This document details the transition from a 20/80 to an 80/20 architecture focusing on the access and distribution layers using core switches. It outlines the configuration for various FastEthernet and GigabitEthernet interfaces, emphasizing the setup for VLANs, including the important configurations related to IP addressing and trunk/access switch modes. With practical examples, it highlights the no IP address configurations and necessary settings for switches, delivering a comprehensive guide to network administrators aiming for optimized network design and functionality.
