华为路由器配置文件备份与恢复

Posted 2021-02-06

首先物理机通过桥接和路由器AR1联通

配置AR1和AR2联通
[R1]inter g0/0/0
[R1-GigabitEthernet0/0/0]ip add 10.1.1.1 24

[R2]inter g0/0/0
[R2-GigabitEthernet0/0/0]ip add 10.1.1.2 24

[R2]ping 10.1.1.1
PING 10.1.1.1: 56 data bytes, press CTRL_C to break
Reply from 10.1.1.1: bytes=56 Sequence=1 ttl=255 time=90 ms
Reply from 10.1.1.1: bytes=56 Sequence=2 ttl=255 time=10 ms
Reply from 10.1.1.1: bytes=56 Sequence=3 ttl=255 time=20 ms
Reply from 10.1.1.1: bytes=56 Sequence=4 ttl=255 time=30 ms
Reply from 10.1.1.1: bytes=56 Sequence=5 ttl=255 time=20 ms

--- 10.1.1.1 ping statistics ---
5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 10/34/90 ms
在AR1上保存配置
<R1>save
The current configuration will be written to the device.
Are you sure to continue? (y/n)[n]:y
It will take several minutes to save configuration file, please wait..........
Configuration file had been saved successfully
Note: The configuration file will take effect after being activated
此时，我们将AR1的当前配置文件稍作修改
user-interface con 0
authentication-mode password
set authentication password cipher 123

我们可以通过compare比较当前配置文件和下次启动配置文件的区别
<R1>compare configuration
The current configuration is not the same as the next startup configuration file.
====== Current configuration line 53 ======
set authentication password cipher %$%$g!_Bi;XP*Nvly73KpfP,.4iiAa#,y/7W)wc8yM%CxQV.4l,%$%$`
user-interface vty 0 4
user-interface vty 16 20
====== Configuration file line 53 ======
user-interface vty 0 4
user-interface vty 16 20
#
wlan ac
#
return
对当前配置文件进行保存，并保存为config.cfg
<R1>save config.cfg
Are you sure to save the configuration to config.cfg? (y/n)[n]:y

<R1>dir

我们将R1配置为ftp server，并从客户端将配置文件config.cfg下载下来**
[R1]ftp server enable
aaa
local-user ftp password cipher ftp123
local-user ftp privilege level 15
local-user ftp ftp-directory flash:
local-user ftp service-type ftp
物理机登陆AR1

我们将路由器重启，不保存配置

<R1>reboot
Info: The system is comparing the configuration, please wait.
Warning: All the configuration will be saved to the next startup configuration. Continue ? [y/n]:n
System will reboot! Continue ? [y/n]:y
Info: system is rebooting ,please wait...

重启起来的AR1中并没有保存之前在console配置密码的配置

我们通过ftp，将拷贝下来的配置文件再次上传到AR1

并设置引导启动

不保存配置再次重启

起来后，查看console口配置，确认为config.cfg生效
