Viewing, applying, reverting, and saving changes
As you use the configuration menus to set switch parameters, the changes you make do not take effect
immediately. All changes are considered pending until you explicitly apply them. Also, any changes
are lost the next time the switch boots unless the changes are explicitly saved.
While configuration changes are in the pending state, you can:
• View the pending changes
• Apply the pending changes
• Revert to restore configuration parameters set with the last apply command
• Save the changes to flash memory
Viewing pending changes
You can view all pending configuration changes by entering diff at any CLI prompt:
# diff
You can view all pending configuration changes that have been applied but not saved to flash
memory by entering diff flash at any CLI prompt:
# diff flash
Applying pending changes
To make your configuration changes active, you must apply them. To apply configuration changes,
enter the following command at any prompt:
# apply
NOTE: All configuration changes take effect immediately when applied.
Reverting changes
The revert command removes configuration changes that have been made, but not applied. Enter
revert apply to remove all changes that have not been saved:
# revert
