I have a spare 4331 router (ISR4331/K9) with version 16.6.4 which I plan to use as my CUBE and I plan to upgrade IOS to the version 17.2.1r to use it with Microsoft phone system for external calls.
The license information on this router is as below:
Router01#sh license feature
Feature name Enforcement Evaluation Subscription Enabled RightToUse
appxk9 yes yes no yes yes
uck9 yes yes no yes yes
securityk9 yes yes no yes yes
ipbasek9 no no no no no
FoundationSuiteK9 yes yes no no yes
AdvUCSuiteK9 yes yes no no yes
cme-srst yes yes no no yes
hseck9 yes no no no no
throughput yes yes no no yes
internal_service yes no no no no
Router01#sh license detail uck9
Index: 1 Feature: uck9 Version: 1.0
License Type: RightToUse
License State: Active, In Use
License Count: Non-Counted
License Priority: Low
Store Index: 1
Store Name: Built-In License Storage
The appxk9 and securityk9 on this router are permanent.
1. Do I need to purchase the technology pack for uck9 and install it to make it permanent?
2. Is it allowed to use it as RightToUse without making it permanent? I will be connecting this router to CSSM for using the CUBE session licenses.
Thanks and regards,
