The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product code if the specifications are identical. We map away wrong codes or sometimes logistic variants.
Category :
A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resources with your entire home or office network.

Intelligent Multilayer Gigabit Ethernet Switch
ZyXEL GS-4000 Series is an intelligent Gigabit multilayer (L2/L3/L4) Ethernet switch that provides enterprise-class availability, resilient and redundant architecture with OSPF, VRRP, RSTP and port trunking. The GS-4000 Series offers many advanced features to make it the preferred choice for real-routing network in the enterprise. Advanced functionalities like QoS, rate-limiting, rule-based access control lists, multicasting support, wire-speed, high-performance IP routing and simplified management software (iStacking) highly improve network operation.

High-Performance Wire-speed Switching and IP Routing
The GS-4000 Series consists of two switches: the GS-4024 with 20-port 100/1000BASE-T RJ-45 and four dualpersonality GbE interface (RJ-45 or SFP), the GS-4012F with 8-port SFP open slots and four dual-personality GbE interface (RJ-45 or SFP). Base on non-blocking switching architecture, the GS-4000 Series can be deployed as both an intelligent access layer switch for enterprise wiring closets and as a Layer 3 backbone switch for SMB networks. The GS-4000 Series delivers wire-speed full-dynamic IP routing, like OSPF and RIP using a hardware-based IP routing engine and sophisticated multilayer operating software. In addition to dynamic IP multicast, the GS-4000 Series supports Distance Vector Multicast Routing Protocol (DVMRP) and Internet Group Management Protocol (IGMP) snooping to perfectly handle a variety of datagrams making the ZyXEL GS-4000 Series ideal for today’s multi-service network environment.

iFlow - Advanced QoS for Significant Service
The GS-4000 Series works with ZyXEL exclusive iFlow technology, a set of advanced QoS mechanisms, to insure noteworthy service, and smooth operation via a series of QoS processes to prevent customers’ networks being negatively impacted by network congestion. With intelligent multilayer capability, the GS-4000 Series offers wire-speed flow control which can classify, police, and prioritize the incoming packets according to predefined QoS policies. In classification, Differentiated Services Code Point field (DSCP) and the 802.1p class of service (CoS) field are identified to assess the priority of incoming packets. Classification and reclassification can be based on criteria as specific as rule-based on IP, MAC addresses, VLAN ID, TCP/UDP port number, on the other hand, for bandwidth management, the GS-4000 Series is loaded with powerful traffic management tools. For instance, the GS-4000 Series provides eight priority queues per port for different types of traffics, allowing administrators to set rule-based rate limiting which takes full advantage of limited network resources and guarantees the best performance.

iSafe - High-Security for Business-Critical Applications
The GS-4000 Series works with iSafe intelligent 3-tiers security which offers complete data security in the data and management plane via a wide range of security features to protect users’ data and administrative traffic, and secure the network from unauthorized users. 802.1x authentication and Port security provide the ability to deny unauthorized users from accessing the network. Limited MAC Number by Port limits the total number of devices connected to a switch port, therefore highly reducing the risk of unknown access from mass deployed wireless networks or Hubs. Cooperating with RADIUS, 802.1x is useful to prevent unauthorized access based on username and password (or other credentials) and acts as powerful access control for convergent networks with mixed wired and wireless access. The GS-4000 Series multilayer (L2/L3/L4) ACLs suite of sophisticated rule-based control mechanisms is easily deployed, based on realistic network environments via a Web GUI or command line to prevent abnormal and illegal access. The rules can be defined to deny packets based on source and destination MAC addresses, IP addresses, or TCP/UDP ports.

iManage - Enterprise-class Network Management
The GS-4000 Series works with iManage intelligent network management tool kits. Compared with conventional bounded network management, ZyXEL GS-4000 Series demonstrates its power with advanced management capabilities; such as ZyXEL-exclusive iStackingTM clustering management technology that can cross different floors and routing domains to locate other iStacking-capable switches in the same management cluster, thus allowing administrators to manage 24 switches with one single IP. This greatly reduces operating costs and offers more flexible maintenance of ZyXEL Switches. IT staff can opt for the Web or command line interface to suit their needs, and even encrypt their instructions with SSHv1/v2 and SSL/TLS. With these sophisticated functionalities, the IT staff is empowered to build a highly secure and efficient corporate network with minimum effort.
