Cisco ACI with Cisco UCSM Integration

Beginning in Cisco APIC Release 4.1(1), you can automate networking policies on Cisco UCS devices. To do so, you integrate Cisco UCSM into the Cisco Application Centric Infrastructure (ACI) fabric. Cisco APIC takes hypervisor NIC information from the Cisco UCSM and a virtual machine manager (VMM). The automation applies to all the devices that the Cisco UCSM manages.
