Use Cases
Five distinct deployment scenarios demonstrating the DXS-F3400-28SC's ability to span campus, data center and service-provider responsibilities without changing hardware.
Use Case 1 — Small / Medium Campus Core (VSF)
Overview: Stack multiple DXS-F3400-28SC units as a single VSF logical chassis to form the campus core. A unified management and forwarding plane simplifies distribution and services — ideal for education campuses, corporate sites and branch aggregation where operational simplicity and resilience are both critical.
Business value: Simplified single-pane management, resilient forwarding and scale-out without complexity.
| Topology Element | Details |
|---|---|
| Core device | DXS-F3400-28SC VSF stack (up to 6 units) |
| Uplinks to WAN/Core | 100G QSFP28 |
| Downlinks to distribution | 10G SFP+ |
| Key protocols | VSF, M-LAG, ERPS, BGP, OSPF |
Use Case 2 — Distribution Leaf (M-LAG or VSF Dual-homed)
Overview: Deploy in M-LAG pairs at the distribution layer to give access switches active-active forwarding and predictable convergence. Where single-pane management is preferred, VSF-based distribution simplifies lifecycle operations across multi-building campus networks.
Business value: Active-active forwarding, graceful convergence and reduced operational complexity across multi-building sites.
| Topology Element | Details |
|---|---|
| Distribution device | DXS-F3400-28SC M-LAG pair or VSF cluster |
| Uplinks to campus core | 100G QSFP28 |
| Downlinks to access | 10G SFP+ — dual-homed |
| Key protocols | M-LAG, VSF, ERPS, STP/RSTP |
Use Case 3 — Border Leaf (Micro Data Center or Testbed)
Overview: Serves as an excellent border leaf for micro-data centers, lab environments and testbeds. Provides policy demarcation, telemetry collection and high-capacity 100G uplinks — enabling fast service rollout and secure separation between test and production zones.
Business value: Policy demarcation, fast telemetry and 100G uplinks for secure zone separation and rapid service iteration.
| Topology Element | Details |
|---|---|
| Border leaf device | DXS-F3400-28SC |
| Uplinks to internet/core | 100G QSFP28 — eBGP peers |
| Downlinks to DC zones | 10G SFP+ — VRF-isolated segments |
| Key protocols | VXLAN EVPN, VRF-Lite, BGP, policy routing |
Use Case 4 — Server-farm / ToR (M-LAG Dual-homed or VSF)
Overview: Deploy as ToR for 10G server racks with 100G uplinks to spine. Use M-LAG dual-homed pairs for classic high-availability ToR with active-active server connectivity, or in VSF clusters for a virtual ToR model with simplified lifecycle operations and single-pane management.
Business value: High-availability ToR with active-active server connectivity and 100G spine uplinks — M-LAG or VSF depending on operational preference.
| Topology Element | Details |
|---|---|
| ToR device | DXS-F3400-28SC M-LAG pair or VSF cluster |
| Uplinks to spine | 100G QSFP28 — dual-homed to Spine-1 & Spine-2 |
