[. . . ] Key Features L3 Advanced Routing Protocols, OSPF, VRRP Multilayer-aware (L2/L3/L4) ACL for Security Protection and Traffic Optimization IGMPv3, DVMRP, MVR Port Security and Enhanced 802. 1x Port Authentication VLAN Stacking (QinQ) for Network-based VPN or Campus VPN 802. 1x Authentication ZyXEL iStackingTM Technology Clustering Network Management SNMP & RMON Support IEEE 802. 1p 8 Hardware Priority Queue WFQ, WRR and SPQ Queuing Algorithms Backup Power System Support The ZyXEL Gigabit Switch 4500 Series consists of two switches: the ZyXEL XGS-4528F and XGS-4526. [. . . ] This unique benefit gives network designers the highest flexibility and cost advantage in terms of equipment investment, network administration and system maintenance. Intelligent QoS for Mission Critical Applications Ensure Best Network Status With more applications integrated into IP-based networks, traffic flows become more complicated and diverse than ever. To ensure the quality of multiple services on a converged network, adopting advanced traffic control technologies to manage different types of traffic flows is critical and necessary to enterprises. The ZyXEL 4500 Series supports Intelligent QoS features to regulate network traffics for the best Enterprise Switches ZyXEL Switch 4500 Series performance. Taking advantage of Class of Service (CoS) and Differentiated Services Code Point (DSCP) supports, administrators can easily classify and perform traffic prioritizing for critical business applications such as VoIP and video conferencing. In addition, the 4500 Series provides advanced bandwidth control with granularity of 64 kbps and 8 hardware priority queues that bring better bandwidth administration to network operators. Enterprise Switches ZyXEL Switch 4500 Series Robust and High-Availability System Design Guarantee Non-stop Operations The ZyXEL 4500 Series supports the VRRP routing protocol for failover transmissions. The second DC power source, called BPS, protects the device from internal AC power supply failures, while the IEEE 802. 3ad Link aggregation reduces network downtime by providing more packet paths and bandwidth aggregation to critical paths. The Gigabit connectivity not only gives superb transmission bandwidth, but also allows users to set up Gigabit aggregation for securing critical transmission paths. The IEEE 802. 1w Rapid spanning tree (RSTP) also allows immediate recovery from failed links by sending packets via a backup link path. Hassle-free Network Management and Stacking Capability of Up to 24 Units The ZyXEL 4500 Series provides various network management options for administrators to choose to manage the switch using friendly Web-based configuration or convenient text-based CLI (Command Line Interface), and it also supports SNMP-based, centralized management software for switch maintenance to be done remotely.
