Advanced AOS-CX Switching (AAXSTS)

As organisations add users, applications and sites, the campus network quietly becomes one of their most critical systems. Core banking, student services, video conferencing and cloud applications all depend on it, and each new requirement adds routing, segmentation and performance decisions that a professional-level engineer may not have faced before.

Advanced AOS-CX Switching training in Ethiopia prepares experienced engineers to make those decisions with confidence. The AAXSTS course spends five instructor-led days on HPE Aruba Networking AOS-CX switches, with half the time in hands-on labs. Learners design two-tier and three-tier networks, troubleshoot with a proven method, and implement VSX, OSPF, BGP, route redistribution, VRFs, multicast, QoS, Dynamic Segmentation, and network security. The course also prepares engineers for the ACX – Switching certification exams.

Course Structure and Key Details

The course lasts five days, is led by an instructor and is available in classroom and online formats. Its 12 modules are delivered through a balance of roughly 50% lecture and 50% hands-on labs.

Learners start by designing wired networks, analysing requirements and comparing two-tier and three-tier architectures along with the underlying switching and routing principles. They then learn a troubleshooting methodology supported by logging and debugging, diagnostic commands, traffic analysis, and HPE Aruba Networking Central, followed by monitoring and automation with AOS-CX automation, REST API requests, and the Network Analytics Engine.

The next part of the course builds resilience and routing depth. Learners configure and troubleshoot VSX, apply policy-based routing, troubleshoot single-area OSPF, and design multi-area OSPF. They establish BGP connections, control advertisements, tune metrics, and apply route control, then redistribute static routes into OSPF and OSPF into BGP. VRFs and route leaking complete the routing section.

The final modules focus on traffic handling and protection. Multicast routing covers IGMP, PIM-SM, static and dynamic rendezvous points, and VSX with PIM. Quality of Service covers ingress, prioritisation, DSCP remarking, queuing, scheduling and active queue management. Dynamic Segmentation uses user-based tunnelling and downloadable user roles, and network security covers ACLs, classifier policies, Control Plane Policing, user group management, TACACS+ management access, DHCP snooping, ARP inspection and MACsec.

Participants should have attended Implementing AOS-CX Switching (ICXS) or passed the ACP – Switching certification exam. The ACX – Switching exams, HPE7-A09 (written) and HPE4-A53 (practical), are separate from the course.

Course Objectives

• Plan campus network designs suited to organisational requirements.
• Troubleshoot and monitor networks with the CLI, port mirroring, NAE, IP SLA and HPE Aruba Networking Central.
• Configure and maintain VSX and supporting Layer 2 features.
• Build scalable routing with OSPF, BGP, and policy-based routing.
• Use VRFs and route redistribution to control how routes are shared.
• Implement QoS to protect voice, video, and critical applications.
• Apply Dynamic Segmentation for role-based access.
• Secure the network with ACLs, Control Plane Policing, DHCP snooping, ARP inspection, and MACsec.
