Product Description:

BD-S3400 Series
Full-Gigabit Switches are next-generation aggregation switches developed by for
campus networks and enterprise networks. Developed on the basis of BDROS – a
software platform with its own independent intellectual property rights, BD-S3400
Series provides high-performance L2/L3/L4 wire speed switching capacity by
integrating services such as IPv6, MPLS VPN, network security, flow analysis,
virtualization. With high reliable techniques including continuous forwarding,
graceful restarting and loop network protection, BD-S3400 Series works in
high efficiency and its maximum running time are guaranteed.

BD-S3400 Series
has multiple models: BD-S3424H, BD-S3448C, etc.

Carrier-class High Reliability

n  BD-S3400 Series supports redundancy protection mechanism
such as STP/RSTP/MSTP protocol, VRRP protocol, ring network protection, dual
uplink active/standby link protection and LACP link aggregation.

n  BD-S3400 Series
supports ISSU (In-Service Software Upgrade), guaranteeing the user data
non-stop forwarding when the system is upgrading.

n  BD-S3400 Series supports BFD and realizes fault detection and service
recovery in seconds through linking with layer-2 or layer-3 protocol.

n  BD-S3400 Series has perfect Ethernet OAM, 802.3ah, 802.1ag and ITU-Y.1731
which can real time monitor the network operating state and rapidly detect and
locate the malfunction.

n  MTTR of BD-S3400 Series
is 50ms, meeting the requirement of the carrier-level service.

 Complete POE Power Supply
Function

n   BD-S3400 Series supports 802.3AF/AT standard, built-in
high-power power supply, and 24-port POE+ power supply.

n  BD-S3400 Series supports POE non-stop powering when it is in hot-restart.

n  BD-S3400 Series supports power port priority when the power is not
efficient.

n   BD-S3400 Series supports the POE port with 2KV thunder
prevention.

  Comprehensive Service

n   BD-S3400 Series supports complete layer-2 and layer-3
multicast routing protocol and meets the access requirement of IPTV,
multi-terminal high-definition video monitoring and high-definition video
meeting.

n  BD-S3400 Series supports complete layer-3 routing protocol and a
super-large routing table capacity, which make super-large data center network,
campus network, enterprise network and industry private networks available.

n   BD-S3400 Series supports MCE function. BD-S3400
series can connect with different VPN users in the down-link and connect to the
PE through common physical interface.

 Comprehensive IPv6 Solutions

n   BD-S3400 Series comprehensively supports IPv6 Neighbor
Discovery, ICMPv6, Path MTU Discovery and DHCPv6.

n  BD-S3400 Series supports IPv6 based Ping, Traceroute, Telnet, SSH, ACL,
meeting the need of IPv6 network equipment management and service control.

n  BD-S3400 Series supports IPv6 multicast characteristics including MLD, MLD
Snooping and IPv6 layer-3 routing protocols including IPv6 static routing,
RIPng, OSPFv3 and BGP4+.

n   BD-S3400 Series supports IPv4-to-IPv6 technologies
including IPv6 manual/automatic tunnel, auto tunnel, IPv6-to-IPv4 tunnel, and
ISATAP tunnel.

  Comprehensive Security
Mechanisms

n   BD-S3400 Series adopts advanced hardware architecture
design, realizing the hierarchical scheduling and protection of the packet. It
provides multiple security measures to defend against attacks from SYN Flood,
UDP Flood, broadcast storm and mass flow of DOS or TCP. It also supports
command line authority control based on user levels.

Comprehensive Security Certification

n  BD-S3400 Series complies with IEEE 802.1x, Radius, BDTacacs+.

n Enhanced Service Security Mechanism: BD-S3400 Series supports the plain
text or MD5 authentication of relevant routing protocol; uRRF; DPI (Deep Packet
Inspection) and (Deep Packet Filtration); DPI for control packets and data
packets.

n Innovative Green Environmental Design

n Smart Power Management System: BD-S3400 Series adopts advanced power
system architecture design which can realize the function of efficient power
switching.

n Smart Fan Management System: BD-S3400 Series is designed with the
intelligent fan with little noise.

n BD-S3400 Series supports Efficient Ethernet and complies with
International standard IEEE 802.3az.
