The Aruba CX 8400 Switch Series is a high-performance, modular core and aggregation switch designed for demanding campus and data center networks. It supports a variety of line cards, including modules with high-density 100GbE QSFP28 ports, making it the only option listed that provides high-speed 100GbE interconnects. The other switch series listed are primarily designed for access or aggregation roles and support lower uplink speeds, such as 10GbE, 25GbE, or 50GbE, but not 100GbE.

A. The Aruba CX 6200 is an access layer switch series that supports a maximum uplink speed of 10GbE SFP+.

C. The Aruba CX 6300 is a stackable access and aggregation switch series with uplink speeds up to 50GbE SFP56.

D. The Aruba CX 4100i is a ruggedized access switch series designed for IoT, with uplink speeds limited to 1GbE SFP.
