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 ports 10/100 Mbit / s Fast Ethernet, and a combo port 1/2/4 Gigabit Ethernet / SFP. Switches DES-3200-10 / 18 made in the case of 9/11 inches wide and equipped with a passive cooling system, suitable for desktop use and for use in telecommunication and control cabinets. Switches DES-3200-26,28,28 / ME, 28F, 52 1U height designed for installation in 19-inch rack and provides a connection for 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-port combo Gigabit Ethernet / SFP, which provide bandwidth of up to 4 Gbit / 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 line directly to the subscriber unit. By using the switch DES-3200-28F fiber-optic lines to connect subscribers greatly increased transmission distance (20 km) and excludes the impact of crosstalk inherent in copper cable. 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, allowing them to supply power directly from a switch on the Ethernet-cable, which greatly simplifies network deployment. All switches DES-3200 series are equipped with 2 or 4 ports of Gigabit 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 802.1x port-based / 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-addresses and MAC addresses of the user to determine the 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 keeping the network secure. Built-in D-Link Safeguard Engine identifies and prioritization of packets to be processed directly by the CPU of the switch, in order to prevent malicious attacks and neutralize the effects of spurious traffic on the CPU switch. In addition, DES-3200 supports List for access control (ACL). This functionality enables administrators to restrict access to network services and does not affect the performance of the switch.
Resilience / performance
Switches DES-3200 series supports protocols 802.1D-2004 edition, 802.1w and 802.1s Multiple Spanning Tree (MSTP). STP allows you to organize data backup route used in the event of failure of any switch on the main route of the network traffic. The switches also support link aggregation, standards-based 802.3ad (LACP) and 802.1AX, which allows you to combine multiple ports into groups, increasing the bandwidth and increasing the resilience of 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 the package defined by the user. This functionality is especially important in the provision of IPTV. Also, The DES-3200 series supports the functionality of Voice VLAN, is a separate vlan, which is automatically placed in the voice traffic, with a view to its subsequent processing with a higher priority level than the rest of the traffic.
Traffic Control and Bandwidth
Bandwidth control allows network administrators to define bandwidth per 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 the network performance. Switches DES-3200 series supports markers "Two speed, three-colored marking" and "One speed three color labeling" (trTCM / srTCM), allowing flow splitting by prioritizing to ensure maximum throughput of important traffic.
Switches DES-3200 series supports a full feature set for L2 multicast, including IGMP Snooping, IGMP filtering, Fast Leave. With the support of the functional Switch The DES-3200 provides an opportunity to work with IPTV-services, enjoys a growing demand in the market.
IGMP / MLD Snooping allows host-based connection of multiple customer multicast group to a single network interface. When you use the ISM VLAN multicast traffic for efficient bandwidth consumption is transmitted in a separate Vlan. ISM VLAN profiles allow users to quickly and easily assign / change the preset settings on ports multicast subscribers.
Switches DES-3200 series supports a cable diagnostic function to check the status of network cables and identify the causes of malfunction of the cable. Function 802.1ag Connectivity Fault Management (CFM) provides tools for surveillance, as well as for troubleshooting in complex Ethernet-networks, allowing service providers to perform the test compound, and quickly locate network problems, identify users, faced with these problems. Options 802.3ah Ethernet OAM, Dying Gasp, and D-Link Unidirectional Link Detection (DULD) can improve network manageability and enhance stability of the compound, as well as to detect the fault.
Switches DES-3200 series supports standard management protocols such as SNMP, RMON, Telnet, SSH / SSL. The user-friendly web interface provides easy operation. Automatic, DHCP is an enhanced management feature that allows administrators to pre-configure the settings and save them to a TFTP-server and automatically applied to the switches in the process of obtaining IP-address from the server that makes network configuration easier and faster. Support of LLDP and LLDP-MED can detect used in an Ethernet network equipment. In accordance with the result of the search, the administrator can easily apply the settings to the device discovery and obtain a graphic representation of the topology using the Network Management System (NMS).
Function D-Link Single IP Management (SIM) simplifies and improves the efficiency of management tasks, allowing multiple switches simultaneously setting, surveillance and maintenance from any location using a Web-browser. Moreover, the switch 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 set of useful tools for effective configuration management, performance and security, as well as error detection.
Support for IPv6
Switches DES-3200 series has successfully passed the certification IPv6 Ready Logo Phase 2, which guarantees the operation of the switch in networks IPv6. In addition, this series supports both protocol stacks IPv4 / v6, allowing the switches to act as a bridge between IPv4 and IPv6. With the constant expansion of the network security problem is most acute. To solve 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.
