I. the past life and present life of H3C

The predecessor of H3C, Huawei 3COM, is a joint venture between Huawei and 3COM of the United States (it is rumored that Cisco sued Huawei for plagiarism, so Huawei found a strong and well-connected company in the United States to prove that it was not plagiarized, which is 3COM). In 2006, Huawei sold its 49 per cent stake in Huawei's 3COM to 3COM for $880 million. In 2007, the company officially changed its name to "Hangzhou Huasan Communication Technology Co., Ltd.", referred to as "H3C".

At present, the data communication market is mainly divided into telecom operators and enterprise network market. Huawei has been focused on the operator market, while H3C mainly focuses on the enterprise network market. CISCO's business spans the operator and enterprise network markets, and maintains a leading position in these two markets. Huawei is the main competitor to cisco in the operator market, while H3C is the main competitor to cisco in the enterprise network market. Cisco has advantages in energy, finance, international enterprises, power and other industries, while H3C has advantages in government, tobacco, transportation, small and medium-sized enterprises and related government procurement. In the field of routers and switches in China, H3C has ranked first in market share.

Relying on the deep accumulation in the field of ip technology, H3C's product system mainly includes: ip network products, ip wireless products, ip security products, ip storage products, ip multimedia products, ip management products and training products. The following is a brief description of the routing and switching products that are included in ip network products.

1. Routing series products

H3C's router product line has many similarities with cisco routers, and its main product lines are also developed for users of different network sizes, such as ER (enterprise router, enterprise router) for small businesses, MSR (multiple services router, multiservice router) for medium-sized enterprises, and SR (service router, service router) for large enterprises and operators. The specific models are as follows:

The corresponding application environment and main functions are as follows:

ER series routers: mainly used for small and medium-sized enterprises broadband access low-end router series, mainly located with Ethernet, optical fiber and adsl wan access to the SMB market and the government, enterprise institutions, Internet cafes and other network environment, such as Internet cafes, enterprises, schools and hotels that need high-speed internet broadband.

MSR series routers: it is a series of mid-range routers mainly used in large and medium-sized enterprises and branch offices of group companies. This series of routers integrates data, voice, security, switching and user open services, and is a truly integrated multi-service router product. This is the most widely used family of routers in the enterprise, equivalent to Cisco's ISR series routers.

SR series routers: it is a series of 10 Gigabit high-end routers mainly used in large enterprises or some industry users, such as telecommunications, power, finance, education, government agencies and so on. Among them, it is divided into two parts according to the target users, SR6600 series routers are launched for large enterprises, and users with small network size and low application needs, such as finance, education, government agencies, etc., while SR8800 series routers are launched for operators'IP backbone network, metropolitan area network and the core and convergence location of various large IP networks. 2. Exchange series products

H3C Ethernet switch product line is often complete, from campus to data center, from 100000 to 100 megabytes, from high-end to low-end, and from core layer to access layer, which can flexibly meet the needs of users at different levels. Among them, the core layer is basically routed switches with strong routing functions, such as S10500, S9500E, S7500E, S7500, etc.; in the aggregation layer, there are mainly all-gigabit intelligent switches, and the representative series mainly include S5500-EI/SI, S5510, S5120-EI/SI, S5600 and so on. In the access layer, the uplink basically supports Gigabit Ethernet technology, and the downlink is basically 100 megabytes. The main representative series and models are S3100-EI/SI, S3600-EI/SI, S3610, E328, E126 and so on. SMB switch refers to the series of switches used in small and medium-sized enterprises. The representative series and models are S1000Compact 1200, S1500Compact E, S1650, S2100, S5000P, S5000E and so on. The products of the switching series are as follows:

In addition to providing a full range of campus Ethernet switch products for the vast number of campus and enterprise users, H3C also provides switch products specially developed for data centers for large and medium-sized enterprises or Internet enterprises. Because the scale of the data center is generally small, it is mainly used for Internet or database management, and it is not easy for ordinary switches to be competent. Some larger data center network aggregation layer can also choose the switch of the core layer, after all, this kind of network has very high requirements for equipment data processing performance and other aspects. The specific products are as follows:

II. Basic configuration of H3C

There's a lot of talk about it, so let's take a look at some basic configurations about H3C.

The basic configuration of H3C includes interface configuration, Telnet access, static routing, ACL, VLAN and Trunk and NAT (in fact, it is the same as Huawei's equipment).

1. Interface configuration: system-view / / enter privileged mode [h4c] interface ethernet0/0/0 / / enter interface [h4c-ethernet0/0/0] ip address 192.168.10.1 255.255.255.0 / / configure interface ip address [h4ct-ethernet0/0/0] undo shutdown / / enable interface, and enable [h4c-ethernet0/0/0] description to LAN / / interface description by default Optional configuration [h4c-ethernet0/0/0] quit / / exit 2, Configure Telnet access: [H4C] telnet server enable / / enable [H4C] local-user admin / / create user admin [h4c-luser-admin] password cipher 2019.com / / configure password [h4c-luser-admin] service-type telnet / / specify server type as telnet [h4c-luser-admin] authorization-attribute level 3 / / specify command level 3 [h4c-luser-admin] quit [h4ct] user-interface vty0 / / enter vty line [h4c-ui-vty0] authentication-mode scheme / / configure user authentication method [h4c-ui-vty0] protocol inbound telnet / / support telnet [h4c-ui-vty0] quit3, Configure static route: [h4c] ip rout-static 172.16.0.0 255.255.0.0 192.168.1.2 / configure static route [h4c] ip route-static 0.0.0.0 0.0.0 200.0.0.2 / / configure default route 4, Configure vlan and Trunk: [SW] VLAN 2 / / create vlan2 [sw-valn2] name caiwu / / configure vlan2 name [sw-vlan2] port e1par 0pact 3 to e1qp0xt 4 / / add the port to Vlan5 [sw-ethernet1/0/5] port access vlan2 [sw-ethernet1/0/5] quit [sw] interface e1qq0q1 [sw-ethernet1/0/1] port link-type. Trunk / / specifies that the interface is trunk mode [sw-ethernet1/0/1] port trunk permit vlan all / / allows all vlan to pass through the trunk interface [sw-ethernet1/0/1] quit5, Configure ACL:

H3C ACL is divided into two categories: basic (standard) and advanced (extension): basic is the basic acl number 2000-2999, the source address control, advanced is the advanced acl, number 3000-3999

The command is as follows:

Acl advanced 3000 / / create an advanced ACLrule 0 permit ip source 192.168.3.0 0.0.0.255 destination any// to allow the source address 3.0 network segment to go to any destination address 6, configure NAT:

NAT is mainly divided into the following two categories:

Easy_ip (PAT): directly uses the ip address of the interface as the source address of the translated message.

Nat_server (static PAT): maps an external address port to an internal server port.

The relevant commands are as follows:

Configuration of easy_ip:

Acl basic 2001

Rule 5 permit source 192.168.2.0 255.255.255.0

Int g0/0

Ip add 202.202.202.2 255.255.255.0

Undo shutdown

Nat outbound 2001

Configuration of nat_server:

Int g0/1

Nat server protocol tcp global 200.200.200.3 80 inside 192.168.3.250 80
