Powerful Business Processing Capabilities
• Routing including static routing, dynamic routing and policy routing to realize routing data communication between different network segments. Simpler, more efficient and more reliable.
• DHCP Server and Relay to assign IP address to hosts in the network.
• GVRP(pending) to realize VLAN dynamic distribution, registration and attribute propagation, reduce the amount of manual configuration, and ensure the correctness of configuration.
• QoS, including Port Priority, Priority Mapping, Queue Scheduling, Traffic Shaping and Rate Limit.
• ACL to realize the filtering of data packets by configuring matching rules, processing operations and time schedule, and provide flexible security access control policies.
• IGMP Snooping and MLD Snooping to meet the needs of multi-terminal HD video surveillance and video conference.
• IPv6 to meet the needs of the network transition from IPv4 to IPv6.

Multiple Security Prevention Mechanism
• Static MAC table, dynamic MAC table to allow data transmission, and filter MAC table to avoid network attacks.
• Packet filtering based on binding of IP address, MAC address, VLAN and port.
• Dynamic ARP Inspection to protect against ARP spoofing and ARP flooding attacks such as gateway spoofing, man-in-the middle attacks and etc. that are common in LAN environment.
• IP Source Guard to prevent illegal address spoofing including IP/MAC/ VLAN spoofing and IP/VLAN spoofing.
• DoS Attack Defense, including Land Attack, Smurf Attack, TCP SYN Attack, Ping Flooding and more.
• 802.1X, RADIUS, AAA, TACACS+ authentications to provide authentication function for LAN devices.
• Supports port security. When the number of MAC addresses learned by a port reaches the maximum number, it will be set to error-down status automatically or stop learning to prevent MAC address attack and control the network traffic of the port.
• Supports DHCP Snooping. Only allow DHCP packets from trusted ports to keep the enterprise DHCP environment safe.

Diverse Reliability Protection
• RPS, External redundant power module(optional), ensures stable business use continuously.
• Support fault detection and alarm for power supply and fan, and automatically adjust the fan speed based on temperature changes to better adapt to the environment.
• Multiple reliability protection at device level, such as overcurrent protection, overvoltage protection, overheat technology and 6KV surge protection.
• Dual boot of hardware level. Use two FLASH chips to store boot software(system boot program), achieve hardware level boot redundancy backup, and avoid switching failure due to FLASH chip failures.
• Dual system file redundancy backup ensures the normal startup and operation of the system, and improves the stability of the device.
• STP/RSTP/MSTP to guarantee fast convergence, improve fault tolerance, ensure stable network and provide link load balance, and redundancy.
• Compatible with PVST/PVST+(pending) for faster convergence. Optimizing network performance through VLAN-based network load balance.
• ERPS(pending), loopback detection to identify and remove loops on the network.
• VRRP(pending) to minimize network downtime caused by gateway failure.
• Link aggregation to increase bandwidth, improve reliability and load balancing.
• Storm control to prevent traffic interruption caused by broadcast, multicast or certain unicast packets.
