Premium Edge Switch for Service Provider and Enterprise Network
ZyXEL ES-3000 Series L2+ managed Ethernet Switch is designed for service providers and enterprise networks that demand the most stringent requirement over network resiliency, QoS and security protection. The ES-3000 Series offers premium features for excellent network performances and ensures network stability.

Robust and High- Availability System Design
The ES-3000 Series comes with comprehensive features to ensure round-the-clock operation of the network. With BPS support, power is supplied to the switch in case of an unexpected power outage. The IEEE802.3ad Link Aggregation feature reduces network downtime by providing redundant paths and bandwidth aggregation to critical connections. By utilizing unique design of 4G uplink, you own not only superb transmission bandwidth, but also extrasecured paths for critical transmission by aggregation of Gigabit ports. IEEE802.1w Rapid
Spanning Tree Protocol (RSTP) allows immediate recovery from failed links by sending packets via the backup link.

Intelligent QoS for Multi-Service Optimization
Harnessing new cost-cutting IP applications (such as VoIP and video conferencing) in today’s modern business environment makes a big difference in gaining the market advantage. The ES-3000 Series provides superior QoS capability to fully utilize the power of applications.
Features like multi-layer (L2/L3/L4) ACL, eight priority queues, DSCP and WFQ scheduling algorithm allow you to maximize network bandwidth usage and provide quality of network services. With the support of MVR and IGMP snooping features, the ES-3000 Series enables successful IP multicasting transmission across multi-VLAN environment. In addition, the ES-3000 Series supports flexible bandwidth control with granularity of 64kbps which enables better bandwidth administration for network operators.
