Network switches DCN

DCS-3950-28CT PoE Intelligent Access Switch - 24 x 10/100Base-TX + 2 x 100M/Gigabits Combo(SFP/GT) + 2 x 10/100/1000Base-T DCS-3950 series comprises DCS-3950-26C, DCS-3950-28CT and DCS-3950-52CT. Providing high performance in security and operation, DCS-3950 series is an excellent choice as access layer switch for education, government and large/medium enterprise networks. Stacking and various port combination based on fixed uplink ports help to ease the users’ network construction. As switch for new generation network, DCS-3950 series addresses powerful security features. ACL efficiently prevents viruses attack and DOS, DDOS intruding from damage of itself and even core or aggregation layer equipments. Full hardware forwarding and ASIC based ACL policy ensure no effect on normal data when viruses overrun all over the network.

Perfect Configuration

DCS-3950-26C has 2 fixed Combo Gigabit uplink ports allowed to be used as either copper or fiber ports on users’ demand. DCS-3950-28CT and DCS-3950-52CT additionally offer 2 fixed Gigabit copper ports except 2 fixed combo Gigabit ports, accommodating not only direct access to workgroup server but also adequate port choices for uplink, downlink and stacking.

Powerful ACL

As new L2 switch, DCS-3950 series adopts full ACL policy undertaking data classification and employing specific forwarding policy on a per-packet basis by source or destination IP address, source or destination MAC address, TCP/UDP port number, IP precedence, time range and ToS. Implemented ACL policy, users can filter out virus packets such as Blaster, Code Red at the access layer preventing core equipments from being affected or attacked.

Enhanced Security

Full limited multicast policy DCSCM is able to actualize IGMP based ports inspection technology at the edge by effective security control on source and destination ports, roundly protect the upbuilding and stable operating of legal multicast application in the network, and entirely assure switch and server safety through monitoring pingSweep attack, anti-scanning and taking preventing measures.

Network Protocols Supported

DCS-3950 series supports 802.1d/w/s spanning tree protocol, 802.1Q, 802.1p, 802.3ad, 802.3x, GVRP, DHCP standards, and support SNTP to achieve auto-synchronization.

Advanced Quality of Service (QoS)

DCS-3950 series differentiates and classifies traffic flows according to ports, 802.1p, ToS, DSCP, TCP/UDP ports, and assigns specific service hierarchy. The dispatcher WRR/SP supported by DCS-3950 ensures voice/data/video are properly classified and prioritized throughout the network.

Simple Management

DCS-3950 series supports SNMP, in-band and out-band management, CLI and WEB interface, RMON, Security IP function. All help to restrict unauthorized user from access and altering configurations. SSH protocol guarantees security of switches configuration management to the maximum.

Comprehensive Authentication and Accounting Solution

DCS-3950 series supports Digital China Enhanced 802.1x Authentication and Accounting Solution, an authentication method based on ports and MAC address. This solution boosts security performance of DCS-3950 series by denying unauthorized access and prohibiting not allowed IP configuration. Equipped with DCBI-3000, a security access control and accounting system of Digital China, and 802.1x client terminal, DCS-3950 series is enabled to charge according to time and/or traffic, implement a strict binding of account, password, IP, MAC, VLAN, port and switch, prevent agent software, PC clone and message/advertisement to legal users, and even actualize user-based dynamic VLAN and bandwidth authorization and dynamic IP address assignment on group strategy basis. With all these features, DCS-3950 series is ideal for network access operation.
