DES-3200 switches are in the line of managed switches D-Link Layer 2, designed for network 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 1/2/4 Combo Gigabit Ethernet / SFP. Switches DES-3200-10/18 connections in width 9/11 inches and come with a passive cooling system, suitable for desktop use, and for use in telecommunication and electrical cabinets. The DES-3200-26, 28,28 / ME, 28F, 52 in 1U height designed for installation in 19-inch rack and provide connectivity over copper or optical (24/48 ports) at 100 Mbits / c. Each series have a practical design with 1, 2 or 4 Combo Gigabit Ethernet / SFP, which provide a bandwidth of up to 4 Gb / s, and you can use these switches in a ring topology. Switch DES-3200-28/ME manufactured specifically for use in the telecommunications closet, where operators and engineers have access only to the front of the unit and needs fast troubleshooting. All interfaces are located on the front panel DES-3200-28/ME, including a connector for the power cable that meets the requirements of large networks. In addition, the switch has a connector DES-3200-28/ME "dry contacts" for event detection and alarm. DES-3200-28F is ideal for deployments FTTX, allowing you to bring fiber optic line directly to the subscriber's device. Through the use of the DES-3200-28F fiber-optic lines to connect subscribers significantly increases transmission distance (20 km) and excludes the impact of crosstalk inherent in copper. DES-3200-28P/52P switches comply with the standards PoE (power supply for Ethernet-cable) IEEE 802.3af and IEEE 802.3at and provide power up to 15.4 watts per port and up to 30 W in the first four / eight ports. Support for the PoE / PoE + devices such as video / IP-phones, wireless access points and IP-camera, you can bring power to them directly from the switch to Ethernet-cable, which greatly simplifies the deployment of the network. All switches DES-3200 series are equipped with 2 or 4 Gigabit SFP, enabling you to select the type of network topology, "ring", "tree", or mixed type.
Safety and reliability
The DES-3200 supports 802.1x access control based on the port / host, to create a guest VLAN, and authentication of RADIUS / TACACS / XTACACS / TACACS + to connect to the switch. Function of IP-MAC-Port Binding binds the IP-address and the MAC address of the user to a specific port on the switch, thus inhibiting the user to change network settings. Moreover, thanks to the DHCP Snooping, the switch automatically determines the pair IP / MAC-address issued server, DHCP-tracking packages and keeping them in the "white list" IMPB. These functions play an important role in supporting the security of the network. Built-in D-Link Safeguard Engine provides identification and prioritization of packets to be processed directly by the processor switch, in order to prevent malicious attacks and neutralize the effects of the parasitic traffic to the switch CPU. In addition, DES-3200 supports the Access Control List for (ACL). This functionality allows administrators to restrict access to network services and does not affect the performance of the switch.
Resilience / performance
The DES-3200 supports 802.1D-2004 edition, 802.1w and 802.1s Multiple Spanning Tree (MSTP). STP protocols allow a redundant backup data path used in the event of a 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 enables you to group multiple ports, increasing the bandwidth and increasing the resiliency of connections between network devices. The switches support IEEE 802.1p Quality of Service (QoS). In addition, the traffic can be prioritized on the basis of marks TOS, DSCP, MAC-address or IP-address of the client, number vlan, port, TCP / UDP, protocol type, or based on the contents of the package specified by the user. This functionality is especially important in the provision of IPTV. A series of DES-3200 supports functional Voice VLAN, is a separate vlan, which is automatically placed voice traffic, with a view to its subsequent treatment with a higher priority than other traffic.
Traffic management and bandwidth
Bandwidth management feature allows network administrators to define throughput levels 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 excessive broadcast / multicast traffic. Port Mirroring easier to diagnose traffic, and helps administrators to monitor network performance. The DES-3200 support tokens "Two speeds, three color marking" and "Single Speed, Three color marking" (trTCM / srTCM), allowing for the partition of flow prioritized to ensure maximum throughput of critical traffic.
The DES-3200 supports a complete set of features for working with L2 multicast, including IGMP Snooping, IGMP filtering, Fast Leave. With the support of this functional switch DES-3200 provides the opportunity to work with IPTV-service, enjoying a growing demand in the market.
IGMP / MLD Snooping allows host-based connection of multiple clients multicast group to a single network interface. When using the ISM VLAN multicast 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.
The DES-3200 support the cable diagnostics to check the status of network cables and determine the cause of failure of performance cable. Function 802.1ag Connectivity Fault Management (CFM) provides tools for surveillance, and for troubleshooting in complex Ethernet-networks, allowing service providers to validate the connection and quickly pinpoint network problems, identify the users, faced with these problems. Functions 802.3ah Ethernet OAM, Dying Gasp, and D-Link Unidirectional Link Detection (DULD) can improve network manageability and improve connection stability, and detect malfunctions.
The DES-3200 supports standard management protocols such as SNMP, RMON, Telnet, SSH / SSL. The user-friendly web interface and easy management. DHCP automatically is an enhanced management, which allows administrators to pre-configure the settings and save them to the TFTP-server and automatically apply to the switches in the process of obtaining IP-address from the server, which makes the network setup easier and faster. Protocol support LLDP and LLDP-MED can detect network uses Ethernet equipment. In accordance with the result of the search administrator can easily apply the settings to find your device and get a graphical representation of the topology with network management systems (NMS).
Function D-Link Single IP Management (SIM) simplifies and improves the efficiency of management tasks, allowing multiple simultaneous configuration switches, surveillance and maintenance from any location via Web-browser. Moreover, the switch DES-3200 series supports software D-View 6.0. D-View 6.0 is a network management system that helps to improve the most important for the network characteristics such as availability, reliability, resilience and security. D-View 6.0 provides network administrators with a useful set of tools to effectively manage the configuration, performance, security, and error detection.
Support for IPv6
The DES-3200 has successfully passed the certification of IPv6 Ready Logo Phase 2, which guarantees the operation of the switch in networks IPv6. In addition, this series supports both protocol stack IPv4/v6, allowing switches to act as a bridge between the networks of IPv4 and IPv6. With constant expansion of the network security problem is most acute. To solve it, the DES-3200 series supports features such as IPv6 ACL, IMPBv6 and L3 Control Packet Filtering, designed to protect against network attacks in IPv6 networks.
