Turns out naviseccli is not supported on VNXe and that the Unisphere CLI client (uemcli) should be used instead. 
First I need to confirm that VNXe supports the full naviseccli feature set.  Next I need to figure out how I can bypass or correct this error when I execute naviseccli against my VNXe3100:  Error occurred while trying to connect: Message: Invalid server certificate: certificate not trusted  Any help would be greatly appreciated.  Thanks.
