28-port Gigabit WebManaged switch: 24x Gigabit metal + 4x Gigabit combo (metal/SFP), IPv6, 802.3az (Green), Layer 2-4 security options, L2 Multicast, fanless, 19" rackmount.Smart managed switch with essential L2 features.GbE RJ-45, GbE combo (RJ-45/SFP) and fixed GbE SFP connectivity.Reliable network availability with Loop Guard, IPSG, and CPU protection.Intrusion lock, RADIUS, static MAC forwarding and 802.1X authentication-enhance network security.Future-proofed with IPv6 support.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.Advanced standard compliance with intelligent power function support.ZyXEL GS1920 Series PoE switches support 802.3at PoE Plus standards, with a 375-watt high-power budget to meet the connectivity needs of additional powered devices like 802.11ac WLAN access points, VoIP phones and IP cameras. Not only do the GS1920 Series switch PoE models feature full PoE ports, they also employ intelligent technology. While set to Consumption Mode, switches can automatically detect the power consumption status of each powered device and supply only the amount of power required. This intelligent power allocation function minimizes wasteful overpowering of devices, thereby helping businesses save money, while enabling the PoE switch to power more devices.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.Standard Compliance.IEEE 802.3 10BASE-T Ethernet.IEEE 802.3u 100BASE-TX Ethernet.IEEE 802.3ab 1000BASE-T Ethernet.IEEE 802.3z 1000BASE-X.IEEE 802.3az EEE.IEEE 802.3x flow control.IEEE 802.3ad LACP aggregation.IEEE 802.1AB LLDP/LLDP-MED.IEEE 802.1D Spanning Tree Protocol (STP).IEEE 802.1w Rapid Spanning Tree Protocol (RSTP).IEEE 802.1s Multiple Spanning Tree Protocol (MSTP).IEEE 802.1Q VLAN Tagging.IEEE 802.1p Class of Service (CoS) Prioritization.IEEE 802.1X port authentication.Resilience and Availability.IEEE 802.1D Spanning Tree Protocol (STP).IEEE 802.1w Rapid Spanning Tree Protocol (RSTP).IEEE 802.1s Multiple Spanning Tree Protocol (MSTP).IEEE 802.3ad LACP (Max # Trunks/Links per Trunk): 8/8.Loop guard.ErrDisable recovery.MRSTP (ZyXEL proprietary).Dual configuration files.Dual images.Traffic Control.802.1Q Static VLANs/Dynamic VLANs: 1 K/4 K.Port-based VLAN.Protocol-based VLAN.IP Subnet-based VLAN.MAC-based VLAN.Private VLAN.Voice VLAN.VLAN ingress filtering.LACP algorithm of source/destination MAC/IP.GVRP.L2PT.Security.802.1X.Port security.Layer 2 MAC filtering.Layer 3 IP filtering.Layer 4 TCP/UDP socket filtering.Static MAC forwarding.Multiple RADIUS servers.Multiple TACACS+ servers.802.1x VLAN and 802.1p assignment by RADIUS.Login authentication by RADIUS.Login authentication by TACACS+.TACACS+ accounting.Authorization on RADIUS.Authorization on TACACS+.SSH v1/v2.SSL.Intrusion lock.MAC freeze.DHCP snooping.ARP inspection.Static IP-MAC-Port binding.Policy-based security filtering.Port isolation.IP source guard.Limit number of MAC per VLAN.MAC search.Guest VLAN.ACL packet filtering (IPv4/IPv6).CPU protection.Interface related trap enable/disable (by port).Quality of Service (QoS).No. of hardware queues per port: 8.802.1p queuing methods: SPQ, WRR, WFQ.Storm control: broadcast, multicast, unknown unicast (DLF).Port-based rate limiting (ingress/egress).Rate limiting per IP/TCP/UDP per port.Policy-based rate limiting.802.3x flow control.802.1p Class of Service (SPQ, WFQ, SPQ/WFQ combination capable).DiffServ (DSCP).Layer 2 Multicast.L2 multicast.IGMP snooping (v1, v2, v3).IGMP snooping Fast Leave.Configurable IGMP snooping timer and priority.IGMP snooping statistics.IGMP throttling.MVR support.IGMP filtering.IGMP snooping immediate leave.IGMP proxy mode & snooping mode selection.MLD snooping.Manageability.SNMP v1, v2c, v3.SNMP trap group.RMON (1, 2, 3, 9).ICMP echo/echo reply.Syslog.IEEE 802.1AB LLDP.IEEE 802.1AB LLDP-MED.IPv6 Management.IPv6 over Ethernet (RFC 2464).IPv6 addressing architecture (RFC 4291).Dual stack (RFC 4213).ICMPv6 (RFC 4443).Path MTU (RFC 1981).Minimum path MT.
