Hi,
A temporary software license is limited to a usage period. After the usage period expires, the switch continues to use the temporary software license until it is restarted. Before it restarts, warning messages state the switch is running the feature set without a valid license. After the switch restarts, the switch uses a valid software license based on the previously described hierarchy. If the switch does not have a valid license, it uses the IP base software license.
Here is the link that you could use to request for a temporary license:

++ The software licenses are not affected by Cisco IOS software upgrades.
++ A software license applies only to a specific feature set.
++ A switch can have more than one software license, but you can enable only one license at a time.
Removing Software Licenses Using CLI:
================================
++ In software releases earlier than Cisco IOS Release 12.2(46)SE, you have the license clear license-level [switch switch-num] privileged EXEC command.
++ Use the license-level parameter to specify the software license to remove. Use the switch switch-num parameter to specify the stack member. The switch switch-num option is supported only on Catalyst 3750-E switches.
In Cisco IOS Release 12.2(46)SE or later, if the software license is in use (active):
++ Enter the “license boot level license-level” global configuration command to specify a license level different from the current one.
++ Restart the switch to enable new software license.
++ Enter the license clear license-level [switch switch-num] privileged EXEC command to remove previous software license.
