Explanation

The aggregation layer operates at Layer 2 only, and the core provides Layer 2 and Layer 3 functions is not a use case for implementing Virtual Switching Extension (VSX) at the core for a data center that has a three-tier topology with ArubaOS-CX switches at each layer. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSX can be implemented at any layer of the data center network, but it is more common to implement it at the aggregation or leaf layer, where it can provide Layer 2 and Layer 3 functions. The core layer typically operates at Layer 3 only and does not require VSX.
