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

■  High Speed and Efficiency Ring Protection
Real-time Monitoring: Built-in configuration-free ring protection, can provide real-time monitoring and find the network rings without delay.
Quick Alarm: The built-in buzzer quickly alarm when a ring is found , to warn the network administrator of ring problems.
Precise Localization: The ring problem interface indicator will flash slowly and periodically to help the network administrator precisely localize the ring port without any delay.
Intelligent Blocking: The switch can automatically block ring port when detect a ring problem, which can efficiently avoid broadcast storm caused by ring problem and secure the normal network communication.
Auto-recovery: After the ring problem is removed, the network will recover automatically, the buzzer stop alarming and ring port back to normal work.

■  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.

■  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.
