12+8+1 10Gigabit Fiber Ethernet Switch  JHA-SWG812MG-20BC Product Overview 12+8+1 10Gigabit Data Center Switch is layer 2 non-blocking switch with Broadcom chip. Providing 258Gbps switching capacity and 192Mpps forwarding performance, L2 / L3 full wire-speed forwarding. Its flexible networking capability ensures the stability of the network and the balance of the load link. With the modular design, it provides 12 10G SFP+ optical ports, 8 10/100/1000M RJ45 electrical ports, 1 Console port, 1 OOB management port, which offer enough bandwidth for data aggregation and data exchange. And in order to flexibly respond to the network requirements, users can select appropriate 10G ports according to their needs.With high bandwidth and low latency, pipe network., JHA-SWG812MG-20BC located in density of the next generation of data center and cloud computing network access, can also be used for large Internet cafes, the core of enterprise network, metropolitan area network, or aggregation. Product Feature Remarkable performance 1. With 258Gbps backplane bandwidth, the industry the highest performance (1U TOR); 2. Hardware routing, wire speed packet rate reached 192Mpps, L2 / L3 forward full speed; 3. Able to be deployed in the Metropolitan Area Network and provide several last kilometer technology.    Safe and Reliable 1. Provide DOS, DDOS, spoofing and virus defense; 2. Support IEEE802.1x, provide port-based user authentication, network shield, safety control, and policy control technology; 3. Restrict the maximum number of  hosts connected with the port, multi-binding Ethernet interface , increasing bandwidth and system redundancy; 4. Powerful ACL, support L2-L4 data filtering; 5. Policy control list and flow regulation. Convenient in operation and maintenance 1. Support flexible port configuration; 2. Management support with Web, SNMP and telnet; 3.Support XModem protocol, use TFTP/ZMODEM to software upgrading and BootRom upgrading; 4.Support SFP+, also backwards compatible XFP; 5. Enter or exit low-power condition from PHY. Powerful Flow and Broadcast Management   1. Automatically detect and control broadcast storm, support IGMP packets detection, effectively limit the flooding of broadcast packets; 2. Support Ethernet interface taking 1M as the step length for rate limiting. 3. Support full duplex mode and half duplex mode flow control; 4. Support IP multicast and QoS.
