48-Port 10/100Mbps Switch + (2) Combo 1000BASE-T/SFP + (2) 1000BASE-T
Service provider networks are moving from circuit-based access to newer packet-based access that will require highly reliable intelligent switching, and at the same time demand 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.
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. Policy Based routing* (which forwards traffic based on L3/L4 SA/DA) and Multi-Path Routing* (which is the method of establishing multiple paths between given source- destination nodes within a network) are also features supported on the xStack DES-3852. These added routing features provide redundancy, improve network utilization, and provide load balancing for the network.
The DES-3852 incorporates an advanced portfolio of security features designed to protect your network from malicious attack. SSH & SSL encrypted management guarantee secure private configuration and monitoring when using the Graphical User Interface and Command Line. IP to MAC binding prevent unauthorized devices from accessing network resources. 802.1x port and MAC based authentication help provide added network security by requiring all users attempting to connect to your network, provide a username and password. This username and password must then be authenticated on a RADIUS or TACACS+ server thus insuring only authorized users have access to the network. Access control lists based on Layers 2/3/4, Rate Limiting, and Guest VLANs provide even more control over what and how users access the network. Finally with D-Link’s CPU Safeguard Engine, the DES-3852 is protected from Broadcast, Multicast, and Unicast flooding which in turn guarantees the DES-3852 is not crippled by DoS attacks.
