Innovative Virtual Cluster Switching Technique

S2900 L3-lite Series virtualizes multiple physica devices into one. The performance, reliability and management of the virtual system are superior to the physical one.

Improved Performance: BVSS system makes full use

 High Reliabilitv: Based on the advanced distribution mechanism and effi cient cross-physical link aggrega- tion link function, the logic control plane, service control plane and service data plane are separated. Thus, S2900 L3-lite Series can support continuous laver-3 routing forwarding, avoiding service interrup- tion as a result of a single point of failure.

Easy Management: BVSS realizes single lP manage- ment, greatly improving the networking effi ciency and lowering the operating cost.

Industrial Ethernet Ring with Zero Delay and Zero Packet Loss

Supports industry-level EAPS and their protection shift time is less than 50ms. Their high reliability is represented by the null packet loss, which has been proved by many years of application in the Grid, rail transportation and defense systems.

Telecom-Level Ethernet Switch

Support system status LED, port dynamic lED Provides the perfect Ethernet OAM mechanism to monitor the network running status in real time for rapid trouble locating and detection.

Supports powerful ACL functions to access and control L2-L7 data based on physical port, VLAN, MAC, IP and protocol port ID, and providing carriers flexible and various policy control methods.

Supports In-Service Software Upgrade (ISSU) to ensure the unremitting data forwarding during system upgrade.

Supports various L2 multicast functions, including IGMP-Snooping, fast-leave and trans-vlan.

Flexible and Convenient Management and Maintenance

Supports management modes such as the console port, Telnet, SSH, etc. Supports the WEB manage- ment mode, which is easy and efficient so that it makes installation and debugging convenient.

Supports TFTP-patterned file upload/download management.

Supports ISSU (In-Service Software Upgrade). Supports SNMP and NMS smart network manage- ment platform to realize automatic equipment discovery, network topology manage- ment, equipment configuration management, performance data statistics and analysis and trouble management

Carrier-Level QoS Policies

Supports priority retagging and complicated flow classification based on VLAN, MAC, source address, destination address, IP or priority to better streamline carrier’s services.

Supports provides flexible bandwidth control policies and supports port-/flow-based flow limit, and ensuring the line speed forwarding of each port to make sure the high quality of video, audio and data services.

Supports 8 priority queues by each port.

Supports multiple queue schedule algorithms such as SP, WRR, and SP+WRR”.

Intelligent PoE+

S2900-24P4X and S2900-48P6X support IEEE

802.3af/at PoE standard,and power mapping scales up to a maximum of 740W of PoE+ power;

S2900-24P4X and S2900-48P6X support PoE non-stop power supply.

The PoE+ power is maintained during a switch reload. S2900-24P4X and S2900-48P6X support manual and dynamic PoE power allocation;S2900-24P4X and S2900-48P6X support up to 6KV thunder-proof of the PoE port and power supply.

Versatile IPv6 Solutions

Supports the IPv6 protocol suite, IPv6 neighbor discovery, ICMPv6, path MTU discovery, etc.

Supports Ping, Traceroute, Telnet, SSH, ACL and so like on the basis of IPv6, meeting IPv6 networks' equipment management requirements and service control requirements.

Perfect Security Mechanisms

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.

Supports perfect security authentication mecha- nisms: IEEE 802.1x, Radius and Tacacs+. Supports storm/multicast/unicast limit to ensure the normal running of equipment in harsh network conditions. Supports a perfect ring detection mechanism to ensurethe long-term stable running of network.

Supports port isolation within the same VLAN, DHCP-Snooping, and IP plus MAC plus Port binding for ensuring user data security;
