IRF2 (Second Generation Intelligent Elastic Architecture)
The H3C S5120V3-SI series Gigabit Ethernet switches support innovative IRF (Intelligent Resilient Framework) technology, allowing users to connect multiple S5120V3-SI switches to form a logically independent entity, thereby building a new type of intelligent network with high reliability, scalability, and ease of management.
The H3C S5120V3-SI series Gigabit Ethernet switches support long-distance stacking. Users can stack switches located in different locations over fiber optic cables, forming a logical entity for multiple devices distributed in different areas and locations. The devices are backed up with a 1: N ratio, further improving network reliability and ease of management.
The H3C S5120V3-SI series switches can be virtualized not only through optical interfaces, but also through gigabit electrical ports, and IRF2 functionality can be achieved through Ethernet cables. IRF can bring the following benefits to users:
After the simplified management IRF architecture is formed, it can be connected to any port of any device to log in to a unified logical device. By configuring a single device, the effect of managing the entire intelligent elastic system and all member devices within the system can be achieved, without physically connecting to each member device to configure and manage them separately.
The various control protocols running in the logical devices formed by simplifying business IRF are also uniformly operated as a single device. For example, routing protocols are uniformly calculated as a single device. With the application of cross device link aggregation technology, they can replace the original spanning tree protocol, which can save a large number of protocol packet interactions between devices, simplify network operation, and shorten convergence time during network turbulence.
Elastic expansion can be achieved according to user needs, ensuring user investment. And the newly added devices can achieve "hot plugging" when joining or leaving the IRF architecture, without affecting the normal operation of other devices.
The high reliability of IRF is reflected in three aspects: links, devices, and protocols. The physical ports between member devices support aggregation function, and the physical connections between the IRF system and the upper and lower level devices also support aggregation function. This improves the reliability of the links through multi link backup; The IRF system consists of multiple member devices. In the event of a Master device failure, the system will quickly and automatically elect a new Master to ensure uninterrupted business through the system, thus achieving device level 1: N backup; The IRF system will have a real-time protocol hot backup function responsible for backing up the configuration information of the protocol to all other member devices, thereby achieving a 1: N protocol reliability.
For high-end switches, the improvement in performance and port density is limited by hardware architecture. The performance and port density of the IRF system are the sum of the performance of all devices and the number of ports within the IRF. Therefore, IRF technology can easily increase the switching capability and user port density of devices by several times, thereby significantly improving device performance.
Complete security control strategy
The H3C S5120V3-SI series switch supports innovative single port multi authentication Triple function. In diverse network environments with different client forms, different clients support different access authentication methods. For example, some clients can only perform MAC address authentication (such as printer terminals), some user hosts can perform 802.1X authentication, and some user hosts only want to perform Portal authentication through web access. In order to flexibly adapt to the multi authentication requirements of this network environment, the S5120V3-SI series switches support a unified deployment method of single port multi authentication, allowing users to choose any suitable authentication mechanism for authentication and achieve access through only one authentication method. The client provides Guest Vlan functionality, allowing authorized access to only specific resources and adopting corresponding strategies, such as obtaining 802.1x clients, upgrading clients, or obtaining other upgrade programs. Supporting the Secure Shell V2 (SSH V2) feature can provide secure information protection and powerful authentication capabilities to protect Ethernet switches from attacks such as IP address fraud, plaintext password interception, and more.
ARP attacks and ARP viruses are the top threats to LAN security. The H3C S5120V3-SI series switches support a variety of ARP defense functions, such as ARP Detection, which enables user legitimacy checks and ARP packet validity checks, ARP speed limits, and prevents a large number of ARP packets from impacting the CPU.
The H3C S5120V3-SI series switch supports EAD (Terminal Access Control) function, which, when combined with the backend system, can integrate terminal security measures such as antivirus and patch repair with network access control and access permission control into a linked security system. Through the inspection, isolation, repair, management, and monitoring of network access terminals, the entire network transforms from passive defense to active defense, from single point defense to comprehensive defense, and from decentralized management to centralized policy management, enhancing the overall defense capability of the network against emerging security threats such as viruses and worms.
