DGS-1210-28 Web Smart Switch

QoS, Bandwidth Control

The DGS-1210-28 supports Auto Surveillance VLAN (ASV), and Auto Voice

VLAN which are best suited for VoIP and video surveillance deployments. Auto

Surveillance VLAN is a new, industry-leading technology that the DGS-1210-28

Web Smart Switch provides. This technology consolidates data and surveillance

video transmission through a single DGS-1210-28, thus sparing businesses the

expense of dedicated hardware and facilities. ASV also ensures the quality

of real-time video for monitoring and control without compromising the

transmission of conventional network data. The Auto Voice VLAN technology

enhances the VoIP service by automatically placing voice trac from an IP

phone to an assigned VLAN. With higher priority and individual VLAN, these

features guarantee the quality and security of VoIP trac. Furthermore, the

DSCP markings on Ethernet packets enable dierent levels of service to be

assigned to network trac. As a result, these voice and video packets take

precedence over other packets. In addition, with Bandwidth Control, network

administrators 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 protects the switches against trac

ooding caused by virus attacks. The DGS-1210-28 supports 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 DGS-1210-28 includes ARP Spoong Prevention, which protects from

attacks on the Ethernet network that may allow an intruder to sni data

frames, modify trac, or bring trac to a halt altogether by sending fake ARP

messages to the network. To prevent ARP Spoong 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 DGS-1210-28 provides a D-Link Network Assistant Utility and a web-

based management interface that enables administrators to remotely control

their network down to the port level. The

D-Link Network Assistant Utility

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. It also simplies the initial setup of the

Web Smart Switches. Switches within the same L2 network segment that are

connected to the user’s PC are displayed on screen for instant access. This

allows extensive switch conguration and basic setup of discovered devices

including password changes and rmware upgrades. The DGS-1210-28 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. CLI management of the switches is possible via Telnet.

This makes it possible to adjust basic settings, passwords, conguration les,

and rmware with ease.

Seamless Integration

The DGS-1210-28 comes with Ethernet and Gigabit copper ports capable

of connecting to existing Cat5 twisted-pair cables. Additionally, with its

24 10/100/1000Mbps and 4 1G SFP ports, the DGS-1210-28 Web Smart Switch

can provide a more exible solution for upstream or downstream server

connections. At 2000 Mbps 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. The Cable

Diagnostic feature is designed primarily for administrators and customer

service representatives, and can help them rapidly discover the type of error

and determine the cable quality. Using the default presets, an administrator

can quickly set up the switch without reconguring any settings, helping to

ensure seamless integration into any network conguration.
