תאור:

The DES-3200 includes a line of managed switches D-Link 2-level series of xStack, designed for networks of Metro Ethernet (ETTX and FTTX) and corporate networks. Switches are equipped with 8/16/24/48 ports 10/100 Mbit / s Fast Ethernet, and 2/4 combo ports of Gigabit Ethernet / SFP. Switches are made in the case DES-3200-10/18 9 inches wide and equipped with a passive cooling system, suitable for desktop use, and for the installation of telecommunication and electrical cabinets. Switches DES-3200-26/28/52 1U height designed for installation in a 19-inch rack and provides connectivity to copper (24/48 ports), or in the case of the model DES-3200-28F, on the optics (24 ports) on rate of 100Mbit / c. The devices have a practical design with a 2 or 4 combo ports (depending on model), which provides bandwidth up to 4 Gb / s and allow to use these switches in a ring topology. Switch DES-3200-28/ME manufactured specifically for use in telecommunication closets, where the operators and engineers have access only to the front of the device and requires a quick troubleshooting. All interfaces are located on the front panel DES-3200-28/ME, including a connector for connecting the power cord that meets the requirements of large networks. In addition, the switch is equipped with a connector DES-3200-28/ME "dry contacts" for the detection of events and alarms. The DES-3200-28F is the ideal solution for the deployment of FTTX networks allowing you to bring fiber-optic lines directly to the subscriber device. Through the use of DES-3200-28F fiber-optic lines to connect subscribers significantly increases transmission distance (20 km) and excludes the impact of crosstalk inherent in copper cable. Switches DES-3200-28P/52P comply with PoE (Power over Ethernet supply cable) IEEE 802.3af, and provide power to 15.4 W per port, and 4/8 ports also support the standard IEEE 802.3at and allow you to connect devices with consumption power up to 30W per port. Support for the PoE / PoE + devices such as video / IP-phones, wireless access points and IP-cameras, allows the power to apply 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 ports, enabling you to select the type of network topology, "Ring", "tree" or mixed type.
 
Safety and smooth operation
Switch DES-3200 series supports access control based on the 802.1x port / host, guest VLAN, and authentication and RADIUS / TACACS / XTACACS / TACACS + to control access to most switch. The function IP-MAC-Port Binding provides a binding of IP-addresses and 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 detects a pair of IP / MAC-addresses issued by the server, the DHCP-tracking packets and storing them in a "white list" IMPB. These functions play an important role in supporting the safety net. Built-in D-Link Safeguard Engine provides identification and prioritization of packets to be processed directly by the processor switch to prevent malicious attacks and neutralize the effects of spurious traffic on the CPU switch. 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 switch performance.
 
Resilience / High Performance
Switch DES-3200 series supports 802.1D-2004 edition, 802.1w and 802.1s Multiple Spanning Tree (MSTP). STP is a backup route allow you to organize the data 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 allows the grouping of multiple ports, increasing the bandwidth and increasing the resilience of connections between network devices. Switches support 802.1p Quality of Service (QoS). In addition, the traffic can be prioritized on the basis of marks TOS, DSCP, MAC-addresses or IP-address of client numbers vlana, port, TCP / UDP, the protocol type, or on the basis of the contents of the package specified by the user. This functionality is especially important in the provision of IPTV. Also, a series of DES-3200 supports a functional Voice VLAN, representing a separate vlan, which is automatically placed voice traffic, with a view to its subsequent treatment with a higher priority than other traffic.
 
Traffic control and bandwidth
Bandwidth management feature allows network administrators to define the bandwidth for each port in increments of 82/64 kbit / s for outgoing and incoming 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 Traffic simplifies diagnosis, but also helps administrators to monitor network performance. Switch DES-3200 series supports markers "Two speed, three-colored markings" and "One speed, three-colored markings" (trTCM / srTCM), allowing flow through the partition on the priorities to ensure maximum throughput of important traffic.
 
Multicast
Switch DES-3200 series supports a full set of features for working with L2 multicast, including IGMP Snooping, IGMP filtering, Fast Leave. With 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 provides host-based connection of multiple clients multicast group to one network interface. When using the ISM VLAN multicast traffic to effectively spend the bandwidth is transmitted in a separate vlane. ISM VLAN profiles allow users to quickly and easily assign / change the preset settings on the ports subscribers multicast.
 
OAM
Switch DES-3200 series supports cable diagnostic function to check the status of network cables and identify causes of performance cable. Function 802.1ag Connectivity Fault Management (CFM) provides tools for surveillance and for troubleshooting in complex Ethernet-networks, allowing providers to check the connection and quickly locate network problems, identify users, faced with these problems. Functions 802.3ah Ethernet OAM, Dying Gasp, and D-Link Unidirectional Link Detection (DULD) can improve the manageability of the network and improve the stability of the compounds, as well as to detect a fault.
 
Management functions
Switch DES-3200 series supports standard management protocols such as SNMP, RMON, Telnet, SSH / SSL. The user-friendly web interface for easy management. DHCP automatically extended control is a function that allows administrators to pre-set settings and save them to a TFTP-server and is automatically applied to the switches in the process of IP-address from the server that makes network configuration easier and faster. Protocol support LLDP and LLDP-MED enables detection is used in an Ethernet network equipment. In accordance with the results of the search administrator can easily apply changes to the detected devices and a graphical 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 the simultaneous adjustment of several switches surveillance and maintenance from any workstation with Web-browser. Moreover, the switches DES-3200 series supports the software D-View 6.0. D-View 6.0 is a network management system, which can improve the most important for network performance characteristics such as performance, 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
Switch DES-3200 series has successfully passed the certification of IPv6 Ready Phase 2 Logo, which guarantees the work of the switch-based networks of IPv6. In addition, this series supports both protocol stacks IPv4/v6, allowing the switches to act as a bridge between the networks of IPv4 and IPv6. With continued expansion of the network security problem is most acute. To solve a series of DES-3200 supports features such as IPv6 ACL, IMPBv64 and L3 Control Packet Filtering4, designed to protect against network attacks in IPv6 networks.
