The ES-2108 Managed Layer 2 Fast Ethernet Switch is specially designed for small workgroup environments. Its unique fan-less design eliminates annoying noise making it suitable for noise-intolerant environments. Based on non-blocking 1.6 Gbps switching architecture, the ES-2108 provides 8-port 10/100 Mbps Layer 2 switching capability at wire-speed over existing CAT-5 cabling to desktops. The Zy XEL ES-2108 series is designed to serve diverse applications in various network environments. For quality of service application, the ES-2108 series comes with 4 priority queues per port for different types of traffics. In addition, DSCP is supported as well to realize an end-to-end Qo S environment. Regarding IP multicasting applications, the ES-2108 series features IGMP snooping to optimize the service quality. Also in bandwidth management, the ES-2108 series can support bandwidth increment steps as low as 64 Kbps to fulfill demand requiring bandwidth differentiation. The Zy XEL ES-2108 series features VALN functions to secure your network: 802.1Q tagged VLAN & port-based VLAN. With 4K PVID, you get freedom in VLAN management. In addition, the support of MAC filtering, MAC freezing & Specific MAC forwarding, the ES-2108 series allows network administrators to set security policies based on device MAC addresses. Intrusion lock, a feature that disables a port when an Ethernet cable is disconnected, prevents intruders from accessing the network through the switch. Equipped with feature IEEE 802.1x authentications, it restricts unauthorized users from accessing your network & obtaining confidential data. Thus the ES-2108 series is designed to offer comprehensive security features for enforcing security policies on the network edge.
