The switch is a full Gigabit management switch, which uses the unique optical port design of the industry, breaking through the limitations of traditional multiplexing ports; reliable switching engine, broadband telecommunication power supply design, fast and efficient loop protection function, escorting the stable operation of your network; international "EEE" environmental protection and energy saving Standard design, effectively saving electricity and money for users.
The switch is a full Gigabit management switch, which uses the unique optical port design of the industry, breaking through the limitations of traditional multiplexing ports; reliable switching engine, broadband telecommunication power supply design, fast and efficient loop protection function, escorting the stable operation of your network; international "EEE" environmental protection and energy saving Standard design, effectively saving electricity and money for users. This series of products provide users with brand-new technical characteristics and solutions in the aspects of security, reliability, multi-service integration, easy management and maintenance. It is the ideal convergence of office network, service network and resident network, access switch and the core switch of small and medium-sized enterprises and branches.
Support L2 level wire-speed port switching, which enables all ports to forward packets without blocking.
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.
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 attacks defence strategies, against for Land attacks, Blat attacks, Ping attacks, TCL controled flag attacks.
Support IEEE 802.1x port authentication, process security authentication for access users.
Support storm suppresstion based on bandwidth adjustment, storm flitering and ACL strategie.
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.
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.
Supports IEEE 802.3az(Energy Efficient Ethernet), port energy detection, CPU variable-frequency and device
