DES-1210-28EOL EOS
תאור
D-Links
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-Links 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-Links innovative Safeguard Engine function protects the switches
against traffic flooding caused by virus attacks. The switches also
support 802.1X port-based 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. The DES-1210 Series includes ARP
Spoofing Prevention, which protects from attacks on the Ethernet network
that may allow an intruder to sniff data frames on a LAN, modify
traffic, or bring traffic to a halt altogether by sending fake ARP
messages to the network. To prevent ARP Spoofing attacks, the switch
uses Packet Control ACLs to block invalid packets that contain fake ARP
messages. 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 users 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.
