Huawei routers and CISCO router configuration differences

Shenzhen Huawei Company, as the current sets the nation's largest telecommunications equipment and data communications equipment manufacturers in recent years, its router products and technologies has made significant progress. Its production of high low-end Quidway routers, there is very broad product coverage, especially those in the low-end products relying on high cost-effective, comprehensive features and good compatibility, sharp increase in market share year after year, with CISCO and other imports product has become a rival trend.

Sichuan hung Huawei Technologies Co., Ltd. as a data communication products in the country's agents, in the installation and testing of their products during a certain amount of technical experience gained in this exchange with colleagues.

Huawei routers with the same grade in the functional properties of CISCO routers and configuration of the interface is fully consistent with some aspects is also in accordance with domestic needs of users had a good improvement. For example, Chinese and English can be switched configuration and debugging interface to enable Chinese users no longer have to face a lot of English words but not from the start with a professional. In addition to its software upgrade, remote configuration, backup center, PPP callback, router, hot backup, etc. For users, are very useful features.

In the configuration, the Huawei router, the previous software version (VRP1.0-the equivalent of CISCO's IOS) and CISCO have subtle differences, but the current version (VRP1.1) has been, and is compatible with CISCO, the following first introduced the VRP the software upgrade method, and then gives the instructions on the configuration.

The following elements need to reply to see the

1, VRP software upgrade operations

the user should be aware of before upgrading your router's hardware configuration and the corresponding software bootrom version of the guide, as it relates to the possibility of upgrades and upgrades, or upgrade failure would cause the router can not run. In this we upgrade to VRP1.1 from VRP1.0 example shows the method to upgrade.

1. Router configuration cable at one end and the PC-side with the router's console serial port to connect

2. In the win95/98 the use of direct connections established under the super-terminal, the parameters are as follows: quote: </P “Baud Rate 9600, Data bits 8, stop bits 1, invalid inspection, no flow control, VT100 terminal type 3. HyperTerminal on-line and opened the router, power supply, will appear on the screen guide information, in the event of: quote:

PressCtrl-BtoenterBootMenu. when, within three seconds press the Ctrl + b, reference will be prompted to enter the password:

PleaseinputBootrompassword: The default password is blank, directly enter into the boot menu BootMenu, select one of the menu, that is, VRP software upgrade Downloadapplicationprogram , followed by the screen prompts to select the download baud rate, we generally select 38400bps, then see a message: quote:

Downloadspeedis38400bps.Pleasechangetheterminal 'sspeedto38400bps, andselectXMODEMprotocol.PressENTERkeywhenready. this time into a super terminal attributes, modify the baud rate is 38400, revised HyperTerminal connection should be disconnected, and then enter the connection state, so that the onset of new properties, followed by on-screen instructions: quote:

Downloading … CCC This means that the router has entered a state of waiting to receive the file, we can choose a super function of the terminal to send the file, select the corresponding VRP software file name, communication protocol selection Xmodem, after the HyperTerminal automatically send files to the router, the entire transmission process took about eight and a half minutes. After the completion prompt message appears, the system will be received by VRP software written FlashMemory cover the original system, this time the entire upgrade process is completed, the system prompts to change the baud rate back to the HyperTerminal: References:

Restoretheterminal'sspeedto9600bps .

PressENTERkeywhenready. modify exhausted to remember to disconnect and connect the HyperTerminal properties of operation of the new onset, followed by the router software, started, with showver command will see the corresponding version information.

The following is interoperable with CISCO should pay attention to:

2, in the default package on the difference between link layer (mainly for DDN configuration)

1. Huawei VRP1.0 and the previous version, in the configuration, because of CISCO default link layer encapsulation format is HDLC, while Huawei router's default link layer encapsulation format for PPP, so in order to be able to communicate, you need to CISCO router's PPP encapsulation format to format, that is, using the command: quote:

encapsulationPPP 2. Huawei VRP1.1 and subsequent versions, an increase of HDLC Encapsulation Format. In this way, do not need to change CISCO package format, but will Huawei router package format can be changed to HDLC encapsulation format, using the command: quote:

encapsulationhdlc

3, the difference in the configuration on the X.25

1. Huawei VRP1.0 and earlier versions of the configuration, CISCO's X25 as the default package format for its own standards. Huawei router package format as an international standard IETF, so in order to be able to communicate, you need to CISCO router ietf encapsulation format to format, that is, use the command: quote:

encapsulationx25ietf 2. Huawei VRP1.1 and subsequent versions of , specifically an increase of packaging formats compatible with CISCO. In this way, do not need to change CISCO package format, but will the X25 package format for Huawei Router CISCO compatible package format can be changed, that is, use the command: quote:

encapsulationx25cisco

4, in the configuration Frame Relay ( Frame-Relay) on the difference

1. Huawei VRP1.0 its previous version, due to the default FR package CISCO format CISCO's own standards; while Huawei router package format as an international standard IETF. In addition, since the LMI (Frame Relay Local Management information) type of configuration, CISCO default is to use its own format, while Huawei routers using international standards Q.933a format, so in order to be able to communicate, you need to CISCO Router The FR package format, replaced by IETF, the LMI can be changed Q.933a format interoperability, that is, use the command: quote:

encapsulationframe-realyietf

frame-realylmi-typeq933a 2. Huawei VRP1.1 and Beyond version, specifically an increase of CISCO compatible with the FR package formats, as well as the LMI format. In this way, do not need to change CISCO package, but simply Huawei routers FR encapsulation format and the LMI type to CISCO compatible format can be, that is, use the command: quote:

encapsulationframe-relaycisco

frame-relaylmi -typecisco

above, is the interconnection between Huawei and CISCO attention should be paid, if the user's link CISCO than international standards for packaging but its own format, but they do not want users to modify configuration CISCO, then the Huawei end must be changed accordingly.
