怎么更改機型配置python？

搭建，橋接，初始化配置。

給每臺路由器做好初始化配置，即配置修改設備默認名稱、配置管理IP地址、配置SSH及登錄用戶名和密碼。

以R2為例（小白，其他設備參考R2配置），修改設備名、配置IP地址：

[Huawei]SYS R2

[R2]

[R2]int g0/0/0

[R2-GigabitEthernet0/0/0]ip add 192.168.56.20 24

[R2-GigabitEthernet0/0/0]

[R2-GigabitEthernet0/0/0]qu

[R2]

以R2為例，配置SSH，其他設備參考如下即可：

[R2]rsa local-key-pair create

The key name will be: Host

% RSA keys defined for Host already exist.

Confirm to replace them? (y/n)[n]:y

The range of public key size is (512 ~ 2048).

NOTES: If the key modulus is greater than 512,

It will take a few minutes.

Input the bits in the modulus[default = 512]:2048

Generating keys...

.......+++

..............+++

.....++++++++

...............++++++++

[R2]user-interface vty 0 4

[R2-ui-vty0-4]authentication-mode aaa

[R2-ui-vty0-4]protocol inbound ssh

[R2]aaa

[R2-aaa]local-user along password cipher along123

[R2-aaa]local-user along privilege level 15

[R2-aaa]local-user along service-type ssh

[R2-aaa]ssh user along authentication-type password

[R2]

[R2]stelnet server enable

[R2]

上述配置完，建議用secureCRT先登錄一下各個設備，驗證網絡連通性、ssh連通性是否ok？

這里以R1為例，驗證一下。測試時，你們可以每臺都驗證一下。

這樣驗證的好處，假如待會我們寫的python腳本如果有問題，那跟網絡、ssh配置就沒關了，便于后續排錯就對啦！
