在已经出现配置命令误删或者错误配置时,可以按以下的步骤进行配置的快速回滚:

1.  确认配置命令误删或者错误配置的提交节点的Commit ID:

执行命令:display  configuration commit changes

< ShenZhen-DC1-Core-CE12816>display  configuration commit changes

Building configuration

Commit changes of commitId 1000000108

  #

+ ospf 100 router-id 1.1.1.1

+  area 0.0.0.0

+   network 114.172.12.2 0.0.0.0

  #

Commit changes of commitId 1000000107

  #

+ interface LoopBack0

+  ip address 1.1.1.1 255.255.255.255

  # 

Commit changes of commitId 1000000106 //假设从本次commit后的操作都是要恢复的

  #

- sysname HUAWEI

  #

+ sysname ShenZhen-DC1-Core-CE12816

  # 

2.  执行rollback configuration to commit-id XXX

 < ShenZhen-DC1-Core-CE12816>rollback configuration to commit-id 1000000106

Warning: This operation will revert configuration changes to the previous status

. Continue? [Y/N]:y

Loading rollback changes

Committing

Check rollback result

Configuration rollback succeeded.

Please use 'display configuration commit changes last 1' to view the changes.

 3.使用display configuration commit changes last 1,检查是否回滚到操作前的配置状态: 

< ShenZhen-DC1-Core-CE12816>display configuration commit changes last 1

Building configuration

  #

- interface LoopBack0 //“-”表示在本次恢复过程中删除的命令

-  ip address 1.1.1.1 255.255.255.255

  #

- ospf 100 router-id 1.1.1.1

-  area 0.0.0.0

-   network 114.172.12.2 0.0.0.0

  # 

如果误操作是通过最近1次commit命令提交生效的,也可以通过以下命令进行快速回退,以节省时间:

1.   执行rollback configuration last 1:

< ShenZhen-DC1-Core-CE12816>rollback configuration last 1

Warning: This operation will revert configuration changes to the previous status

. Continue? [Y/N]:y

Loading rollback changes

Committing

Check rollback result

Configuration rollback succeeded.

Please use 'display configuration commit changes last 1' to view the changes. 

2.执行display configuration commit changes last 1检查恢复后的配置
