Modern racks move serious east–west traffic VM mobility, container builds, NVMe/TCP bursts, so your Data Center Switches at the Top‑of‑Rack (ToR) must forward at line rate and scale cleanly to the spine.
The NS‑S6200 family from Network‑Switch gives you exactly that: same‑class ToR Leaf Switch platforms with 10GBASE‑T, 10G SFP+, or 25G SFP28 downlinks and 100G Uplinks via QSFP28 delivered as your product. We can customize the faceplate and logo, labels/packaging, and even ship a day‑0 “gold image” (VLAN plan, QoS/AAA, Syslog/SNMP, LACP templates).
Public series pages confirm the core hardware patterns: 48× downlinks plus 8× 100G QSFP28 on each model, 40G compatibility on the QSFP28 uplinks, large buffers, and cross‑device link aggregation (M‑LAG) for active‑active upstreams.
Product Overview
Three ways to leaf
- NS‑S6250 Switches (48× 10G SFP+ + 8× 100G QSFP28): Classic optical ToR with big buffers and 40G/100G‑compatible uplinks. Uplinks and fabric design target non‑blocking forwarding at the access edge.
- NS‑S6232 Switches (48× 25G SFP28 + 8× 100G QSFP28): 25G ToR/leaf for greenfield racks or refreshed NICs; published specs list 2.56 Tbps switching and 1904 Mpps forwarding, ample for micro‑burst loads.
- NS‑S6231 Switches (48× 10GBASE‑T + 8× 100G QSFP28): Copper ToR for server rooms still standardized on 10G RJ45, with the same 100G spine connectivity and EVPN/VXLAN support for overlay fabrics.
Why NS matters: we pre‑stage your image, LACP/LAG policy, ERPS/MSTP edge guards, QoS/AAA, and monitoring so every DC Switch turns up identical to the last under your brand.
Models Lineup at a Glance
NS model codes map 1:1 to the same‑class porting you expect. Specs (ports, uplinks, modes) come from series datasheets and product pages.
| Model (NS) | Downlinks (Leaf Ports) | Uplinks | Platform Highlights | Typical Roles |
| NS‑S6250‑48XS8CQ | 48 × SFP+ 10G | 8 × QSFP28 100G (backward‑compatible with 40G) | Large buffers, M‑LAG cross‑device aggregation; hot‑swap PSUs & modular fans | Optical ToR leaf; high‑end campus aggregation with 100G northbound |
| NS‑S6232‑48XS8CQ | 48 × SFP28 25G | 8 × QSFP28 100G | 25G access with multi‑terabit switch fabric (2.56 Tbps / 1904 Mpps) | 25G ToR leaf; 100G spine fan‑in |
| NS‑S6231‑48XT8CQ | 48 × 10GBASE‑T (RJ45) | 8 × QSFP28 100G | Copper server access; EVPN‑VXLAN fabric support; 1+1 PSU & 3+1 fan patterns common in this class | Copper ToR for mixed server rooms; appliance/service racks |
What You Can Customize?
- Exterior & branding: faceplate colorway, logo silkscreen, rear/belly labels, package inserts.
- Default config: VLAN plan, LACP on uplinks, MSTP edge guards, CoPP/CPP/NFPP, QoS/AAA order, SNMP/Syslog, login banners.
- Port‑role templates: “Server,” “Storage,” “vHost,” “OOB,” with consistent ACLs and QoS queues pre‑applied.
Why these Leaf Switches still hit the sweet spot?
- Deterministic uplinks: Each platform exposes 8× 100G QSFP28 for clean LAGs to aggregation/spine; the QSFP28 cages support 40G where needed, easing staged core upgrades.
- Buffering for bursts: Series literature highlights large buffers and scheduling tuned for micro‑bursty east–west traffic, avoiding brownouts during backup or build windows.
- Overlay‑ready fabrics: EVPN‑VXLAN support appears across the class so your policy follows the workload, not a VLAN boundary.
- Hardware serviceability: Dual hot‑swap PSUs and modular fans (typical 1+1 PSUs, 3+1 fans) make swaps unremarkable during maintenance.
Deployment Scenarios
Optical ToR with 100G spine (NS‑S6250‑48XS8CQ)
Populate one leaf per rack; downlink SFP+ to servers/NICs and uplink 2× or 4× 100G in M‑LAG bundles toward the aggregation pair. The official page calls out cross‑device link aggregation and 40G/100G uplink compatibility, which makes phased spine upgrades straightforward.
