Universal Time-based licenses

Removing an expired license

CAUTION

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 Time-based licenses

Universal Time-based licenses behave the same way as the Time-based temporary licenses

supported in prior Fabric OS versions. Prior to Fabric OS v6.3.0 release, when a Time-based

temporary license for a feature expires, the general policy is to allow the feature to continue

working while generating warning messages until the switch is either reset or a CP failover occurs,

at which time the feature will no longer work. When an expired license is replaced with a new

license (permanent, or another time-based license) the warning messages cease (if no

reset/failover has already happened since expiration) and, if a reset/failover has happened, the

feature will work again. This behavior is also applicable to Universal Time-based Licenses.

Universal Time-based license expiration date

Unlike prior temporary licenses that have a specific expiration date encoded in them, Universal

Time-based 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 Time-based 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 that the Universal Time-based license is valid for. Universal Time-based licenses cannot be

removed and reinstallation of the same Universal Time-based license on the same switch is not

permitted.

Extending a license

Extending a Universal Time-based license is done by adding a temporary license with expiry date

after the Universal Time-based license expiry date, or by adding a permanent license. Re-applying

an existing Universal Time-based license is not allowed.

Deleting a license

Universal Time-based licenses are always retained in the license database on the product even

though they can be explicitly deleted from any user interface.
