Product Description

This workgroup switch of the xStack series for Layer3 environments has 48x 10 / 100Mbit twisted pair ports. For connection to other switches, the DES-3852/E has 2 combo 1000Mbit twisted pair ports, which can optionally be converted into 1000Mbit fiber connections via additional mini GBIC SFP modules. Two additional gigabit copper ports are available on the rear for cascading the devices.

All four Gigabit copper combo ports can be connected to the backbone individually or as a trunk. Thanks to the favorable ratio of Gigabit Uplink bandwidth and a large number of Fast Ethernet connections, this Layer3 Virtual Stack Switch is ideal for workgroups or departments.

Reliable data transfer in time-critical applications is ensured by the possibility of bandwidth control. The data throughput can be defined for each individual port and, depending on the user, the network access can also be controlled separately. This prioritization ensures control of data transfer in the network, prevents unwanted data access and allows easy management of different applications; Including VoIP, web browsing, video and e-mail.

With the help of the implemented SIM protocol, the DES-3852/E can form virtual stacks with one another or with other SIM-capable devices using switches of the DES-3800 series. The supervision, Maintenance and configuration of the switches via a single IP address simplifies and speeds up recurring management tasks considerably. Network access

Advanced L3 Routing
The xStack DES-3852/E 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/E. These added routing features provide redundancy, improve network utilization, and provide load balancing for the network.

Metro Switching
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/E 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/E 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/E 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.

Network Security
The xStack DES-3852/E 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/E provides unparalleled security in its class. In addition, the xStack DES-3852/E 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/E incorporates IP-MAC-Port Binding and the D-Link Safeguard Engine to protect the CPU from broadcast, multicast, and unicast flooding.
