VLAN Segmentation on Factory Floors: Isolating Machine Cells with Cisco Stratix & Hirschmann

Designing robust Layer 2 virtual local area networks (VLANs) for manufacturing facilities: 802.1Q trunking, segregating safety, HMI, and machine I/O domains.

  • A flat factory network allows broadcast storms, accidental duplicate IP conflicts, and malware to spread uncontrollably.
  • Segregate traffic into dedicated VLANs: VLAN 10 (Safety/Motion), VLAN 20 (PLC I/O), VLAN 30 (HMI/SCADA), VLAN 40 (Management).
  • 802.1Q trunk links carry multiple tagged VLANs between core distribution switches and cell switches.
