Networking Fundamentals Through an Aruba Lens

Part 1 of this series builds a full networking foundation before narrowing in on Aruba-specific solutions. It starts with core concepts like the OSI model, encapsulation, and binary and hexadecimal numbering, then moves into the TCP/IP stack, including Ethernet framing, IPv4 and TCP/UDP headers, and the three-way handshake. From there it covers Aruba's switching portfolio and AOS-CX features before finishing with VLANs, trunk ports, and how forwarding tables and frame delivery actually work.

Who It's For

Aimed at students who are new to technology or networking, this course is also positioned as preparation for the Aruba Certified Network Technician (ACNT) exam, with Part 2 continuing into IPv4 routing and wireless LAN theory.

Key Takeaways

Core networking concepts: the OSI model, TCP/IP stack, and key protocol headers
An introduction to Aruba's switching portfolio and AOS-CX commands
How VLANs, trunk ports, and forwarding tables control traffic on a network
