DES-1210-28/ME
The DES-1210/ME series of switches is the ideal solution for use in Metro Ethernet networks. The devices of this series are equipped with 8/24 Fast Ethernet ports for copper connection, as well as 2/4 Gigabit/SFP combo ports, which provide bandwidth up to 4 Gbit/s and allow the use of these switches in a ring topology. Protection against static electricity of 6 kV provides resistance to power surges, and a full set of security and authentication functions protects the network from internal and external threats.
Security and authentication
DES-1210/ME series switches support port/host-based 802.1X access control, the ability to create a guest VLAN, as well as RADIUS/TACACS+ authentication for strict access control in the network. The IP-MAC-Port Binding function allows administrators to bind the source IP address to the corresponding MAC address for a specific switch port, contributing to the expansion of access control capabilities. The built-in D-Link Safeguard Engine™ function provides identification and prioritization of packets intended for processing by the switch processor in order to prevent malicious attacks that could interfere with the normal functioning of the switch. In addition, the Access Control Lists (ACLs) feature improves network security and performance.
Fault tolerance/High performance
DES-1210/ME series switches support Spanning Tree (STP) protocols: 802.1D-2004 edition, 802.1w and 802.1s. STP protocols allow you to organize a backup data transmission route used in the event of a malfunction of any switch on the main route of network traffic. The switches also support the aggregation of 802.3ad channels, which provides grouping of several ports and, as a result, increased bandwidth and increased fault tolerance of connections. These models support the 802.1p standard for quality of service management (QoS), which allows you to classify traffic in real time into 8 priority levels and 4 queues. Packet classification is based on TOS, DSCP, MAC, IPv4, VLAN ID, TCP/UDP port number, protocol type or packet content defined by the user, and provides flexible configuration for certain multimedia applications such as VoIP or IPTV.
Traffic and bandwidth management
The bandwidth management feature allows network administrators to determine the bandwidth for each port in increments of up to 64 Kbit/s for outgoing and incoming traffic. DES-1210/ME series switches also support broadcast storm management, which minimizes the likelihood of virus attacks on the network. The port mirroring feature simplifies traffic diagnostics, and also helps administrators monitor the performance of the switch and change it if necessary. Support for IGMP Snooping allows you to reduce the volume of multicast traffic and optimize network performance.
Multicast
DES-1210/ME series switches support a full set of Layer 2 functions for multicast, including IGMP Snooping, IGMP filtering, Fast Leave and configuration for multicast traffic on specific ports. Thanks to the support of this functionality, DES-1210/ME series switches provide the opportunity to work with IPTV services that are in growing demand in the market. IGMP/MLD Host-based Snooping enables multiple multicast group clients to connect to a single network interface. When using the ISM VLAN function, multicast traffic is transmitted in a separate VLAN in order to efficiently consume bandwidth. ISM VLAN profiles allow users to quickly and easily assign/replace preset settings on multicast subscriber ports.
Management functions
The user-friendly web interface provides ease of management, and automatic DHCP configuration provides advanced management functions, allowing administrators to set settings in advance and save them on the TFTP server. After that, individual switches can get IP addresses from the server and load predefined configuration parameters. The LLDP (Link Layer Discovery Protocol) protocol allows network equipment to notify the local network of its existence and characteristics, which helps to better manage the network topology. In addition, each port of these switches supports the cable diagnostics function, which helps to identify various malfunctions, for example, a mismatch in cable length or its characteristics.
