Networking & Network Security
Core Aruba and networking paths for teams standardizing campus switching, wireless, network fundamentals, observability, and troubleshooting.
Training architecture
Start with TCP/IP, cabling, OSI, VLANs, and Wireshark, then build Aruba switching and wireless skills for the teams operating campus and edge networks.
Certification tier
Give junior network engineers and cross-trained admins the basics: TCP/IP, cabling, OSI, ports, protocols, VLANs, and lab practice.
Foundational networking concepts for teams building shared vocabulary before vendor-specific specialization.
Switching and VLAN design for teams supporting campus networks and segmented enterprise environments.
Certification tier
Develop the engineers responsible for Aruba switching, business wireless, RF, Wireshark analysis, and day-to-day network troubleshooting.
Associate and professional Aruba switching certification paths for teams running HPE Aruba campus infrastructure.
Wireless administration, design, security, RF technologies, IoT, and analysis for campus and edge teams.
Packet analysis and observability skills for troubleshooting application and network performance issues.
Certification tier
Develop the senior bench for network design, BGP/MPLS, server-adjacent networking, power, and operational troubleshooting.
BGP, MPLS, network design, and topology planning for engineers owning larger enterprise networks.
Server-adjacent fundamentals, power, hardware installation, and troubleshooting for teams that support the physical network edge.
Networking training is easiest to manage when it maps to production ownership: switching, wireless, routing, packet analysis, and operational troubleshooting.
Role-based paths
Match Aruba & Networking training to the actual roles your team holds. Each path bundles the right cert tracks plus the operational depth engineers need day-to-day.
