Grandstream GWN7821P Layer 3 Managed Multi-Gigabit PoE+ Switch | 8× 2.5G Ports | 2× 10G SFP+ Uplinks

The Grandstream GWN7821P is a powerful Layer 3 managed switch designed to meet the growing demands of modern enterprise networks. Featuring 8× 2.5 Gigabit Ethernet PoE++ ports and 2× 10G SFP+ uplink ports, this switch delivers high-speed connectivity and dynamic power allocation for a wide range of PoE endpoints such as Wi-Fi 6/6E access points, IP cameras, and VoIP phones.

Grandstream GWN7821P comes with smart PoE control and support for IEEE 802.3af/at/bt standards, the GWN7821P provides up to 60W per port and a 240W total PoE budget. Layer 3 routing support includes RIP, OSPF, static routing, and future-ready options like BGP and IS-IS.

Grandstream GWN7821P has advanced security features—such as 802.1X authentication, RADIUS/TACACS+, DHCP snooping, IP source guard, and storm control—ensure network integrity and data protection. The switch also supports advanced VLAN capabilities (4K VLANs, MAC/protocol/voice VLANs) and enterprise-grade QoS with multiple queue scheduling options like SP, WRR, and WFQ.

Grandstream GWN7821P is management is flexible and intuitive, with options including a built-in web interface, CLI, or integration with Grandstream’s GWN Manager (on-premise) and GDMS Networking (cloud) platforms. Support for device stacking (up to 4 units) allows centralized management and redundancy for scalable deployments.

Grandstream GWN7821P is compact yet powerful, the GWN7821P is ideal for medium to large enterprise environments needing secure, high-performance networking with simplified centralized management.
