Grandstream GWN7831 Layer 3 Aggregation Managed Switch

The GWN7831 is a Layer 3 aggregation managed switch that allows medium-to-large enterprises to build scalable, secure, high performance, and smart business networks that are fully manageable. It provides 4 combo ports, 24 SFP ports and 4 SFP+ ports with a maximum switching capacity of 128Gbps.

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. GWN7831 can be managed in a number of ways, including the local Web user interface of the GWN7831 switch and CLI, the command-line interface.

And 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 and flexible security settings, the GWN7831 is the best value enterprise-grade managed switch for medium-to-large businesses.
