Switching to a new configuration

Procedure
  1. Back up the configuration using cfg-backup running-config config <config_name> command. In the following example, the configuration name used is "stable".
    cfg-backup running-config config stable
  2. Check the backup configuration using show config files command. 
    switch(config)# show config files

Configuration files:

id | act pri sec | name
---+-------------+--------
1  |  *   *   *  | config
2  |             | stable
3  |             |
4  |             |
5  |             |
  3. Change the running configuration as required, and backup the new configuration as "newfile".

    cfg-backup running-config config newfile 

    switch(config)# show config files

Configuration files:

 id | act pri sec | name
 ---+-------------+---------
  1 |  *   *   *  | config
  2 |             | stable
  3 |             | newfile
  4 |             |
  5 |             |
  4. Check the difference between the "newfile" (running configuration) and "stable" (backed up configuration) using cfg-restore flash stable diff command. Based on the difference, apply the backed-up configuration using cfg-restore flash stable command.
  5. Check the status of the configuration restore using show cfg-restore status command. 
    switch(config)# show cfg-restore status
