An engineer must add a group of 70 bare-metal ESXi servers to the Cisco ACI fabric, which is integrated with vCenter. These configuration steps are complete: - The configured pool of ESXi hosts is…

Updating AAEP to AEP_VMM on policy groups for bare-metal servers would change their association, potentially breaking existing bare-metal server configurations, and might not be the correct way to extend VMM integration if AEP_BAREMETAL is specifically designed for these new nodes.

Creating a new AAEP container object for policy groups for AEP_VMM is a configuration step for organizing AAEPs, but it does not directly extend VMM integration to specific nodes or AAEPs.

Implementing a separate VMM domain for bare-metal servers using AEP_VMM would duplicate VMM integration efforts and is not necessary when an existing VMM domain should simply be associated with the relevant AAEP.

For bare-metal ESXi servers, which are being treated similarly to traditional bare-metal servers in terms of ACI policy application, their associated AAEP (AEP_BAREMETAL) needs to be linked to the VMM domain. This association is crucial because the VMM domain connects ACI's logical policies to the virtual machine manager (vCenter), allowing ACI to push network policies to the ESXi hosts that are part of that VMM domain. By adding the VMM domain under the AEP_BAREMETAL AAEP object, all interfaces associated with AEP_BAREMETAL will inherit the VMM domain's policies and settings, enabling the bare-metal ESXi hosts to participate in the VMM integration.
