Grandstream GWN7816 48‑Port Layer 3 Managed Switch | 6x 10G SFP+, Stackable

Grandstream GWN7816: Enterprise‑Grade Layer 3 Switch for High‑Density Networks

The Grandstream GWN7816 is a 48‑port Layer 3 managed network switch engineered for enterprises that demand scalable, secure and high‑performance network infrastructure. As the standard (non‑PoE) sibling of the GWN7816P, the GWN7816 is designed for large‑scale deployments where PoE is not required – delivering the exact same enterprise‑grade performance, routing capabilities and management options at a more accessible price point.

Massive Connectivity for Core and Distribution Layers

The GWN7816 is equipped with 48 auto‑sensing Gigabit Ethernet RJ45 ports and 6x 10‑Gigabit SFP+ ports, making it ideal for medium‑to‑large enterprises, educational campuses, hospitality networks and data centre environments. The 10G SFP+ uplinks provide high‑speed fibre backbone connectivity and support stacking for simplified management and redundant links.

Blazing Performance with Non‑Blocking Architecture

With a non‑blocking switching capacity of 216 Gbps, a forwarding rate of 160.704 Mpps and a packet buffer of 16 MB, the GWN7816 guarantees consistent, high‑performance throughput across all ports simultaneously. Network latency is kept under 4 microseconds, ensuring that real‑time applications and sensitive data transfers are never compromised.

True Layer 3 Dynamic Routing

Unlike Layer 2+ switches, the GWN7816 is a true Layer 3 switch. It supports inter‑VLAN routing, static routing and full dynamic routing protocols:

• Static routing for simple configurations.

• RIP & RIPng (Routing Information Protocol)

• OSPF & OSPFv3 (Open Shortest Path First) for efficient, scalable routing

• BGP (Border Gateway Protocol) for complex, multi‑site environments

• A large routing table of 12K IPv4 routes and 4K IPv6 routes

• Policy‑based routing (pending) and VRRP (pending) for high‑availability architectures

By routing directly on the switch, the GWN7816 eliminates the latency and bottlenecks associated with sending inter‑VLAN traffic to an external router.

Advanced Security and Attack Prevention

The GWN7816 provides a comprehensive set of enterprise‑grade security features to protect network integrity:

• Port‑based authentication, 802.1X and MAC authentication, backed by RADIUS/TACACS+ AAA servers

• DHCP Snooping and Dynamic ARP Inspection (DAI) to block spoofing and man‑in‑the‑middle attacks

• IP Source Guard to prevent IP address spoofing

• DoS attack prevention and storm control for traffic anomaly protection

• Port isolation, sticky MAC and MAC address filtering

• Secure management via HTTPS, SSH and SNMPv3

• Kensington Security Slot for physical security

Advanced Switching, VLAN and Multicast Features

The GWN7816 is built to handle complex network topologies and traffic patterns:

• 4K VLAN groups (port‑based, 802.1Q, MAC‑based, protocol‑based, QinQ and Private VLAN)

• Voice VLAN with auto‑detection – instantly applies QoS policies to IP phones

• 32 link aggregation groups (LACP) for increased bandwidth and redundancy

• Spanning Tree Protocol with 64 instances for STP/RSTP/MSTP/PVST+/RPVST+ to prevent loops

• IGMP/MLD Snooping (v2/v3) and MVR for efficient multicast distribution

• 32 VLAN virtual interfaces with 9216‑byte jumbo frame support for high‑throughput environments

Free, Centralised and Flexible Management

The GWN7816 can be managed through multiple interfaces, all at no extra cost:

• Embedded web UI – intuitive, browser‑based management

• CLI – command‑line interface for granular, scriptable control

• GDMS Networking – free cloud platform for zero‑touch provisioning, real‑time monitoring and bulk firmware upgrades across your entire Grandstream fleet (switches, routers, APs)

• GWN Manager – on‑premise software controller for enterprises that prefer local management without licence fees

Stacking support (coming soon) will allow up to 16 GWN7816 switches to be managed as a single logical unit.

Built for Enterprise Reliability

The GWN7816 is engineered for continuous uptime with features such as dual firmware images, dual system file redundancy, fault detection, link aggregation and storm control. An optional hot‑swappable RPS‑70W redundant power supply (sold separately) is available to protect against power supply failures, providing seamless failover for mission‑critical environments.
