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

An AEP is required to deploy any VLAN pools on the leaf switches. It is possible to reuse the encapsulation pools (for example, VLAN) across different leaf switches. An AEP implicitly provides the scope of the VLAN pool (associated to the domain) to the physical infrastructure.

In the APIC GUI click on VM Networking and select the Policies sub-tab

Explanation;The ACI fabric decouples the tenant endpoint address, its identifier, from the location of the endpoint that is defined by its locator or VXLAN tunnel endpoint (VTEP) address. The following figure shows decoupled identity and location.

Cisco ACI fabric supports discovery, boot, inventory, and systems maintenance processes through Cisco APIC 

A bridge domain is a construct used to define a Layer 2 boundary within the fabric. A bridge domain can be viewed as somewhat similar to regular VLANs in a traditional switching environment.

• Specify a bridge domain in the private network.
• Specify the bridge domain name in the Name field (BD1).
• Click the + sign next to Subnets to add a public subnet (192.168.1.254/24) to associate with BD1. This public subnet will advertise to ISP1
