תאור:

DES-3200 switches included in the line of managed switches D-Link 2-tier series xStack, designed for networks of Metro Ethernet (ETTX and FTTX) and corporate networks. Switches are equipped with 8/16/24/48 port 10/100 Mbit / s Fast Ethernet, as well as 2/4 Combo Gigabit Ethernet / SFP with hardware revision A1 or 1-port 100/1000 SFP + 1 combo port Gigabit Ethernet / SFP / 2 x 100/1000 SFP + 2 combo port Gigabit Ethernet / SFP with hardware revision B1 and C1. Switches DES-3200-10/18 made in the body width of 9 inches and equipped with a passive cooling system suitable for desktop use and for use in telecommunications and cabinets. DES-3200-26/28/52 switches in a 1U height are designed for installation in 19-inch rack and provide connections for copper (24/48 ports) or, in the case of the model DES-3200-28F, on optics (24 ports) on speed of 100Mbit / c. The devices have a practical design with 1 or 2 or 4 combo ports (depending on the model and hardware revision), which provide bandwidth of up to 4 Gb / s and allow you to use these switches in a ring topology. The switch DES-3200-28/ME made specifically for use in telecommunication closets, where operators and engineers have access only to the front of the unit and need quick 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 the ideal solution for the deployment of FTTX networks allowing 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 (20 km) and excludes the impact of crosstalk inherent in copper cable. Switches DES-3200-28P/52P comply with PoE (Power over Ethernet cable) IEEE 802.3af power and provide up to 15.4 W per port, and 4/8 port also supports IEEE 802.3at standard and allow you to attach a device that consumed power up to 30 W per port. Support for PoE / PoE + devices such as video / IP-phones, wireless access points and IP-cameras, allows them to supply power directly from the switch on the Ethernet-cable, which greatly simplifies the deployment of the network. All switches DES-3200 series are equipped with 2 or 4 Gigabit SFP ports, which provides the ability to select the type of network topology, "ring", "tree", or mixed type.
 
Security and trouble-free operation
Switch DES-3200 series supports access control 802.1x port-based / host, the guest VLAN, and authentication and RADIUS / TACACS / XTACACS / TACACS + to control access to the switch itself. Function IP-MAC-Port Binding binds the IP-address and MAC address of the user to a specific port on the switch, thereby inhibiting the user to change network settings. Moreover, thanks to the DHCP Snooping, the switch automatically detects pairs of IP / MAC-addresses issued by the server, DHCP-tracking packets and saving them in a "white list" IMPB. These functions play an important role in supporting the security of the network. Built-in D-Link Safeguard Engine identifies and prioritization of packets to be processed directly by the CPU switch to prevent malicious attacks and counteract the effects of spurious traffic to the switch CPU. In addition, DES-3200 supports List for access control (ACL). This functionality allows administrators to restrict access to network services and does not affect the performance of the switch.
 
Resilience / High Performance
Switch DES-3200 series supports protocols 802.1D-2004 edition, 802.1w and 802.1s Multiple Spanning Tree (MSTP). STP protocols allow a redundant backup data path to be 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 enables you to group multiple ports, while increasing bandwidth and enhancing the resilience 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-addresses, or IP-address of the client, the rooms Vlana, 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. Also DES-3200 series supports functional Voice VLAN, representing a separate vlan, which is automatically placed in the voice traffic, with a view to its subsequent treatment with a higher priority than other traffic.
 
Traffic Control and Bandwidth
The function of bandwidth management allows network administrators to define throughput levels for each port in increments of 82/64 kbit / s for incoming and outgoing 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 facilitate traffic diagnostics and helps administrators to monitor network performance. Switch DES-3200 series supports markers "Two speeds, three color labeling" and "Single Speed, Three-color labeling" (trTCM / srTCM), allowing for the partition of streams prioritized to ensure maximum throughput of critical traffic.
 
Multicasting
Switch DES-3200 series supports a full set of features for working with 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, enjoys 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 traffic for the purpose of efficient expenditure of bandwidth is transmitted in a separate Vlan. ISM VLAN profiles allow users to quickly and easily assign / change the preset settings on ports multicast subscribers.
 
OAM
Switch DES-3200 series support the cable diagnostics to check the status of network cables and identify the reasons for failure of performance cable. Function 802.1ag Connectivity Fault Management (CFM) provides tools for surveillance, as well as for troubleshooting in complex and Ethernet-allowing service providers to validate the connection and quickly isolate network problems, identify the user when faced with these problems. Functions 802.3ah Ethernet OAM, Dying Gasp and D-Link Unidirectional Link Detection (DULD) can improve network manageability and increase the stability of the connection, as well as to detect the fault.
 
Management functions
Switch DES-3200 series 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 that 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 of the server that makes setting up a network easier and faster. Protocol support LLDP and LLDP-MED allows detection used in the Ethernet hardware. In accordance with the search result administrator can easily apply the settings to the detected devices, and a graphical image of the topology via the network management system (NMS).
Function 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 location using the 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, fault tolerance and security. D-View 6.0 provides network administrators with a useful set of tools to effectively manage the configuration, 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 operation of the switch in a network-based protocol IPv6. In addition, this series supports both protocol stack 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 it, 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.
