Why VLAN Segmentation Matters
Without VLANs, one compromised endpoint can move laterally to cameras, phones, and sometimes servers. Segmentation is one of the highest-value network fixes for SMEs.
Recommended VLAN Plan
| VLAN ID | Purpose |
|---|---|
| 10 | Corporate devices |
| 20 | Network management |
| 30 | Guest WiFi |
| 40 | CCTV and IoT |
| 50 | VoIP |

+## Safe Deployment Sequence
1. Create VLAN networks in controller
2. Define DHCP scopes per VLAN
3. Create SSIDs mapped to VLANs
4. Update switch port profiles
5. Apply firewall inter-VLAN rules
6. Migrate one department first
7. Validate printing, internet, and VoIP
Minimum Firewall Rules
- Guest VLAN -> internet only
- IoT/CCTV VLAN -> block access to corporate VLAN
- Corporate VLAN -> allow required access to servers only
- Management VLAN -> admin-only access
Post-Change Validation
| Test | Expected Result |
|---|---|
| Guest user ping corporate PC | Blocked |
| Corporate user internet access | Allowed |
| Camera stream to NVR | Allowed |
| VoIP registration | Successful |
