cisco 设备配置文件的保存和恢复

cisco 配置文件的保存和恢复

记录cisco交换机设备配置文件的保存与恢复，附加h3c设备的操作命令，华为网络设备与h3c类似。

保存配置文件

思科保存配置文件目录结构大概如下：

R1#dir
Directory of nvram:/

  508  -rw-        2190                    <no date>  startup-config
  509  ----          24                         <no date>  private-config
  510  -rw-        2190                    <no date>  underlying-config
    1  ----             34                         <no date>  persistent-data
    2  -rw-           4                          <no date>  rf_cold_starts
    3  -rw-           0                         <no date>  ifIndex-table

启动配置文件为start-config

要保存当前配置文件的逻辑是先备份当前的启动文件startup-config

R1#copy startup-config nvram:20190826.backup
Destination filename [20190826.backup]? 

2190 bytes copied in 1.136 secs (1928 bytes/sec)

保存的配置文件如下：

R1#dir
Directory of nvram:/

  508  -rw-        2190                    <no date>  startup-config
  509  ----          24                         <no date>  private-config
  510  -rw-        2190                    <no date>  underlying-config
    1  ----             34                         <no date>  persistent-data
    2  -rw-           4                           <no date>  rf_cold_starts
    3  -rw-           0                           <no date>  ifIndex-table
    4  -rw-           2190                    <no date>  20190826.backup

522232 bytes total (513822 bytes free)

将当前配置保存为启动配置

R1#copy running-config nvram:startup-config
Destination filename [startup-config]?
Building configuration...
[OK]

恢复配置文件

例如恢复到20190826的配置

R1#copy nvram:/20190826.backup startup-config
Destination filename [startup-config]? y

2190 bytes copied in 1.108 secs (1977 bytes/sec)

重启交换机，不需要保存运行中的配置：

R1#reload 
Proceed with reload? [confirm]y
*Jul 27 02:14:18.199: %SYS-5-RELOAD: Reload requested by console. Reload Reason: Reload Command.

                ROM: reload requested...

H3C 化为的操作思路

保存文件，选用配置

<F1070>save 20190828.cfg
The current configuration will be saved to flash:/20190828.cfg. Continue? [Y/N]:y
Now saving current configuration to the device.
Saving configuration flash:/20190828.cfg.Please wait...
Configuration is saved to device successfully.

配置启动项：

<F1070>startup saved-configuration 20190828.cfg 
Please wait...... Done.
