides redundancy, enabling seamless data flow and improved performance across a network.

In a multi-chassis LAG configuration, if one switch fails, the traffic can continue to flow through the remaining switches without interruption. This method is particularly useful in network designs that require high availability and resilience, as it minimizes the risk of a single point of failure.

The other choices do not accurately describe the concept of multi-chassis LAG. For instance, grouping ports on a single switch pertains to port aggregation within a single device rather than across multiple switches. Load balancing and seamless failover are important aspects of network design but do not specifically capture the essence of multi-chassis LAG, which focuses on the virtualization of multiple switches into a unified operational entity.
