Security Layer 3 Routing Switches,L3 Routing Switches security intelligent multi-layer switch is a new-generation switch for networks demanding security, multi-service and high performance. Besides the large capacity and high performance of the traditional layer 3 switches, it also features advanced security. It is the premium choice as the layer 3 switches in the convergence layer for small or middle-sized MAN, the core switch for communities or the access switch for enterprise users. 4012 series is full gigabit switch, it includes three types: 4012S: 12 ports 1000M SFP interfaces; 4012ST: 8 ports 1000M SFP interfaces, 4 ports 10/100/1000 1x5 BiDi Asymmetric Data Rate Module,WDM Asymmetric Data Rate Module Base-T interfaces; 4012TS: 12 ports 10/100/1000 Base-T, 4 ports 1000M SFP combo interfaces. Advanced Security Supports comprehensive ACL access control policies, including: user MAC address based ACL,1x5 Singlemode Optical Transceiver,Singlemode Optical Transceiver  IP protocol (TCP/UDP) based ACL, TCP port number based ACL,1x9 Series Transceiver Optical Modules,1x9 Transceiver Optical Modules UDP port number based and time based ACL; Can identify legal service terminals with bounded VLAN-IP-MAC;4E11 8E1 16E1 PDH Fiber Optical Multiplexer ,china PDH Fiber Optical Multiplexer manufacturer  supports user access control protocol 802. 1x, provides more efficient user port control than the traditional method; The port MAC address limitation function can control the host number accessing the specified port;GBIC Optical Fiber Transceiver,GBIC Fiber Optic Transceiver  Supports PVLAN, offers strict port segregation within 802. 1Q VLAN, ensures high security while ensuring service operation; Patented CPU protection technique checks and filters GBIC Transceiver Optical Modules the data sent to the CPU to avoid malicious attack; Several authentications for protocols such as RIP, OSPF, etc. (plain text authentication, MD5 authentication) to ensure the controllability of the route and network topology, offering higher security; Flexible Quos 4012 series security intelligent multi-layer switch Optical Fiber Transceiver -1X9,1X9 Optical Fiber Transceiver supports intelligent QoS to meet the high service quality demand of voice, video and other real-time multimedia services by following technologies: Priority based on IEEE802.Optical Fiber Transceiver,SFP CWDM Optical Fiber Transceiver  1P tagged information and quintuple flow classification service; Supports flow-based multilayer COS and TOS to satisfy the demand of real-time multimedia service such as Optical Fiber Transceiver,SFP Optical Fiber Transceiver video conference; Self-defined multilayer flow classification rules, with 1024 flow rules supported in one device; 8 priority queues supported per port, with congestion prevention and flow-shaping; Comprehensive routing protocol support 4012 series security intelligent multi-layer switch supports a rich set of Security Layer 3 Routing Switches,L3 Routing Switches routing technology which covers almost all current routing technologies. Supports unicast routing protocols: RIP V1, RIP V2, OSPF, BGP, static routing; Supports multicast routing protocols: IGMP, PIM-SM; Supports redundancy backup protocol: VRRP.
