Product Description

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. 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. As a part of the ZyXEL One Network, the ZyXEL GS1920 Series utilizes the ZON utility and other inter-device features designed to reduce the time and effort necessary to set up a network. The GS1920 Series allows one-click remote management to detect ports that connect neighbouring devices while displaying IP information via a Web-based GUI. If a network-connected device like a Wi-Fi access point fails to operate properly, administrators can reset the device to default or power cycle the device from a switch in the Web-based GUI. Additionally, the GS1920 Series supports iStacking, which allow 1-IP management to configure, monitor and troubleshoot multiple switches.
