Rolling Back to a Previous Configuration

All switch configurations reside in the internal bootflash: file system. If your internal bootflash: file system is corrupted, you could potentially lose your configuration. Save and back up your configuration file periodically.

•This example shows how to roll back to a snapshot copy of a previously saved running configuration (binary file):

switch# copy bootflash:snapshot-config bootflash:startup-config

Note You can enter a rollback command only when a snapshot is already created. Otherwise, you will receive the No snapshot-config found error message.

•This example shows how to roll back to a configuration copy that was previously saved in the bootflash: file system (ASCII file):

switch# copy bootflash:my-config startup-config

Note Each time a copy running-configstartup-configcommand is entered, a binary file is created and the ASCII file is updated. A valid binary configuration file reduces the overall boot time significantly. A binary file cannot be uploaded, but its contents can be used to overwrite the existing startup configuration. The write erase command clears the binary file.

Deleting Files

Assuming you are already in the bootflash: file system, use the delete command to delete a file from the

bootflash: file system:

switch# delete dns_config.cfg
