Any idea which license is necessary for IBNS 2.0 on 3850 switches?

[Nadav]

I can't find anything in the IBNS documentation.

The newer IOS-XE versions have come up with the new style configs for Dot1x also called Identity-Based Network Service where we have to configure control class and control policy and use that control policy in the port configuration.

So it will use Base license as  Basic network access: AAA, IEEE-802.1X.

ps : rate if it helps!!!
