Grandstream GWN7832 Layer 3 Aggregation Switch | 12 x 10G SFP+, Stacking & Dual PSU
Grandstream GWN7832: High‑Density 10G Fibre Aggregation for the Enterprise Core
The Grandstream GWN7832 is the most powerful aggregation switch in the GWN7830 Series, designed to act as the fibre‑optic backbone of demanding enterprise networks. Whether you are aggregating traffic from dozens of access switches, connecting high‑performance servers, or building a campus‑wide fibre infrastructure, the GWN7832 delivers the raw performance, advanced Layer 3 routing, and carrier‑class resilience that modern businesses require.
Unmatched 10G Fibre Density & Performance
The GWN7832 is equipped with 12 x 10‑Gigabit SFP+ ports, providing a total switching capacity of 240 Gbps and a non‑blocking throughput of 120 Gbps – ensuring every 10G link can operate at full wire speed simultaneously. The forwarding rate of 80.352 Mpps guarantees that even the most demanding traffic loads, such as data centre backups or 4K surveillance streams, are processed without a single dropped packet.
True Layer 3 Routing for Efficient Network Designs
Unlike Layer 2+ aggregation switches that force all inter‑VLAN traffic through an external router, the GWN7832 routes directly on‑device. It supports:
-
Static routing for simple inter‑VLAN configurations,
-
Dynamic routing protocols including RIP & RIPng, OSPF & OSPFv3, and BGP for complex, multi‑site topologies,
-
A routing table of 512 IPv4 routes and 128 IPv6 routes ,
-
Policy‑based routing (pending) and VRRP (pending) for high‑availability, load‑balanced network cores.
This built‑in routing capability drastically reduces latency, frees up core router resources and simplifies network architecture.
Carrier‑Class Availability: Dual PSU & Stacking
For mission‑critical networks, the GWN7832 supports dual‑redundant power supplies. A second RPS‑60W‑B unit can be added (sold separately) to provide seamless failover if a power supply fails, ensuring uninterrupted operation. The physical chassis dimensions are fixed for 1U rack‑mounting, but the external redundant PSU is a separate box that occupies an additional 1U of rack space when installed. In addition, stacking (coming soon) will allow up to 16 switches to be managed as a single, logical unit with redundant links for automatic failover.
Advanced Security & Traffic Optimisation
The GWN7832 provides multiple layers of protection:
-
Port‑based authentication with 802.1X and MAC authentication, backed by RADIUS/TACACS+ AAA,
-
DHCP Snooping, Dynamic ARP Inspection (DAI) and IP Source Guard to block common man‑in‑the‑middle attacks,
-
DoS attack prevention, storm control, port isolation and sticky MAC filtering,
-
Loop protection including BPDU Guard, Root Guard and loopback detection.
For traffic optimisation, the switch offers 4K VLAN groups (port‑based, 802.1Q tagging, private VLAN, QinQ), auto Voice VLAN for instant QoS on IP phones, and advanced QoS with eight priority queues per port and multiple scheduling algorithms (SP, WRR, WFQ, SP+WRR, SP+WFQ).
Built for Fibre‑First Environments
The GWN7832 is a pure fibre switch – it has no copper RJ45 ports . All 12 ports are SFP+ slots that support 1G SFP and 10G SFP+ modules (fibre or copper), making it the ideal choice for:
-
High‑density fibre aggregation – connecting multiple access switches via fibre uplinks,
-
Data centre TOR (Top‑of‑Rack) – direct 10G connections to servers with SFP+ NICs,
-
Campus backbones – long‑distance fibre links between buildings without signal degradation,
-
Large‑scale surveillance – aggregating streams from hundreds of 4K IP cameras.
Free & Centralised Management
The GWN7832 integrates seamlessly into Grandstream‘s cost‑free management ecosystem:
-
GDMS Networking – cloud platform for zero‑touch provisioning, real‑time monitoring and bulk firmware upgrades across your entire fleet of switches, routers and Wi‑Fi APs,
-
GWN Manager – on‑premise software controller for enterprises that require local management,
-
Local Web UI & CLI – for granular, on‑device control.
All management options are completely free of licensing fees, keeping your total cost of ownership low.

Frequently Asked Questions
Q1: What is the primary use case for the GWN7832 in a business network? +
The GWN7832 is designed as a pure‑fibre aggregation switch in the core or distribution layer of a network. It connects multiple access switches (e.g., GWN7801P, GWN7803) via its 12 SFP+ ports, aggregates their traffic, and forwards it at 10G speeds to the core network. Its Layer 3 routing capabilities allow it to route traffic directly between VLANs – perfect for large campuses, data centres and high‑density surveillance deployments. The unit must be installed in a 19‑inch rack and requires at least one 10G SFP+ module to function; it cannot be used as a standalone desktop switch.
Q2: Does the GWN7832 support Power over Ethernet (PoE)? +
No. The GWN7832 is a fibre‑only aggregation switch and does not provide PoE. For PoE, pair it with access switches such as the GWN7806P (48 ports, 400W) or GWN7811P (8 ports, 120W).
Q3: What SFP/SFP+ modules can be used with the GWN7832? +
The GWN7832 accepts standard SFP and SFP+ modules: 10G SFP+ modules – SM‑10G (single‑mode), MM‑10G (multi‑mode) and RJ45‑10G (copper). The maximum number of RJ45‑10G modules is 6, and they must be installed with at least one empty port between them for proper cooling. 1G SFP modules – any standard 1000BASE‑SX/LX fibre modules or RJ45 copper SFP modules. DAC cables (passive copper) – supported for distances ≤ 5 m.
Q4: How does the GWN7832 handle a power supply failure? Does it work with Pakistan’s 220 V grid? +
The switch has a built‑in 60W PSU with universal AC input (100‑240 VAC, 50‑60 Hz), so it works seamlessly on Pakistan‘s standard 220 V/50 Hz grid. For redundancy, an external RPS‑60W‑B unit is available (sold separately). In the event of a main PSU failure, the RPS unit automatically takes over, ensuring uninterrupted network operation. The external RPS is physically separate (1U) and must be rack‑mounted adjacent to the GWN7832.
