About In-Band and Out-of-Band Management
You can use in-band or out-of-band when designing the management plane and connectivity for the Cisco Application Centric Infrastructure (ACI) fabric. Out-of-band management utilizes its own set of specific ports that only exist on the out-of-band management plane. There is no configuration available to merge the out-of-band management plane into the data plane of the ACI fabric. Out-of-band management typically has its specifics ports connected to a device that only manages out-of-band network traffic.
