Explanation:
In ACI, the logic to define a virtual Port-Channel is as follows:
The infrastructure administrator creates the VPC domain from the "Access Policies" as "protection" policy (i.e. which "nodes" are part of a vPC domain)
The infrastructure administrator defines the "Access Policy Group" "Bundle Interfaces" where one creates the specific vPC channel-group configuration
The interface policy defines a list of interfaces that are associated with the vPC channel- group but it doesn't specify which leafs this is associated with
The switch policy defines a list of "nodes" nodes whose interfaces selected by the interface policy are defined as part of the vPC
