| STCS4012ST 8 Port Gigabit SFP X 4 Port Gigabt Tx Layer 3 Gigabit Routing Switch Description: | 
| The STCS4012ST is a pure gigabit switch that offers 8 gigabit SFP slots, plus 4 gigabit Tx ports combo. | 
| The STCS4012ST security intelligent multi-layer switch is a new-generation switch for high security | 
| networks. With large capacity and high performance switching, it also features advanced security. It is the | 
| premium option for the convergence layer access control of small or middle-sized MAN, or the access switch | 
| for enterprise users. | 
|  | 
|  | 
| >>> Advanced Security: | 
| Supports comprehensive ACL access control policies, including: user MAC address based ACL,IP protocol | 
| (TCP/UDP) based ACL, TCP port number based ACL, UDP port number based and time based ACL; | 
| Can identify legal service terminals with bounded VLAN-IP-MAC; 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; | 
|   Supports PVLAN, offers strict port segregation within 802.1Q VLAN, ensures high security over service | 
| operation; Patented CPU protection technique checks and filters 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 router and network topology. | 
|  | 
|  | 
| >>> Flexible QOS | 
| The STCS4012ST security intelligent multi-layer switch supports intelligent QoS and meet the high service | 
| quality demand of voice, video and other real-time multimedia services by following technologies: | 
| Priority based on IEEE802.1P tagged information and quintuple flow classification service; | 
| Supports flow-based multilayer CoS and ToS to meet the demand of real-time multimedia service such as | 
| 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 | 
| STCS4012ST security intelligent multi-layer switch supports a rich set of routing technology which covers | 
| almostly all the existing 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. | 
|  | 
|  | 
| >>> Convenient Maintenance and Control | 
| Supports NM methods such as SNMP, CLI, RMON, TELNET, WEB; Supports BOOTP,TFTP and FTP for fast | 
| software upgrading. |
