■  Non-blocking High-speed Forwarding
Support L2 level wire-speed port switching, which enables all ports to forward packets without blocking. 

■   Comprehensive Security Control Policies
Support link aggregation to enhance the network bandwidth and defend the network security with link backup.
Support multiple spanning tree protocols: STP, RSTP,provide rapid convergence and improved fault-tolerant capacity. The network sable operation and load balance are well guaranteed, also improved the reasonable use of network channels and redundant link.
Support the binding of user access interface, IP addresses and MAC addresses, to defend against inner network ARP attacks and Dos attacks.
Support the Back-pressure traffic control under Half-Duplex mode and IEEE 802.3x traffic control under Full-Duplex mode. The heavy traffic data peak can be switched stably without the concern of network paralysis caused by overload.

■   Convenient and Quick Management and Maintenance
Adopt simple visual Web-based interface, which helps users to handle various functions easily and conveniently. 
Support Simple Network Management Protocol (SNMP) that the devices are convenient to configure and manage. Small and medium-sized enterprise customers can centralized manage the switch easily.
Support CLI command line management, suitable for professional network administrators.
Support Port Mirror Function, can monitor the ingress, egress or bi-direction packets.
Support resetting to factory defaults, make the maintenance more easily.

■    Innovative Energy Saving Design, the leader of low-carbon communication
Supports IEEE 802.3az(Energy Efficient Ethernet), port energy detection, CPU variable-frequency and device hibernate technology, greatly reducing energy consumption and noise without compromising performance and stability.
