Hardware-based Intelligent Service
The Versatile Network Processing (VSNP) Service Interface Module of Quidway S6500 series for Salience III and Salience III Plus provides enhanced features. It adds Layer 3 routing table and supports advanced hardware-based Network Address Translation (NAT) and NetStream as well as policy-based routing (PBR) features. Network Address Translation – The Quidway S6500 series can support 32 IP pools and ultimately 8,000 IP address. The Network Address Port Translation (NAPT) enables the mapping of multiple internal addresses to the same public address, thereby enabling multiple internal hosts be able to access external networks simultaneously. The Easy IP feature will ideal when only one public IP address is available or there are a limited number of internal hosts. It can protect equipments against TCP SYN and UDP port-scan attack. NetStream – The VSNP Interface Module supports flowbased statistics monitoring. Data can be exported, collected and analyzed for network-traffic accounting, network monitoring, security alarming and network planning. It can support up to 300,000 stream statistics entries per board. Supposed 64 bytes per packet and single direction, the throughput will reach to 3.8Gbps and the forwarding rate is 5.7Mpps. Policy Based Routing – The VSNP Service Interface Module introduces Network Processor (NP) to guarantee wire-speed forwarding while PBR is configured. It can implement logical usage of bandwidth, link backup and traffic marks. Supposed 64 bytes per packet, the throughput will reach to 3Gbps and the forwarding rate is 4.5Mpps.
Smoothly Upgrade and Backward Compatibility of LPU
Newly released, the S6500 series currently has 4 models, 6 engines, and dozens of interface boards available. All are based on advanced architecture and can perform from access to aggregation and the core layer. With multiple high speed GEBUS and XGBUS between Main Control Units and interface modules, smooth network upgrade is guaranteed from FE to GE and 10GE. And with the GEBUS design in the new Salience III series super engines, all the legacy interface boards will work with the new chassis and switching engines. As a result, TCO (Total Cost of Ownership) for customers is protected, and more choices are available for customers.
Complete Security Mechanism
The Quidway S6500 series deploys the sophisticated 802.1x mode for access user authentication. 802.1x dynamic user binding enables a switch to dynamically bind the IP address, the MAC address, the accessing port, and the VLAN to which the accessing port belongs after an 802.1x user passes the authentication. And the switch then only permits the packets that match all these four items. Guest VLAN allows unauthenticated users to access more resources, without installing 802.1x client, or the user upgrades 802.1x client without authentication. Dynamic VLAN with RADIUS server implements the purpose of controlling the network resources that the users can access. HWTACACS or RADIUS authentication or local server enables centralized access control of switches and limits unauthorized users to modify the configurations. DHCP Security can be used to prevent illegal user from accessing network by binding IP and MAC address on the switch itself. The Quidway S6500 series can also prevent unauthorized access to the network by binding any combination of MAC, IP, VLAN and PORT. The Quidway S6500 series also support Secure Shell (SSH) protocol version 2, secure SNMPv3 NM protocol and MD5 encrypted authentication of OSPFv2, RIPv2 and BGPv4 packets. Salience III Super Engine of the Quidway S6500 series offers superior per-port QoS features to help ensure that network traffic is classified, prioritized, and scheduled optimally to efficiently handle bandwidth-hungry multimedia, time-sensitive (voice), and mission-critical applications. Salience III Super Engine can classify, police, and mark incoming packets, allowing the administrator to differentiate between traffic flows and enforce policies. Sharing, shaping, and strict-priority configurations determine scheduling of egress traffic. Bandwidth control granularity is up to 64 Kbps. Adopting the advanced system ASIC chip design, the longest routing prefix mode and the packet-by-packet forwarding mode, the Quidway S6500 series can effectively combat network viruses like Worm. Blaster, Red Code, etc.
Excellent Power over Ethernet (PoE) Solution
S6500 series switch supports IEEE 802.3af standard PoE as PSE (Power-sourcing Equipment) on 10/100BASE-TX or 10/100/1000 BASE-T ports. All new PoE line cards of S6500 series switch can support up to 48 simultaneous full-powered PoE port per slot at 15.4w. It also supports intelligent power management and delivers necessary power to PD (Powered Device). It could provide up to 2400W power supply with N+1 redundancy. In the network construction, it could provide power directly to any IEEE 802.3af-compliant end device to limit the number of point failure, such as WLAN Access Point device or IP Phone which enables Voice VLAN applications. With PoE and Voice VLAN technology, these innovative switches can provide the perfect solution for a converged voice and data network.
