24-Port Web Smart Switch III
24/48-Port Web Smart Switch III
D-Link’s DES-1210 Series is the latest generation of Web Smart Switches. Equipped with 24 or 48
10/100Mbps ports, 2 10/100/1000BASE-T ports, and 2 combo 10/100/1000BASE-T/SFP ports, the series integrates advanced management and security functions that provide performance and scalability. While easy to use, the DES-1210 Series provides a complete and affordable solution for small and medium businesses. Management options for the switches include SNMP, Web Management, SmartConsole Utility, and Compact Command Lines. The series also supports ACL filtering and D-Link’s Safeguard Engine. Furthermore, the DES-1210-28/52 uses Auto Voice VLAN, ensuring higher priority for voice traffic. Both models come with an innovative fanless design in 19”
metal cases.
Seamless Integration
The Web Smart Switches are designed to provide SMB users a complete control over the network.
With Ethernet and Gigabit copper ports capable of connecting to existing Cat.5 twisted-pair cables,
these switches eliminate the need for a complex reconfiguration process. The DES-1210 Series allows
for flexible connection to a backbone or servers. Additionally, all ports support auto-negotiation of
MDI/MDIX crossover, or configurable auto MDI and therefore do away with crossover cables or uplink
ports. This brings inexpensive and easy connectivity to your desktop.
Extensive Layer 2 Features
Equipped with a complete lineup of L2 features, these switches include IGMP Snooping, Port Mirroring,
Spanning Tree and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfer. At 2000Mbps Full Duplex, the Gigabit ports provide high-speed data pipes to servers with minimum data transfer loss. Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shut down the affected port. Cable
Diagnostics is designed for network administrators to quickly examine the quality of the copper cables and also determine the type of cable error.
QoS, Bandwidth Control
The switches are perfect for deployment in a VoIP environment, as they support Auto Voice VLAN and
Differentiated Services Code Point (DSCP) QoS for VoIP application. Auto Voice VLAN will automatically
place voice traffic from an IP phone to an assigned VLAN and by doing so enhance the VoIP service. With a higher priority and individual VLAN, this feature guarantees the quality and security of VoIP traffic. DSCP marks parts of an IP packet, enabling different levels of service to be assigned for network traffic. With Bandwidth Control, the network administrator can reserve bandwidth for important functions that require a larger bandwidth or might have high priority.
Secure your Network
D-Link’s innovative Safeguard Engine function protects the switches against traffic flooding caused
by virus attacks. The switches support 802.1X portbased authentication, allowing the network to be
authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature
enhances network security and helps to protect the internal IT network. With the IP-MAC-Port Binding
(DHCP Snooping) feature, the switch snoops DHCP information in order to automatically learn IP-MACPort Binding pairs and create a white list. Whenever cyber crime or hacking attempts are found, the IP change is kept under control and the location of the IP address becomes traceable. For added security, the DHCP Server Screening feature screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment.
Versatile Management
The new generation of Web Smart Switches provides growing businesses simple and easy management of their network using an intuitive SmartConsole utility or a web-based management interface that enables administrators to remotely control their network down to the port level. The SmartConsole easily allows customers to discover multiple D-Link Web Smart Switches within the same L2 network segment. With this utility, users do not need to change the IP address of their PC and it also provides an easy initial setting of the Smart Switches. Switches within the same L2 network segment that are connected to the user’s local PC are displayed on screen for instant access.
This allows extensive switch configuration settings and basic configuration of discovered devices such
as password changes and firmware upgrades. The DES-1210 Series also supports D-View 6.0 and
Compact Command Line Interface (CLI) through Telnet. D-View 6.0 is a Network Management
System that allows for the central management of critical network characteristics such as availability,
reliability, resilience, and security in a consistent way. D-View 6.0 provides a useful set of tools for network administrators who want to effectively manage device configurations, fault tolerance, performance, and security. CLI management of the switches is possible via Telnet. This makes the adjustment of basic settings like password changes or firmware and configuration file uploads possible.
