Grandstream GWN7832 Layer 3 Aggregation Switch, 12 x 10G SFP+

Overview

The Grandstream GWN7832 is an all-fibre switch that links fast access switches together over 10 Gbps, collecting the connections from floors or buildings and routing between them. Its twelve 10 Gbps SFP+ ports sit between the access switches and the core or router in a campus, hotel or multi-building network where every uplink runs at 10 Gbps.

Is it right for you?

• Suits a network where the access switches already have 10 Gbps uplinks and you want an aggregation layer to match.
• Choose it when you want routing between VLANs (virtual LANs) at the aggregation layer, with RIP, OSPF and BGP available.
• It has no copper ports and no PoE, so every connection needs a fibre module or DAC cable.
• For 1 Gbps fibre links, see the GWN7830 or GWN7831.

Key features

• Twelve 10 Gbps SFP+ ports; 240 Gbps switching capacity and 178.56 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; 12K IPv4 and 4K IPv6 routes.
• Stacking, so several units are managed from a single point.
• 4K VLANs, private VLAN, 32 link aggregation groups and 4K 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 60 W power supply plus an input for an optional external 12 V (60 W) redundant power supply (RPS); 440 x 200 x 44 mm, 2.67 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.
• 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.
• Only if you want backup power: an external 12 V (60 W) RPS.
• 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.
• There are no RJ45 ports on this model.
• Backup power needs the optional external 12 V (60 W) RPS.
• Rated for 0 to 45 °C.
