The right Aruba CX switch depends on whether it will be used for access, aggregation, core or data-centre networking, along with requirements such as port density, PoE, uplink speed and stacking. Common families include the CX 6100, 6200, 6300, 6400, 8100, 8320, 8325, 8360 and 9300 series. Aruba documents different capabilities across the AOS-CX families; for example, stacking support varies by platform.
