Explore how home networks connect to the internet via switches, routers, and modems; learn to identify IP addresses, gateways, and MAC addresses, and test connectivity with ping.
Explore Aruba switches and the Aruba X operating system, focusing on SCIEX, edge and core roles, and how modular chassis, line cards, and field-replaceable components enable enterprise networks.
Explore encapsulation across layer one to layer four, learn how data becomes a frame with MAC addresses and a frame check sequence, and see port numbers 80, 22, and 53.
Demonstrates layer two connectivity by validating mac address learning, examining the mac address table, and securing the network by shutting down unused ports on an Aruba edge switch.
Participate in a pop quiz in Aruba networking essentials to identify layer two concepts like mac addresses and frames, and differentiate edge and core lan devices (6000 series vs 8000).
Layer three, the routing layer, uses IP addresses to connect local area networks across wide area networks, determine the best path, and identify services via TCP/UDP port numbers.
Demonstrates layer three and layer four concepts by using ICMP ping from PC1 to PC3 to trigger ARP learning and MAC address table updates on a switch.
Back up the running configuration to startup configuration, verify with show running-config and show startup-config, and erase the startup configuration and reboot an Aruba CX switch.
Apply basic troubleshooting on an Aruba CX switch by configuring a username and password, using show commands, and setting a VLAN 1 interface with an IP address for management.
Explore remote management of Aruba switches via the dedicated management port, using SSH and a GUI over HTTPS. Learn to create checkpoints and roll back to saved system states.
enable the ports that were shut down on the left access switch to restore layer one connectivity between pc one and pc four, with same vlan and subnet.
Complete part one of the Aruba networking essentials closing quiz to test OSI layer 3 knowledge, IP and packets, and show practical commands for checkpoint creation and management interfaces.
explore switching fundamentals in the Aruba networking essentials series, building a two-switch topology and applying spanning tree and link aggregation to manage loops, collisions, and broadcasts.
Factory reset the switch, verify port status, and enable only the required ports (no shut). Configure an IP address and validate connectivity between pc1 and pc4 with interface status checks.
Welcome!
I'm really happy to announce that I've partnered with Aruba Education Services to bring you this free networking essentials training. Learn the basics of networking with Aruba.
Description:
In Aruba Networking Essentials, you will learn what a basic computer network is, compare local and wide area networks, use cases, and implementation types. Communication over these networks relies on protocols. Once you learn about those, you will be well on your way to understanding network communications and well prepared to learn VLANs and how to configure an Aruba OS Switch!
Audience
Typical candidates for this course are individuals who are new to networking and want to learn the basics of wired networking.
Prerequisites
There are no prerequisite, this course is foundational.
Detailed course outline
Part 1: Introduction: You will get an introduction to Aruba switches, build a basic network using a single switch, and get an understanding of what packet encapsulation is.
o Aruba Switching Introduction
o Networking in everyday life
o Networking Layers
o Basic Networking with Aruba OS-CX
Part 2: Switching: Expands the network we’ve built:
o Introduction to switching
o Factory reset, port status, IP Address configuration
This course covers a lot of basic networking technologies and there is more inside for you to learn.
All the best!
