Product Overview Technology Briefing • High Availability n ERPS (Ethernet Ring Protection Switching): ü Compare to RSTP, ERPS offers faster convergence capability which provides under 50 millisecond response. n Loopback Detection (LBD) ü Enable the shutdown of loop ports to prevent packet storm from overwhelming the whole network. n Authentication Database Failover ü Allows to configure the switch to check local database or bypass authentication when configured RADIUS server fails.

Product Overview n 802. 1 D-2004 RSTP & 802. 1 Q-2005 MSTP ü Enables redundant backup in case of link failure, enhancing network stability and resilience. n Support Microsoft Network Load Balancing (NLB) ü DGS-3120 supports load balancing network traffic across a number of servers which support Microsoft’s clustering technology. • Flexible Deployment Options That Fulfill Customer Needs n Enhanced Image (EI) ü Provides complete feature set for advanced operation. ü Includes IMPB, IPv 6, Static Route, ERPS, and s. Flow etc. n Standard Image (SI) ü Provides the essential security features and smart applications to fulfill business demand operation. ü Includes D-Link E 2 ES features; Qo. S, ACL, and Voice VLAN etc.

Product Overview • Comprehensive and Robust D-Link Endpoint Security n D-Link innovative IP-MAC-Port Binding (IMPB) ü Provides a strict access control for network resources. ü Prevents ARP spoofing and man-in-the-middle attacks. n Host-based Authentication / Authorization ü Brings the security down to an edge port level, enabling true privilege-based management of network services. ü Supported by 802. 1 X, Web-based Access Control (WAC) and MAC-based Access Control (MAC) n Compound Authentication ü Be able to enable 802. 1 X, WAC, MAC on the same port. ü Allows clients connected under the same port to use different authentication schemes ü Allows to enable IMPB along with 802. 1 X, WAC, or MAC for stricter access control n Identity-driven Security Policy Assignment ü Assigns ACL rules, VLAN, Qo. S policy based on each identity.

Product Overview • The Quality Assurance and Intelligent Vo. IP Solution 1 n DGS-3120 supports Voice VLAN and Advanced Qo. S features to simplify the Vo. IP usage. Switch automatically assigns IP Phones to Voice VLAN and provides a guaranteed quality. ü Voice VLAN: Automatically VLAN assignment for voice traffic determined by vendor MAC OUI. ü Advanced Qo. S: classify voice, data and multicast into different service levels. • Outstanding Energy Saving n DGS-3120’s Green technologies ü D-Link Green technologies: Power Saving by Link Status, and Power Saving by Cable Length 2 ü Time-based Po. E turns Po. E on or off based on a schedule to save power. When Po. E devices are not in use (i. e. during the night, or on the weekend) Po. E can be disabled until needed. ü Smart Fan: Fan speed will be adjusted by ambient temperature without full time 100% loading which saves power. ü The latest generation chipset offers lower power consumption.
