Grandstream GWN7811P Layer 3 Managed Switch | 8-Port PoE+, 2x 10G SFP+

Grandstream GWN7811P: High-Performance Layer 3 Managed PoE+ Switch

The Grandstream GWN7811P is a powerful Layer 3 managed PoE+ switch for enterprises that need advanced routing and switching capabilities. Whether you are building a secure campus network, a converged voice/video infrastructure, or a multi-tenant environment, the GWN7811P delivers carrier-class features in a compact, fanless metal chassis.

Power & Connectivity for Modern Edge Devices

The GWN7811P features 8 Gigabit Ethernet ports with PoE+ (802.3af/at), delivering up to 30W per port with a total budget of 120W. These ports can directly power Grandstream GWN series access points, GXV IP phones, and IP cameras without needing separate power adapters【5†L22-L24】. For high-speed uplinks or stacking, the switch includes 2 x 10 Gigabit SFP+ ports that support fibre or copper modules for long-distance connections【6†L9】. The non-blocking architecture provides 56 Gbps switching capacity and 41.644 Mpps forwarding rate, ensuring wire-speed performance on all ports simultaneously【5†L40-L41】.

Layer 3 Routing: Route Between VLANs

Unlike basic Layer 2 switches, the GWN7811P can route traffic between VLANs directly on the switch. It supports 512 IPv4 routes and 128 IPv6 routes , with 32 static routes for each protocol【6†L66-L68】. Dynamic routing protocols are also available: RIP and OSPF for IPv4, RIPng and OSPFv3 for IPv6, and BGP for advanced routing scenarios【6†L69-L70】. With 16 VLAN virtual interfaces and support for policy-based routing, the GWN7811P can serve as a distribution or core switch in a medium-sized campus, reducing latency and cost.

Enterprise Switching & Multicast

The GWN7811P supports a full suite of switching features:

• 4K VLAN groups (port-based, 802.1Q, MAC-based, protocol-based, QinQ, Private VLAN)【6†L54-L57】

• Voice VLAN with auto-detection for instant QoS on IP phones【6†L58】

• Spanning Tree Protocols (STP/RSTP/MSTP/PVST+/RPVST+) to prevent loops【6†L63】

• Link Aggregation – combines ports for higher bandwidth and redundancy

• IGMP and MLD Snooping (v2/v3) to optimise multicast traffic (e.g., iptv)【6†L73】

• Multicast VLAN Registration (MVR) – allows a single multicast stream to be shared across multiple VLANs【6†L74】

Enterprise-Grade Security

The GWN7811P includes multiple layers of protection:

• Port-based authentication with 802.1X and MAC authentication, backed by RADIUS/TACACS+ AAA【6†L78-L80】

• DHCP Snooping & Dynamic ARP Inspection (DAI) – prevents man-in-the-middle and spoofing attacks【6†L85】

• IP Source Guard – filters unauthorised IP traffic on untrusted ports【6†L84】

• DoS attack prevention, storm control, port isolation, sticky MAC filtering【6†L81-L84】

• Secure management via HTTPS, SSH, SNMPv3, and user hierarchical privilege management【6†L77】

Built for Reliability & Redundancy

The GWN7811P supports stacking, allowing up to 16 switches to be managed as a single logical unit, simplifying administration and providing redundant links between devices. The fanless metal chassis operates silently, making it ideal for open office environments. It also includes a Kensington lock slot for physical security【6†L87-L88】.

Free & Flexible Management

The GWN7811P is part of Grandstream‘s free management ecosystem:

• Embedded web interface – intuitive local management accessible via any browser.

• GDMS Networking – cloud platform for zero-touch provisioning, real‑time monitoring, and bulk firmware updates across thousands of switches, routers, and APs.

• GWN Manager – on‑premise software controller for enterprises that prefer local management.
