To implement a physical connection in ACI, first define the following:
• Domain – Defines what you want to connect (bare-metal server or switch, router, virtual environment, etc.).
• VLAN/VSAN Pool – Defines which VLANs or VSANs this connection will use.
• AEP – Groups the Domain(s) you need to allow through a specific port and their corresponding VLANs/VSANs.
• Interface Profile – The interface for this connection.
• Interface Policy Group – The set of policies applied to an interface.
• Interface Policies – The actual policies (e.g. cdp, lldp, link speed, AEP, etc.) for this connection.
• Switch Profile – The Switch/Node for this connection.
