Emergency Restore of the boot.cfg File
If all copies of the boot.cfg file have been deleted and a system boot has occurred, network configuration
information is permanently lost. However, if the files have been deleted and no boot has occurred you can
issue a write memory command to regenerate the boot.cfg file.
Can I Restore the boot.file While Running from Certified?
Yes. While it is not recommended that you routinely save configuration changes while running from the
certified directory, you can perform an emergency restore of your configuration by following the steps:
1 Copy your current configuration to a manually-generated boot.cfg file in the /flash directory by enter-
ing the following command:
-> configuration snapshot all boot.cfg
2 Copy the new boot.cfg file from the /flash directory to the /flash/working directory using the cp
command. For example:
-> cp boot.cfg working/boot.cfg
3 Reboot the switch from the /flash/working directory by entering the following command:
-> reload working no rollback-timeout
Once the boot.cfg file is confirmed to be good, it needs to be saved to the certified directory using the
procedure described in “Copying the Working Directory to the Certified Directory” on page 4-20.
