ACI (Application Centric Infrastructure) is a Cisco data center architecture that provides a holistic view of the infrastructure, allowing for network automation, centralized management, and policy-based network provisioning. ACI utilizes the concept of Application Network Profiles (ANPs) to define policies that are associated with specific applications. An ANP is a collection of EPGs (Endpoint Groups) that define the endpoints that belong to an application.

To classify an endpoint into an application EPG, there are two criteria that can be used statically:

  1. VM name: A virtual machine (VM) is an operating system or application environment that is installed on a hypervisor. In a virtualized environment, VMs can be created, moved, and deleted dynamically. VM name is a unique identifier for a VM, and it can be used to statically classify endpoints into an application EPG.

  2. Physical leaf port: ACI fabric consists of spine switches and leaf switches that connect to the endpoints. A physical leaf port is a physical interface on the leaf switch that is connected to an endpoint. By statically mapping endpoints to physical leaf ports, they can be classified into an application EPG.

The other options listed in the question are not criteria that can be used to classify endpoints statically into an application EPG:

  • Guest operating system: The guest operating system is not a unique identifier for an endpoint and cannot be used to classify it into an application EPG.
  • DNS host name: The DNS host name is a hostname assigned to an IP address, but it is not a unique identifier for an endpoint and cannot be used to classify it into an application EPG.
  • VLAN: A VLAN is a logical network that separates traffic within a physical network. While VLANs can be used to segment traffic, they are not unique identifiers for endpoints and cannot be used to classify them into an application EPG.
