About this listen
Sometimes network issues stem from the basics: incorrect VLAN assignment, disabled interfaces, or outdated configurations. This episode walks through foundational network checks that resolve a surprising number of connectivity issues. You'll learn how to verify trunk ports, check interface status, review MAC address tables, and ensure endpoints are in the correct VLAN.
We also cover configuration drift—when devices slowly fall out of sync due to manual changes or failed updates. This type of issue is common in growing networks and easy to overlook. The key takeaway? Don’t skip the basics. This episode shows how a few quick checks can save hours of troubleshooting.
