Grandstream GWN7830 Layer 3 Aggregation Switch | 6x SFP + 4x 10G SFP+

Grandstream GWN7830: Scalable Layer 3 Aggregation Switch for Enterprise Networks

The Grandstream GWN7830 is a dedicated Layer 3 aggregation switch, purpose‑built to interconnect multiple access switches and provide high‑speed uplinks to the network core. It is the perfect solution for medium‑to‑large enterprises, educational campuses, and hospitality networks that need to aggregate traffic from hundreds of devices while maintaining wire‑speed performance.

Flexible, High‑Density Connectivity

The GWN7830 offers a versatile port configuration, designed specifically for aggregation roles:

• 2 x 10/100/1000 Mbps RJ‑45 ports – for out‑of‑band management, legacy device connection, or low‑bandwidth edge devices.

• 6 x Gigabit SFP ports – connect to downstream access switches (e.g., GWN7801, GWN7803) using fibre or copper SFP modules.

• 4 x 10‑Gigabit SFP+ ports – ultra‑fast uplinks to the core switch (e.g., GWN7816P) or direct connection to high‑performance servers.

With a non‑blocking switching capacity of 96 Gbps and a forwarding rate of 71.424 Mpps, the GWN7830 ensures that traffic can be forwarded on all ports simultaneously without any drop in performance.

True Layer 3 Routing for Efficient Traffic Flow

Unlike Layer 2+ aggregation switches that require a separate router for inter‑VLAN traffic, the GWN7830 can route traffic directly between VLANs. It supports:

• Static routing (32 IPv4 / 32 IPv6 routes)

• Dynamic routing protocols – RIP, RIPng, OSPF, OSPFv3, and BGP for large, complex networks

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

• A routing table of 512 IPv4 and 128 IPv6 routes (dynamic + static)

This feature eliminates the need to send traffic up to a separate router and back down, reducing latency and freeing up core router capacity.

Enterprise‑Grade Resiliency & High Availability

The GWN7830 includes several features to ensure continuous network operation:

• Stacking Support: Connect up to 16 GWN7830 switches (or mix with other GWN78xx models) and manage them as a single logical unit from one IP address, with redundant links providing automatic failover.

• Link Aggregation: Combine up to 32 port groups (LACP) to increase bandwidth and provide redundant paths between switches.

• Spanning Tree Protocols: 32 instances of STP/RSTP/MSTP/PVST+/RPVST+ to prevent loops while allowing redundant links.

• ERPS (pending): Ethernet Ring Protection Switching for sub‑50 ms recovery in ring topologies.

Comprehensive Security & Access Control

The GWN7830 provides multiple layers of security to protect your network infrastructure:

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

• Attack Prevention: DHCP Snooping, Dynamic ARP Inspection (DAI), and IP Source Guard to block spoofing and man‑in‑the‑middle attacks.

• Threat Mitigation: DoS attack prevention, storm control, port isolation, and sticky MAC filtering.

• Loop Protection: BPDU Guard, Root Guard, and loopback detection.

• Secure Management: HTTPS, SSH, SNMPv3, and user hierarchical privilege management.

Advanced QoS & Multicast Optimization

The GWN7830 includes a rich set of Quality of Service features to prioritise critical traffic (VoIP, video conferencing):

• 8 priority queues per port with scheduling algorithms: Strict Priority (SP), Weighted Round Robin (WRR), Weighted Fair Queuing (WFQ), and hybrid modes.

• Traffic shaping and rate limiting per port.

• Voice VLAN with auto‑detection (tagged/untagged OUI) for instant QoS on IP phones.

For multicast applications (IPTV, software updates), the GWN7830 offers IGMP Snooping (v2/v3) and MLD Snooping (v1/v2) with up to 256 groups each, plus Multicast VLAN Registration (MVR).

Free & Centralised Management

The GWN7830 can be managed through multiple interfaces, all at no extra cost:

• Local Web UI & CLI – for granular, on‑device control.

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

• GWN Manager – on‑premise software controller for enterprises that prefer local management (no licence fees).

All management options are completely free, keeping your total cost of ownership low.
