ZyXEL Smart Switch Simplifies Robust Network Management
Today’s small and medium-sized businesses (SMBs) expect a higher level of performance from their networks—more connections to support diverse applications, fewer network disruptions, easier management and a greater degree of network security. The ZyXEL GS1920 Series of switches fulfills these expectations with support for 24/48 100/1000BASE-T PoE Plus or non-PoE copper ports, as well as non-blocking performance and high-power budget support to facilitate a greater number of network connections.

The ZyXEL GS1920 Series offers network protection features and comprehensive access management functions to establish a reliable and secure network environment. Easy deployment, smart management and solid security—the GS1920 Series is the best solution for SMB networks.

Robust network availability
Network disruptions are a frequent source of headaches for small to medium-sized businesses. Whether outages are caused by internal errors or outside attack, the ZyXEL GS1920 Series protects users from network disruptions and ensures uninterrupted connectivity through several key features. Loop Guard helps networks avoid service disruptions caused by switching loops, and IP Source Guard (IPSG) shields your network from MAC spoof and ARP spoof attacks. Additionally, attacks such as BPDU, ARP and IGMP can target network facilities. However, CPU protection guarantees that a network continues to operate, even while under attack. Furthermore, dual firmware image and configuration features improve network reliability and availability. These are just some of the ways the GS1920 Series switches guarantee headache-free network connectivity for SMBs.

Rigorous access protection to secure the network
The ZyXEL GS1920 Series provides efficient allocation of network resources while ensuring comprehensive access protection, along with simple and secure network control. Intrusion Lock detects connection status and ensures port security. Not only does the GS1920 Series support 802.1X authentication with RADIUS, but it can monitor, filter and police all traffic between clients within the same subnet, creating an even higher degree of security.

Simplified management and future-proof your investment
There’s no need to learn a new command line interface. The ZyXEL GS1920 Series simplifies network management with a user-friendly web management interface. Additionally, full IPv6 support with features including auto configuration, duplicate address prevention, dual-stack and neighbor discovery, the ZyXEL GS1920 Series can easily migrate to the next-generation Internet Protocol in the future to ensure your investment is protected.
