ccess 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. As a Layer 3 router, the switch supports standard IP routing (IPv4) for universal compatibility, as well as RIP-1, RIP-2 and OSPF. This means it is very easy to combine lots of different sub networks in the same switch. With Layer 2 and 3 support for each port, you will be able to customise your own filters based on MAC or IP addresses at the user computers, enabling unnecessary traffic to be filtered out and static routing tables to be created for specific destinations, for example. The DES-3852 has also been equipped with a number of security functions such as 802.1x port/MAC based RADIUS support, TACACS+, SSH v2, SSL v3 and ZoneDefense functionality for Proactive Network Security functionality, together with D-Link's new firewalls/IDSs, the DFL-800, DFL-1600, DFL-2500 and DFL-M510.
