D-link xStack DGS-3120-24TC Switch

Standard and Enhanced Images:
- The DGS-3120 Series is embedded with two different software images - the Standard Image (SI) and Enhanced Image (EI). The Standard Image provides sophisticated features for campus or enterprise usage. The Enhanced Image supports all Standard Image features, in addition to advanced L3 features. With multiple software images, only the required features need to be purchased, providing a flexible approach to software licensing.

Enhanced Network Reliability:
- The DGS-3120 Series targets enterprises, campuses, and customers who require a high level of network security and maximum uptime. All the models in the DGS-3120 Series except the DGS-3120-24SC-DC support an external redundant power supply so that continued operation can be assured.

Comprehensive Security:
- The DGS-3120 Series provides users with the latest security features such as Multi-layer and Packet Content Access Control Lists (ACL), Storm Control, and IP-MAC-Port Binding (IMPB) with DHCP Snooping.

Identity Driven Network Policies:
- The DGS-3120 Series supports authentication mechanisms such as 802.1X, Web-based Access Control (WAC), and MAC-based Access Control (MAC) for strict access control and easy deployment.
