The DES-3200 includes a line of managed switches D-Link 2-level, designed for networks of Metro Ethernet (ETTX and FTTX) and corporate networks. Switches in this series are equipped 8/16/24/48 10/100 Mbps Fast Ethernet and 1/2/4 combo ports Gigabit/SFP ports. The DES-3200-10/18 made in the body width of 9/11 inches and equipped with a passive cooling system, suitable for desktop use or for installation in telecommunication and distribution cabinets. The DES-3200-26,28,28/ME,28F,52 1U height designed for installation in 19-inch rack and provide connectivity via copper or optics (24/48 ports) at speeds of 100 Mbps. All series devices have a practical design with 1, 2 or 4 combo Gigabit Ethernet/SFP, which provide bandwidth up to 4 GB/s and allow to use these switches in a ring topology. The DES-3200-28/ME manufactured specifically for use in telecommunication closets, where operators and engineers have access only to the front of the device and required a quick search and Troubleshooting. All interfaces are located on the front panel DES-3200-28/ME, including a connector to connect the power supply cord that meets the requirements of large networks. In addition, the DES-3200-28/ME feature connector "dry contacts" for event detection and alarm actions. DES-3200-28F is the ideal solution for FTTX deployments, allowing you to bring fiber optic line directly to the subscriber's device. Through the use of a switch DES-3200-28F fiber-optic lines to connect subscribers significantly increases transmission distance data (up to 20 km) and excludes the impact of crosstalk inherent in copper cable. The DES-3200-28P/52P comply with PoE standards (power over Ethernet-cable) IEEE 802.3 af and IEEE 802.3 at and provide power up to 15.4 watts per port and 30 watts on the first four/eight ports. PoE/PoE+ devices such as video/IP phones, wireless access points and IP cameras, allows you apply power to them directly from the switch by Ethernet cables, which greatly simplifies network deployment. All switches DES-3200 series are equipped with 2 or 4 Gigabit SFP ports that provides the ability to select the type of network topology: ring, tree or mixed type. Safety and reliability Series switches DES-3200 series supports access control 802.1 x port-based/host, the ability to create a guest VLAN, and authentication to RADIUS/TACACS/XTACACS/TACACS+ when connecting to a switch. Function IP-MAC-Port Binding provides a binding of IP address and MAC address of the user to a specific port number on the switch, thereby prohibiting the user to change network settings. Furthermore with the DHCP Snooping feature, the switch automatically pairs the IP/MAC-addresses issued by the server, DHCP-tracking packets and saving them in the "white list" IMPB. These functions play an important role in supporting network security. Built-in function D-Link Safeguard Engine provides identification and prioritization of packets intended to be processed directly by the processor switch to prevent malicious attacks and counteract the effects of parasitic traffic on the CPU of the switch. In addition, the DES-3200 series supports access control lists (ACL). This functionality gives administrators the ability to restrict access to network services and has no impact on switch performance. Fault tolerance/high performance Series switches DES-3200 series supports 802.1 D-2004 edition, 802.1 w and 802.1 s Multiple Spanning Tree (MSTP). STP protocols allow you to organize backup route data used in the event of a malfunction of any switch on the primary route network traffic. The switches also support link aggregation standards-based 802.3 ad (LACP) and 802.1 AX, which enables you to group multiple ports, increasing bandwidth and redundancy for higher availability of the connections between network devices. The switches support 802.1 p 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, rooms VLAN, port number, TCP/UDP, Protocol type, or based on the contents of the package specified by the user. This functionality is particularly relevant in the provision of IPTV services. Also, a series of DES-3200 series supports functional Voice VLAN, representing a separate Wi-Fi, which is automatically placed voice traffic, with a view to its subsequent processing with a higher priority than other traffic. Traffic management and bandwidth The function of bandwidth management allows network administrators to define the throughput levels for each port with granularity down to 8 Kbps for upstream and downstream traffic. The switches also support functional protection from the storm (Storm Control), which allows you to get rid of unnecessary broadcast/ multicast traffic. Port mirroring eases traffic diagnostics and helps administrators to monitor network performance. Series switches DES-3200 series supports markers "Two speeds, Three color labeling" and "single speed, Three color labeling" (trTCM/srTCM), allowing due to splitting of flows according to priorities to ensure maximum throughput of important traffic. Multicast Series switches DES-3200 series supports a full set of functions for L2 multicast, including IGMP Snooping, IGMP filtering, Fast Leave. Thanks to the support of the functional switch DES-3200 provides an opportunity to work with IPTV-services, enjoying a growing demand in the market. IGMP/MLD Snooping host-based enables the connection of multiple clients multicast group to one network interface. When using the ISM VLAN multicast traffic for the purpose of efficient expenditure of bandwidth transferred to a separate plane. The ISM VLAN profiles allow users to quickly and easily assign/change the preset settings on ports multicast registration information to subscriber. OAM Series switches DES-3200 supports a cable diagnostic feature to check the status of network cables and pinpoint the cause of malfunction of the cable. Function 802.1 ag Connectivity Fault Management (CFM) provides tools for surveillance and for search and Troubleshooting in complex Ethernet-networks, allowing providers to validate the connection and quickly localize network problems, identifying the users affected by these problems. Functions 802.3 ah Ethernet OAM, Dying Gasp and D-Link Unidirectional Link Detection (DULD) can improve network manageability and increase the stability of the connection and detect faults. Management functions Series switches DES-3200 series supports standard management protocols such as SNMP, RMON, Telnet, SSH/SSL. User-friendly web interface and easy management. Automatic configuration DHCP is the function of the extended control, which allows administrators to pre-set configuration and save them to a TFTP-server and automatically apply to the switches in the process of obtaining an IP address from the server, which makes configuring your network easier and faster. Protocol support LLDP and LLDP-MED allows detection used in Ethernet network equipment. In accordance with the result of the search administrator can easily apply the settings to the detected devices and get a topology drawing through the network management system (NMS). The D-Link Single IP Management (SIM) simplifies and improves the efficiency of management tasks, providing the ability to simultaneously configure multiple switches, surveillance and maintenance from any workstation using a Web browser. Moreover, the series switches DES-3200 series supports software D-View 6.0. D-View 6.0 is a network management system that allows you to improve the most important for the network characteristics such as availability, reliability, fault tolerance and security. D-View 6.0 provides network administrators with a useful set of tools for efficient configuration management, performance, and security, as well as error detection. IPv6 Support Series switches DES-3200 series has been certified with IPv6 Ready Logo Phase 2 which guarantees the connectivity and manageability in an IPv6 network. In addition, this series supports both Protocol stacks IPv4/v6, allowing switches to act as a bridge between IPv4 and IPv6. With the constant expansion of the network security problem is most acute. For its solution a series of DES-3200 supports features such as IPv6 ACL, IMPBv6 and L3 Control Packet Filtering, designed to protect against network attacks in IPv6 networks.
