תאור:

Switch DGS-1210-52P / ME is the ideal solution for use in networks Metro Ethernet. This switch is equipped with 24 Gigabit Ethernet ports for connecting twisted pair, 24-port PoE and 4 SFP-port used for the organization to connect to high-speed line. Protection against static electricity ensures the stability of the surge voltage, and the full set of security and authentication protects the network from internal and external threats.
 
High performance
Switch DGS-1210-52P / ME is equipped with a 10/100 / 1000Base-T Ethernet, ensuring optimal network performance. This switch is equipped with SFP-ports and PoE, which allows to place networking devices, such as, IP-cameras PoE in locations where power outlets are not available. To do this, simply connect the device to the PoE Ethernet-cable that will transmit not only data but also power.
 
Resilience / performance
Switch DGS-1210-52P / ME supports protocols Spanning Tree (STP): 802.1D-2004 edition, 802.1w and 802.1s. STP allows you to organize data backup route used in the event of a malfunction of the switch. The switch also supports link aggregation 802.3ad, that interconnects a number of ports in the group and, as a consequence, increasing bandwidth and increasing resiliency of the compounds. DGS-1210-52P / ME support for IEEE 802.1p Quality of Service (QoS), which enables to classify traffic in real time to 8 queues with strict priority handling mechanisms and Weighted Round Robin (WRR). Packet classification is based on TOS, DSCP, MAC, IPv4, VLAN ID, port number, TCP / UDP, protocol type, or the contents of packages, user-defined, and provides a flexible adjustment for certain multimedia applications such as VoIP or IPTV.
 
Security and Authentication
Switch DGS-1210-52P / ME support access control 802.1X port-based / node, the possibility of creating a guest VLAN, and authentication and RADIUS / TACACS + for strict access control on the network. Function IP-MAC-Port Binding to D-Link switch allows you to control access to the network of computers based on their IP- and MAC-addresses as well as the connection port, thereby expanding possibilities of access control. Built-in D-Link Safeguard Engine ™ provides identification and prioritization of packets destined for processing by the processor switch, in order to prevent malicious attacks that could interfere with the normal operation of the switch. In addition, the Access Control List (ACL) improves network security and performance.
 
Management functions
The user-friendly Web-based interface for easy management and automatic configuration DHCP provides advanced management, enabling administrators to pre-configure the settings and save them to a TFTP-server. After that, the individual switches can receive IP-addresses from the server and load the preset configuration. Protocol LLDP (Link Layer Discovery Protocol) allows network equipment to notify local network of its existence and characteristics that help better manage the network topology. In addition, each port of the switch supports cable diagnostics to help identify the different faults, such as cable length discrepancy or its characteristics.
 
Traffic Control and Bandwidth
Bandwidth control allows network administrators to define bandwidth per port increments up to 64 kbit / s for incoming traffic. Switch DGS-1210-52P / ME also supports broadcast storm protection, which minimizes the likelihood of virus attacks on the network. Port Mirroring facilitate traffic diagnostics and helps administrators to monitor switch performance and alter it if necessary. Support for IGMP Snooping reduces the amount of multicast traffic and to optimize network performance.
 
Multicasting
Switch DGS-1210-52P / ME supports the full set of features for Layer 2 multicast, including IGMP Snooping, IGMP filtering, Fast Leave, and the setting for multicast traffic on specific ports. With the support of the functional switch DGS-1210-52P / ME allows working 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 the purpose of efficient spending of bandwidth transferred in a separate VLAN. ISM VLAN profiles allow users to quickly and easily assign / change the preset settings on ports multicast subscribers.
