Excellent and Secure Traffic Control
The SGS-6340-20S4C4X is loaded with powerful traffic management and WRR features to enhance services offered by telecoms and enterprises. The WRR functionalities include wire-speed Layer 4 traffic classifiers and bandwidth limitation which are particularly useful for multi-tenant unit, multi-business unit, Telco, or network service applications. The ACL policies supported can classify the traffic by source/destination IP addresses, source/destination MAC addresses, IP protocols, TCP/UDP, IP precedence, time ranges and ToS. Moreover, various policies can be conducted to forward the traffic. The SGS-6340-20S4C4X also provides IEEE 802.1x port based access authentication, which can be deployed with RADIUS, to ensure the port level security and block illegal users. Thus, the SGS-6340-20S4C4X empowers ISP and enterprises to take full advantage of the limited network resources and guarantees the best performance in VoIP and video conferencing transmission.

Flexibility and Extension Solution
The SGS-6340-20S4C4X provides twenty-four 100/1000Mbps dual speed SFP Fiber ports, four 1/10Gbps SFP+ Fiber ports, and four 10/100/1000Mbps TP/SFP combo ports. Each of the SFP+ slots supports Dual-Speed,10GBASE-SR/LR or 1000BASE-SX/LX. Therefore, the administrator can flexibly choose the suitable SFP transceiver according to not only the transmission distance, but also the transmission speed required. The distance can be extended from 550 meters to 2km (multi-mode fiber) or up to 10/20/30/40/50/70/120 km (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
