VLAN & IP Addressing Lab
Posted
Built and maintained a hands-on networking lab environment using enterprise-grade switching equipment and Cisco Packet Tracer to practice VLAN segmentation, IP addressing schemes, and structured network troubleshooting aligned with Cisco networking fundamentals.
Project details
Configured trunk ports, access ports, and inter-VLAN routing scenarios on managed switches to create isolated network segments, simulating enterprise LAN environments where different departments or services operate on dedicated VLANs with controlled inter-segment communication.
Developed structured IP addressing plans covering subnetting, CIDR notation, and address allocation strategies for multiple VLAN segments, documenting each scheme to mirror production-grade network planning methodologies used in enterprise environments.
Created repeatable lab scenarios covering trunking configuration, VLAN assignment, static and dynamic routing integration, and basic failover testing, providing a consistent practice environment for validating networking concepts and troubleshooting common connectivity issues.
Used Cisco Packet Tracer alongside physical equipment and a Cisco network switch to bridge simulation with real-world configuration experience, reinforcing concepts such as switch port security, VLAN pruning, and spanning tree behavior in a controlled lab setting.
Work Context: At Pures College (IT Systems Support and Computer Instructor, 2024–2025), I used this VLAN and addressing workflow to coach students through practical troubleshooting in structured lab sessions.
Current Implementation: I continue extending the same scenarios in my personal home lab for repeatable segmentation, routing, and failover testing.

Project Summary
Built a hands-on networking lab using enterprise-grade switching equipment and Cisco Packet Tracer to practice VLAN segmentation, structured IP addressing plans, and inter-VLAN routing across isolated network segments.
Work Context
At Pures College (IT Systems Support and Computer Instructor, 2024–2025), this lab environment supported structured classroom delivery where students configured trunk ports, access ports, and inter-VLAN routing on managed switches. Each session followed a repeatable scenario covering VLAN assignment, IP address planning, and connectivity validation.
Current Implementation
I continue extending the same lab scenarios in a personal home lab, testing segmentation patterns, routing behavior, and failover handling across physical and simulated environments.
Results and Impact
- VLAN segments configured: 6
- Endpoints simulated: 20+
- Lab scenarios delivered: 4 (trunking, routing, addressing, failover)
Deliverables
- Lab topology diagrams and addressing plans documented per scenario
- Repeatable configuration templates for trunk port, access port, and inter-VLAN routing setups
- Troubleshooting reference covering common VLAN and addressing issues
Technical Notes
- Scenarios cover trunking configuration, VLAN pruning, spanning tree behavior, and static/dynamic routing integration.
- IP addressing plans use CIDR notation with documented subnet allocation per VLAN segment.
- Physical Cisco switch and Packet Tracer simulations are used together to bridge theory and practice.
