About the Basic GUI and the Advanced GUI
The Advanced Mode is the same GUI that has existed since 1.0 code. It represents a 1:1 mapping with the underlying object model. As of Cisco Policy Infrastructure Controller Release 1.2(1), there is now an option to utilize a Basic Mode. The Basic Mode intends to mask some of the complexity associated with Cisco Application Centric Infrastructure (ACI) constructs over the course of configuration. By doing so, the Basic Mode brings a set of limitations in what can and cannot be accomplished for configuration.
The main differences between the Advanced Mode and the Basic Mode are in the workflows that need to be performed to achieve the same configuration. For example, with the Basic Mode, you configure one port at a time, which means the GUI creates one object for each port. The Advanced Mode can be used to create multiple relationships with existing objects, where applicable, and do wholesale configurations using policies and profiles.