25G ToR for new compute (NS‑S6232‑48XS8CQ)
Standardize on 25G NICs at the server and run 8× 100G northbound. Published figures 2.56 Tbps / 1904 Mpps, provide headroom for micro‑services chatter and storage east–west spikes.
Copper ToR for mixed rooms (NS‑S6231‑48XT8CQ)
When 10GBASE‑T is entrenched, RJ45 keeps costs in line while 100G Uplinks deliver clean fan‑in. The Chinese product page emphasizes EVPN‑VXLAN support and ToR positioning with 100G uplinks, ideal for overlay fabrics in brownfield sites.
Appliance & service racks (any NS‑S6200 leaf)
Firewalls/IDPS, proxies, KVM, and backup heads all benefit from line‑rate ToR with QSFP28 uplinks. Use port‑role templates to lock down east–west flows and rate‑limit noisy jobs.
Software & Fabric
- L2/L3 foundation: 802.1Q VLANs, LACP, MSTP/RSTP, jumbo frames; dual‑stack routing (static, RIP/RIPng, OSPFv2/v3, IS‑IS, BGP) depending on software image, so you can run routed leaf/aggregation with policy at the edge. (Series datasheets and guides list protocol sets.)
- Fabric overlays: EVPN‑VXLAN for scalable L2 overlays and any‑to‑any L3 gateways at the leaf; telemetry hooks for modern NOC tooling.
- High availability: M‑LAG (cross‑device link aggregation) and “de‑stacking” operations for device‑level redundancy and maintenance with minimal blast radius.
- Operations: Web/CLI/SSH, SNMP, Syslog/RMON; optics telemetry; dual‑image/boot safeguards; hot‑swap PSUs and modular fans for quick serviceability.
Optics & Cabling
| Port Type | Recommended Optics / Cables | Typical Use | Notes |
| QSFP28 100G | 100G SR4/DR/FR/LR; break‑out 4×25G DAC/AOC where supported | Leaf‑to‑spine uplinks | QSFP28 uplinks in this class are backward‑compatible with 40G for staged migrations. |
| QSFP+ 40G (compat. mode) | 40G SR4/LR4; 4×10G breakout | Interim core/agg | Use when core is still at 40G; migrate to 100G later without changing leaves. |
| SFP28 25G | 25G SR/LR; some ports can run at 10G on SFP28 cages | 25G server access | Keep all SFP28 ports at the same rate per platform guidance. |
| SFP+ 10G | 10G SR/LR; DAC/AOC for short runs | Optical ToR access | Standardize optic SKUs to simplify spares. |
| 10GBASE‑T | Cat6/Cat6A | Copper ToR access | Stay ≤100 m; enable EEE on idle‑heavy links if latency budget allows. |
NS vs. Fixed‑Brand Data‑Center Switches
| Aspect | NS‑S6231 / NS‑S6232 / NS‑S6250 | Fixed‑Brand OEM | Other Third‑Party Resellers |
| Performance & Ports | Same‑class hardware: 48× 10GBASE‑T / 10G SFP+ / 25G SFP28 + 8× 100G QSFP28; large buffers | OEM‑grade, often tied to licensed optics/features | Mixed; may be re‑badged/refurb |
| Fabric & Overlays | EVPN‑VXLAN, M‑LAG, telemetry hooks | Similar features but toolchains can be proprietary | Feature claims vary by firmware |
| Customization | Exterior (logo), labels; preloaded VLAN/QoS/AAA, LACP/edge‑guards, ACL baselines | Branding/defaults fixed; minimal templateing | Cosmetic only; config after arrival |
| Serviceability | Hot‑swap PSUs (1+1) and fans (3+1) on this class | Similar, but FRUs sometimes vendor‑locked | FRU availability inconsistent |
| Pricing & TCO | Typically ~30% below OEM; ships ready‑to‑deploy | Premium list + license add‑ons | Slightly cheaper than OEM with fewer guarantees |
| Lead Time | Custom SKUs, pre‑configured at factory | Standard SKUs | Inconsistent stock; long tails |
Day‑0 to Day‑2 Operations
- Zero‑touch day‑0: We ship your image/config VLAN plan, LACP policies on QSFP28 uplinks, STP edge guards, CoPP/CPP/NFPP, SNMPv3/Syslog, and port‑role templates, so field techs just patch and power.
- Fast troubleshooting: With CLI/SSH and SNMP telemetry, optics power readouts, and dual‑image safeguards, you can diagnose remotely and swap FRUs live. Documentation for this class confirms hot‑swap PSU/fan designs and de‑stacking/M‑LAG options for low‑blast‑radius maintenance.
