Temporary licenses
18
Date change restriction
Once the temporary license is installed, you cannot change the time of the switch until the
temporary license is removed. To change the time, you must remove the license, change the date,
and then re-install the license on the switch. However, if there is any other mechanism that exists to
change the time, such as NTP, then it is not blocked. 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.
Removing an expired license
The following procedure is disruptive to the switch.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the reboot command for the expiry to take affect.
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.
