Description

GWN7821P Managed PoE Switch

The GWN7820 series are Layer 3 multi-gigabit managed PoE switches that allow medium-to-large enterprises to build scalable, secure, high performance and smart business networks that are fully manageable. It supports advanced VLAN for flexible and sophisticated traffic segmentation, advanced QoS for prioritization of network traffic, IGMP/MLD Snooping for network performance optimization, comprehensive security capabilities against potential attacks, and provides smart dynamic PoE output to power IP phones, IP cameras, Wi-Fi access points and other PoE endpoints.
GWN7820 series can be managed in a number of ways, including the local Web user interface of the GWN7820 series switch and CLI, the command-line interface, and GWN router. The series is also supported by GWN Series Routers, GDMS Networking and GWN Manager; Grandstream’s cloud and on-premise network management platform. With complete end-to-end quality of service and flexible security settings, the GWN7820 series are the best value enterprise-grade managed PoE switches for medium-to-large businesses.
