New universal hardware switches include a Factory Default (Evaluation) License to use all features (excluding MACsec). This Evaluation license is equivalent to a Premier license. You can configure all features, except MACsec, without restrictions and save the configuration.
The evaluation period is 30 days. If after 30 days you have not obtained and installed a Premier license (see Obtaining and Installing Licenses) and you reboot the switch, the switch will effectively have only Base license (see Standard and Upgrade Licenses for Universal Hardware Switches) capabilities.
To extend the evaluation period, you can use the following commands:
To enable a trial license, issue the command debug epm enable trial-license.
To clear a trial license, issue the command debug epm clear trial-license. A reboot is required before the clear license takes effect.
Note
Enabling a newly obtained license requires clearing the trial license, and then rebooting the switch.
