PI 3.2 Does Not list StackSub-st Interfaces on 3850 after IOS Upgrade

[Ric Hernandez]

I recently upgraded 2 switch stacks in our Chicago office to 3.6.6E from 3.6.4E.  After that upgrade, PI 3.2 does not list the stacksub-st- interfaces for those 2 switch stacks.  It does list the stackport1, stackport2, etc...  On Switch stacks running 3.6.4 or lower, it shows both Stackport1 and stacksub-st-1-1 interfaces.  Has anyone run across this?

Upgrading to 3.7.5 fixed the issue.  There's a bug on the 3.6.X train on that addresses this. CSCve73570.
