VxLAN features
The H3C S6520X-EI series switch supports VXLAN (Virtual Extensible LAN). VXLAN encapsulates data packets sent by virtual machines in UDP and uses the IP/MAC of the physical network as the outer header for transmission over the physical IP network. Upon arrival at the destination, the packet is unblocked by the tunnel endpoint and sent to the target virtual machine, solving the problem of long-distance virtual machine migration between geographically dispersed data centers. It supports EVPN mode.
Visualization ability

IRF2 (Second Generation Intelligent Elastic Architecture)
The S6520X-EI series switch supports IRF2 (Second Generation Intelligent Elastic Architecture) technology, virtualizing multiple devices (up to 9) into one logical device. It has strong advantages in scalability, reliability, overall architecture, and availability, mainly reflected in four aspects:
Scalability: IRF2 technology allows switches to expand multiple devices using interconnect cables; It has the advantages of plug and play, single IP management, and synchronous upgrading, while greatly reducing the cost of system expansion.
Reliability: Through routing hot backup technology, redundant backup and uninterrupted three-layer forwarding of all information in the control plane and data plane are achieved throughout the entire IRF group, greatly enhancing the reliability and high performance of the IRF group, while eliminating single points of failure and avoiding business interruption.
Distributed: By using distributed link aggregation technology, multiple uplink links can share the load and backup each other, thereby improving the redundancy of the entire network architecture and the utilization of link resources.
• Availability: The intelligent elastic architecture is implemented through a standard 10 Gigabit Ethernet interface, which can allocate business bandwidth and system connection bandwidth according to demand, and allocate local and upstream traffic reasonably; Not only can it achieve intelligent and elastic architecture within racks, across racks, and even across regions over long distances.
IRF3.1 (Vertical Virtualization)
The H3C S6520X-EI switch product supports IRF3.1 (Intelligent Resilient Framework 3.1) vertical virtualization technology, which adds access devices as remote interface boards to the main device system through 802.1BR technology, virtualizing core layer devices and access layer devices as a logical device in the vertical dimension to expand I/O port capabilities and achieve centralized control and management. IRF3.1 technology can simplify management and significantly reduce network management nodes; Simplify the wiring compression network hierarchy and ultimately achieve data forwarding plane virtualization. IRF3.1 vertical virtualization technology can bring the following benefits to users:
Unified management: After the IRF3.1 architecture is formed, all members within the architecture can be centrally configured and managed by connecting to the main device, without physically connecting to each member device for separate configuration.
Unified security policy: The security policy of the entire network only needs to be configured on the main device, avoiding potential policy conflicts caused by configuring each device on the entire network and significantly reducing the workload of security deployment.
Simplify network hierarchy: Supports large-scale remote interface board expansion capabilities. The traditional networking structure that requires a three-layer network architecture can be simplified to a two-layer networking structure through IRF3.1, simplifying the physical and logical hierarchy of the network and wiring.
Simplify business: Various business configurations in the IRF3.1 architecture are based on a single logical device, which can greatly simplify planning considerations such as VLANs, IPs, and routing for the entire network.
• Convenient maintenance: The configuration and software versions of all connected devices are automatically assigned by the main device. When new devices are added or removed, "hot plugging" and zero configuration can be achieved without affecting the normal operation of other devices. The troubleshooting of the entire network is also single point.

MACsec hardware encryption
Macsec is a hop by hop link layer security protocol that is highly suitable for Ethernet. It achieves the following three functions:
1) Message encryption: By using encryption algorithms and keys, plaintext is transformed into scrambled ciphertext, which is difficult to decrypt even if eavesdropped.
2) Anti replay attack: To prevent hackers from intercepting messages received by the destination host and sending them back to the destination host, in order to deceive the destination host, such as identity authentication.
3) Anti tampering: preventing hackers from arbitrarily tampering with the original message content to achieve undisclosed purposes.
The implementation of MACSEC can be divided into two modes:
1) Host oriented mode: used for first hop protection of terminal access to the network.
2) Device oriented mode: Protection of interconnection links between user devices.
