Rolling Back to a Previous Configuration

Problems, such as memory corruption, can occur that make it necessary for you to recover your configuration
from a backed up version.
Each time that you enter a copy running-config startup-config command, a binary file is created and
Note
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.
SUMMARY STEPS
1. write erase
2. reload
3. copy configuration_file running-configuration
4. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1
write erase
Example:
switch# write erase
Step 2 reload
Example:
switch# reload
OL-29291-02
Purpose
Copies the startup-configuration file to internal memory.
The filesystem, directory, and filename arguments are case
sensitive.
Purpose
Clears the current configuration of the switch.
Restarts the device. You will be prompted to provide a kickstart and
system image file for the device to boot and run.
By default, the reload command reloads the device from a
Note
binary version of the startup configuration.
Beginning with Cisco NX-OS 6.2(2), you can use the reload
ascii command to copy an ASCII version of the configuration
to the start up configuration when reloading the device.
