What Are VLAN Types?
Let’s cut to the chase: VLANs help you divide a single switch into smart zones without extra wires. Think of it like having separate rooms in a flat, each with its own purpose. That’s exactly why these 5 VLAN Types matter if you have IP cameras, smart gadgets, or a dual-ISP home setup.
🧱 1. Default VLAN
- What it is: The “catch-all” network that every port belongs to when you first power on a switch.
- Why watch out: It’s like leaving every room’s door unlocked. Once you’re ready, change it to avoid open access.
📦 2. Data VLAN
- What it handles: Daily stuff you use PCs, smart TVs, phones.
- Why it matters: Keeps your everyday devices separate and secure.
- Example: VLAN 10 (Work Devices) using 192.168.10.0/24 is a perfect start.
📞 3. Voice VLAN
- What it serves: Call and conference traffic Zoom, SIP phones, intercoms.
- Why it’s special: Made for smooth, uninterrupted calls thanks to built-in QoS.
🛠️ 4. Management VLAN
- Purpose: A private lane for admin tasks logging into your ER605, switch GUI, etc.
- Pro tip: Only your admin laptop or PC should be on this VLAN. Others don’t need access.
🌐 5. Guest VLAN
- Created for: Visitors, clients, or contractors using your Wi-Fi.
- What it does: Gives internet access but strips out access to your LAN and internal drives.
- Example: VLAN 40, set to 192.168.40.0/24, keeps non-trusted devices off your critical gear.
