Chapter 4 Managing Licenses
Backing Up License Files
Backing Up License Files
All installed license files can be backed up as a .tar file in the user specified location. Use the copy
licenses command in EXEC mode to save your license file to one of two locations; bootflash: or volatile:.
The following example saves all licenses to a file named Enterprise.tar:
switch# copy licenses bootflash:/Enterprise.tar
Backing up license done
Tip We recommend backing up your license files immediately after installing them and just before running
a write erase command.
Caution If you erase any existing licenses, you can only install them using the install license command.
Identifying License Features in Use
When a Cisco NX-OS software feature is enabled, it can activate a license grace period. To identify the
features active for a specific license, use the show license usage license-name command.
switch# show license usage FC_FEATURES_PKG

Uninstalling Licenses
You can only uninstall a permanent license that is not in use. If you try to delete a permanent license that
is currently being used, the software rejects the request with an error message. Uninstalling an unused
license initiates the grace period. The grace period is measured from the first use of the feature without
a license and is reset when a valid license file is installed.
Note Permanent licenses cannot be uninstalled if they are currently being used. Features turned on by
permanent licenses must first be disabled, before that license is uninstalled.
