DES-1210-28/ME Metro Ethernet switch has 24 ports of 10/100Base-TX, 2 SFP ports and 2 dual-personality ports (dual personality) 10/100/1000Base-T or SFP. Designed for deployment Metro Ethernet, this switch is made in a secure enclosure and supports a wide range of functions. 24-port 10/100Mbps equipped with built-in surge protection 6 kV, so that the device is protected from external damage during ignition wiring. The switch is equipped with 4-port SFP, which provides the ability to create the topology of the "double ring", and a wide range of opportunities to build networks, FTTx.
DES-1210-28/ME provides an opportunity to work with IPTV-services, enjoying a growing demand in the market, thanks to the support functions such as IGMP Snooping, Limited IP Multicast (Multicast Limit on IP-addresses), ISM VLAN and MLD Snooping. Limited IP Multicast feature allows you to specify profiles multicast and link them to the port or port range to permit or deny connection requests sent by users. Using the profile is much easier to manage if the user changes the package. When using the ISM VLAN (IGMP Snooping Multicast VLAN) multicast traffic to effectively spend the bandwidth is transmitted in a separate VLAN. MLD Snooping feature improves the efficiency of multicast, and can reduce costs during the transition to IPv6.
High performance and fault tolerance
Switch DES-1210-28/ME supports a wide range of functions, providing smooth operation and simplifying management. Using the protocol 802.1D STP, 802.1w RSTP and 802.1s MSTP eliminates loops and allows you to quickly organize data backup route in case of a primary connection. The switches also support link aggregation standards-based 802.3ad (LACP), which allows the grouping of multiple ports, increasing the bandwidth and increasing the resilience of connections between network devices. DES-1210-28/ME also supports QoS (Quality of Service). Packets can be classified based on the content and distribution of the queue. The mechanism of prioritization helps to differentiate traffic based on the requirements for quality of service.
DES-1210-28/ME also support functions to ensure the safe management of the device. SSH and SSL encrypt the HTTP and Telnet connection, so data can not be compromised at the time of transfer. 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. This feature helps service providers to prevent attacks Man-in-the-middle and ARP Spoofing. 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. The function DHCP Server Screening blocks the emergence of a network of unauthorized DHCP-server.
DES-1210-28/ME supports authentication based on 802.1x port / host authentication and RADIUS, TACACS +, Local. Administrators can also be placed by unauthorized users in the Guest VLAN and assign them limited access rights.
