HPE Aruba Networking AOS-CX and ACP: official blueprint for multi-vendor engineers

Modern campus and data centers are increasingly multi-vendor. HPE Aruba Networking outgrew its wireless niche and now competes head to head with Cisco in campus and DC. Here is the official path for a Cisco engineer to become productive on AOS-CX.

Official Aruba Switching track

• ACA — Aruba Certified Associate – Switching: AOS-CX fundamentals, VLAN, spanning-tree, basic OSPF.
• ACP — Aruba Certified Professional – Switching: VSX, EVPN-VXLAN, BGP, multicast, QoS, NAE.
• ACX — Aruba Certified Expert – Campus Network: end-to-end design and troubleshooting.

ACP-Switching topics a Cisco engineer must study

• VSX — Aruba's vPC equivalent with an active gateway model.
• EVPN-VXLAN — standard overlay for modern DC and campus.
• BGP underlay with unnumbered — modern spine-leaf design.
• NAE — telemetry and Python scripts running on the switch.
• REST API and OVSDB — native AOS-CX automation.
• QoS and ACL CLI — Cisco-like syntax with notable differences.

8-week plan for a CCNP

1. 1 — AOS-CX vocabulary, context vs Cisco IOS-XE.
2. 2 — Interfaces, VLAN, LAG, spanning-tree.
3. 3 — OSPF and BGP routing.
4. 4 — VSX (active gateway, ISL, keepalive).
5. 5 — EVPN-VXLAN underlay + overlay.
6. 6 — Multicast, QoS, ACL.
7. 7 — NAE, REST API and automation.
8. 8 — Review against the official exam blueprint.
