The Grandstream GWN7802 is part of the GWN7800 series of enterprise‑level Layer 2+ managed switches. It’s built for small‑to‑medium businesses that need:
multiple Gigabit Ethernet LAN ports,
SFP uplinks (fiber or copper),
advanced security, traffic control, and QoS features,
flexible management options (local and cloud/on‑premise).
It’s offered in both PoE and non‑PoE variants (depending on model, e.g. “GWN7802P” would indicate PoE). The switch is designed to be used in quiet environments (some models are fanless), and can be rack, wall, or desktop mounted. It provides non‑blocking switching performance suitable for demanding applications like VoIP, video streaming, security cameras, etc.
Here are the standout features of the GWN7802:
Ports & Uplinks: 16 × Gigabit RJ‑45 Ethernet ports + 4 × Gigabit SFP uplink ports. Layer 2+ Management: Supports L2+ features including ACLs, VLAN (including voice VLAN, port‑based, protocol‑based, QinQ etc.), link aggregation, Spanning Tree Protocols (STP, RSTP, MSTP) etc.
Security: Multiple security features like ARP inspection, IP source guard, DoS protection, DHCP snooping, port security, MAC filtering, etc.
QoS / Traffic Prioritization: Priority mapping, queue scheduling (SP, WRR, Weighted etc.), rate limiting, traffic shaping. Auto‑detection and prioritization of latency‐sensitive traffic like voice, video, SIP/RTP etc.
VLAN & Multicast Support: Supports up to ~4,000 VLAN IDs, GVRP, IGMP snooping, MLD snooping, MVR. Virtually all features to segment traffic well.
Management / Monitoring: Web UI, SSH, Telnet, SNMP, RMON, LLDP / LLDP‑MED, syslog; cloud/on‑premises management via GWN.Cloud / GWN Manager etc.
Mounting / Deployment Flexibility: Can be mounted in rack, wall, or used on desktop; brackets included. Some models fanless; metal enclosure.
Here are detailed technical specs for GWN7802 (non‑PoE version unless otherwise stated), combined from multiple sources:
| Spec Category | Specification |
|---|---|
| Ports & Interfaces | 16 × 10/100/1000 Mbps RJ‑45 Ethernet ports 4 × Gigabit SFP ports 1 × Console port (RJ‑45 serial) Reset pinhole / button for factory reset |
| Switching Capacity / Performance | Non‑blocking throughput: ~20 Gbps Switching (backplane) capability: ~40 Gbps Forwarding rate: ~29.76 million packets per second (Mpps) Packet buffer: ~4.1 MB MAC address table size: ~8,000 entries |
| VLAN / Multicast / Aggregation | VLAN support: up to ~4,000 VLAN IDs; supports port‑based, protocol‑based, voice VLAN, QinQ etc. Link Aggregation: about 8 LAG groups for redundancy and load balancing. Spanning‑tree: STP, RSTP, MSTP; up to 64 instances in some specs. Multicast: IGMP v2/v3 snooping, MLD snooping, MVR support. |
| Security / Access Control | Quaternary binding (IP, MAC, VLAN & port) ARP inspection, IP source guard, DoS protection, DHCP snooping, port security, sticky MAC, MAC address filtering etc. |
| Quality of Service (QoS) & ACLs | Port priority, priority mapping, queue scheduling (strict priority, weighted round robin, etc.), traffic shaping, rate limiting; built‑in detection and prioritization of voice/video/SIP/RTP traffic. ACLs for IPv4 & IPv6. |
| Power / PoE | For non‑PoE model: No PoE on Ethernet ports. Integrated power supply (for switch itself) approx 30 W draw. For PoE model (GWN7802P): PoE/PoE+ support per port, dynamic allocation, but total powers and per‑port limits depend on variant. |
| Management & Monitoring | Web UI, SSH, Telnet, HTTPS; SNMP, RMON, LLDP/LLDP‑MED; syslog; diagnostic tools (ping, traceroute etc.) Cloud / On‑premises management: GWN.Cloud, GWN Manager, GDMS etc. |
| Physical / Mechanical / Environmental | Dimensions: approx 440 mm (L) × 200 mm (W) × 44 mm (H) Weight: about 3 kg Enclosure: metal, various mounting (desktop / wall / rack) with included brackets. Operating temperature: ~0°C to 45°C Storage temperature: −10°C to ~60°C Humidity: ~10%‑90% non‑condensing during operation; storage maybe broader. |
| Other | Warranty: ~3 years on many listings. LEDs: A system/status LED + per‑port LEDs for link/activity. Reset button/pinhole. |
