Ethernet, TCP/IPv4, Addressing, Subnetting, Routing, IP Services, and Quality of Service
3-Day Instructor Led Hands-On Lab Class
Available in either Web-Based Delivery or On-Site Delivery
Minimum 10 students – Maximum 16 students
Course Description
Ethernet and IPv4 are two of the fundamental technologies behind modern networking. Whether traffic is crossing a local network, accessing an application, reaching a cloud service, or traveling across a service-provider infrastructure, network professionals need to understand what happens at both the Ethernet and IP layers.
CSI-HO-001-B is a three-day hands-on course designed to build that understanding.
The course takes a systems approach to Ethernet and TCP/IP networking, helping students understand how the individual protocols, addressing mechanisms, network devices, and services work together to deliver communications from one endpoint to another.
Students begin with the layered model of networking and Ethernet fundamentals before progressing into TCP and UDP, IPv4 addressing and subnetting, routing, network services, troubleshooting, and Quality of Service.
Instructor-led explanation is reinforced with hands-on exercises using Cisco-based networking systems and network configuration tools. Students configure, observe, verify, and troubleshoot the technologies discussed throughout the course.
Rather than simply memorizing terminology, addresses, subnetting procedures, or configuration commands, students learn how Ethernet and IPv4 networks actually operate and how to prove what the network is doing.
Throughout the course, students explore practical questions such as:
- How do the OSI and TCP/IP models help explain network communications?
- How does Ethernet move frames across a LAN?
- How do Ethernet switches learn MAC addresses?
- How does ARP connect Ethernet MAC addresses with IPv4 addresses?
- Why are VLANs used and how does IEEE 802.1Q trunking work?
- Why is Spanning Tree Protocol necessary?
- What roles do TCP and UDP play in application communications?
- How does IPv4 addressing work?
- How do I calculate and design IPv4 subnets?
- What are DHCP and DNS doing behind the scenes?
- How does a router determine where to forward an IP packet?
- What is the difference between interior and exterior routing?
- How do OSPF and BGP exchange network reachability information?
- How do I approach troubleshooting an IP network?
- How do default gateways, translation, and port forwarding affect traffic?
- How does IP multicast differ from unicast?
- What networking requirements are created by voice and video applications?
- Why does Quality of Service matter?
- How do scheduling, marking, and policing affect network traffic?

Audience
This course is designed for technical professionals who need a practical understanding of Ethernet and TCP/IP networking.
Ideal participants include:
- Broadband and Service Provider Technicians
- Field Technicians
- Central Office Technicians
- Network Engineers
- Network Administrators
- Network Operations Center personnel
- Customer Support and Technical Support personnel
- Network Design Engineers
- Systems Engineers
- Development and Test Engineers
- Network Management personnel
- IT Professionals
- Technical Sales Engineers
- Technical Marketing personnel
- Individuals preparing for networking certifications
- Anyone moving into a networking-focused technical role
The course is particularly valuable for anyone who needs to understand both the Layer 2 Ethernet network and the Layer 3 IPv4 network rather than treating them as separate technologies.
That combined understanding is especially useful when installing, supporting, operating, or troubleshooting networks because a problem observed at one layer may actually originate at another.
Course Prerequisites
No previous in-depth knowledge of Ethernet or TCP/IP is required.
Some general familiarity with computers, networking, telecommunications, or IT is helpful, but the course builds the necessary networking knowledge beginning with the fundamentals.
Because this is a hands-on course, students will work with network devices, configuration interfaces, addressing exercises, routing protocols, and lab systems throughout the class.
Students participating remotely should have a computer capable of connecting to the provided lab environment.
For on-site classes, students should bring a laptop computer unless suitable classroom computers are being provided.
Course Materials
Students receive:
- Course Student Guide
- Access to the course networking lab environment
- Ethernet hands-on exercises
- IPv4 addressing and subnetting exercises
- Routing exercises
- Troubleshooting exercises
- Quality of Service exercises
The combination of instructor explanation, reference material, configuration exercises, and hands-on experimentation is designed to reinforce both conceptual understanding and practical networking skills.
The Hands-On Approach
Networking becomes much easier to understand when students can see the protocols and technologies operate.
Throughout this course, students move beyond definitions and diagrams by working directly with Ethernet and IP networking concepts. They examine addressing, configure network devices, build subnets, establish routing, verify operation, and investigate network behavior.
The labs reinforce an important engineering habit:
Do not simply assume what the network is doing—verify it.
Students learn to use configuration information, operational results, addressing information, routing information, and observed network behavior to determine whether the network is operating correctly.
This combination of knowledge, hands-on experimentation, and verification helps turn networking concepts into practical skills.

Why Take This Course?
Ethernet and IPv4 do not operate independently.
Before an IPv4 packet can normally reach another device on an Ethernet LAN, the system must understand whether the destination is local or remote, determine the appropriate Layer 2 destination, and deliver the packet within an Ethernet frame. When the destination is on another network, routers, routing tables, addressing, and routing protocols become part of that communication path.
Problems can therefore cross layers.
A VLAN problem can appear to be an IP problem. An ARP problem can prevent an otherwise correctly addressed device from communicating. An incorrect subnet mask can look like a routing failure. A DNS problem can appear to be an application or Internet connectivity problem.
Understanding these relationships is one of the keys to effective networking and troubleshooting.
CSI-HO-001-B develops that broader perspective by teaching students to connect the dots from Ethernet through TCP/IP, routing, applications, and IP services.
