Overview:

Features:

• 1U box-shaped switch with 48 GE ports and 8 10GE ports with high-performance ASIC switch chip
• 64K MAC and 64K routing items.

• Innovative BVSS (BDCOM Virtual Switch System): virtualize multiple physical devices into one. The performance, reliability and management of the virtual system are superior to the physical ones.
• Improved Performance : BVSS makes full use of each link in the physical devices, which avoids STP blocking the link and protects the original link to the maximum extent.
• High Reliability : Based on the advanced distribution mechanism and efficient cross-physical link aggregation link function, the logic control plane, service control plane and service data plane are separated. Thus, the device can support continuous layer3 routing forwarding, avoiding service interruption as a result of a single point of failure.
• Easy Management : BVSS realizes single IP management, greatly improving the networking efficiency and lowering the operating cost.

• Based on HPS (Hitless Protection System), the key components of S3700 series such as the power module support dual back-up, hot-swap, seamless switching in the downtime without manual intervention.
• Supports STP/RSTP/MSTP, VRRP protocol, Ethernet ring protection, dual master-slave uplink protection and LACP link aggregation.
• Supports ISSU (In-Service Software Upgrade).
• Supports BFD mechanism.
• Supports Ethernet OAM mechanism, 802.3ah, 802.1ag and ITU-Y.1731.
• High reliability (99.999%): MTTR of S3700 Series is 50ms, meeting the requirement of the carrier-level service.

• Supports layer2 and layer3 multicast routing protocol, which enable the device can access to IPTV, HD video surveillance and HD video conference.
• Supports layer3 routing protocol and super-large routing table capacity, which enables the device is available in large campus networks, enterprise networks and industry networks.
• Supports layer2 and layer3 MPLS VPN.

• Supports the IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6, path MTU discovery, DHCPv6, etc.
• Supports Ping, Traceroute, Telnet, SSH, ACL.
• Supports MLD, MLD Snooping, IPv6 static routing, RIPng, OSPFv3 and BGP4+, etc.
• Supports IPv6 tunnel: manual tunnel, automatic tunnel, GRE tunnel, 6to4, ISATAP
• Supports IPv4 transits to IPv6: IPv6 manual tunnel, automatic tunnel, 6 to 4 tunnel, ISATAP tunnel.

• Equipment-Level Security : The advanced hardware infrastructure design realizes the level-based packet schedule and packet protection, prevents DoS-/TCP-related SYN Flood, UDP Flood, Broadcast Storm or large traffic attacks, and supports level-based command line protection, endowing different levels of users with different management permissions.
• Security Authentication Mechanism : IEEE 802.1x, Radius and BDTacacs+
• Enhanced Service Security Mechanism : supports the plaintext or MD5 authentication of relevant routing protocol, URPF, deep inspection of hardware packet, control packet and data packet and filtering technology.

• Intelligent power management: The power system of S3700 series supports real-time monitoring the device and the slow-start. It is also power-saving.
• Intelligent fan management system: The fan system of S3700 Series supports automatic speed regulation, which efficiently slow the fan speed and mitigate the noise.
• Comply with the international standard IEEE 802.3az.
