The DES-3200 switches is a line of managed switches D-Link 2-level, intended for networks Metro Ethernet (ETTX and FTTX) and corporate networks. Switches in this series are equipped with 8/16/24/48 port 10/100 Mbit / s Fast Ethernet, as well as combo port 1/2/4 Gigabit Ethernet / SFP. Switches DES-3200-10 / 18 made in the body width of 9.11 inches and are equipped with a passive cooling system, suitable for desktop use and for use in telecommunications and cabinets. Switches DES-3200-26,28,28 / ME, 28F, 52 1U height designed for installation in 19-inch rack and provides a connection to copper or optics (24/48 port) at a speed of 100 Mbit / c. All devices have a series of practical design with 1, 2 or 4 combo ports of Gigabit Ethernet / SFP, which provide bandwidth of up to 4 Gb / s and allow to use these switches in a ring topology. Switch DES-3200-28 / ME is made specifically for use in telecommunication closets, where operators and engineers have access only to the front of the device and need quick troubleshooting. All interfaces are located on the front of the DES-3200-28 / ME, including the connector for the power cable that meets the requirements of large networks. In addition, the switch DES-3200-28 / ME is equipped with a connector "dry contacts" for event detection and alarm. DES-3200-28F is the ideal solution for network deployment FTTX, allowing you to bring fiber optic line directly to the subscriber unit. Through the use of a switch DES-3200-28F fiber-optic communication lines to connect subscribers significantly increased transmission distance (up to 20 km) and excludes the impact of crosstalk inherent in copper. Switches DES-3200-28P / 52P meet the standards of PoE (Power over Ethernet-cable) IEEE 802.3af and IEEE 802.3at and provide power up to 15.4 watts per port and up to 30 watts on the first four / eight ports.Supports PoE / PoE + devices such as video / IP-phones, wireless access points and IP-cameras, lets you apply power to them directly from the switch to Ethernet-cable, which greatly simplifies network deployment. All switches DES-3200 series are equipped with 2 or 4 Gigabit ports SFP, which provides the ability to select the type of network topology, "ring", "tree" or mixed type.
Safety and reliability
Switches DES-3200 series supports access control based on 802.1x port / host, the ability to create a guest VLAN, and authentication and RADIUS / TACACS / XTACACS / TACACS + when connected to a switch. Function IP-MAC-Port Binding allows administrators to bind IP-address and MAC address of the user to a specific port number on the switch, thereby prohibiting the user to change the network settings. Moreover, thanks to the DHCP Snooping, the switch automatically detects pairs of IP / MAC-addresses issued by the server, DHCP-tracking packages and storing them in a "white list" IMPB. These features play a significant role in the support of network security. Built-in D-Link Safeguard Engine provides identification and prioritization of packets to be processed directly by the CPU switch to prevent malicious attacks and counteract the effects of parasitic traffic on the CPU switch. In addition, DES-3200 supports the list contains a complete access control (ACL). This functionality allows administrators to restrict access to network services and does not affect the performance of the switch.
Resilience / performance
Switches DES-3200 series supports the Protocol 802.1D-2004 edition, 802.1w and 802.1s Multiple Spanning Tree (MSTP). STP allows you to organize backup route data used in the event of any failed switch on the main route of the network traffic. The switches also support link aggregation, standards-based 802.3ad (LACP) and 802.1AX, allowing you to group multiple ports, increasing the bandwidth and increasing fault tolerance connections between network devices. The switches support 802.1p for Quality of Service (QoS). In addition, the traffic can be prioritized on the basis of marks TOS, DSCP, MAC-addresses or IP-address of the client, Vlan number, port number, TCP / UDP, protocol type, or based on the contents of packets specified by the user. This functionality is especially important in the provision of IPTV. Also DES-3200 series supports functional Voice VLAN, is a separate vlan, which is automatically placed in voice traffic, with a view to its subsequent processing with a higher priority level than the rest of the traffic.
Traffic Control and Bandwidth
With Bandwidth Control allows network administrators to define bandwidth for each port increments up to 8 kbit / s for incoming and outgoing traffic. The switches also support the functional protection from the storm (Storm Control), which allows you to get rid of unnecessary broadcast / multicast traffic. Port Mirroring facilitate traffic diagnostics and helps administrators to monitor network performance. Switches DES-3200 series supports markers "two-speed, three-colored marking" and "One speed, three color labeling" (trTCM / srTCM), allowing due to the decomposition of flows on the priorities to ensure maximum throughput of important traffic.
