Shulou(Shulou.com)06/01 Report--

Huawei's network equipment is roughly the same as Cisco's network equipment in principle. The difference is that Huawei has a lot of proprietary technology. There are network equipment that have studied Cisco, of course, it is not troublesome to learn from Huawei. At present, the network deployment of many enterprises is mixed deployment, that is, the mixed use of multi-vendor equipment. Hybrid deployment not only reduces costs without affecting functionality, but also gives play to the advantages of each vendor. Therefore, it is very important to master the management of network equipment from mainstream manufacturers.

Due to the rapid development of Huawei in recent years, it has been familiar to people at home and abroad, so there are no more introductions here! Let's take a look at Huawei's equipment.

1. Huawei product line

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 adopts multi-core CPU and non-blocking switching architecture to improve system performance and meet the diversified business needs of enterprise applications. As shown in the figure:

NE series routers: NE series routers are high-end router products launched by Huawei for operator data communication networks. Its products cover backbone network and metropolitan area network, and can also be applied to the backbone network of large enterprises. It adopts distributed architecture and advanced fast forwarding technology, which greatly improves the data processing capacity and supports hot-swappable modules. It is easier to expand. As shown in the figure:

two。 Exchanger

The switches are mainly S-series and CE series. Among them, S-series switches are mainly for enterprises, and CE series switches are mainly for data centers. Its performance and function are more powerful than S-Series switches and support advanced features of the data center. As shown in the figure:

3. Firewalls

Huawei's enterprise-class firewall is mainly USG series, which integrates a variety of security functions, such as traditional firewall, illegal entry prevention, anti-virus, data anti-leakage, bandwidth management, Internet behavior management and so on. As shown in the figure:

II. Overview of VRP, a general routing platform

General routing platform VRP is the general operating system platform of Huawei's data communication products and the network operating system of Huawei's independent intellectual property rights. It takes IP service as the core and adopts component-based architecture, which not only realizes rich functional features, but also provides application-based tailored and expandable functions.

VRP platform provides comprehensive software features, and each product adapts these VRP platform features according to its own network positioning and customer needs. It serves as the core engine of Huawei's software for a full range of routers, Ethernet switches, business gateways and other products from low end to core.

VRP provides the following features:

(1) implement a unified user interface and management interface, including a unified real-time operating system kernel, IP soft forwarding engine, routing processing and configuration management plane

(2) realize the control plane function, define the forwarding plane interface specification, and realize the interaction between each product forwarding platform and the VRP control plane.

(3) realize the network interface layer and shield the differences of each product link layer to the network.

Overview and installation methods of eNSP software

If you want to learn Huawei's network well, then the simulator is essential. Huawei's better simulator is eNSP. You can choose to download from Huawei or through the network disk link: link: https://pan.baidu.com/s/1lhGn7JQ6Q8_ofyLdBAh7uA

Overview of 1.eNSP

ENSP is a free, scalable and graphical network simulation tool platform provided by Huawei, which mainly simulates enterprise routers and switches, perfectly presents the real equipment scene and supports large-scale network simulation, so that the majority of Huawei technology enthusiasts have the opportunity to simulate exercises and learn network technology without real equipment.

Huawei's technical team has been updating and upgrading its eNSP software, and today, eNSP software can perfectly simulate Huawei's real equipment.

ENSP has the following remarkable characteristics:

(1) graphical operation

(2) High degree of simulation

(3) can be docked with real equipment

(4) distributed deployment

ENSP is a Huawei network equipment simulator published on the official website. I highly recommend that while learning Huawei's network technology, we should combine eNSP to simulate the network environment, combine theory with practice, deepen technical understanding, improve analysis ability, and understand network phenomena, so as to lay a foundation for the future development of the network industry.

As for the installation of the eNSP simulator is very simple, it is simply brainless next step, so there is no more introduction here! When you install the eNSP simulator, you will also install WinPcap, Wireshark, VirtualBox and other tools. These are all for the authenticity of the simulation.

When you use eNSP for the first time, you need to register it first, otherwise the device will not load properly. As shown in the figure:

two。 Bag grab analysis

The biggest function of eNSP simulator is to capture packet analysis, as shown in the figure:

The command is as follows:

Router configuration:

System-view / / enter the system view Enter system view Return user view with Ctrl+ Z.[ Huawei] interface GigabitEthernet0/0/0 / / enter the interface [Huawei-GigabitEthernet0/0/0] ip add 192.168.1.1 255.255.255.0 / / set IPOct 12 2019 11:25:58-08:00 Huawei% IFNET/4/LINK_STATE (l) [1]: The line protocol IP on the interface GigabitEthernet0/0/0 has entered the UP state. [Huawei-GigabitEthernet0/0/0] the device interfaces of undo shutdown / / Huawei are enabled by default, so this command can be used without typing Info: Interface GigabitEthernet0/0/0 is not shutdown.

The configuration of PC is as follows:

Let's start sending ping packets and start grabbing packets:

Check the contents of the bag, simple and clear!

Fourth, the common configuration of VRP 1. Command View

Huawei's command line is divided into a variety of views, familiar with the role of views and switching methods are skills that Huawei beginners must master.

Each command view of VRP, as shown in the figure:

When we log in to the device for the first time, we enter the user view. This is very similar to Cisco devices.

Huawei devices have only two layers on the configuration mode view: the user view and the system view.

The user view is equivalent to the user mode of the Cisco device, and the system view is equivalent to the global mode of the Cisco device. The common commands are as follows: system-view / / enter the system view Enter system view Return user view with Ctrl+ Z.[ Huawei] interface GigabitEthernet0/0/0 / / enter interface view [Huawei-GigabitEthernet0/0/0] quit / / return system view [Huawei] quit / / return user view [Huawei-GigabitEthernet0/0/0] return / / you can use this command or key combination Ctrl+z to return directly to the user view sysname aaa / / change the hostname

Get help, as shown in the figure:

Edit instructions, as shown in the figure:

History command query, as shown in the figure:

Query status information, as shown in the figure:

Configuration file management commands, as shown in the figure:

5. Remote management of network equipment

In this way, the cloud can be simulated with real devices:

The router needs to be configured as follows:

[Huawei] user-interface vty0 4amp / enter vty view [Huawei-ui-vty0-4] authentication-mode passwordPlease configure the login password (maximum length 16): 123456 authentication-mode passwordPlease configure the login password / set authentication mode to password, password 123456 [Huawei-ui-vty0-4] user privilege level 3amp / set user level to administrative level (0 is visitor level, 1 is monitoring level, 2 is configuration level, 3-15 is administrative level)

Remote telnet router succeeded!

For a remote switch, in addition to configuring the IP address for VLAN, you need to configure the following command:

[Huawei] user-interface vty0 4 [Huawei-ui-vty0-4] set authentication password simple 123456 password is 123456, password type is plaintext (simper), ciphertext (cipher) [Huawei-ui-vty0-4] user privilege level 3 [Huawei] undo info enableInfo: Information center is disabled.// cancel command echo information affects normal input

So much for a brief introduction to Huawei equipment commands!
