The GWN7831 is Layer 3 aggregation managed switch that allows enterprises to build scalable, secure, high performance and smart business networks that are fully manageable and support maximum capacity. It supports advanced VLAN for flexible and sophisticated traffic segmentation, advanced QoS for prioritization of network traffic, IGMP/MLD Snooping for network performance optimization, and comprehensive security capabilities against potential attacks. The GWN7831 can be managed in several ways, including the local Web user interface of the switch, and CLI, the command line interface. This switch is also supported by GWN. Cloud and GWN Manager, Grandstream’s cloud and on-premise network management platform. With complete end-to-end quality of service, flexible security settings, and support for maximum network capacity, the GWN7830 Series provides enterprise-grade Layer 3 aggregation switches ideal for medium-to-large deployments.

Features:

• 4 combo Gigabit Ethernet ports, 24 Gigabit SFP ports, and 4 10Gigabit SFP+ ports
• Supports deployment in IPv6 and IPv4 networks
