100 Gigabit access, Gigabit uplink

• The full series supports the combination of "100 Gigabit Ethernet port + Gigabit Ethernet port/optical port", which is convenient for users to flexibly network and meet the networking needs of various scenarios.
• 8/16/24/48 multi-specification port products are provided, and all ports have wire-speed forwarding capabilities to meet the needs of different users.

Strong business processing capabilities

• IEEE 802.1Q VLANs are supported, allowing users to flexibly divide VLANs according to their needs.
• Voice VLANs are supported, and QoS parameters are configured for voice data flows to improve the transmission priority of voice data flows and ensure call quality.
• It supports QoS, three priority modes based on port, 802.1P-based and DSCP-based, and four queue scheduling algorithms of Equ, SP, WRR, and SP+WRR.
• ACLs are supported to filter packets by configuring matching rules, processing operations, and time permissions, providing flexible security access control policies.
• It supports IGMP V1/V2 multicast protocol and IGMP snooping to meet the requirements of multi-terminal HD video surveillance and video conferencing access.
• Multicast VLANs and multicast filtering are supported to efficiently transmit data, save network bandwidth, and reduce network load.
• Port monitoring is supported, and a copy of the data packets of the monitored port is copied to the monitored port to implement network monitoring.

Complete security protection mechanism

• Supports IP address, MAC address, VLAN, and port quaternary binding to filter data packets.
• Supports ARP protection against ARP spoofing and ARP flood attacks, such as gateway spoofing and man-in-the-middle attacks, which are common in LANs.
• IP source protection is supported to prevent illegal address spoofing, including MAC address spoofing, IP spoofing, and MAC/IP spoofing.
• DoS protection is supported, and attacks such as Land Attack, Scan SYNFIN, Xmascan, and Ping Flooding are supported.
• It supports 802.1X authentication, provides authentication functions for LAN computers, and controls the authorization status of controlled ports according to the authentication results.
• Port security is supported, which stops learning when the number of MAC addresses learned on a port reaches the maximum number to prevent MAC address attacks and control port network traffic.

Versatile reliability protection

• Supports STP/RSTP/MSTP SPANNING TREE protocol to eliminate Layer 2 loops and implement link backup.
• Spanning tree security functions are supported to prevent devices in a spanning tree network from various forms of malicious attacks.
• Static aggregation and dynamic aggregation are supported, effectively increasing link bandwidth, implementing load balancing, link backup, and improving link reliability.

PoE power supply function (only supported by PoE models).

• The PoE model supports the IEEE 802.3af/at PoE power supply standard to meet the requirements of PoE power supply in scenarios such as visual security, teleconferencing systems, and wireless coverage.
• You can set the power supply control of PoE ports based on user-defined time periods on the web management interface.
• You can configure the PoE port priority on the web management interface, and when the remaining power is insufficient, the power supply of the high-priority port is guaranteed.
• In PoE models, the maximum PoE output power per port can reach 30W, and users can set the maximum power that can be provided by the port on the web management interface.

Easy operation and maintenance

• Supports multiple management and maintenance methods, such as web management, CLI command line (console, Telnet), and SNMP (V1/V2/V3).
• Supports HTTPS, SSL V3, TLSV1, SSHV1/V2 and other encryption methods for safer management.
• RMON, system logs, and port traffic statistics are supported, which is convenient for network optimization and transformation.
• Supports cable detection, ping detection, and Tracert detection operations to easily analyze faulty network nodes.
• It supports LLDP, which is convenient for the network management system to query and judge the communication status of the link.
• CPU monitoring, memory monitoring, ping detection, Tracert detection, and cable detection are supported.
