AR-CXF: ArubaOS-CX Switching Fundamentals (Delivered by Fast Lane)

What is a network?

What is a Protocol?

OSI Reference Model

Encapsulation, frames, packets, segments

Layer 2 to Layer 7 headers

Media, cabling, Ethernet/wifi headers

Binary/Hex/Decimal theory and conversion

TCP/IP Stack (IP addressing & Transport Protocols TCP/UDP)

Types of traffic: Unicast, Broadcast, Multicast

Overview

Ethernet frames

IPv4 Header

TCP Header ? Three-way Handshake

TCP Header ? Sequence Numbers

TCP Header ? Port Numbers

TCP Header

UPD Header

Networking devices: Switches, Routers, Multilayer Switches, APs, Mobility Controllers, Firewalls, Servers (HTTP, DHCP, DNS, Telnet, FTP)

2-Tier vs 3-Tier hierarchy

Switching Portfolio (AOS switches & AOS-CX switches) is this introducing both portfolio on a couple of slide and few slides on AOS-CX hardware architecture, software architecture and intro to NAE high level.
