Grandstream Enterprise Layer 3 Managed Aggregation Switch, 24 x SFP, 4 x SFP/GigE Combo, 4 x SFP+, Redundant PSU

 

GR-GWN7831

 

The GWN7830 Series are Layer 3 aggregation managed switches that allow 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 GWN7830 series can be managed in several ways, including the local Web user interface of the switch, and CLI, the command line interface. This series 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.

Powerful Business Processing Capabilities

• Routing including static routing, dynamic routing and policy routing to realize routing data communication between different network segments. Simpler, more efficient and more reliable.

• DHCP Server and Relay to assign IP addresses to hosts in the network.

• GVRP(pending) to realize VLAN dynamic distribution, registration and attribute propagation, reduce the amount of manual configuration, and ensure the correctness of configuration.

• QoS, including Port Priority, Priority Mapping, Queue Scheduling, Traffic Shaping and Rate Limit.

• ACL to realize the filtering of data packets by configuring matching rules, processing operations and schedules, and providing flexible security access control policies.

• IGMP Snooping and MLD Snooping to meet the needs of multi-terminal HD video surveillance and video conference.

• IPv6 to meet the needs of the network transition from IPv4 to IPv6.

 

Multiple Security Prevention Mechanism

• Static MAC table, dynamic MAC table to allow data transmission, and filter MAC table to avoid network attacks.

• Packet filtering based on binding of IP address, MAC address, VLAN and port.

• Dynamic ARP Inspection to protect against ARP spoofing and ARP flooding attacks such as gateway spoofing, man-in-the-middle attacks, etc., common in LAN environments.

• IP Source Guard to prevent illegal address spoofing including IP/MAC/VLAN spoofing and IP/VLAN spoofing.

• DoS Attack Defense, including Land Attack, Smurf Attack, TCP SYN Attack, Ping Flooding and more.

• 802.1X, RADIUS, AAA, and TACACS+ authentications to provide authentication function for LAN devices.

• Supports port security. When the number of MAC addresses learned by a port reaches the maximum number, it will be set to error-down status automatically or stop learning to prevent MAC address attacks and control the network traffic of the port.

• Supports DHCP Snooping. Only allow DHCP packets from trusted ports to keep the enterprise DHCP environment safe.

 

Diverse Reliability Protection

• RPS, External redundant power module(optional), ensures stable business use continuously.

• Support fault detection and alarm for power supply and fan, and automatically adjust the fan speed based on temperature changes to better adapt to the environment.

• Multiple reliability protection at the device level, such as overcurrent protection, overvoltage protection, overheat technology and 6KV surge protection.

• Dual boot of hardware level. Use two FLASH chips to store boot software(system boot program), achieve hardware-level boot redundancy backup, and avoid switching failure due to FLASH chip failures.

• Dual system file redundancy backup ensures the normal startup and operation of the system and improves the stability of the device.

• STP/RSTP/MSTP to guarantee fast convergence, improve fault tolerance, ensure a stable network and provide link load balance, and redundancy.

• Compatible with PVST/PVST+(pending) for faster convergence. Optimizing network performance through VLAN-based network load balance.

• ERPS(pending), loopback detection to identify and remove loops on the network.

• VRRP(pending) to minimize network downtime caused by gateway failure.

• Link aggregation to increase bandwidth, and improve reliability and load balancing.

• Storm control to prevent traffic interruption caused by broadcast, multicast or certain unicast packets.

 

Easy Management and Maintenance

• Managed by Web GUI, CLI(Console, Telnet, SSH) and SNMP(v1/v2c/v3).

• Monitoring of CPU and memory usage. Support common networking tools such as Ping, Traceroute, UDLD(TBD) and Copper Test to analysis networking issues.

• Supports RMON, Syslog, traffic statistics and sFlow(pending) for network optimization.

• LLDP and LLDP-MED for automatic discovery, provisioning and management of endpoint devices.

• Managed by GWN.Cloud and GWN Manager.

 

Power & Green Energy Efficiency

• High-efficiency power supply module, higher efficiency of the power supply system

• All Ethernet ports support EEE(Energy Efficient Ethernet), fast transitions between normal operation and low power states with low traffic and low power consumption

• Intelligent control of fan speed based on environmental temperature. 

• Precise temperature control, energy saving and noise reduction.

 

IPv4/IPv6 Dual Protocol Stack

• IPv4 routing protocol, including IPv4 unicast routing to satisfy different networking needs.

• IPv6 routing protocols, including IPv6 unicast routing to satisfy different networking needs.

• Supports IPv6 static routing, RIPng, OSPFv3 and IPv6 multicast to meet the requirements of IPv6 independent networking and IPv4/IPv6 hybrid networking.
