H3C S7000X New Generation Campus Core Switch
The H3C S7000X switch is an Ethernet switch product independently developed by H3C Technology Co., Ltd. (hereinafter referred to as H3C). It is a third-generation campus core switch designed for network environments that require high performance, high port density, high speed, and easy installation and expansion.
The H3C S7000X series Ethernet switch provides 10/100/1000Base-T adaptive Ethernet ports, SFP, and SFP+optical ports. In enterprise networks, it can serve as a core device to provide high-density 10 Gigabit downlink access and large capacity uplink bandwidth; In metropolitan area networks or industry users, gigabit access can be provided to end-users or converged to low-end switches downwards, and can be aggregated to the wide area network through 10G fiber optic or link aggregation upwards.
The H3C S7000X series Ethernet switches support innovative IRF (Intelligent ReE Client Framework) technology, allowing users to connect two switches to form a logically independent entity, thereby building a new type of intelligent network with high reliability, scalability, and ease of management.
Product Features
Distributed Multi Engine Design
Adopting innovative hardware design, the system provides powerful control capabilities and millisecond level high reliability assurance through fully distributed independent control engines, detection engines, and maintenance engines
Distributed control engine, all business boards provide powerful control processing systems that easily handle various protocol and control messages, and support fine control of protocol messages, providing the system with comprehensive resistance to protocol message attacks.
Distributed detection engine, all business boards can perform fast fault detection such as BFD and OAM in a distributed manner, and are linked with control plane protocols to support fast protection switching and convergence. It can achieve millisecond level fault detection and ensure uninterrupted business operations.
Distributed maintenance engine, intelligent CPU system supporting intelligent power management, can support online status check of devices, sequential power on and off of single boards (reducing power impact caused by simultaneous power on of single boards, improving equipment life, reducing electromagnetic radiation and system power consumption).
IRF2 (Second Generation Intelligent Elastic Architecture)
The H3C S7000X series switches support IRF2 (Second Generation Intelligent Elastic Architecture) technology, which connects two physical devices to each other and virtualizes them as a logical device. In other words, users can manage and use these multiple devices as a single device. IRF can bring the following benefits to users:
After the formation of the simplified management IRF architecture, it is possible to connect 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.
• Easy to manage. The entire elastic architecture shares a common IP management, simplifying network device management, network topology management, improving operational efficiency, and reducing maintenance costs.
Comprehensive IPv6 solution
The S7000X series fully supports the IPv6 protocol family, including IPv6 static routing, RIPng, OSPFv3, IS-ISv6, BGP4+and other IPv6 routing protocols.
Programming language extensions
Built in Tcl (Tool Command Language) parser, supporting direct execution of Tcl script commands on devices to configure devices through Tcl scripts.
Python is a simple, easy to learn, and powerful programming language that features efficient high-level data structures and enables simple yet effective implementation of object-oriented programming. Python's concise syntax and support for dynamic input, combined with the nature of an interpreted language, make it an ideal scripting language for many fields on most platforms, particularly suitable for rapid application development. The system can be automatically configured by executing Python scripts; Configure the device using Python commands, standard APIs, or extended APIs.
Three plane security guarantee mechanism
H3C S7000X provides a comprehensive security protection mechanism to ensure network security from three aspects: control, management, and forwarding. In the control plane, it has a built-in protocol packet attack identification module to prevent ARP protocol packet attacks. The OSPF/BGP/IS-IS routing protocol uses MD5 verification to prevent network paralysis caused by illegal routing updates; In the management plane, the SNMPv3 network management protocol, SSH V2， User authentication based on 802.1x, AAA/Radio, and hierarchical user permission management ensure the security of device management; In the forwarding plane, it supports precise binding of various combinations such as IP, VLAN, MAC, and ports; Support uRPF unicast reverse path forwarding to prevent illegal traffic from accessing the network. Adopt the longest matching packet by packet forwarding mechanism to effectively resist virus attacks.
Enhanced ACL features
The H3C S7000X series products support powerful ACL capabilities: supporting standard and extended ACLs; Support VLAN based ACL for convenient user configuration and saving ACL resources; Support ACL for both outbound and inbound directions, meeting the strict access control requirements of industries such as finance.
