Description (partial)

There may be an inconsistency between the FEX front-panel port (HIF) running configuration and the VPC consistency-parameters after upgrading a N9K switch in a dual-homed (Active-Active, AA) FEX setup.
The FEX HIF is configured with the command "spanning-tree port type edge" but VPC reports the interface as "default".

Issue is seen when N9K switch is (disruptively) upgraded to 7.0(3)I7(x)
