The ArubaOS-Switch is the new brand name of what actually is the legacy ProCurve Switches' operating system (read: ProVision), actually this means that those (formerly HPE, actually Aruba branded) switch series are based on ArubaOS-Switch:
- 2530 (YA/YB)
- 2620 (RA)
- 2920 (WB)
- 2930F (WC)
- 3500/5400 (K)
- 3800 (KA)
- 3810/5400R (KB)
Note how single letter/double letters represent the respective Software Branch, as it happened with ProVision OS (this mean that if you're looking for very specific informations about Aruba 2920 you need to focus on "WB" Branch related documentation available through HPE Support portal).
HPE has a dedicated (ProVision/ProCurve so also ArubaOS-Switch) community here.
