Is Unified Border Element licensing enforced on the 2900 and 3900 ISRs? If so, what command can I use to determine how many sessions my VGs are licensed for? A show version just says I have the UC license.
CUBE licensing ("allow connections...." CLI) is not yet enforced (all honor-based at this time) although it will become so in future. For demo purposes an
eval license is required, and for production environments a CUBE license (FL-CUBE-XX) has to be ordered. All paper based and nothing to installl as such.
If u configure GK as well, u'd need to purchase and install GK license though.
CUBE is a RTU license and does not use a key. All you need to have is the UC license installed on the router to configure it.
