For the SMB requiring a cost effective core switching solution, as well as for larger Enterprise and Metropolitan Service Provider (MSP) environments needing a managed, feature rich switch capable of uplinking to backbone switches, the D-Link xStack DES-3852 is designed to meet the needs of the most demanding departmental and enterprise connectivity applications. The xStack DES-3852 Switch is a fully managed Layer 3 switch that provides 24 10/100Mbps Fast Ethernet ports and 2 Combo SFP/1000BASE-T Gigabit Ethernet ports. In addition, 2 fixed 1000BASE-T ports in the back-panel can provide a dedicated trunk connection between devices or core switches. The xStack DES-3852 also provides virtual stacking functionality via D-Link Single IP Management (SIM) technology allowing up to 32 units to be managed via a single IP address. With support for Q-in-Q Double VLAN tagging, IPv6 awareness*, Dynamic Layer 3 Routing, IEEE 802.1s, and bandwidth control, the xStack DES-3852 incorporates advanced features suitable for the MSP as well as the SMB and Enterprise size network.

Advanced L3 Routing
The xStack DES-3852 is a high performance Layer 3 switch that provides an ideal solution by offering advanced Layer 3 routing features such as RIP, OSPF, VRRP, up to 10 IP addresses per VLAN, and floating static routes. Multi-path Routing*, which is the method of establishing multiple paths between given source-destination nodes within a network, is also a feature supported on the xStack DES-3852. These added routing features provide redundancy, improve network utilization, and provide load balancing for the network.

Service provider networks are moving from circuit-based access to newer packet-based access that requires highly reliable intelligent switching and demands resiliency and dependability. The xStack DES-3852 meets this demand by supporting industry standards for 802.1s (Multiple Spanning Tree), 802.3ad link aggregation for up to 32 groups, bandwidth rate limiting down to 64k, and support for an external redundant power option for added peace of mind. In addition, the xStack DES-3852 offers Double VLAN Q-in-Q tagging, which adds on an additional tag to a VLAN tag, expanding the VLAN space and allowing service providers to deploy their service quickly and securely. The xStack DES-3852 also incorporates advanced QoS support such as the ability to filter and forward traffic based on Layer 2/3/4, making it an ideal choice for VoIP, video, and audio services targeting business class customers.
The xStack DES-3852 is equipped to handle many of today’s emerging security vulnerabilities. Up to 800 independent access control lists can be configured with the ability to filter and block traffic based on such criteria as: Port, MAC, 802.1p priority, VLAN, DSCP, IP address, Protocol type, and TCP/UDP port number and content, proving that the xStack DES-3852 provides unparalleled security in its class. In addition, the xStack DES-3852 incorporates 802.1x Port-based and MAC-based RADIUS authentication for secure network logins and SSH/SSL for increased management security. Further, the xStack DES-3852 incorporates IP-MAC-Port Binding and the D-Link Safeguard Engine to protect the CPU from broadcast, multicast, and unicast flooding.
