CAUTION
If you are using NTP to synchronize the time between your network devices, including switches
or Backbones, then do not attempt to change the system date and time when a temporary
license is installed.
Configupload and download considerations
The configDownload and configUpload commands download the legacy, enhanced, consumed
capacities, and temporary licenses.
Expired licenses
Once a temporary license has expired, you can view it through the licenseShow command. Expired
licenses have an output string of "License has expired". RASlog warning messages are generated
every hour for licenses present in the database which have expired or are going to expire in the next
five days. An expired license may become unusable after a reboot, failover, firmware download, or a
port or switch disable or enable operation.
Universal temporary licenses
Universal temporary license keys include a duration period. Once installed on a switch, an expiration
date is calculated and the duration is decremented until there is no remaining time, at which point it is
expired. Because of this, universal temporary licenses should not be installed on a switch until you are
ready to use or test the feature, so as not to unnecessarily consume a portion of the temporary-use
duration.
The expiration date is based on the system time at the installation of the license plus the number of
days for which the universal temporary license is valid. Universal temporary licenses cannot be
removed and reinstalled on the same switch.
Universal temporary licenses are always retained in the license database on the product even though
they can be explicitly deleted from any user interface.
Extending a universal temporary license
Extending a universal temporary license is done by adding a temporary license with an expiry date
after the universal temporary license expiry date, or by adding a permanent license. Re-applying an
existing universal temporary license is not allowed.
Universal temporary license shelf life
All universal temporary licenses are encoded with a "shelf life" expiration date. Once this date is
reached, the temporary licensed feature can no longer be used on the switch.
