Grandstream GWN7830 Layer 3 Aggregation Switch, 6 x SFP, 4 x 10G SFP+

Overview

The Grandstream GWN7830 is a compact fibre switch that links several access switches together, collecting the connections from wiring closets, floors or buildings and routing between them. It has six 1 Gbps SFP ports, four 10 Gbps SFP+ ports and two Gigabit RJ45 ports, and sits between the access switches and the core or router in a larger office, campus or hotel network.

Is it right for you?

• Suits a network with up to six access switches linked over 1 Gbps fibre and a few 10 Gbps links to the core.
• Choose it when you want routing between VLANs (virtual LANs) at the aggregation layer, with RIP, OSPF and BGP available.
• It has only two copper ports and no PoE, so it is not an access switch for desks, phones or cameras.
• For 24 fibre access links, see the GWN7831; for an all 10 Gbps aggregation layer, see the GWN7832.

Key features

• Six 1 Gbps SFP ports, four 10 Gbps SFP+ ports and two Gigabit RJ45 ports; 96 Gbps switching capacity and 71.424 Mpps forwarding rate.
• Layer 3 routing: static routes plus RIP (Routing Information Protocol), OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol), with RIPng and OSPFv3 for IPv6; 512 IPv4 and 128 IPv6 routes.
• Stacking, so several units are managed from a single point.
• 4K VLANs, private VLAN, 32 link aggregation groups and 2K ACLs (access control lists).
• ARP inspection, IP source guard, DoS protection, port security and DHCP snooping to keep unauthorised devices off the network.
• Built-in 30 W power supply; compact 330 x 175 x 44 mm case, 1.91 kg.

What else you need

• A mains socket: the power supply is built in.
• One fibre module or direct attach copper (DAC) cable per link, at each end. No transceivers are included.
• For the 1 Gbps SFP ports: Grandstream’s 1.25 Gbps modules F-MM850-550M-1.25G (multimode fibre, up to 550 m) and F-SM1310-20KM-1.25G (single-mode fibre, up to 20 km).
• SFP+ modules for the 10 Gbps uplinks: these are not included. Grandstream’s F-MM850-300M-10G (multimode fibre, up to 300 m) and F-SM1310-10KM-10G (single-mode fibre, up to 10 km) match the port speed.
• No extra software is needed for local management: the web UI and command-line interface (CLI, over console, Telnet or SSH) are built in. For central management use GDMS Networking (cloud), GWN Manager (on-premises) or a GWN series router.

Installation

A network installer or IT team should fit and configure it. It mounts on a desk, a wall or in a rack; the rack kit is included. Keep the room between 0 and 45 °C. Plan the fibre patching and keep unused connectors capped.

Software and licences

Management is through the local web UI, the CLI, SNMP v1/v2c/v3, GDMS Networking in the cloud, GWN Manager on your own server or a GWN series router. Local management works without an internet connection; GDMS Networking needs one.

Before you buy

• No transceivers are included; budget one module or DAC cable per link at each end.
• There is no PoE on the aggregation series.
• Rated for 0 to 45 °C.
