The NSH-2128F is a high-performance Layer 2 switch that supports 12 X Giga optical SFP slots, 16 X  10/100 / 1000Base-T UTP port. NSH-2128F is designed for high speed telecommunications solutions such as enterprise networks, smart apartments and office buildings. NSH-2128F can provide differentiated services by providing port-based bandwidth control and is designed to allow proper mixing of SFP optical slots and UTP ports. The NSH-2128F can provide extra bandwidth through the Port Trunk feature for servers that require a lot of bandwidth or uplink ports. In addition to 802.1p, IP TOS, and TCP / UDP port-based QoS, it provides QoS such as WRR and FCFS to handle various data in multimedia environment. It also supports useful MAC address based filtering and protocol based filtering to filter out certain harmful services and also cope with DDoS threats. The NSH-2128F also supports IGMP Snooping to forward multicasting data, such as IPTV, only to the appropriate ports, helping to prevent overload damage.
