VLAN 27 — Guest Network (1 device)
- Port 26: D6ED0F-4C5D00
VLAN 28 — Management Network (~35 devices)
The switch itself plus wired management clients:
VLAN Traffic Flow Summary
VLAN 28 — Management Network
- Direct access: ~6 devices on Gi ports (local management clients)
- Uplink path: ~4 devices via EX0/26 to Aruba uplink
- Total visible: ~10 devices across both switches
VLAN 29 — Home Automation / IoT
- Direct access: ~45 devices on Gi ports (primary access)
- Uplink path: ~13 devices via EX0/26 (visible from Aruba side)
- Total visible: ~58 IoT/Home Assistant devices
VLAN 30 — LAN User Network
- Direct access: ~21 devices on Gi ports (user devices)
- Uplink path: ~5 devices via EX0/26
- Total visible: ~26 user/client devices
VLAN 31 — DMZ
- Uplink only: ~4 devices accessible via EX0/26
- These are external-facing services (AdGuard DNS, etc.)
Ring Topology Benefits
- Redundancy: If one uplink fails, MRP reroutes traffic through alternate path
- Single point of failure: Only router/firewall is single point
- Load balancing: Traffic can load-balance across ring links
Device Accessibility Map
Devices on EX0/26 port (Siemens uplink) are also visible from Aruba switch (and vice versa), meaning:
- Failover to alternate path is automatic
- No configuration changes needed for redundancy
- Devices appear in both MAC tables when reachable via either path
Combined Network Summary
| Switch | Total Devices Visible | Uplink Connections |
|---|---|---|
| Aruba JL253A | ~159 devices (from MAC table) | 1 to router, 1 to Siemens |
| Siemens XR326-2C | ~99 devices (from MAC table) | 1 to Aruba, rest to local devices |
