Learning Objectives
- Find and Correct Network Errors
- Document the Corrected Network
Introduction
In this activity, you will practice troubleshooting a misconfigured VLAN environment. The initial network has errors. Your objective is to locate and correct any and all errors in the configurations and establish end-to-end connectivity. Your final configuration should match the topology diagram and addressing table. All passwords are set to cisco, except the enable secret password, which is set to class.
Task 1: Find and Correct Network Errors
Once all errors are corrected, PCs belonging to the same VLAN should be able to ping each other. In addition, S1, S2, and S3 should be able to ping each other.
