ZyXEL Communications, Inc. 24-port FE L3 Switch ES-4124

The Ideal Solution for a Convergent Network with the Highest Level of Flexibility, QoS and ProtectionIdeal for multi-service network environment The ZyXEL ES-4124 delivers fully dynamic wire-speed IP routing features like OSPFv2 and RIPv2 using a hardware-based IP routing engine, as well as sophisticated multilayer operating software that quickly and precisely transmits Layer-3 traffics without packet loss or latency. In addition to dynamic IP routing, the ZyXEL Switch 4000 Series supports DVMRP, IGMPv3 and MVR for most applications on today's IP-based multimedia platforms. With the ES-4124, enterprises can easily employ applications such as IP TV, video conferencing and distant learning. Intelligent QoS for mission-critical applications With more and more applications integrated into IP-based networks, the network traffic flows become more and more complicated and diverse than ever. To assure the multi-service quality on a converged network, adopting advanced traffic control technologies to manage different type of traffic flows is critical and necessary to enterprises. The ES-4124 supports Intelligent QoS features to optimize network traffics. With supports to Class of Service (CoS) and Differentiated Services Code Point (DSCP), administrator can easily classify and perform traffic prioritization for business-critical applications such as VoIP and video conferencing. In addition, the ES-4124 provides advanced bandwidth control with granularity of 64kbps and 8 hardware priority queues to bring better bandwidth administration to network operators. Comprehensive safety network Information Security is a critical issue in the era of information economy. In addition to preventing threats from the WAN, enterprises also need LAN security to protect intellectual properties. The ES-4124 provides a complete set of security features to protect important data, administrate traffic and secure the enterprise network. Through the multilayer (L2/L3/L4) ACL suite, the network administrator can easily check the source and destination information in MAC address, IP address, Ethernet type and TCP/UDP for security and QoS requirements. With 802.1x authentication and port security, administrators can reject unauthorized users from accessing the network. The intrusion lock function detects the "plugged" and "unplugged" status change of Ethernet cables, and the switch will deactivate the port automatically if necessary. Thanks for a complete set of security features; the ES-4124 is highly capable of protecting critical intellectual assets for enterprises. Robust and high-availability system design The ES-4124 supports the VRRP routing protocol for failover transmissions, while BPS, the second DC power source, protects the system from internal AC power supply failure. The IEEE802.3ad Link aggregation reduces network downtime by providing more packet paths and bandwidth aggregation to critical paths. The 4G uplink not only gives superb transmission bandwidth, but also allows users to set up Gigabit aggregation to secure transmission on critical paths, while the IEEE802.1w Rapid spanning tree (RSTP) allows immediate recovery from failed links by sending packets via a backup link path. Hassle-free network management and 24-unit stacking capability The ES-4124 provides various network management options. Networking administrators have the freedom to choose the friendly Web-based configuration or the convenient text-based CLI (Command Line Interface) to manage the switch. Since the ES-4124 supports centralized SNMP-based management software, maintenance can be performed remotely. The ES-4124 also supports the ZyXEL-exclusive iStacking clustering management technology that works across different floors and routing domains to locate other iStacking-capable switches in the same cluster, allowing administrators to manage up to 24 switches with one single IP. This greatly reduces operating costs and offers flexible maintenance to ZyXEL Switches.
