Grandstream GWN7831 Layer‑3 Aggregation Managed Network Switch

Key Features:

• 24 × Gigabit SFP Ports: High‑density fiber access for deployed endpoints and distribution links.

• 4 × 10 Gbps SFP+ Uplinks: High‑speed backbone connectivity for core network aggregation.

• 4 × Combo Gigabit Ports: RJ45/SFP combo ports for flexible copper or fiber connections.

• Layer‑3 Managed: Static and dynamic routing (RIP, RIPng, OSPF, OSPFv3) with full IPv4/IPv6 support.

• 128 Gbps Switching Capacity: Delivers robust throughput for demanding enterprise environments.

• ~95.2 Mpps Forwarding Rate: Handles heavy traffic loads with minimal latency.

• Advanced VLAN & QoS: Supports up to 4,000 VLANs, voice VLANs, QoS prioritization, traffic shaping, and rate limiting.

• Comprehensive Security: ARP inspection, IP source guard, DoS protection, DHCP snooping, 802.1X, RADIUS/TACACS+, storm control, port security.

• Multicast Support: IGMP v2/v3 and MLD v1/v2 snooping for optimized multicast traffic.

• Flexible Management: Manage locally (Web UI/CLI/SNMP) or centrally via GWN.Cloud and GWN Manager.

• Redundant Power Support: Supports optional external redundant power supply (RPS) for higher uptime.

• Store‑and‑Forward Forwarding: Efficient and reliable data handling mode.
