The xStack DES-3852 is a Layer 3 switch designed for working groups at large companies, as a backbone solution for smaller and medium-sized companies or as an access switch in broadband networks. The DES-3852 is equipped with 48 x 10/100Mbps Fast Ethernet ports and 2+2 Gigabit Ethernet ports, whereby two combo Gigabit Ethernet/Mini GBIC ports are positioned on the front and 2 pure Gigabit Ethernet ports are positioned on the back for dedicated trunking and stacking with other switches in combination with single IP management (SIM). The DES-3852 has advanced functionality such as wire-speed IP routing, OSPF, VRRP, Link aggregation (LACP), VLAN 802.1Q and prioritisation queues, enabling users to create a cost-efficient, well-functioning network with no bottlenecks. The DES-3852 also handles traffic intelligently, allowing the definition of priority queues 802.1p for streamed media, VoIP (Voice over IP) and other high-priority classes of traffic. The switch is also equipped with Quality of Service with IP TOS/DSCP for Layer 3 and TCP/UDP (also Payload - packet content) for Layer 4.
