Blog outline:

First, Huawei product classification 2, Huawei network equipment operating system: VRP3, Huawei network equipment simulator and basic configuration commands 1. Huawei product classification:

At present, Huawei's network products include routers, switches and firewalls.

1. Router

Routers are mainly divided into AR series and NE series:

AR series routers: AR series is a new generation of network products launched by Huawei, mainly for enterprises and branch offices. The AR series integrates routing, switching, 3G, voice and security functions, and uses multicore CPU and non-blocking switching architecture to improve system performance to meet the diversified business needs of enterprise applications. Its series of products include AR3200, AR2200, AR1200, AR120 and so on. NE series routers: NE series routers are high-end router products launched by Huawei for operator data communication networks, which cover backbone networks and metropolitan area networks, and can also be applied to large enterprise backbone networks. It adopts distributed architecture and advanced fast forwarding technology, which greatly improves the data processing capacity, supports hot-swappable modules, and is easier to expand. Its series of products are NE5000E, NE40E-X3, NE40E-X8, NE40E-X16, NE20E-S4, NE20E-S8, NE20E-S16, ME60-X3, ME60-X8, ME60-X16.

2. Switch

The switches are mainly small Business Series and CE Series:

S-Series switches are mainly for enterprises. Its series products are: S6700-EI, S5700-SI, S5700-EI, S5700-LI, S5700X-LI, S5700X-LI-24S, S5710-HI, S3700-SI, S3700-EI, S3700-HI, S2700-SI, S2700-EI, S2750-EI, S2751-EI. CE series switches are mainly oriented to the data center, their performance and functions are more powerful than S-series switches, and support advanced features of the data center. Its series products are: CE12816, CE12812, CE 12808, CE 12804, CE6850-48S4Q-EI, CE6850-48T4Q-EI, CE5850-48T4S2Q-HI, CE5850-48T4S2Q-EI, CE5810-24T4S-EL and so on.

3. Firewall

Huawei's enterprise-class firewall is mainly USG series, which integrates a variety of security functions, such as traditional firewall, * *, * * defense, anti-virus, data anti-leakage, bandwidth management, Internet behavior management, and so on, to provide comprehensive, simple and efficient network security protection for enterprises. Its series are: USG2100/2200, USG5100/5500, USG6300/6600, USG9500 and so on.

Second, the operating system of Huawei network equipment: VRP

The operating system used by Huawei's data communication products is VRP (versatile routing platform, general routing platform), which takes IP business as the core and adopts component-based architecture. It not only realizes rich functional features, but also provides application-based tailored and expandable functions.

VRP provides the following features:

Achieve a unified user interface and management interface, including a unified real-time operating system kernel, IP soft forwarding engine, routing processing and configuration management pages. The function of control plane is realized, and the interface specification of forwarding plane is defined to realize the interaction between each product forwarding plane and VRP control plane. Realize the network interface layer and shield the differences of each product link layer to the network layer.

Note: plane, which is a concept in Huawei VRP, describes the hierarchical structure of VRP. VRP locates different business functions in different planes, and each function is only responsible for the specified functional modules. For example, the control plane is used to manage and control the operation of all network protocols, and the management plane is for network managers to use Telnet, SSH, web and other ways to manage devices.

Third, the simulator and basic configuration commands of Huawei network equipment:

1. Installation, registration and command view introduction:

Those who have come into contact with Cisco devices know GNS3, Cisco Packet Tracer and other simulators, these two simulators can well simulate the configuration environment of Cisco devices. Then Huawei naturally also has its corresponding simulator, that is eNSP, about this simulator, you can click to download, extract code: vsu0. Installation is relatively simple, select the installation path, no brain can be the next step, after the installation is completed, the default need to register the device, registration method: click the "menu" in the upper right corner, as follows:

(1) Click as follows:

(2) look at the picture:

(3) introduction to VRP command view:

The individual command views in VRP are as follows:

When you log in to the device for the first time, you enter the user view. Much like Cisco, Huawei devices have only two layers on the configuration mode view: the user view and the system view.

The user view is equivalent to Cisco's user mode. The system view is equivalent to Cisco's global mode.

Usually, the user view can only be viewed simply, and many configuration commands need to be configured in the system view and other business views. You can enter other business views by using relevant business commands from the system view, and different commands can be used in different views.

2. Basic configuration commands of Huawei network device VRP (all commands support "?" Online help and "Tab key auto-add" or command abbreviation):

System-view # is represented as a user view. Execute this command to enter the system view [Huawei] interface Serial0/0/0 # enter the interface view [Huawei-Serial0/0/0] quit # back from the interface view to the system view [Huawei]? # also supports "?" , get the supported command [Huawei] display history-command # query history command [Huawei] sysname Router1 # change hostname [Router1] display version # display system version [Router1] display users # display the connected end user [Router1] display this # query the running configuration of the current view A very practical command [Router1] display diagnostic-information # displays all the status information of the device. I feel it is not very practical [Router1] display saved-configuration # to view the saved router configuration [Router1] display current-configuration # to view the current router configuration, which is equivalent to the "show run" command [Router1] quit # in Cisco. Go back to the user view save # to save the current configuration. This command is supported only in the user view. Reset saved-configuration # erases the router configuration file in the storage device and only supports comparing the configuration file in the user view using compare configuration # to compare whether the current configuration is consistent with the configuration file saved in the storage device

3. ENSP connects to the virtual machine:

Like GNS 3, bridging virtual machines is also supported for more functional testing, and the methods to bridge virtual machines are as follows:

4. VRP configure the router IP address:

Sys # enter the system view [Router1] int e0amp 0 Universe 0 # enter the specified interface [Router1-Ethernet0/0/0] ip add 192.168.1.1 24 # configure IP address, support write mask bits [Router1-Ethernet0/0/0] undo shut # enable this interface

5. Configure Telnet (router and switch configuration commands are the same):

[Router1] user-interface vty0 4 # enter vty user view [Router1-ui-vty0-4] authentication-mode password # Select authentication mode: password [Router1-ui-vty0-4] set authentication password simple 12345 password configure Telnet password 12345 password encryption mode can be configured with plaintext (simper) and ciphertext (cipher). Plaintext is used here. [Router1-ui-vty0-4] user privilege level 3 # sets the user level to management level # ("0" is the visitor level, "1" is the monitoring level, "2" is the configuration level, and "3mur15" is the management level)

After the above configuration, you can use HyperTerminal tools to configure routers or switches for Telnet management.
