Huawei 3COM router differs from Cisco configuration

Huawei router and the same class Cisco router in the functional characteristics and configuration interface is completely consistent, some aspects also according to the needs of domestic users made a good improvement. For example, in English and Chinese can be switched configuration and debugging interface, so that users do not have to face a large pile of English words and do not start.

In addition its software upgrades, remote configuration, backup center, P <――element not supported-type:8 Name: #comment ――&GT;PPP callback, router hot backup, etc., are very useful for users of functional characteristics.

In terms of configuration, the previous software versions of Huawei 3COM routers (vrp1.0-equivalent to Cisco's iOS) are slightly different from Cisco's, but the current version (VRP1.1) is compatible with Cisco, the following is the first introduction to the VRP software upgrade method, and then the configuration instructions.

First, VRP software upgrade operation

Before you upgrade, users should understand the hardware configuration of their routers and the version of the corresponding boot software bootrom, because this is about whether you can upgrade and upgrade the method, or the failure of the upgrade will cause the router not to run. Here we use the upgrade from VRP1.0 to VRP1.1 as an example of how to upgrade.

1. Router configuration cable one end and the PC serial port with the router's console port connection

2. To establish the use of direct-connected HyperTerminal under WIN95/98, the parameters are as follows:

Baud rate 9600, data bit 8, stop bit 1, invalid test, no flow control, VT100 terminal type

3. The super terminal connects the machine to turn on the router power supply, the screen will appear the guidance information, in appears:

Press Ctrl-b to enter Boot Menu.

When you press Ctrl+b in three seconds, you will be prompted to enter your password

Please input bootrom password:

The default password is empty, direct enter into the boot menu boot menus, select 1 under the menu, that is, download application program Upgrade VRP software, after the screen prompted to choose the download baud rate, we generally choose 38400 bps, then appear prompted message:

Download speed is 38400 bps. Please change the terminal ' s speed to 38400 Bps,and Select XMODEM protocol. Press ENTER key when ready.

At this point into the HyperTerminal "properties", modify the baud rate of 38400, after the modification should be disconnected HyperTerminal, and then enter the connection state, so that the new properties of the effect, after the screen prompts:

Downloading ... Ccc

This means that the router has entered the status of waiting to receive files, we can choose the HyperTerminal file "Send" function, select the appropriate VRP software file name, the communication protocol selected Xmodem, after the super terminal automatically send files to the router, the entire transmission process is about 8.5 time consuming. When the message appears, the system will receive the VRP software written to the flash memory overwrite the original system, at this time the entire upgrade process is complete, system prompts to change back to the HyperTerminal baud rate:

Restore The terminal ' s speed to 9600 bps.

Press ENTER key when ready.

Remember to perform a HyperTerminal disconnect and connect operation to make the new properties work, then the router software starts, and the show ver command will see the appropriate version information.

Here's what you should be aware of when interacting with Cisco:

Second, the difference in the default link layer package (mainly for DDN configuration)

1. Huawei VRP1.0 and its previous version, when configured, because Cisco's default link Layer package format is HDLC, and Huawei Router's default link layer package format is PPP, so in order to be interoperable, the Cisco router's encapsulation format needs to be changed to PPP format, that is, use the command:

Encapsulation PPP

2. Huawei VRP1.1 and its later version, added the HDLC package format. In this way, you do not need to change the package format for Cisco, but instead change the package format of the Huawei router to the HDLC package format, that is, use the command:

Encapsulation HDLC
