Configuration restore with force option

Prerequisites

Back up the configuration using traditional copy config or cfg-backup commands.

Procedure

Execute the show config files command. By default, the config file provides all the associations.

switch(config)# show config files

Configuration files:

 id | act pri sec | name
 ---+-------------+-------
  1 |  *   *   *  | config
  2 |             | file1
  3 |             | file2
  4 |             |
  5 |             |

Use cfg-restore flash file1 force command to see the configuration of file1.

switch(config)# cfg-restore flash file1 force

As the file1 configuration requires a reboot, a system reboot occurs. When the switch comes up, file1 is the new active configuration.

switch(config)# sh config files

Configuration files:

 id | act pri sec | name
 ---+-------------+---------
  1 |      *   *  | config
  2 |  *          | file1
  3 |             | file2
  4 |             |
  5 |             |

NOTE:

During a configuration restore with reboot, the association changes. To make the configuration as a default configuration for subsequent system reboots, use startup-default [<primary|secondary>] config FILENAME command.

For startup-default config file1:

switch(config)# show config files

Configuration files:

id | act pri sec | name
 --+-------------+---------
 1 |             | config
 2 |  *   *   *  | file1
 3 |             | file2
 4 |             |
 5 |             |
