Specifications

4
DCS-3950 series Ethernet switch manual
network at the same time. PVLAN function can divide ports into isolated ports and
community ports, in order to isolate or connect ports as demanded by network
applications.
 QoS
DCS-3950 series fully support QoS policy. Users can specify 4 priority queues on
each port. WRR/SP/SWRR scheduling is also supported. DCS-3950 series also supports
the port security. The traffic can be sorted by port, VLAN, DSCP, IP precedence and ACL
table. User can also modify packets’ DSCP and IP precedence values. Users can specify
different bandwidths for voice/data/video to customize different qualities of service.
 ACL
DCS-3950 series supports complete ACL policy. ACL is a mechanism realized by
switches to filter IP data. By allowing or denying specific data packets entering/leaving the
network, a switch can control the network access and effectively guarantee the secure
operation of network. DCS-3950 series supports IP -based, MAC-based and
MAC-IP-based ingress filtering, it can also filter data based on the information of
source/destination IP address, source/destination MAC address, IP protocol type,
TCP/UDP port, IP precedence, time range and ToS, etc..
 IEEE802.1x Access Authentication
The DCS-3950 series not only supports port-based IEEE802.1x authentication mode,
but also supports MAC -based authentication mode. It can set the upper limit of access
authentication users per port, realize dynamic secure authentication mode basing on MAC
address, and bind the MAC address of authenticated equipment to a port. Combining
these IEEE802.1x authentication modes with the authentication and cost-counting
products of the Digital China Networks Limited, we can supply a whole set of integrated
IEEE802.1x access authentication and cost-counting resolution to satisfy the need of
access, authentication and cost-counting, ensuring the network’s security and its ability to
operate.
 Bandwidth Control (Speed Limit of Port)
The DCS-3950 series can control the upstream/ downstream bandwidth and provide
different access bandwidth for users of different levels. Each port can set its bandwidth
rate as demanded to meet the need of access network to control access bandwidth.
 TRUNK
The DCS-3950 series supports IEEE802.3ad standard TRUNK. It can also realize link
redundancy and traffic load balance.
 IGMP Snooping
The DCS-3950 series supports multicast applications which are based on IGMP
Snooping mechanism, and as a result, it can realize all kinds of multicast services,
diminish the network traffic and meet the requirement of multicast services like multimedia
playing, remote teaching and entertainment.
 Broadcast Storm Suppression
The DCS-3950 series supports broadcast storm suppression, can effectively control
broadcast storm, decrease useless occupancy of bandwidth, and increase the overall
performance of network.
