This is very basic, so there is no need to mention the introduction.
Two authentication modes AAA and pasword
Topology:
Requirements:
R1 and R2 are interoperable
2. R1 is SSH service
3. R2 is telnet service
Summary
In short, the school curriculum is H3C, I have done both of them, and the commands are roughly the same.
首先配置IP
R1:
[Huawei-Ethernet0/0/0]ip add 10.1.1.1 24
R2:
[Huawei-Ethernet0/0/0]ip add 10.1.1.2 24
先配置R1上的ssh
//首先配置RSA密钥，1024
[R1]rsa local-key-pair create
The key name will be: R1_Host
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]:1024

[Huawei]stelnet server enable //华为和别的开始SSH的命令不同，注意
Info: Succeeded in starting the Stelnet server.
认证模式就AAA把，
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode aaa
[R1-ui-vty0-4]protocol inbound all //这一定要配置这条命令，我第一次没配置爆错，ALL 也可以改成别的服务
[R1]aaa
[R1-aaa]local-user admin password cipher admin888
[R1-aaa]local-user admin service-type ssh
//配置用户admin 服务为ssh
[R1-aaa]local-user admin privilege level 3
//给用户权限
[R1]ssh user admin authentication-type password //设置ssh用户
验证
R2配置Telnet 这里使用password密码认证:
[Huawei]telnet server enable
Info: The Telnet server has been enabled.
[Huawei]user-interface vty 0 4
[Huawei-ui-vty0-4]authentication-mode password
[Huawei-ui-vty0-4]set authentication password simple admin888
[Huawei-ui-vty0-4]protocol inbound all
验证
Summary: Two authentication modes
