Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Ports : the number and type of ports (RJ45, SFP, PoE) differ between models of a single series, which nevertheless shares one photo.
  • Antennas : their number, gain and whether they can be removed depend on the reference.
  • Modules and cables : SFP modules, transceivers, DAC cables, PoE injectors and rack-mounting kits are not included unless stated.
  • Power : some equipment is powered over PoE and shipped without a power adapter.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

Product overview

Grandstream GWN7830 Layer 3 aggregation switch: 4 SFP+ 10 Gbps ports, 6 Gigabit SFP ports and 2 Gigabit RJ45 ports to aggregate and route traffic from multiple access switches across medium to large-scale networks.
Ports: the 4 SFP+ 10 Gbps ports (fibre or DAC cable) handle very high-speed uplinks, while the 6 Gigabit SFP ports and 2 Gigabit RJ45 ports round out connectivity for long-distance fibre links or servers.
L3 management: static and dynamic routing (RIP, OSPF, OSPFv3), 4K VLANs, QoS, IGMP/MLD Snooping, managed via GWN.Cloud, GWN Manager or the local web interface.
Also: 96 Gbps switching capacity, 71.424 Mpps forwarding rate, 16K MAC table, 6 link aggregation groups, STP/RSTP/MSTP, 6 kV surge protection, rack-mountable chassis measuring 330 x 175 x 44 mm.

Frequently asked questions about this product

What connectivity does the Grandstream GWN7830 offer?
4 × 10 Gbps SFP+ ports, 6 Gigabit SFP slots and 2 Gigabit RJ45 ports. It is an aggregation switch: it brings together the uplinks of several access switches, rather than connecting workstations directly.
Does the GWN7830 route between VLANs?
Yes, it is a Layer 3 switch. It handles static routing and dynamic routing via RIP, RIPng, OSPF and OSPFv3, over both IPv4 and IPv6, with VLAN virtual interfaces. A separate router is therefore not needed between your internal networks.
How many VLANs can be created on this switch?
Up to 4,000 VLANs, port-based or 802.1Q-tagged, with a dedicated voice VLAN for IP telephony. The MAC address table holds 16,000 entries, whether static, dynamic or filtering.
How many links can be aggregated on the GWN7830?
Six link aggregation groups, to widen an uplink and make it resilient to a cable failure. STP, RSTP and MSTP spanning tree is supported across 32 instances, so VLANs can be spread over separate paths.
What protection against attacks does this switch provide?
ARP inspection, IP Source Guard, DHCP snooping, denial-of-service attack protection, port isolation and port security with sticky MAC, storm control and BPDU loop protection. Access control lists support up to 2,000 rules, for Ethernet, IPv4 and IPv6.
How are devices authenticated on the GWN7830?
With 802.1X, using a RADIUS or TACACS+ server. Administrative access itself is tiered by accounts and passwords, over HTTPS, SSH or Telnet, and a Kensington slot physically locks the unit.
How does quality of service prioritise traffic?
Through port priority, priority mapping and queue scheduling — SP, WRR, WFQ, SP-WRR and SP-WFQ — backed by traffic shaping and rate limiting. IGMP and MLD snooping also prevent the network from being flooded with multicast streams.
What performance does the GWN7830 claim?
96 Gbps switching capacity and 71.424 Mpps, including 48 Gbps of non-blocking throughput, with latency under 4 microseconds. The switch can therefore handle several 10 Gbps links at once without becoming the bottleneck.
Is the switch managed from the cloud or locally?
Both. A controller is built into the switch's web interface at no extra cost, and a command-line interface is available. GWN.Cloud manages your devices from the cloud, and GWN Manager from a server installed on your own network.
What can be plugged into the 10 Gbps SFP+ ports?
Optical modules or direct attach cables (DAC) up to 5 m. A DAC cable costs less than a pair of modules for linking two neighbouring racks; beyond that, fibre with its modules is the way to go. Neither modules nor cables are included with the switch.
Is the GWN7830 protected against power surges?
Yes, built-in surge protection is provided, rated up to 6 kV. It protects the switch and connected equipment during abnormal electrical events, which matters on copper links between buildings.
Where can this aggregation switch be installed?
In a 19-inch rack, on a wall or on a desk, with the mounting kits included. The unit measures 330 × 175 × 44 mm, i.e. 1U high and less than 18 cm deep: it fits in a wall-mounted cabinet.
Is the switch new and covered by a warranty?
Yes, new equipment, with the invoice serving as the warranty document. Full details of its features are in the GWN7830 series documentation. None of its ports supply PoE.
