IOS Licenses Evaluation vs. Permanent

[Erik T.]

I got a Cisco IR809G-LTE-GA-K9 on my desk, trying to figure out the licenses.

Will the licenses keep working/beeing active until the device dies, or will they become inive after an evaluation period. ?

Technology Package License Information for Module:'ir800'

------------------------------------------------------------------------
Technology    Technology-package                  Technology-package
              Current              Type           Next reboot
------------------------------------------------------------------------
ipbase        ipbasek9             Permanent      ipbasek9
security      securityk9           Permanent      securityk9
data          datak9               Permanent      datak9

All licenses are of type 'Permanent', so i guess they stay active for the life time of the device, or ?

Running #show license feature

Feature name             Enforcement  Evaluation  Subscription   Enabled  RightToUse
ipbasek9                 no           no          no             yes      no
securityk9               yes          yes         no             yes      yes
datak9                   yes          yes         no             yes      yes

Now 'securityk9' and 'datak9' are marked as 'Evaluation'

Finally running #show license

So security and data licenses expire in 8 weeks and 4 days from now ?
Or what is the reason for the output of '#show license detail' ??

Thanks in advance.
