🏢 VLANs: Creating Networks Within Networks
VLANs are one of those topics that seem complicated until they suddenly click. Let's make that happen today.
Why VLANs Exist:
Without VLANs, you'd need a separate physical switch for every broadcast domain. That's expensive and inefficient. VLANs let you create logical segmentation on a single switch.
The Business Case:
- HR Department: Needs privacy for sensitive data
- Guest WiFi: Should be isolated from corporate resources
- VoIP Phones: Require QoS prioritization
- Finance: Must comply with data separation requirements
One switch, four VLANs, four broadcast domains. Problem solved.
