he data path of the fabric which means that even in the absence of the controllers the data path will not be affected. The fabric consists of 40 Gbps. High bandwidth links between leaf & Spine Switches with no link connecting between Leaf to Leaf or Spine to Spine. 9k platform switches - 9500 & 9300 Series Nexus Switches that operates either in NXOS Mode or ACI mode. Features That Define APIC APIC is the controller for the ACI Fabric. APIC is not under the data path of the fabric. APIC is not the control plane of the ACI Infrastructure. Figure 2.

APIC is the controller where the entire management of the fabric is abstracted. ACI policy model approach automatically provides the policies in the ACI Infrastructure SO when the change occurred to the fabric APIC applies that change to the ACI Policy Model, the policy model afterwards initiates the change to the managed endpoint. It also gives the ability to integrate the Layer4 -Layer7 services either in unmanaged or managed way with device packages available. There are three primary ways to access the APIC Controller: Figure 4.
