Which switch does Aruba recommend for an access layer role?

The Aruba CX switching portfolio is segmented by network role. The Aruba CX 6xxx series is designed for the campus access and aggregation layers, while the CX 8xxx series is intended for the core and data center layers. The Aruba CX 6100 is specifically positioned as a family of entry-level access switches, making it a direct and appropriate choice for this role. While the CX 6400 can also function at the access layer, it is a versatile modular platform also designed for aggregation and core roles. The CX 8xxx series switches are not recommended for the access layer.

B. Aruba CX 8400: This is a high-performance modular chassis switch specifically designed for the enterprise campus core and aggregation layers, not the access layer.

C. Aruba CX 8300: This series of high-performance switches is intended for campus core, aggregation, or data center Top-of-Rack (ToR) roles.

D. Aruba CX 6400: While suitable for high-density access, this modular switch is also designed for aggregation and core roles, making it a less specific answer than the dedicated access-layer CX 6100.
