High reliability for operations

Key system components, such as power modules and fan modules, are all 1+1 backup, support hot plug, and support seamless switching in case of failure without manual intervention.

Supports STP/RSTP/MSTP protocols, VRRP, and features redundant protection mechanisms including ring protection, dual uplink primary/backup link protection, and LACP link aggregation.

The ultra-precise BFD bidirectional link detection mechanism, through coordination with Layer 2 and Layer 3 protocols, enables millisecond-level fault detection and

Business recovery greatly improves the reliability of the network system.

A comprehensive Ethernet OAM mechanism supporting 802.3ah, 802.1ag and ITU-Y.1731, enabling real-time monitoring of network status for rapid fault detection and localization.

The high reliability design of software and hardware meets the 50ms fault recovery time requirement of telecom-grade services, and truly achieves the high reliability of 59s (99.999%) for operational-grade core equipment.

Rich data center features

Supports VxLAN, enabling the construction of Overlay networks in data centers and addressing the limitations of traditional data center networks, such as insufficient VLAN numbers and scalability challenges. New subnets can be created based on Overlay without being constrained by physical network IP addresses or broadcast domains.

Supports the EVPN protocol, providing automatic discovery and authentication of VTEP (Tunnel Endpoint) . This reduces VxLAN data plane flooding and eliminates VxLAN's reliance on underlying multicast deployment, simplifying VxLAN deployment, improving the efficiency of large Layer 2 network construction, and better meeting the deployment requirements of large Layer 2 networks within data centers.

Supports ISS (Intelligent Switch Stack) virtualization technology, which virtualizes multiple physical devices into a single logical device for unified operation and management, reducing network nodes and improving network reliability.

Supports M-LAG cross-device link aggregation, enabling server/switch access for dual-active link aggregation across multiple devices, thereby elevating link reliability from the board level to the device level.

Supports the RoCE protocol, enabling lossless Ethernet low-latency forwarding based on RDMA (Remote Direct Memory Access). This optimizes service forwarding performance, significantly reduces the single-bit cost across the entire network in operations, and enhances the competitiveness of service products.

Enhanced second and third layer features

Fully-featured multicast routing protocols for layers 2 and 3, designed to meet the access requirements of IPTV, multi-terminal HD video surveillance, and HD video conferencing.

Comprehensive three-layer routing protocol with massive routing table capacity, meeting diverse network interconnection requirements, enabling the deployment of large-scale campus networks, enterprise networks, and industry-specific private networks.

Supports L2-L4 packet filtering and provides flow classification technology. It offers flexible queue scheduling algorithms that can be configured for both ports and queues, supporting multiple mechanisms including PQ, WFQ, WRR, and WRED. Additionally, it supports congestion avoidance mechanisms such as WRED and tail drop.

Comprehensive IPv6 solution

Fully supports the IPv6 protocol suite, including IPv6 Neighbor Discovery, ICMPv6, Path MTU Discovery, DHCPv6, and other IPv6 features.

Supports IPv6-based Ping, Traceroute, Telnet, SSH, and ACLs to meet the needs of IPv6-only network device management and service control.

Supports IPv6 multicast features such as MLD and MLD Snooping, and IPv6 Layer 3 routing protocols including static routing, RIPng, OSPFv3, and BGP4+. It provides users with comprehensive IPv6 Layer 2 and Layer 3 solutions.

Supports a wide range of IPv4-to-IPv6 transition technologies, including manual IPv6 tunnels, automatic tunnels, 6to4 tunnels, and ISATAP tunnels, ensuring a seamless migration from IPv4 to IPv6 networks.

Strong security mechanism

Device-level security protection: The advanced hardware architecture design enables hierarchical scheduling and protection of packets, supporting defense against DoS, TCP SYN Flood, UDP Flood, broadcast storms, and high traffic attacks. It also provides command-line hierarchical protection, with different user levels having different management permissions.

Comprehensive security authentication mechanism: Supports IEEE 802.1x, MAC authentication, Radius, Tacacs+, etc., providing users with a complete security authentication mechanism.

Enhanced service security mechanisms: Supports plaintext or MD5 authentication for relevant routing protocols, and uRPF reverse routing lookup technology to effectively control unauthorized services. Hardware-level packet deep inspection and filtering technology enables deep detection of control and data packets, effectively isolating unauthorized data packets and enhancing network system security.

Excellent management skills

Supports multiple management interfaces, including Console, MGMT port, SNMPv1/v2/v3, and universal network management platforms. It provides CLI command-line, Web management, TELNET, and cluster management for easier device administration, while supporting encryption methods like SSH2.0 and SSL for enhanced security.

Supports SPAN/RSPAN mirroring and multiple mirroring observation ports, enabling network traffic analysis for management and maintenance. It provides various network traffic analysis reports to help users optimize network architecture and adjust resource deployment in a timely manner.

Easy configuration and deployment

Supports ZTP (Zero Touch Provisioning) protocol, which automatically loads version files from USB drives or file servers, enabling device deployment without on-site configuration, thereby reducing labor costs and improving deployment efficiency.
