DGS-1210-28P

The DGS-1210-28P customizable L2 switch with 24 10/100/1000Base-T PoE ports and 4 100/1000Base-T/SFP combo ports supports D-Link Green technology and advanced management and security features for high performance and network scalability. Management features include SNMP, Web-based management, the D-Link Network Assistant utility, and a simplified command line interface (CLI) via Telnet. DGS-1210-28P supports Auto Voice VLAN, providing maximum priority for "voice" traffic. This model is equipped with intelligent fans, which can change the speed of rotation depending on the temperature, which saves energy and reduces noise.

Power over Ethernet
The 24 ports on this switch support the IEEE 802.3at PoE standard. Each PoE port supplies power up to 30 watts for a total switch budget of 193 watts, allowing users to connect devices compatible with the 802.3at standard to the DGS-1210-28P. This allows equipment to be placed in hard-to-reach locations regardless of the location of electrical outlets and minimize cabling. In addition, the DGS-1210-28P supports Perpetual PoE, which keeps power in line during a "warm reboot".

Power saving
Thanks to D-Link Green technology, the DGS-1210-28P switch saves power without compromising performance or features. The switch detects the connection status of each port and automatically switches inactive ports to sleep mode. The DGS-1210-28P has a chipset which can significantly reduce your power consumption.

Layer 2 Features
The DGS-1210-28P switch supports a full set of Layer 2 features, including IGMP Snooping, Port Mirroring, Spanning Tree Protocol (STP), and Link Aggregation Control Protocol (LACP). IEEE 802.3x flow control allows you to optimize the switch's workload to improve data reliability. Supporting speeds of up to 2000Mbps on each port in full-duplex mode, the switch provides the high performance needed to connect your workstations. The switch supports cable diagnostics and Loopback Detection. Loopback Detection is used to detect loops and automatically shuts down the port where a loop is detected. The Cable Diagnostics are used to determine the condition of the twisted pair cable and the type of cable fault.

Auto Surveillance VLAN and Auto Voice VLAN
The DGS-1210-28P supports Auto Surveillance VLAN (ASV) and Auto Voice VLAN, making it ideal for video surveillance and IP telephony deployments. The feature automatically identifies video and VoIP equipment on the network and separates them into separate VLANs, allowing each to receive the highest priority for video and voice traffic. Support for Auto Surveillance VLAN and Auto Voice VLAN ensures stable video and VoIP applications, quality transmission and maximum protection for multimedia traffic regardless of the overall network load. In addition, the DGS-1210-28P supports automatic detection of ONVIF-compliant equipment such as network cameras and storage devices, as well as a dedicated Web interface mode for easy monitoring of video surveillance systems.

Network security
The D-Link Safeguard Engine feature provides an effective mechanism to protect the switch against viruses and malicious traffic. 802.1X port authentication allows you to use an external RADIUS server for user authentication. In addition, the Access Control Lists (ACL) feature enhances network security by filtering out traffic originating from unauthorized MAC/IP addresses. The DGS-1210-28P also supports ARP Spoofing, which protects the network from attacks that can alter or delay traffic by sending spoofed ARP messages. In order to prevent ARP Spoofing attacks, the switch uses access control lists to block packets containing false ARP messages. To enhance the security, the DHCP Server Screening feature denies access to unauthorized DHCP servers.

Convenient operation
The D-Link Network Assistant automatically detects and displays D-Link WebSmart switches belonging to the same L2 network segment. With this utility, the user does not need to change the IP address of his computer, which simplifies the initial installation of the switch. The user has access to advanced configuration and basic settings of detected devices, such as changing the password and updating the software. The DGS-1210-28P also supports D-View 7 and a simplified command line interface
